## Instantané
Depuis plus de cinq ans, Sophos a suivi plusieurs groupes basés en Chine ciblant leurs pare-feu grâce à des botnets sophistiqués, des exploits uniques et des logiciels malveillants personnalisés.
## Description
La collaboration avec divers fournisseurs de cybersécurité, les agences gouvernementales et les forces de l'ordre a permis aux Sophos d'attribuer des activités spécifiques à des groupes comme [Volt Typhoon] (https: // Security.Microsoft.com/intel-profiles/8fe93ebfb3a03fb94a92ac80847790f1d6cfa08f57b2bcebfad328a5c3e762cb), APT31 (suivi par Microsoft comme [Violet.Micoft 8039ED98462546859F2AC987E7EC77A6C7DA15D760E7AC0AAF173AC486)), et APT41 (suivi par Microsoft comme [Typhoon en laiton] (https://security.microsoft.com/intel-profiles/f0aaa62bfbaf3739bb92106688e6a00fc05afc0d4158b0e389b4078112d37c6)).Enquêtes récentesPar Sophos X-OPS a révélé que le développement d'exploitation de confiance élevée se produisait à Sichuan, où ces exploits seraient partagés entre des groupes parrainés par l'État avec des objectifs et des capacités variables.
L'analyse met également en évidence l'exploitation de vulnérabilités spécifiques, notamment [CVE-2020-12271] (https://security.microsoft.com/intel-Explorer / CVE / CVE-2020-12271 /), [CVE-2020-15069] (https://security.microsoft.com/intel-explorer/cves/cve-2020-15069/), [CVE-2020-29574] (https://security.microsoft.com/intel-explorer/cves/cve-2020-29574/), [CVE-2022-1040] (https://secuth-2022-3236 /).
Sophos a noté un changement significatif dans les comportements des attaquants, passant de larges attaques bruyantes destinées à établir des boîtes de relais opérationnelles (ORB) à des opérations plus ciblées et furtives ciblant les infrastructures de grande valeur, en particulier dans la région indo-pacifique.Les victimes comprennent des organisations dans les secteurs nucléaire, militaire, télécom et gouvernemental.Les tactiques employées par ces adversaires reflètent une amélioration de la furtivité et de la persistance, notamment l'utilisation de techniques de vie, de classes Java en arrière, de chevaux de Troie uniquement et d'un rootkit complexe nommé Cloud Snooper, qui est remarquable pour ses capacités multiplategiennes.

(Déjà vu) Rekoobe Backdoor découverte dans le répertoire ouvert, ciblant éventuellement les utilisateurs de TradingView Rekoobe Backdoor Discovered in Open Directory, Possibly Targeting TradingView Users (lien direct) |
## Instantané
Une enquête récente a découvert la présence de Rekoobe, une porte dérobée initialement utilisée par APT31, suivie parMicrosoft comme [Violet Typhoon] (https://security.microsoft.com/intel-profiles/978d728039ed98462546859f2ac987e77a6c7da15d760e7ac0aaf173AC486), dans les répertoires ouverts.
## Description
Rekoobe, basé en partie sur Tiny Shell, a évolué avec un chiffrement avancé et des paramètres de commande et de contrôle uniques, ce qui rend la détection difficile.Les chercheurs ont trouvé deux échantillons de rekoobe sur un répertoire ouvert lié à l'adresse IP 27.124.45 \ [. \] 146, révélant des binaires de logiciels malveillants étiquetés selon l'architecture et la date.Ces binaires ont tenté de se connecter avec le serveur d'hébergement via un port spécifique, suivant les modèles observés dans d'autres logiciels malveillants Rekoobe.
Une analyse plus approfondie a identifié plusieurs domaines de sosie imitant le site Web populaire de TradingView, suggérant des efforts de phishing potentiels ciblant la communauté financière.Ces domaines présentent de légères variations typographiques, peut-être pour l'ingénierie sociale ou les attaques de phishing.Bien qu'aucun contenu actif n'ait été observé, le chevauchement de ces domaines avec une activité Rekoobe suggère une campagne coordonnée.
L'enquête a également lié d'autres serveurs dans la même infrastructure basée à Hong Kong à l'aide de clés SSH partagées, renforçant la notion d'une configuration malveillante plus large.De plus, un outil de sécurité, Yakit, connu pour son équipe rouge légitime, a été trouvé sur un serveur, soulevant des questions sur son utilisation dans ce contexte.Collectivement, ces résultats révèlent une opération malveillante potentiellement étendue destinée aux plateformes financières, exigeant un examen minutieux.
## Analyse Microsoft et contexte OSINT supplémentaire
L'acteur Microsoft suit comme [Violet Typhoon] (https://security.microsoft.com/intel-profiles/978d728039ed98462546859f2ac987e7ec77a6c7da15d760e7ac0aaf173ac486). Phoon est connu principalementcibler l'ancien gouvernement et le personnel militaire, les ONG et les groupes de réflexion aux États-Unis.Violet Typhoon se concentre sur l'espionnage.L'acteur est connu pour effectuer une analyse de vulnérabilité pour identifier l'infrastructure Web exposée à Internet, telles que les serveurs Web, la gestion de contenu ou les portails de gestion, puis exploiter ces vulnérabilités pour installer des shells Web.De plus, Violet Typhoon utilise la technique de reconnaissance des bogues Web.
Le typhon Violet a également été observé à l'aide de courriels de phisseur de lance contenant un lien qui redirige vers les pages de connexion de récolte des informations d'identification.Après avoir obtenu un accès initial, le typhon Violet utilise des techniques d'adversaire dans le milieu et des capacités de fenêtres intégrées pour le mouvement latéral et l'escalade des privilèges.Microsoft a également observé le groupe à l'aide d'exploits de jours zéro pour l'escalade des privilèges.Violet Typhoon est suivi par d'autres sociétés de sécurité en tant qu'APT31.

EastWind campaign: new CloudSorcerer attacks on government organizations in Russia (lien direct) |
#### Targeted Geolocations
- Russia
#### Targeted Industries
- Government Agencies & Services
- Information Technology
## Snapshot
Researchers at Kapersky identified a targeted cyberattack campaign, named EastWind, that occurred in late July 2024, targeting Russian government organizations and IT companies.
## Description
The threat actors utilized phishing emails with malicious shortcut attachments to infect devices, delivering malware that received commands via the Dropbox cloud service. The additional payloads included the VERSION.dll backdoor, GrewApacha RAT used by APT31 (tracked by Microsoft as Violet Typhoon) since 2021, a new version of the CloudSorcerer backdoor, and the PlugY implant, which overlaps with APT27 (tracked by Microsoft as Linen Typhoon) tools.
The attackers gained initial access to organizations through spear phishing, sending malicious emails with attached RAR archives containing decoy documents and malicious files. The campaign demonstrated the evolving tactics and techniques employed by threat actors to infiltrate and compromise targeted organizations, emphasizing the ongoing threat of sophisticated cyberattacks targeting government and IT sectors.
## Additional Analysis
Kapersky [previously reported](https://securelist.com/cloudsorcerer-new-apt-cloud-actor/113056/) on the CloudSorcerer backdoor and its use in attacks on government organizations in Russia. Used as a cyberespionage tool, the malware employs public cloud services as its primary command and control (C2) servers. Kaspersky has assessed that CloudSorcerer\'s activities resemble those of the [CloudWizard APT](https://securelist.com/cloudwizard-apt/109722/). However, notable differences in the malware\'s code and functionality suggest that CloudSorcerer is likely a new actor.
## Detections/Hunting Queries
### Microsoft Defender Antivirus
Microsoft Defender Antivirus detects threat components as the following malware:
- [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. 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.

Phishing pour l'or: cyber-menaces auxquelles sont confrontés les Jeux olympiques de Paris 2024 Phishing for Gold: Cyber Threats Facing the 2024 Paris Olympics (lien direct) |
Written by: Michelle Cantos, Jamie Collier
Executive Summary
Mandiant assesses with high confidence that the Paris Olympics faces an elevated risk of cyber threat activity, including cyber espionage, disruptive and destructive operations, financially-motivated activity, hacktivism, and information operations.
Olympics-related cyber threats could realistically impact various targets including event organizers and sponsors, ticketing systems, Paris infrastructure, and athletes and spectators traveling to the event.
Mandiant assesses with high confidence that Russian threat groups pose the highest risk to the Olympics. While China, Iran, and North Korea state sponsored actors also pose a moderate to low risk.
To reduce the risk of cyber threats associated with the Paris Olympics, organizations should update their threat profiles, conduct security awareness training, and consider travel-related cyber risks.
The security community is better prepared for the cyber threats facing the Paris Olympics than it has been for previous Games, thanks to the insights gained from past events. While some entities may face unfamiliar state-sponsored threats, many of the cybercriminal threats will be familiar. While the technical disruption caused by hacktivism and information operations is often temporary, these operations can have an outsized impact during high-profile events with a global audience.
Introduction
The 2024 Summer Olympics taking place in Paris, France between July and August creates opportunities for a range of cyber threat actors to pursue profit, notoriety, and intelligence. For organizations involved in the event, understanding relevant threats is key to developing a resilient security posture. Defenders should prepare against a variety of threats that will likely be interested in targeting the Games for different reasons:
Cyber espionage groups are likely to target the 2024 Olympics for information gathering purposes, due to the volume of government officials and senior decision makers attending.
Disruptive and destructive operations could potentially target the Games to cause negative psychological effects and reputational damage. This type of activity could take the form of website defacements, distributed denial of service (DDoS) attacks, the deployment of wiper malware, and operational technology (OT) targeting. As a high profile, large-scale sporting event with a global audience, the Olympics represents an ideal stage for such operations given that the impact of any disruption would be significantly magnified.
Information operations will likely leverage interest in the Olympics to spread narratives and disinformation to target audiences. In some cases, threat actors may leverage disruptive and destructive attacks to amplify the spread of particular narratives in hybrid operations.
Financially-motivated actors are likely to target the Olympics in v |

Extinction de l'IOC?Les acteurs de cyber-espionnage de Chine-Nexus utilisent des réseaux orbes pour augmenter les coûts des défenseurs IOC Extinction? China-Nexus Cyber Espionage Actors Use ORB Networks to Raise Cost on Defenders (lien direct) |
Written by: Michael Raggi
Mandiant Intelligence is tracking a growing trend among China-nexus cyber espionage operations where advanced persistent threat (APT) actors utilize proxy networks known as “ORB networks” (operational relay box networks) to gain an advantage when conducting espionage operations. ORB networks are akin to botnets and are made up of virtual private servers (VPS), as well as compromised Internet of Things (IoT) devices, smart devices, and routers that are often end of life or unsupported by their manufacturers. Building networks of compromised devices allows ORB network administrators to easily grow the size of their ORB network with little effort and create a constantly evolving mesh network that can be used to conceal espionage operations.
By using these mesh networks to conduct espionage operations, actors can disguise external traffic between command and control (C2) infrastructure and victim environments including vulnerable edge devices that are being exploited via zero-day vulnerabilities.
These networks often use both rented VPS nodes in combination with malware designed to target routers so they can grow the number of devices capable of relaying traffic within compromised networks.
Mandiant assesses with moderate confidence that this is an effort to raise the cost of defending an enterprise\'s network and shift the advantage toward espionage operators by evading detection and complicating attribution. Mandiant believes that if network defenders can shift the current enterprise defense paradigm away from treating adversary infrastructure like indicators of compromise (IOCs) and instead toward tracking ORB networks like evolving entities akin to APT groups, enterprises can contend with the rising challenge of ORB networks in the threat landscape.
IOC Extinction and the Rise of ORB Networks
The cybersecurity industry has reported on the APT practice of ORB network usage in the past as well as on the functional implementation of these networks. Less discussed are the implications of broad ORB network usage by a multitude of China-nexus espionage actors, which has become more common over recent years. The following are three key points and paradigm shifting implications about ORB networks that require enterprise network defenders to adapt the way they think about China-nexus espionage actors:
ORB networks undermine the idea of “Actor-Controlled Infrastructure”: ORB networks are infrastructure networks administered by independent entities, contractors, or administrators within the People\'s Republic of China (PRC). They are not controlled by a single APT actor. ORB networks create a network interface, administer a network of compromised nodes, and contract access to those networks to multiple APT actors that will use the ORB networks to carry out their own distinct espionage and reconnaissance. These networks are not controlled by APT actors using them, but rather are temporarily used by these APT actors often to deploy custom tooling more conventionally attributable to known China-nexus adversaries.

Pole Voûte: cyber-menaces aux élections mondiales Poll Vaulting: Cyber Threats to Global Elections (lien direct) |
Written by: Kelli Vanderlee, Jamie Collier
Executive Summary
The election cybersecurity landscape globally is characterized by a diversity of targets, tactics, and threats. Elections attract threat activity from a variety of threat actors including: state-sponsored actors, cyber criminals, hacktivists, insiders, and information operations as-a-service entities. Mandiant assesses with high confidence that state-sponsored actors pose the most serious cybersecurity risk to elections.
Operations targeting election-related infrastructure can combine cyber intrusion activity, disruptive and destructive capabilities, and information operations, which include elements of public-facing advertisement and amplification of threat activity claims. Successful targeting does not automatically translate to high impact. Many threat actors have struggled to influence or achieve significant effects, despite their best efforts.
When we look across the globe we find that the attack surface of an election involves a wide variety of entities beyond voting machines and voter registries. In fact, our observations of past cycles indicate that cyber operations target the major players involved in campaigning, political parties, news and social media more frequently than actual election infrastructure.
Securing elections requires a comprehensive understanding of many types of threats and tactics, from distributed denial of service (DDoS) to data theft to deepfakes, that are likely to impact elections in 2024. It is vital to understand the variety of relevant threat vectors and how they relate, and to ensure mitigation strategies are in place to address the full scope of potential activity.
Election organizations should consider steps to harden infrastructure against common attacks, and utilize account security tools such as Google\'s Advanced Protection Program to protect high-risk accounts.
Introduction
The 2024 global election cybersecurity landscape is characterized by a diversity of targets, tactics, and threats. An expansive ecosystem of systems, administrators, campaign infrastructure, and public communications venues must be secured against a diverse array of operators and methods. Any election cybersecurity strategy should begin with a survey of the threat landscape to build a more proactive and tailored security posture.
The cybersecurity community must keep pace as more than two billion voters are expected to head to the polls in 2024. With elections in more than an estimated 50 countries, there is an opportunity to dynamically track how threats to democracy evolve. Understanding how threats are targeting one country will enable us to better anticipate and prepare for upcoming elections globally. At the same time, we must also appreciate the unique context of different countries. Election threats to South Africa, India, and the United States will inevitably differ in some regard. In either case, there is an opportunity for us to prepare with the advantage of intelligence.

Phorpiex botnet is back with a new Twizt: Hijacking Hundreds of crypto transactions
(published: December 16, 2021)
Check Point Research has uncovered a new variant of the Phorpiex botnet named Twizt. Historically, Phorpiex utilized sextortion, ransomware delivery, and cryptocurrency clipping. Twizt however, appears to be primarily focused on stealing cryptocurrency and have stolen half a million dollars since November 2020 in the form of Bitcoin, Ether and ERC20 tokens.The botnet features departure from it’s traditional command and control (C2) infrastructure, opting for peer-to-peer (P2P) communications between infected hosts, eliminating the need for C2 communication as each host can fulfill that role.
Analyst Comment: Bots within a P2P network need to communicate regularly with other bots to receive and share commands. If the infected bots are on a private network, private IP addresses will be used. Therefore, careful monitoring of network traffic will reveal suspicious activity, and a spike in network resource usage as opposed to the detection of C2 IP addresses.

Windows “PetitPotam” Network Attack – How to Protect Against It
(published: July 21, 2021)
Microsoft has released mitigations for a new Windows vulnerability called PetitPotam. Security researcher, Gillesl Lionel, created a proof-of-concept script that abuses Microsoft’s NT Lan Manager (NTLM) protocol called MS-EFSRPC (encrypting file system remote protocol). PetitPotam can only work if certain system functions that are enabled if the following conditions are met: NTLM authentication is enabled on domain, active directory certificate services (AD CS) is being used, certificate authority web enrollment or certificate enrollment we service are enabled. Exploitation can result in a NTLM relay attack, which is a type of man-in-the-middle attack.
Analyst Comment: Microsoft has provided mitigation steps to this attack which includes disabling NTLM on a potentially affected domain, in addition to others.

APT31 Modus Operandi Attack Campaign Targeting France
(published: July 21, 2021)
The French cybersecurity watchdog, ANSSII issued an alert via France computer emergency response team (CERT) discussing attacks targeting multiple French entities. The China-sponsored, advanced persistent threat (APT) group APT31 (Judgment Panda, Zirconium) has been attributed to this ongoing activity. The group was observed using “a network of compromised home routers as operational relay boxes in order to perform stealth reconnaissance as well as attacks.”
Analyst Comment: Defense-in-depth (layering of security mechanisms, redundancy, fail-safe defense processes) is the best way to ensure safety from APTs, including a focus on both network and host-based security. Prevention and detection capabilities should also be in place.

UK and Allies Accuse China for a Pervasive Pattern of Hacking, Breaching Microsoft Exchange Servers
(published: July 19, 2021)
On July 19th, 2021, the US, the UK, and other global allies jointly accused China in a pattern of aggressive malicious cyber activity. First, they confirmed that Chinese state-backed actors (previously identified under the group name Hafnium) were responsible for gaining access to computer networks around the world via Microsoft Exchange servers. The attacks took place in early 2021, affecting over a quarter of a million servers worldwide. Additionally, APT31 (Judgement Panda) and APT40 (Kryptonite Panda) were attributed to Chinese Ministry of State Security (MSS), The US Department of Justice (DoJ) has indicted four APT40 members, and the Cybersecurity and Infrastructure Security Agency (CISA) shared indicators of compromise of the historic APT40 activity.
Analyst Comment: Network defense-in-depth and adherence to information security best practices can assist organizations in reducing the risk. Pay special attention to the patch and vulnerability management, protecting credentials, and continuing network hygiene and monitoring. When possible, enforce the principle of least privilege, use segmentation and strict access control measures for critical data. Organisations can use Anomali Match to perform real time forensic analysis for tracking such attacks.

Hypervisor Jackpotting: CARBON SPIDER and SPRITE SPIDER Target ESXi Servers With Ransomware to Maximize Impact
(published: February 26, 2021)
Recent reporting indicates that two prolific cybercrime threat groups, CARBON SPIDER and SPRITE SPIDER, have begun targeting ESXi, a hypervisor developed by VMWare to run and manage virtual machines. SPRITE SPIDER uses PyXie's LaZagne module to recover vCenter credentials stored in web browsers and runs Mimikatz to steal credentials from host memory. After authenticating to vCenter, SPRITE SPIDER enables ssh to permit persistent access to ESXi devices. In some cases, they also change the root account password or the host’s ssh keys. Before deploying Defray 777, SPRITE SPIDER’s ransomware of choice, they terminate running VMs to allow the ransomware to encrypt files associated with those VMs. CARBON SPIDER has traditionally targeted companies operating POS devices, with initial access being gained using low-volume phishing campaigns against this sector. But throughout 2020 they were observed shifting focus to “Big Game Hunting” with the introduction of the Darkside Ransomware. CARBON SPIDER gains access to ESXi servers using valid credentials and reportedly also logs in over ssh using the Plink utility to drop the Darkside
Recommendation: Both CARBON SPIDER and SPRITE SPIDER likely intend to use ransomware targeting ESXi to inflict greater harm – and hopefully realize larger profits – than traditional ransomware operations against Windows systems. Should these campaigns continue and prove to be profitable, we would expect more threat actors to imitate these activities.

China’s ‘Hybrid War’: Beijing’s Mass Surveillance of Australia and the World for Secrets and Scandal
(published: September 14, 2020)
A database containing 2.4 million people has been leaked from a Shenzhen company, Zhenhua Data, believed to have ties to the Chinese intelligence service. The database contains personal information on over 35,000 Australians and prominent figures, and 52,000 Americans. This includes addresses, bank information, birth dates, criminal records, job applications, psychological profiles, and social media. Politicians, lawyers, journalists, military officers, media figures, and Natalie Imbruglia are among the records of Australians contained in the database. While a lot of the information is public, there is also non-public information contributing to claims that China is developing a mass surveillance system.
Recommendation: Users should always remain vigilant about the information they are putting out into the public, and avoid posting personal or sensitive information online.

US Criminal Court Hit by Conti Ransomware; Critical Data at Risk
(published: September 11, 2020)
The Fourth District Court of Louisiana, part of the US criminal court system, appears to have become the latest victim of the Conti ransomware. The court's website was attacked and used to steal numerous court documents related to defendants, jurors, and witnesses, and then install the Conti ransomware. Evidence of the data theft was posted to the dark web. Analysis of the malware by Emsisoft’s threat analyst, Brett Callow, indicates that the ransomware deployed in the attack was Conti, which has code similarity to another ransomware strain, Ryuk. The Conti group, believed to be behind this ransomware as a service, is sophisticated and due to the fact that they receive a large portion of the ransoms paid, they are motivated to avoid detections and continue to develop advanced attacking tools. This attack also used the Trickbot malware in its exploit chain, similar to that used by Ryuk campaigns.
Recommendation: Defense in Depth, including vulnerability remediation and scanning, monitoring, endpoint protection, backups, etc. is key to thwarting increasingly sophisticated attacks. Ransomware attacks are particularly attractive to attackers due to the fact that each successful ransomware attack allows for multiple streams of income. The attackers can not only extort a ransom to decrypt the victim's files (especially in cases where the victim finds they do not have appropriate disaster recovery plans), but they can also monetize the exfiltrated data directly and/or use the data to aid in future attacks. This technique is increasingly used in supply chain compromises to build difficult to detect spearphishing attacks.
