2024-08-02 21:37:59 | Threat Actor Abuses Cloudflare Tunnels to Deliver RATs (lien direct) | ## Snapshot Researchers at Proofpoint have observed an increase in malware delivery via TryCloudflare Tunnel abuse. The threat activity is unattributed at this point in time but is financially motivated and delivers remote access trojans (RATs). ## Description The threat actors have modified tactics, techniques, and procedures to bypass detection and improve efficacy. The activity abuses the TryCloudflare feature to create a one-time tunnel without creating an account, allowing the delivery of malware. The campaigns lead to the delivery of Xworm, a remote access trojan (RAT), and other malware such as AsyncRAT, VenomRAT, GuLoader, and Remcos. The threat actor behind the campaigns has been observed modifying different parts of the attack chain to increase sophistication and defense evasion. The use of Cloudflare tunnels provides the threat actors with a way to use temporary infrastructure to scale their operations, making it harder for defenders to detect and take down instances in a timely manner. The attack chain requires significant victim interaction, giving the recipient multiple opportunities to identify suspicious activity and disrupt the attack chain before successful execution. ## Microsoft Analysis ProofPoint\'s findings fit with the trend [other security researchers]([https:/security.microsoft.com/intel-explorer/articles/7f0d7aa3]) have noted of hackers utilizing DNS tunneling as a covert communication method and for bypassing traditional security measures. Although ProofPoint does not attribute the activity to a tracked Threat Actor, Microsoft Threat Intelligence has also observed threat actors such as [Aqua Blizzard](https://sip.security.microsoft.com/intel-profiles/9b01de37bf66d1760954a16dc2b52fed2a7bd4e093dfc8a4905e108e4843da80) (ACTINIUM) utilize Cloudflare tunnels to obfuscate their command and control (C2) communication. The process began with phishing activities that downloaded the cloudflared.exe client, which doesn\'t require configuration or licensing. This client sets up a tunnel through Cloudflare\'s infrastructure, masking the connection to the C2 IP address and making it difficult for network security software to detect the threat actor\'s infrastructure. ## Detections/Hunting Queries Microsoft Defender Antivirus detects threat components as the following malware: - [Trojan:VBS/XWorm](https://www.microsoft.com/en-us/wdsi/threats/malware-encyclopedia-description?Name=Trojan:VBS/XWorm) - [Trojan:Win32/Guloader](https://www.microsoft.com/en-us/wdsi/threats/malware-encyclopedia-description?Name=Trojan:Win32/Guloader) - [Backdoor:JS/Remcos](https://www.microsoft.com/en-us/wdsi/threats/malware-encyclopedia-description?Name=Backdoor:JS/Remcos) - [Trojan:Win32/Remcos](https://www.microsoft.com/en-us/wdsi/threats/malware-encyclopedia-description?Name=Trojan:Win32/Remcos) - [PWS:Win32/Remcos](https://www.microsoft.com/en-us/wdsi/threats/malware-encyclopedia-description?Name=PWS:Win32/Remcos) - [Backdoor:MSIL/Remcos](https://www.microsoft.com/en-us/wdsi/threats/malware-encyclopedia-description?Name=Backdoor:MSIL/Remcos) - [Backdoor:Win32/Remcos](https://www.microsoft.com/en-us/wdsi/threats/malware-encyclopedia-description?Name=Backdoor:Win32/Remcos) - [TrojanDownloader:O97M/Remcos](https://www.microsoft.com/en-us/wdsi/threats/malware-encyclopedia-description?Name=TrojanDownloader:O97M/Remcos) - [TrojanDownloader:AutoIt/Remcos](https://www.microsoft.com/en-us/wdsi/threats/malware-encyclopedia-description?Name=TrojanDownloader:AutoIt/Remcos) - [Trojan:XML/AsyncRat](https://www.microsoft.com/en-us/wdsi/threats/malware-encyclopedia-description?Name=Trojan:XML/AsyncRat) - [Backdoor:Win32/Asyncrat](https://www.microsoft.com/en-us/wdsi/threats/malware-encyclopedia-description?Name=Backdoor:Win32/Asyncrat) - [Trojan:VBS/AsyncRAT](https://www.microsoft.com/en-us/wdsi/threats/malware-encyclopedia-description?Name=Trojan:VBS/AsyncRAT) - [Trojan:VBA/AsyncRAT](https://www.microsoft.com/en-us/wdsi/threats/malware-encyclopedia-descript | Spam Malware Tool Threat Prediction | ||

2024-08-02 20:39:07 | Black Basta ransomware switches to more evasive custom malware (lien direct) | ## Instantané Le Black Basta Ransomware Gang a été une menace mondiale importante, responsable de plus de 500 attaques réussies contre les entreprises du monde entier selon le site de fuite de données Black Basta.Le groupe utilise une stratégie à double extension, combinant le vol de données et le chiffrement et exige des paiements de rançon importants.Black Basta a été observé en utilisant des outils accessibles au public aux logiciels malveillants personnalisés développés en interne. ## Description Des recherches chez Mandiant Suspects Black Basta utilisent un modèle d'affiliation privé à invitation fermée pour distribuer des ransomwares de Basta, se différenciant des ransomwares traditionnels commercialisés en tant que service (RAAS).Mandiant nommé "UNC4393" comme principal utilisateur de [BASTA Ransomware] (https://security.microsoft.com/intel-profiles/0146164ed5ffa131074fa7e985f779597d2522865baaa088f25cd80c3Ded8d726).UNC4393, également connu sous le nom de Cardinal Cybercrime Group, est suivi par Microsoft sous le nom de [Storm-1811.] (Https://security.microsoft.com/intel-profiles/0a78394b205d9b9d6cbcbd5f34053d7fc1912c3fa7418ffd0ebf1d00f67777718 Initialement, le Black Basta Gang s'est associé à la [Qakbot (également connu sous le nom de QBOT)] (https: // Security.microsoft.com/intel-profiles/65019CE99508DD6A7ED35BA221524B6728A564600616C7229BAA0ECDEC21701B) pour l'accès réseau Distribution de Botnet en botnetFections via des e-mails de phishing et de la contrebande de HTML, mais après [les forces de l'ordre ont perturbé Qakbot] (https://www.bleepingcomputer.com/news/security/how-the-fbi-nuked-qakbot-malware-from-infected-windows-pcs/), ils ont dû former de nouveaux partenariats pour violer les réseaux d'entreprise.Black Basta est passé à des grappes de distribution d'accès initiales comme celles qui livrent [Darkgate] (https://sip.security.microsoft.com/intel-profiles/52fa311203e55e65b161aa012eba65621f91Be78) MALAFACT.Quelques mois plus tard, le groupe est passé de Darkgate via le phishing au malvertising à l'aide de Silentnight, un malware de porte dérobée.Silentnight (alias Terdot et Deloader), passe également par [Zloader] (https://security.microsoft.com/intel-profiles/cbcac2a1de4e52fa5fc4263829d11ba6f2851d6822569a3d3ba9669e72aff789).Zloader est remarquable pour sa capacité à s'adapter à différentes campagnes.Les logiciels malveillants de porte dérobée ont été observés dans les campagnes de phishing à des campagnes de malvertising plus récentes comme le Ransomware Black Basta. Des outils et tactiques supplémentaires de Basta noirs ont évolué pour inclure l'utilisation d'un compte-gouttes sur la mémoire personnalisé nommé DawnCry, qui a lancé une infection en plusieurs étapes, suivie de Daveshell, qui a conduit au Portyard Tunneler qui se connecte à la commande noire de Black \\et contrôle (C2).D'autres outils personnalisés remarquables utilisés dans les opérations récentes incluent COGSCAN, [SystemBC] (https://security.microsoft.com/intel-profiles/530f5cd2221c4bfcf67ea158a1e674ec5a210dbd611dfe9db652c9adf97292b), knknotrock.En outre, le gang continue d'utiliser des binaires "vivant hors du terrain" et des outils facilement disponibles dans leurs dernières attaques, y compris l'utilitaire de ligne de commande Windows Certutil pour télécharger Silentnight et le [Rclone] (https://security.microsoft.com/Intel-Profiles / 3C39892A30F3909119605D9F7810D693E502099AE03ABBD80F34D6C70D42D165) Tool to Exfiltrate Data.

2024-08-02 20:30:41 | Social Media Malvertising Campaign Promotes Fake AI Editor Website for Credential Theft (lien direct) | ## Snapshot Researchers at Trend Micro identified a malvertising campaign where threat actors hijack social media pages, rename them to mimic popular AI photo editors, and post malicious links to fake websites. ## Description These attackers use spam messages with phishing links to steal admin credentials, leading to fake account protection pages. Once they gain control, they post ads promoting the AI photo editor, which directs victims to download an endpoint management utility disguised as the photo editor. The ITarian software is then used to execute additional payloads like Lumma Stealer, which exfiltrates sensitive data such as cryptocurrency wallet files, browser data, and password manager databases. This campaign exploits the popularity of AI tools by using them as lures for malicious activities. Cybercriminals have been observed changing social media page names to those of popular AI tools and using paid ads to boost their malicious posts. Victims are tricked into downloading software that allows attackers to remotely control their devices, leading to data and credential theft. ## Additional Analysis Threat actors frequently capitalize on current trends and events to enhance the credibility of their phishing scams, and the recent surge in interest around AI is no exception. By leveraging the excitement surrounding new AI technologies, cybercriminals create convincing phishing sites and promotional materials that mimic legitimate AI platforms. These scams often employ sophisticated social engineering tactics, including the use of compromised social media accounts, to distribute malware under the guise of AI applications. Security researchers at [Cyble Research and Intelligence Labs](https://cyble.com/blog/threat-actors-exploit-sora-ai-themed-branding-to-spread-malware/) have observed cybercriminals using branding for OpenAI\'s Sora, to create convincing phishing sites promoted through compromised social media accounts. This strategy not only increases the perceived legitimacy of their malicious campaigns but also exploits the public\'s eagerness to engage with cutting-edge technologies, thereby maximizing the reach and impact of their attacks. ## Recommendations Microsoft recommends the following mitigations to reduce the impact of this threat. - Turn on [cloud-delivered protection](https://learn.microsoft.com/en-us/defender-endpoint/linux-preferences) in Microsoft Defender Antivirus or the equivalent for your antivirus product to cover rapidly evolving attacker tools and techniques. Cloud-based machine learning protections block a majority of new and unknown threats. - Run [EDR in block mode](https://learn.microsoft.com/microsoft-365/security/defender-endpoint/edr-in-block-mode?view=o365-worldwide?ocid=magicti_ta_learndoc) so that Microsoft Defender for Endpoint can block malicious artifacts, even when your non-Microsoft antivirus does not detect the threat or when Microsoft Defender Antivirus is running in passive mode. EDR in block mode works behind the scenes to remediate malicious artifacts that are detected post-breach. - Allow [investigation and remediation](https://learn.microsoft.com/microsoft-365/security/defender-endpoint/automated-investigations?view=o365-worldwide?ocid=magicti_ta_learndoc) in full automated mode to allow Microsoft Defender for Endpoint to take immediate action on alerts to resolve breaches, significantly reducing alert volume. - [Enable](https://learn.microsoft.com/en-us/defender-endpoint/enable-controlled-folders) controlled folder access. - Ensure that [tamper protection](https://learn.microsoft.com/en-us/defender-endpoint/prevent-changes-to-security-settings-with-tamper-protection#how-do-i-configure-or-manage-tamper-protection) is enabled in Microsoft Defender for Endpoint. - Enable [network protection](https://learn.microsoft.com/en-us/defender-endpoint/enable-network-protection) in Microsoft Defender for Endpoint. - Follow the credential hardening recommendations in the [on-premises credential theft overview](http | Ransomware Spam Malware Tool Threat Prediction | ||

#### Géolocations ciblées - Corée - Amérique du Nord - Moyen-Orient - L'Europe de l'Est - Europe du Nord - Europe du Sud - Europe de l'Ouest #### Industries ciblées - Informatique - Produits informatiques et services ## Instantané Les chercheurs de Securonix ont découvert une campagne de [Dev # Popper] (https://security.microsoft.com/intel-explorer/articles/7309c) par des acteurs de la menace nord-coréenne, ciblant les développeurs de logiciels par le biais de techniques avancées d'ingénierie sociale. ## Description La campagne est répandue et a eu un impact sur les victimes en Corée du Sud, en Amérique du Nord, en Europe et au Moyen-Orient.De plus, la campagne a élargi son pool de victimes pour cibler les utilisateurs de Windows, Linux et MacOS.L'attaque est lancée par de fausses entretiens d'embauche, où les acteurs de la menace présentent à la personne interrogée un package de fichiers zip contenant des logiciels malveillants. Ce malware utilise un code JavaScript fortement obscurci, C2 Communications, Téléchargements de charge utile et exécution Python, avec de nouvelles fonctionnalités de persistance à l'aide de AnyDesk RMM.Le logiciel malveillant basé sur Python comprend des capacités de vol de données sensibles, une prise en charge du système multi-opératoires, une obscurité améliorée et un codage, un réseau, une exécution de commande distante, une exfiltration de données, une journalisation du presse-papiers et des casques de touche et une fonctionnalité FTP étendue.La campagne implique également l'abus des tactiques d'ingénierie sociale et l'extraction des références stockées et des cookies de session de divers navigateurs. ## Analyse Microsoft Les acteurs de la menace exploitent de plus en plus des outils légitimes dans leurs cyberattaques, en particulier les outils de surveillance et de gestion à distance (RMM) comme AnyDesk.Ces outils, conçus à des fins de support informatique et administratifs, offrent aux attaquants un moyen d'obtenir un accès persistant et souvent non détecté aux systèmes cibles.En utilisant des outils RMM, les cybercriminels peuvent contrôler à distance les appareils compromis, exécuter des commandes et exfiltrater les données sans augmenter les suspicions immédiates car ces outils sont couramment utilisés dans les environnements commerciaux. Anydesk, en particulier, a été utilisé pour maintenir un accès à long terme, contourner les mesures de sécurité traditionnelles et se fondre dans un trafic réseau régulier.Cette approche améliore non seulement la furtivité de leurs opérations, mais complique également les efforts de détection et d'atténuation pour les professionnels de la sécurité. Microsoft a observé un certain nombre de groupes de cybercrimins et de groupes d'activités de l'État-nation utilisant des outils RMM dans le cadre de leurs attaques.Notamment, [Lemon Sandstorm] (https://security.microsoft.com/intel-profiles/0d4189e06940820f500aaad47d944280b34339bc24e7608df130c202bb36f2fa), un groupe d'activités national-state à partir de l'IRAN, [TEMPER-1] (HTTTS] (HTTT ecurity.microsoft.com/ Intel-Profiles / E056344786FAB8E389EACCBCB99C39A2764BB85B26AA55013D968E12FBD073AE), un groupe cybercriminal connu pour le déploiement de Lockbit et [BlackSuit] (https://Secucule.Microsoft.com.

The days of a one-size fits all security awareness program are over. The State of the Phish report from Proofpoint notes that over 98% of businesses have a security awareness program. Yet a staggering 68% of users say they take risky actions despite knowing the risks. These statistics underscore the frustrations that we hear from prospective clients every day. They tell us that while they run a continuous educational program, they struggle to achieve the desired behavior improvements among their users. Some of the key challenges they face are: Not knowing who represents the greatest risk to the organization Not knowing what policies, threats and vulnerabilities to educate users about at any given moment Not being able to keep a program agile without exhausting resources, constantly updating user groups or continually tailoring curriculums These issues highlight the critical need to go beyond traditional security awareness and think holistically to build a human risk management program. A good place to start is focusing on highly targeted user groups. It\'s these users who are often the ones responsible for most of the security issues within a business. When you can tailor education to the specific needs of these users, you can mitigate individual vulnerabilities. You can also fortify your entire defense against potential attacks. A new workflow from Proofpoint focuses on these users to produce exponentially positive results in helping you reduce overall risk. In this blog, we\'ll explore why focusing on human risk management is so important. And we\'ll explain how Proofpoint can help you do just that. What is human risk management? Human risk management builds on existing security best practices to automate cyberattack prevention and response. What makes it different is that it places people at the center. Fundamental to a human risk management solution is an ability to ingest user event and identity activity across multiple security tools within a given environment. The solution will track: Attack risk. The likelihood a user will be attacked Vulnerability risk. The likelihood that the attack may be successful Privilege risk. The damage that a successful attack may cause the organization Then it quantifies an overall risk score for each individual. With this insight, companies and their security teams can: Gain visibility into which individuals or groups are prime targets and prioritize strategies to best protect them Intervene with technical controls to immediately prevent a risky action or provide contextual nudges that advise users about their risks and how to avoid them Automatically enroll risky users into tailored education curriculums, which empowers them to protect themselves and the company against future cyberattacks Easily track improvements in user behaviors and foster a positive security culture These are the issues that the new Adaptive Threat and User-Risk Response Workflow within Proofpoint Security Awareness is designed to address. In short, this new workflow lets you take advantage of everything that is great about Proofpoint. Our Adaptive Threat and User-Risk Response Workflow The new workflow integrates three core capabilities. It enables you to: Dynamically create and manage user groups based on the user risk profiles and groups derived from Proofpoint Nexus People Risk Explorer (NPRE) and Proofpoint Targeted Attack Protection (TAP) using Adaptive Groups Create a threat-driven educational curriculum based on the defined Threat Families tracked by our own Threat Research and reported via TAP Build an Adaptive Assignment to auto-enroll new users into the curriculum whenever a new user qualifies for the previously created Adaptive Group This adaptive learning approach prioritizes education for highly targeted groups.

2024-08-02 00:53:15 | Un nouvel outil Specula utilise Outlook pour l'exécution du code distant sous Windows New Specula tool uses Outlook for remote code execution in Windows (lien direct) |
## Instantané
TrustEdSec a identifié un nouveau cadre post-exploitation de l'équipe rouge appelée "Specula", qui tire parti d'une vulnérabilité dans Microsoft Outlook pour exécuter à distance le code en définissant des pages d'accueil malveillantes via des modifications du registre.
## Description
Le nouveau cadre de spéculations exploite [CVE-2017-11774] (https://sip.security.microsoft.com/vulnerabilities/vulnerabilité/CVE-2017-11774/overview), une fonctionnalité de sécurité de contournement de la vulnérabilité dans Outlook qui permet aux acteurs de menace àDéfinissez une page d'accueil Outlook personnalisée via des clés de registre et exécutez VBScript ou JScript pour exécuter des commandes arbitraires sur des systèmes Windows compromis.Bien qu'ils soient corrigés, les attaquants peuvent toujours créer des pages d'accueil malveillantes en utilisant des valeurs de registre Windows, leur permettant de réaliser de la persistance et de se propager latéralement à d'autres systèmes.La méthode est remarquable pour sa capacité à contourner les logiciels de sécurité en tirant parti de l'état du processus de confiance d'Outlook.
Pour que Specula exécute avec succès le code distant, les attaquants doivent d'abord compromettre une machine pour accéder.
En 2018, la vulnérabilité des perspectives du CVE-2017-11774 a été utilisée pour cibler les agences gouvernementales américaines et a été liée au groupe de cyber-espionnage APT33 parrainé par l'Iran par les chercheurs en sécurité de Chronicle, Fireeye et Palo Alto.
## Recommandations
La source fournit les recommandations suivantes:
- Tout d'abord, si possible pour votre organisation, commencez à utiliser la nouvelle Outlook \\ '\\.
- Deuxièmement, dans les versions à venir de Windows 11, le moteur VBScript sera un composant qui peut être supprimé et paralysera ce vecteur d'attaque car VBScript est nécessaire pour exécuter le code.
- Troisièmement, l'objet de stratégie de groupe (GPO) peut être utilisé pour configurer les clés associées et définir d'autres qui désactivent purement WebView.
- La quatrième option consiste à tirer parti des lignes de base dans la boîte à outils de conformité Microsoft Security.Lors des tests, les lignes de base semblent avoir verrouillé le moteur Web que Outlook utilise pour rendre HTML et VBScript, ce qui ne fait pas d'exécuter les scripts.

2024-08-01 10:25:29 | Création de déploiements de kubernetes évolutifs avec des mesures personnalisées Creating Scalable Kubernetes Deployments with Custom Metrics (lien direct) |
Engineering Insights is an ongoing blog series that gives a behind-the-scenes look into the technical challenges, lessons and advances that help our customers protect people and defend data every day. Each post is a firsthand account by one of our engineers about the process that led up to a Proofpoint innovation. Proofpoint Enterprise Archive offers a central, searchable repository that allows ingestion and meets Financial Industry Regulatory Authority (FINRA) standards for compliance. This blog explores how we achieved scale using Kubernetes as our deployment platform. Kubernetes and Horizontal Pod Autoscaler (HPA) Kubernetes is an open-source platform that provides straightforward container orchestration, scalability, resilience and fault tolerance for microservices. All of these factors made it a clear choice as a deployment platform for our application. HPA in Kubernetes is a built-in feature that automatically adjusts the number of replicas (pods) of a deployment based on observed metrics. In a regular environment, HPA queries the Kubernetes metric server, calculates the intended number of replicas and updates a deployment with a desired replica count. The deployment scales the pod count to the desired value. Horizontal Pod Autoscaler (HPA) in Kubernetes. Scaling a deployment based on custom metrics Autoscaling solutions are typically based on runtime metrics like CPU load. However, built-in system metrics are not always adequate for making autoscaling decisions. You need custom metrics to make useful autoscaling decisions. The Proofpoint Enterprise Archive includes a task scheduling system that takes tasks from the queue and executes them one by one. CPU-based autoscaling might not be optimal here because: Tasks can be IO-bound, not CPU-bound Tasks can have priorities, schedules and deadlines For prolonged periods, NO tasks might be scheduled to run at all; in this case, the scaling solution ideally would downscale to zero pods Another applicable scenario would be to scale proactively based on an artificial intelligence (AI) system that predicts load based on past usage patterns. For our use case, the tasks queue length can be a better metric to make scaling decisions, but it requires a custom queue length metric. Although you can set up Kubernetes HPA for this type of scaling, it can be challenging to implement custom metrics for scaling. Furthermore, HPA does not support scaling down to zero pods, which is essential to manage costs. Kubernetes Event Driven Autoscaling (KEDA) is a complementary autoscaling technology you can integrate into HPA. It offers a wide variety of scalers that can fetch metrics from various sources, including Prometheus monitors. KEDA uses these metrics for its integration with Kubernetes HPA. KEDA using its Prometheus Scaler to query metrics from Prometheus. The diagram above shows KEDA using its Prometheus Scaler to query metrics from Prometheus. In our system, the external metrics are mostly exposed by the application itself. KEDA uses these metrics to manage the HPA thereby indirectly controlling the pods\' replica count. KEDA also allows scaling the pods to zero by simply deleting the HPA object. When metrics demand the creation of pods, KEDA recreates the HPA object and starts to manage it. Sample definition and scaling behavior of a processor As a scaling example, we will show a background task processor (BTP) that waits for customer-driven events, picks them up and processes them. It is idle when there are no events to process. Our application exposes metrics that signal when and how many processors are required to handle customer events at any given time. Prometheus scrapes these metrics and makes them available to KEDA for processing.

2024-08-01 01:09:55 | Sceau de menthe: une étude complète d'un voleur d'informations basé sur un python Mint Stealer: A Comprehensive Study of a Python-Based Information Stealer (lien direct) |
## Snapshot Researchers at Cyfirma have identified Mint Stealer, an [information-stealing malware](https://sip.security.microsoft.com/intel-profiles/2296d491ea381b532b24f2575f9418d4b6723c17b8a1f507d20c2140a75d16d6) operating within a malware-as-a-service (MaaS) framework. Mint Stealer is designed to covertly exfiltrate a wide-range of sensitive data from compromised systems, including web browser data, cryptocurrency wallet details, gaming credentials, VPN client information, messaging app data, FTP client data, and more. ## Description Mint-stealer\'s capabilities include capturing system information, detecting debuggers and analysis tools, continuously capturing clipboard data through PowerShell commands, encrypting exfiltrated data, and communicating with its C2 server for updates and instructions. Mint Stealer is created using the Nuitka Python compiler and relies on Python dynamic modules to support its functionality. The initial payload acts as a dropper, with the main payload hidden in a compressed form within the resources section of the executable. It uploads stolen data to free file-sharing websites and communicates with its command-and-control server (C2) for updates and instructions. The threat actor behind Mint Stealer is associated with another malware-selling website, cashout\[.\]pw, and offers hosting services that do not respect DMCA requests. ## Microsoft Analysis In recent years, Microsoft has tracked the growing risk that infostealers pose to enterprise security. Infostealers are commodity malware used to steal information from a target device and send it to the threat actor. The popularity of this class of malware led to the emergence of an infostealer ecosystem and a new class of threat actors who leveraged these capabilities to conduct their attacks. Often, infostealers are advertised as a malware as a service (MaaS) offering – a business model where the developers lease the infostealer payload to distributers for a fee. The new class of actors enabled by the infostealer ecosystem demonstrate that it is possible to gain initial access to an organization with minimal native malware development skills, by purchasing tools already available. Information stealers are versatile and can be distributed in various forms including through phishing email campaigns, malvertising, and trojanized software, games and tools. They can target a range of information like session tokens and cookies, saved passwords, financial information, and credentials for internet-facing systems and applications. ## Detections/Hunting Queries ### Microsoft Defender Antivirus Microsoft Defender Antivirus detects threat components as the following malware: - Trojan:Win32/Casdet ### Microsoft Defender for Endpoint Alerts with the following titles in the security center can indicate threat activity on your network: - Information stealing malware activity ## Recommendations Microsoft recommends the following mitigations to reduce the impact of this threat.

## Snapshot This report presents an analysis of recent trends in cyber threats based on 111 articles published by threat researchers across the security community between April and June 2024. These articles are curated by Microsoft Threat Intelligence from across a number of trusted sources and included in Microsoft Defender Threat Intelligence as open source intelligence (OSINT) articles. The analysis focuses on the nearly 1,000 MITRE ATT&CK framework tags correlated to the content in each article. By distilling insights from these tags and the related intelligence, we can highlight prevalent tactics, techniques, and procedures (TTPs) observed in the cyber security landscape over the past quarter. This dataset is not exhaustive but represents a curated set of most high-profile cyber threat intelligence reporting from across the security community. When prioritizing cyber security efforts, it\'s essential to understand the trending TTPs observed in the wild. This knowledge helps defenders make informed decisions about the most effective strategies to implement, especially where to focus engineering efforts and finite resources. ## Activity Overview - **Initial access: Phishing**: Phishing remains a prevalent initial access method, mentioned in a third of reports, including spear-phishing attachments and links. The persistence of this technique underscores its effectiveness and the ongoing need for robust user education and email security measures. - **Defense evasion: Obfuscated files or information:** Over a third of reports highlighted the use of obfuscation techniques, such as dynamic API resolution and steganography, to evade detection. This trend is likely underpinned by factors such as the cybercrime market for obfuscating even basic credential theft malware as well as the growing sophistication in some malware to bypass traditional security measures. - **Command and control: Ingress tool transfer:** Ingress tool transfer was the most frequently referenced technique, involving the transfer of tools from an external system to a compromised one. Key threats driving the prevalence of this tactic included an increase in OSINT reporting on threat actors misusing the ms-appinstaller URI scheme (App Installer) to distribute malware. - **Execution: Command and scripting interpreter/PowerShell:** Execution through PowerShell was prominent, continuing its trend of broad adoption in attacks over the past decade. The widespread adoption of PowerShell to launch malicious code is in part due to numerous toolkits that have been developed to allow quick deployment of a wide range of attacks. - **Exfiltration: Exfiltration over C2 channel:** The most commonly referenced exfiltration method was over the command-and-control (C2) channel, highlighting the critical need for network monitoring and anomaly detection to identify and mitigate data breaches. The frequent reports on infostealers such as Lumma and DarkGate-commodity malware used to steal information from a target device and send it to the threat actor-are likely key drivers of this MITRE tag\'s prominence. - **Impact: Data encrypted for impact:** Ransomware involving data encryption was the most frequently observed impact technique, with LockBit and other groups exploiting vulnerabilities. The use of Bring Your Own Vulnerable Driver (BYOVD) tactics, such as Warp AV Killer, remained common. #### Initial access: Phishing Phishing remains a significant initial access method in open-source research, with a third of the reports mentioning its use. This includes both spear-phishing attachments and spear-phishing links. Phishing involves deceptive attempts to trick individuals into divulging sensitive information or installing malicious software, often through seemingly legitimate emails. The persistence of this technique underscores its effectiveness and the ongoing need for robust user education and email security measures.

## Snapshot In a coordinated report, Guardio Labs and Proofpoint detailed spam campaigns, which exploited weak permissions in Proofpoint\'s email protection service to send millions of spoofed emails impersonating major entities like Disney, Nike, IBM, and Coca-Cola to Fortune 100 companies. ## Description The campaign, which began in January 2024, involved an average of 3 million spoofed emails per day, peaking at 14 million emails in early June. Threat actors utilized their own SMTP (Simple Mail Transfer Protocol) servers to create spoofed emails with manipulated headers and relayed them through compromised or rogue Microsoft Office 365 accounts via Proofpoint\'s relay servers. As of July 30th, Guardio Labs reported that a number of the Microsoft accounts have been removed. The attackers leveraged Virtual Private Servers (VPS) hosted by OVHCloud and Centrilogic, as well as various domains registered through Namecheap to conduct the campaign. Proofpoint assesses that this activity was likely conducted by one actor, who is currently unknown. The phishing emails were designed to steal sensitive personal information and incur unauthorized charges, and they passed SPF and DKIM checks, allowing them to bypass spam filters and reach recipients\' inboxes. Proofpoint, after being notified by Guardio Labs, tightened security measures and provided new settings and advice to mitigate these attacks. ## Recommendations Microsoft recommends the following mitigations to reduce the impact of this threat. - Turn on [cloud-delivered protection](https://learn.microsoft.com/en-us/defender-endpoint/linux-preferences) in Microsoft Defender Antivirus or the equivalent for your antivirus product to cover rapidly evolving attacker tools and techniques.

Their activities have been observed in several regions, including the United States, Europe, and Asia. The Donot group\'s motivations are information theft and espionage. The group is known for targeting Pakistani users with Android malware named StealJob, disguised under the name “Kashmiri Voice” to steal confidential information and intellectual property. In July 2022, they used Comodo\'s certificate to sign their spyware, demonstrating their high level of technical skill. The Donot APT group employs various tactics such as spear-phishing emails, malware, and custom-developed tools, often using third-party file-sharing websites for malware distribution. They are well-funded and use sophisticated techniques to evade detection, including encryption and file-less malware. ## Additional Analysis According to a number of additional sources, Donot group is likely [linked to the Indian government](https://socradar.io/apt-profile-apt-c-35-donot-team/). Initial access to victim environments is typically achieved through phishing campaigns and the group has been observed exploiting vulnerabilities in Microsoft Office, including [CVE-2018-0802](https://security.microsoft.com/intel-explorer/cves/CVE-2018-0802/), [CVE-2017-0199](https://security.microsoft.com/intel-explorer/cves/CVE-2017-0199/), and [CVE-2017-8570](https://security.microsoft.com/intel-explorer/cves/CVE-2017-8570/). Donot group is a persistent and consistent actor. [ESET researchers](https://www.welivesecurity.com/2022/01/18/donot-go-do-not-respawn/) note the group is known to repeatedly attacks the same target, even if they are removed fromt he victim environment. In some cases, the Donot group launched spearphishing campaigns against targets every two to four months. ## Recommendations Microsoft recommends the following mitigations to reduce the impact of this threat. - Turn on [cloud-delivered protection](https://learn.microsoft.com/en-us/defender-endpoint/linux-preferences) in Microsoft Defender Antivirus or the equivalent for your antivirus product to cover rapidly evolving attacker tools and techniques. Cloud-based machine learning protections block a majority of new and unknown threats. - Run [EDR in block mode](https://learn.microsoft.com/microsoft-365/security/defender-endpoint/edr-in-block-mode?view=o365-worldwide?ocid=magicti_ta_learndoc) so that Microsoft Defender for Endpoint can block malicious artifacts, even when your non-Microsoft antivirus does not detect the threat or when Microsoft Defender Antivirus is running in passive mode.

2024-07-31 15:03:11 | Les fausses mises à jour du navigateur déploient un logiciel Asyncrat et malveillant BOINC Fake Browser Updates Deploy AsyncRAT and Malicious BOINC Software (lien direct) |
## Snapshot Researches at Huntress identified new behaviors associated with SocGholish, or FakeUpdates, malware. Typically, infections start when a user visits a compromised website and downloads a fake browser update, which executes malicious code to download further malware. . ## Description Initial access involves a malicious JavaScript file that downloads subsequent stages of the attack. In this case, two separate chains were identified: one leading to a fileless AsyncRAT installation and the other to a malicious BOINC (Berkeley Open Infrastructure Network Computing Client) installation. The AsyncRAT chain involved several stages with obfuscated PowerShell scripts and anti-VM techniques, eventually leading to a connection to a command and control (C2) server. The BOINC chain involved dropping multiple files, creating directories and scheduled tasks, and renaming executables to disguise their malicious intent. The BOINC software, typically used for legitimate distributed computing projects, was configured to connect to malicious servers, enabling threat actors to collect data and execute tasks on infected hosts. Persistence was maintained through scheduled tasks, and the use of BOINC in this context is relatively unusual. Both chains showed similarities with previous SocGholish activities, such as using fake browser updates and PowerShell scripts. The new campaigns utilized recently registered domains and shared infrastructure noted by other security researchers. ## Microsoft Analysis Microsoft researchers have investigated multiple incidents involving fake software updates served by the SocGholish malware distribution framework. [SocGholish](https://security.microsoft.com/intel-profiles/7e30959d011aa33939afaa2477fd0cd097cee346fa3b646446a6b1e55f0c007f) is an attack framework that malicious attackers have used since at least 2020. The attacker framework entices users to install fake software updates that eventually let attackers infiltrate target organizations. SocGholish can be tweaked to deliver any payload an attacker chooses. Threat actor, [Mustard Tempest](https://security.microsoft.com/intel-profiles/79a9547522d81fe6c1f5e42d828009656892f3976c547360db52c33f0ba16db9?tab=tradeCraft), uses SocGholish/FakeUpdates as their primary technique to gain intial access.

It is designed to evade detection and is often used by attackers to gain unauthorized access to a victim\'s system. AsyncRAT is written in .NET and is capable of running on Windows machines. It can perform various malicious activities such as keylogging, file stealing, and ransomware deployment. Its name comes from its use of asynchronous programming techniques, which allow it to carry out multiple tasks simultaneously without blocking the program\'s main thread.

2024-07-31 10:00:00 | Les attaques de ransomwares sont-elles toujours une menace croissante en 2024? Are Ransomware Attacks Still a Growing Threat in 2024? (lien direct) |
The content of this post is solely the responsibility of the author. LevelBlue does not adopt or endorse any of the views, positions, or information provided by the author in this article. Ransomware attacks continue to pose a growing threat to organizations as it has emerged as the number one threat, affecting 66% of organizations in 2023 and pulling over $1 billion from the victims. These attacks have increased in frequency and sophistication, resulting in significant financial loss, operation disruption, theft of sensitive data, and reduced productivity rates. Also, it damages the organization\'s reputation and results in the loss of customer trust and compliance violations. An organization needs a comprehensive protection strategy to reduce the frequency of these attacks and the risks they pose. Ransomware Business Model: How These Attacks Are Evolving? In the past, ransomware attacks mainly relied on phishing emails, remote desktop protocol exploits, and vulnerable ports to increase their chances of success. Additionally, these attacks employ evasion techniques to bypass traditional security measures like firewalls or antivirus software. These methods have resulted in famous attacks like WannaCry, TeslaCrypt, and NotPetya. With time, ransomware attackers have evolved and have become more sophisticated, targeted, and profitable for cybercriminals. Below is an insight into the latest trends that hackers adopt to launch a successful ransomware attack: Exploiting Zero-Day Vulnerabilities The shift in ransomware gangs and their sophisticated tactics and procedures (TTPs) raise the number of ransomware attacks. . Previously, REvil, Conti, and LockBit were the famous ransomware gangs, but now Clop, Cuban, and Play are gaining immense popularity by employing advanced hacking techniques like zero-day vulnerabilities. Sophos\'s State of Ransomware 2024 revealed exploited vulnerabilities as the root cause of ransomware attacks. The Clop ransomware gang has used the zero-day vulnerability in the MOVEit Transfer platform to steal the sensitive data of different organizations. This group also targeted the GoAnywhere zero-day vulnerability in January 2023, affecting 130 organizations, and exploited the Accellion FTA servers in 2020. Similarly, Cuban and Play used the same attacking technique to compromise the unpatched Microsoft Exchange servers. Double and Triple Extortion Another reason for the rise in ransomware attacks is the introduction of the double or triple extortion technique. Cybersecurity firm Venafi reported that 83% of ransomware attacks included multiple ransom demands in 2022. Cybercriminals encrypt the data, exfiltrate sensitive information, and threaten to release it or sell it on the dark web if the ransom is not paid in a double extortion scheme.

2024-07-30 17:42:47 | (Déjà vu) SideWinder Utilizes New Infrastructure to Target Ports and Maritime Facilities in the Mediterranean Sea (lien direct) | #### Targeted Geolocations - Pakistan - Egypt - Sri Lanka - Bangladesh - Myanmar - Nepal - Maldives #### Targeted Industries - Transportation Systems - Maritime Transportation ## Snapshot The BlackBerry Threat Research and Intelligence team has uncovered a new campaign by the nation-state threat actor SideWinder, also known as Razor Tiger and Rattlesnake, which has upgraded its infrastructure and techniques since mid-2023. ## Description The campaign targets ports and maritime facilities in the Indian Ocean and Mediterranean Sea, with specific focus on Pakistan, Egypt, and Sri Lanka initially, and expanding to Bangladesh, Myanmar, Nepal, and the Maldives. SideWinder employs spear-phishing emails using familiar logos and themes to lure victims into opening malicious documents, which exploit vulnerabilities in Microsoft Office to gain access to systems. The group\'s objective is believed to be espionage and intelligence gathering, consistent with its past campaigns targeting military, government, and business entities in South Asia. The malicious documents use visual bait, such as fake port authority letters, to provoke fear and urgency, leading victims to download malware. The documents exploit a known vulnerability ([CVE-2017-0199](https://security.microsoft.com/intel-explorer/cves/CVE-2017-0199/)) in Microsoft Office, relying on outdated or unpatched systems to deliver their payload. Once opened, the documents download additional malicious files that execute shellcode to ensure the system is not a virtual environment, before proceeding with further stages of the attack. The campaign\'s infrastructure includes the use of Tor nodes to mask network traffic and protective DNS data to evade detection. ## Detections/Hunting Queries ### Microsoft Defender Antivirus Microsoft Defender Antivirus detects threat components as the following malware: - [Exploit:O97M/CVE-2017-0199](https://www.microsoft.com/en-us/wdsi/threats/malware-encyclopedia-description?Name=Exploit:O97M/CVE-2017-0199!MSR) - [Trojan:Win32/Casdet](https://www.microsoft.com/en-us/wdsi/threats/malware-encyclopedia-description?Name=Trojan:Win32/Casdet!rfn) ## Recommendations Microsoft recommends the following mitigations to reduce the impact of this threat. - Turn on [cloud-delivered protection](https://learn.microsoft.com/en-us/defender-endpoint/linux-preferences) in Microsoft Defender Antivirus or the equivalent for your antivirus product to cover rapidly evolving attacker tools and techniques.

CrowdStrike\'s recent update glitch has been exploited by threat actors who use phishing emails to deliver data wipers and remote access tools. A campaign targeting BBVA bank customers distributed the Remcos RAT under the guise of a CrowdStrike Hotfix, while the pro-Iranian hacktivist group Handala used similar tactics against Israeli companies. These attacks, stemming from a logic error in a channel file update, have significantly impacted millions of Windows systems across various sectors.
## Description
AnyRun has identified the exploitation of CrowdStrike\'s update issue by threat actors, including phishing emails and malware campaigns targeting organizations with data wipers and remote access tools. Phishing emails have been observed attempting to take advantage of the disruption, with a malware campaign targeting BBVA bank customers offering a fake CrowdStrike Hotfix update that installs the Remcos RAT. The pro-Iranian hacktivist group Handala has also leveraged the situation by sending phishing emails that impersonate CrowdStrike to Israeli companies to distribute the data wiper. Additionally, attackers are distributing a data wiper under the pretense of delivering an update from CrowdStrike, decimating systems by overwriting files with zero bytes and reporting it over Telegram.
The defect in CrowdStrike\'s software update had a massive impact on Windows systems at numerous organizations, making it too good an opportunity for cybercriminals to pass. The cause of the outage was identified as a channel file update to Windows hosts triggering a logic error, leading to a crash. The impact on Windows systems at numerous organizations was significant, with millions of devices affected and disruptions across various sectors.

2024-07-29 20:15:06 | SeleniumGreed: Threat actors exploit exposed Selenium Grid services for Cryptomining (lien direct) | ## Snapshot
Wiz researchers identified a threat campaign, referred to as "SeleniumGreed," exploiting a misconfiguration in Selenium Grid, a widely used web app testing framework, to deploy a modified XMRig tool for mining Monero cryptocurrency.
## Description
The attackers leverage the lack of default authentication in Selenium Grid to access app-testing instances, download files, and execute commands. By manipulating the Selenium WebDriver API, threat actors establish a reverse shell, drop a custom XMRig miner, and use compromised Selenium node workloads as intermediate command and control servers (C2) for subsequent infections and mining pool proxies. The campaign targets older versions of Selenium but is also possible on more recent versions, potentially evading detection by targeting less maintained and monitored instances.
## Additional Analysis
[XMRig miner](https://www.checkpoint.com/cyber-hub/threat-prevention/what-is-malware/xmrig-malware/) is a popular open-source software designed for mining cryptocurrencies, particularly Monero (XMR). Developed in C++, XMRig is efficient and versatile, supporting various algorithms, mining pools, and running on multiple platforms like Windows, Linux, and macOS. However, it has been widely misused by cybercriminals who deploy it through malware to hijack the computing resources of unsuspecting victims, a practice known as cryptojacking. This unauthorized use of systems significantly degrades performance, increases energy consumption, and can cause hardware damage over time. Due to its frequent abuse in malicious campaigns, XMRig miner has become a focal point in discussions about cybersecurity threats related to resource hijacking and cryptomining.

2024-07-29 20:07:18 | Lumma Stealer Packed with CypherIt Distributed Using Falcon Sensor Update Phishing Lure (lien direct) | ## Snapshot CrowdStrike Intelligence identified a phishing domain which impersonates CrowdStrike and delivers malicious ZIP and RAR files that ultimately executes Lumma Stealer packed with CypherIt. Read more about [Lumma Stealer here.](https://security.microsoft.com/intel-profiles/33933578825488511c30b0728dd3c4f8b5ca20e41c285a56f796eb39f57531ad) ## Description The campaign is likely linked to a June 2024 Lumma Stealer distribution campaign in which a threat actor leveraged advanced social-engineering techniques, such as using spam floods and voice phishing (vishing), to deliver malicious binaries. The MSI loader displays a decoy installation and upon execution, it extracts and executes a self-extracting RAR (SFX) file, plenrco.exe, with the command line plenrco.exe -pqwerty2023 -s1. This extracts another RAR SFX archive file stored in the PE overlay plenrco.exe. The RAR archive contains a Nullsoft Scriptable Install System (NSIS) installer with the filename SymposiumTaiwan.exe. The NSIS installer contains fragments of a legitimate AutoIt executable and a compiled AutoIt script. The NSIS also contains a batch script loader named Open.cmd, which includes useless code to hide the actual functionality. The final payload is RC4-encrypted and LZNT1-compressed, resulting in a Lumma Stealer sample. The decompiled AutoIt script is a CypherIt loader that is heavily obfuscated to hinder static analysis. The loader implements string obfuscation and terminates if certain checks are met, such as specific hostnames or antivirus processes running. The AutoIt loader contains two shellcodes for 32-bit and 64-bit systems that implement the RC4 algorithm to decrypt the final payload, which is also hardcoded within the AutoIt loader. The final payload is a Lumma Stealer executable that contacts the command-and-control (C2) server included in IOCs at the time of analysis. Additionally, the same C2 domain identified in this activity was observed in a recent widespread opportunistic spam flood and voice phishing (vishing) campaign in June 2024. Based on the shared infrastructure between the campaigns and apparent targeting of corporate networks, CrowdStrike Intelligence assesses with moderate confidence that the activity is likely attributable to the same unnamed threat actor. ## Recommendations Microsoft recommends the following mitigations to reduce the impact of this threat. Check the recommendations card for the deployment status of monitored mitigations. - Turn on [cloud-delivered protection](https://learn.microsoft.com/microsoft-365/security/defender-endpoint/configure-block-at-first-sight-microsoft-defender-antivirus?ocid=magicti_ta_learndoc) in Microsoft Defender Antivirus, or the equivalent for your antivirus product, to cover rapidly evolving attacker tools and techniques.

2024-07-29 14:00:00 | Unc4393 entre doucement dans la nuit silencieuse UNC4393 Goes Gently into the SILENTNIGHT (lien direct) |
Written by: Josh Murchie, Ashley Pearson, Joseph Pisano, Jake Nicastro, Joshua Shilko, Raymond Leong
Overview In mid-2022, Mandiant\'s Managed Defense detected multiple intrusions involving QAKBOT, leading to the deployment of BEACON coupled with other pre-ransomware indicators. This marked Mandiant\'s initial identification of UNC4393, the primary user of BASTA ransomware. Mandiant has responded to over 40 separate UNC4393 intrusions across 20 different industry verticals. While healthcare organizations have not traditionally been a focus for UNC4393, several breaches in the industry this year indicate a possible expansion of their interests. However, this represents only a fraction of the cluster\'s victims, with the Black Basta data leak site purporting over 500 victims since inception. Over the course of this blog post, Mandiant will detail the evolution of UNC4393\'s operational tactics and malware usage throughout its active lifespan, with a focus on the period following the QAKBOT botnet takedown. We will highlight the cluster\'s transition from readily available tools to custom malware development as well as its evolving reliance on access brokers and diversification of initial access techniques. 
Figure 1: UNC4393 intrusion lifecycle
Attribution and Targeting
UNC4393 is a financially motivated threat cluster, and the primary user of BASTA ransomware, tracked since mid-2022 but likely active since early 2022 based on activity on the BASTA DLS. The group has overwhelmingly leveraged initial access gained via UNC2633 and UNC2500 QAKBOT botnet infections to deploy BASTA ransomware. QAKBOT is typically distributed via phishing emails containing malicious links or attachments. In some cases, HTML smuggling has also been used to distribute ZIP files containing IMG files that house LNK files and QAKBOT payloads.
Mandiant suspects BASTA operators maintain a private or small, closed-invitation affiliate model whereby only trusted third-party actors are provided with use of the BASTA encryptor. Unlike traditional ransomware-as-a-service (RaaS), BASTA is not publicly marketed and its operators do not appear to actively recruit affiliates to deploy the ransomware. Instead, they focus on acquiring initial access via partnerships or purchases in underground communities. This deviates from traditional RaaS models, which focus on the ransomware development and related services such as the data leak site (DLS) that are provided to affiliates in exchange for directly distributing the ransomware. While UNC4393 is the only currently active threat cluster deploying BASTA that Mandiant tracks, we cannot rule out the possibility that other, vetted threat actors may also be given access to the encrypter.
The hundreds of BASTA ransomware victims claimed on the DLS appear credible due to UNC4393\'s rapid operational tempo. With a median time to ransom of approximately 42 hours, UNC4393 has demonstrated p |

2024-07-29 10:00:00 | Pourquoi vous avez besoin d'un pare-feu d'application Web en 2024 Why You Need a Web Application Firewall in 2024 (lien direct) |
The content of this post is solely the responsibility of the author. LevelBlue does not adopt or endorse any of the views, positions, or information provided by the author in this article. Over the last decade, web applications have become integral to everyday life. This includes business and personal activities, facilitating everything from banking and transactions to marketing and social networking. This rise in popularity has made web applications a prime target for cybercriminals. According to Verizon’s 2024 Data Breach Investigation Report, nearly 40% of cybersecurity incidents result from web application vulnerabilities. Businesses relying on these applications for everyday operations must implement robust security measures to ensure their app stack is resilient to threats and capable of maintaining uninterrupted service. One of the most effective tools for safeguarding web applications is a web application firewall (WAF), which provides critical protection against a wide range of cyber threats. Most Common Threats to Web App Security Before we dive into how web application firewalls protect our web assets, let’s look at the most pressing security threats facing web applications in 2024. Stolen credentials are top of mind, as millions are available for sale on the dark web. One of the most significant cyberattacks of the year involved compromised credentials from a third-party application in an attack on UnitedHealth, which jeopardized the data of one-third of Americans. Attackers were nested inside the victim’s systems for months before striking, highlighting how important real-time monitoring capabilities are for detecting suspicious behavior. Zero-day exploits are also a common vector attackers have used in recent years to breach web applications. A zero-day vulnerability is unknown to the application vendor or the public at the time it is discovered and exploited by attackers. They can be quite dangerous if they’re not identified and patched quickly. In 2023, there were 97 reported zero-day vulnerabilities, a 50% increase from the year before. Additionally, as web applications increasingly rely on each other to provide maximum functionality to the end user, API-related attacks have also become prevalent. App integrations must be executed correctly with strong authentication and authorization mechanisms. Input validation is also required to prevent injection attacks. Modern WAF Solutions Are Essential to Improving Security A web application firewall is a hardware or software-based solution used to monitor and filter HTTP traffic between a web application and the internet. WAFs provide two essential security features: traffic filtering and real-time monitoring. WAFs use rule-based filters to inspect HTTP requests and responses. These filters detect and block a wide spectrum of attacks, including SQL injection, cross-site scripting (XSS), and cross-site request forgery (CSRF). By analyzing traffic in real time, a WAF solution can identify and mitigate threats as they occur, foiling attacks before | Data Breach Tool Vulnerability Threat | ||

2024-07-26 15:00:23 | Voleur de flammes Flame Stealer (lien direct) |
## Snapshot Analysts at Cyfirma have released a report on the widespread adoption of Flame Stealer, an [information stealer](https://security.microsoft.com/intel-profiles/byExternalId/2296d491ea381b532b24f2575f9418d4b6723c17b8a1f507d20c2140a75d16d6) malware for sale on Discord and Telegram. ## Description Designed to steal Discord tokens, browser cookies, and credentials, this tool has been used by numerous threat actors employing various evasion techniques. Initially advertised as untraceable, Flame Stealer operates mainly on Discord, targeting sensitive data from platforms like Discord, Spotify, Instagram, TikTok, and Roblox. he malware is programmed in C/C++, employs DLL side-loading, and sends stolen data to specified webhooks. Flame Stealer achieves persistence by adding programs to startup folders and using code obfuscation techniques to evade detection. It also gathers extensive system information and can capture clipboard data and webcam footage. The Flame Stealer uses Discord webhooks for data exfiltration and has capabilities to shutdown or reboot the target machine. ## Microsoft Analysis In recent years, Microsoft has tracked the growing risk that infostealers pose to enterprise security. Infostealers are commodity malware used to steal information from a target device and send it to the threat actor. The popularity of this class of malware led to the emergence of an infostealer ecosystem and a new class of threat actors who leveraged these capabilities to conduct their attacks. Often, infostealers are advertised as a malware as a service (MaaS) offering – a business model where the developers lease the infostealer payload to distributers for a fee. Information stealers are versatile and can be distributed in various forms including through phishing email campaigns, malvertising, and trojanized software, games and tools. They can target a range of information like session tokens and cookies, saved passwords, financial information, and credentials for internet-facing systems and applications. Typically, once the user downloads and launches the malicious payload, it establishes command and control (C2) connections with suspicious domains. Once infected, the infostealer attempts to collect and ultimately exfiltrate information from the system including files, browsers, internet-facing devices and applications to the C2 servers. ## Recommendations Microsoft recommends the following mitigations to reduce the impact of this threat. Check the recommendations card for the deployment status of monitored mitigations. - Check your Office 365 email filtering settings to ensure you block spoofed emails, spam, and emails with malware.
