2024-01-09 11:57:12 | L'augmentation préoccupante des attaques centrées sur l'identité: tendances et faits The Concerning Rise in Identity-Centric Attacks: Trends and Facts (lien direct) |
Identity threats are by no means a new type of crime. But in today\'s increasingly digitized world, there are more opportunities for bad actors to steal identities and engage in identity-centric attacks than ever before. Unfortunately, user identities are tough for businesses to protect. The fact that these types of attacks are skyrocketing is evidence of that-in the past year alone the Identity Defined Security Alliance reports that a whopping 84% of companies experienced an identity-related security breach. In this post, we\'ll take a look at identity attack statistics and trends and provide some recent case studies to illustrate how some attacks work. We\'ll also highlight one of the most important identity threat facts-that the human element plays a crucial role in the success of these attacks. Understanding identity-centric attacks There are many types of identity attacks. When most people think of these types of crimes, they often imagine traditional identity theft scenarios: Financial identity theft, where a criminal gains access to a victim\'s financial data, like their credit card details, bank account numbers or Social Security number, to make unauthorized purchases, withdraw funds or open new accounts. Tax identity theft, where a bad actor uses a victim\'s personal information to file false tax returns and claim refunds, diverting the money to their own accounts. Employment identity theft, where a fraudster uses a victim\'s identity to get a job, potentially causing issues for that person when discrepancies arise in their employment and tax records. But identity-based attacks also target enterprises and their online users. The cybercriminals behind these attacks might aim to steal sensitive data, siphon off funds, damage or disrupt systems, deploy ransomware or worse. Those are the types of identity attacks we\'re covering here. Identity threat trends and tactics In short, identity-centric attacks are a practical calculation by bad actors: Why would they invest their time and resources to build exploits to help them get in through a virtual back door when they can just walk through the front door? But before they reap the rewards, they still have some legwork to do. Here are a few techniques that cybercriminals use to progress identity-based attacks against businesses and their users: MFA bypass attacks. Many businesses today use multifactor authentication (MFA) to protect the account of their users. It\'s more secure than using passwords alone. But of course, bad actors have found new ways to bypass commonly used MFA methods. MFA fatigue attacks are one example. People-activated malware. People often give life to malware when they fall for a phishing scam or other social engineering tactics. Malware can appear in the form of a .zip file, QR code, .html link, MS Office file and more-there are at least 60 known techniques to plant people-activated malware on corporate networks. Active Directory (AD) attacks. Most enterprises today use AD as a primary method for directory services like user authentication and authorization. Cybercriminals are keen to target AD, which touches almost every place, person and device on a network. This approach works very well, too-more than half of identity-related breaches can be traced back to AD. Cached credentials harvesting. Cached credentials are commonly stored on endpoints, in memory, in the registry, in a browser or on disk. Attackers use various tools and techniques to collect these credentials and gain access to more privileged identities. Once they have harvested these credentials, they can use them to move laterally and log into different applications. Adversaries are likely to find a good “crop” when they are harvesting cached credentials. Recent research from Proofpoint found that more than one in 10 endpoints have exposed privileged account passwords, making it one of the most common identity risks. Keep in mind that cybercriminals are always innovating, and they are quick to build or adopt tools that | Ransomware Malware Tool Threat Studies | Uber | ★★ |

2023-11-27 09:26:51 | 8 sujets essentiels de cybersécurité à inclure dans votre programme de formation 8 Essential Cybersecurity Topics to Include in Your Training Program (lien direct) |
Your employees have a critical role to play as a first line of defense against cyberthreats. But to be effective, they need to know what those threats are-and stay apprised of how they\'re evolving. A comprehensive security awareness program is the key to helping your users grow their understanding of attackers\' methods and objectives so they can become more proactive defenders. That includes knowing what strategies malicious actors employ to manipulate people so they can use them to enable their campaigns. The importance of security awareness It\'s well worth taking the time to craft a meaningful and engaging security awareness program. By presenting the right mix of information to your users in a compelling way, you can empower them to help you improve your organization\'s security posture as well as create a more robust security culture overall. The cybersecurity topics that you include in your program should be relevant to your business and industry, of course. Companies face different cyberthreat challenges and regulatory compliance requirements related to data protection and data privacy. That said, there are several subjects that almost any modern business, regardless of its industry, will want to ensure its employees understand. We list eight of these cybersecurity topics below. They are the go-to approaches and tools that attackers around the world commonly use to compromise users and their accounts, disrupt normal business operations, steal money or data, and do other damage. Here\'s a high-level overview of these eight must-know cybersecurity topics: 1. Social engineering Social engineering is a collection of techniques malicious actors use to manipulate human psychology. Attackers rely on these strategies to trick or threaten users to take actions such as giving up account credentials, handing over sensitive data, running malicious code and transferring funds. They do this by taking advantage of users\': Emotions, by conveying a sense of urgency, generating excitement about an opportunity, or creating fear around losing money or doing something wrong Trust, by posing as someone familiar to the user or a trusted brand or authority-such as the Internal Revenue Service (IRS), UPS, Amazon or Microsoft Fatigue, by timing attacks when users are likely to be tired or distracted and more inclined to let their “emotional mind” guide their decision-making Common social engineering tactics include phishing-which we cover in the next section-and these others: Social media reconnaissance. Attackers often turn to social media to gather information about users that they target with their campaigns. These efforts can include direct outreach to users. Vishing (voice phishing) and smishing (SMS/text phishing). Vishing is the fraudulent practice of making phone calls or leaving voice messages purporting to be from a trusted brand or authority. With smishing, attackers use text messages to send SMS messages to users or robocall them. The messages often promise gifts or services in exchange for payment. Telephone-oriented attack delivery (TOAD). TOAD attacks start with an email that claims to be from a legitimate source and includes a phone number for customer assistance. Callers are connected to fake customer service representatives who then direct the victim through the attack. They may instruct the victim to let them access their machine remotely or download a file that turns out to be malware. Or they might direct them to a phishing site. Common sense can go a long way toward preventing a social engineering attack. Make sure to reiterate that if a message seems too good to be true, it\'s very likely a scam. And if something doesn\'t look or sound right, it probably isn\'t. 2. Phishing Phishing is an example of social engineering. Most phishing messages are sent by email. But some attackers deliver these messages through other methods, including smishing and vishing. Here are some typical strategies: Malicious links.

2023-11-21 08:35:02 | Prévenir les attaques de fatigue du MFA: sauvegarder votre organisation Preventing MFA Fatigue Attacks: Safeguarding Your Organization (lien direct) |
Gaining access to critical systems and stealing sensitive data are top objectives for most cybercriminals. Social engineering and phishing are powerful tools to help them achieve both. That\'s why multifactor authentication (MFA) has become such an important security measure for businesses and users. Without MFA as part of the user authentication process, it is much less challenging for an attacker with stolen credentials to authenticate a user\'s account. The primary goal of MFA is to reduce the risk of unauthorized access, especially in situations where passwords alone may not provide enough protection. Even if an attacker steals a user\'s password, with MFA they still need the second factor (and maybe others) to gain access to an account. Examples of MFA factors include biometrics, like fingerprints, and signals from user devices, like GPS location. MFA isn\'t a perfect solution, though-it can be bypassed. Adversaries are relentless in their efforts to undermine any security defenses standing in the way of their success. (The evolution of phish kits for stealing MFA tokens is evidence of that.) But sometimes, attackers will choose to take an in-your-face approach that is not very creative or technical. MFA fatigue attacks fall into that category. What are MFA fatigue attacks-and how do they work? MFA fatigue attacks, also known as MFA bombing or MFA spamming, are a form of social engineering. They are designed to wear down a user\'s patience so that they will accept an MFA request out of frustration or annoyance-and thus enable an attacker to access their account or device. Many people encounter MFA requests daily, or even multiple times per day, as they sign-in to various apps, sites, systems and platforms. Receiving MFA requests via email, phone or other devices as part of that process is a routine occurrence. So, it is logical for a user to assume that if they receive a push notification from an account that they know requires MFA, it is a legitimate request. And if they are very busy at the time that they receive several push notifications in quick succession to authenticate an account, they may be even more inclined to accept a request without scrutinizing it. Here\'s an overview of how an MFA attack works: A malicious actor obtains the username and password of their target. They can achieve this in various ways, from password-cracking tactics like brute-force attacks to targeted phishing attacks to purchasing stolen credentials on the dark web. The attacker then starts to send MFA notifications to the user continuously, usually via automation, until that individual feels overwhelmed and approves the login attempt just to make the requests stop. (Usually, the push notifications from MFA solutions require the user to simply click a “yes” button to authenticate from the registered device or email account.) Once the attacker has unauthorized access to the account, they can steal sensitive data, install malware and do other mischief, including impersonating the user they have compromised-taking their actions as far as they can or want to go. 3 examples of successful MFA fatigue attacks To help your users understand the risk of these attacks, you may want to include some real-world examples in your security awareness program on this topic. Here are three notable incidents, which are all associated with the same threat actor: Uber. In September 2022, Uber reported that an attacker affiliated with the threat actor group Lapsus$ had compromised a contractor\'s account. The attacker may have purchased corporate account credentials on the dark web, Uber said in a security update. The contractor received several MFA notifications as the attacker tried to access the account-and eventually accepted one. After the attacker logged in to the account, they proceeded to access other accounts, achieving privilege escalation. One action the attacker took was to reconfigure Uber\'s OpenDNS to display a graphic image on some of the company\'s internal sites. Cisco.

2023-10-26 10:00:00 | Ensuring robust security of a containerized environment (lien direct) | The content of this post is solely the responsibility of the author. AT&T does not adopt or endorse any of the views, positions, or information provided by the author in this article. In today’s rapidly evolving digital landscape, containerized microservices have become the lifeblood of application development and deployment. Resembling miniature virtual machines, these entities enable efficient code execution in any environment, be it an on-premises server, a public cloud, or even a laptop. This paradigm eliminates the criteria of platform compatibility and library dependency from the DevOps equation. As organizations embrace the benefits of scalability and flexibility offered by containerization, they must also take up the security challenges intrinsic to this software architecture approach. This article highlights key threats to container infrastructure, provides insights into relevant security strategies, and emphasizes the shared responsibility of safeguarding containerized applications within a company. Understanding the importance of containers for cloud-native applications Containers play a pivotal role in streamlining and accelerating the development process. Serving as the building blocks of cloud-native applications, they are deeply intertwined with four pillars of software engineering: the DevOps paradigm, CI/CD pipeline, microservice architecture, and frictionless integration with orchestration tools. Orchestration tools form the backbone of container ecosystems, providing vital functionalities such as load balancing, fault tolerance, centralized management, and seamless system scaling. Orchestration can be realized through diverse approaches, including cloud provider services, self-deployed Kubernetes clusters, container management systems tailored for developers, and container management systems prioritizing user-friendliness. The container threat landscape According to recent findings of Sysdig, a company specializing in cloud security, a whopping 87% of container images have high-impact or critical vulnerabilities. While 85% of these flaws have a fix available, they can’t be exploited because the hosting containers aren’t in use. That said, many organizations run into difficulties prioritizing the patches. Rather than harden the protections of the 15% of entities exposed at runtime, security teams waste their time and resources on loopholes that pose no risk. One way or another, addressing these vulnerabilities requires the fortification of the underlying infrastructure. Apart from configuring orchestration systems properly, it’s crucial to establish a well-thought-out set of access permissions for Docker nodes or Kubernetes. Additionally, the security of containers hinges on the integrity of the images used for their construction. Guarding containers throughout the product life cycle A container\'s journey encompasses three principal stages. The initial phase involves constructing the container and subjecting it to comprehensive functional and load tests. Subsequently, the container is stored in the image registry, awaiting its moment of execution. The third stage, container runtime, occurs when the container is launched and operates as intended. Early identification of vulnerabilities is vital, and this is where the shift-left security principle plays a role. It encourages an intensified focus on security from the nascent stages of the product life cycle, encompassing the design and requirements gathering phases. By incorporating automated security checks within the CI/CD pipeline, developers can detect security issues early and minimize the chance of security gap | Tool Vulnerability Threat Cloud | Uber | ★★★ |

Cilium is a networking, observability, and security solution with an eBPF-based dataplane. An attacker with the ability to create or modify CiliumNetworkPolicy objects in a particular namespace is able to affect traffic on an entire Cilium cluster, potentially bypassing policy enforcement in other namespaces. By using a crafted `endpointSelector` that uses the `DoesNotExist` operator on the `reserved:init` label, the attacker can create policies that bypass namespace restrictions and affect the entire Cilium cluster. This includes potentially allowing or denying all traffic. This attack requires API server access, as described in the Kubernetes API Server Attacker section of the Cilium Threat Model. This issue has been resolved in Cilium versions 1.14.2, 1.13.7, and 1.12.14.

Cilium is a networking, observability, and security solution with an eBPF-based dataplane. An attacker with the ability to update pod labels can cause Cilium to apply incorrect network policies. This issue arises due to the fact that on pod update, Cilium incorrectly uses user-provided pod labels to select the policies which apply to the workload in question. This can affect Cilium network policies that use the namespace, service account or cluster constructs to restrict traffic, Cilium clusterwide network policies that use Cilium namespace labels to select the Pod and Kubernetes network policies. Non-existent construct names can be provided, which bypass all network policies applicable to the construct. For example, providing a pod with a non-existent namespace as the value of the `io.kubernetes.pod.namespace` label results in none of the namespaced CiliumNetworkPolicies applying to the pod in question.

2023-08-15 10:00:00 | Pourquoi la sécurité de l'API est-elle la prochaine grande chose en cybersécurité? Why is API security the next big thing in Cybersecurity? (lien direct) |
The content of this post is solely the responsibility of the author. AT&T does not adopt or endorse any of the views, positions, or information provided by the author in this article. APIs, formally known as application programming interfaces, occupy a significant position in modern software development. They revolutionized how web applications work by facilitating applications, containers, and microservices to exchange data and information smoothly. Developers can link APIs with multiple software or other internal systems that help businesses to interact with their clients and make informed decisions. Despite the countless benefits, hackers can exploit vulnerabilities within the APIs to gain unauthorized access to sensitive data resulting in data breaches, financial losses, and reputational damage. Therefore, businesses need to understand the API security threat landscape and look out for the best ways to mitigate them. The urgent need to enhance API security APIs enable data exchanges among applications and systems and help in the seamless execution of complex tasks. But as the average number of APIs rises, organizations often overlook their vulnerabilities, making them a prime target of hackers. The State of API Security Q1 Report 2023 survey finding concluded that the attacks targeting APIs had increased 400% during the past six months. Security vulnerabilities within APIs compromise critical systems, resulting in unauthorized access and data breaches like Twitter and Optus API breaches. Cybercriminals can exploit the vulnerabilities and launch various attacks like authentication attacks, distributed denial-of-service attacks (DDoS), and malware attacks. API security has emerged as a significant business issue as another report reveals that by 2023, API abuses will be the most frequent attack vector causing data breaches, and also, 50% of data theft incidents will happen due to insecure APIs. As a result, API security has. become a top priority for organizations to safeguard their data, which may cost businesses $75 billion annually. Why does API security still pose a threat in 2023? Securing APIs has always been a daunting task for most organizations, mainly because of the misconfigurations within APIs and the rise in cloud data breaches. As the security landscape evolved, API sprawl became the top reason that posed a threat to API security. API sprawl is the uncontrolled proliferation of APIs across an organization and is a common problem for enterprises with multiple applications, services, and development teams. As more APIs are created, they expanded the attack surface and emerged as an attractive target for hackers. The issue is that the APIs are not always designed by keeping security standards in mind. This leads to a lack of authorization and authentication, exposing sensitive data like personally identifiable information (PII) or other business data.

[The Mind\'s Bias] Pretexting Now Tops Phishing in Social Engineering Attacks
The New Verizon DBIR is a treasure trove of data. As we will cover a bit below, Verizon reported that 74% of data breaches Involve the "Human Element," so people are one of the most common factors contributing to successful data breaches. Let\'s drill down a bit more in the social engineering section.
They explained: "Now, who has received an email or a direct message on social media from a friend or family member who desperately needs money? Probably fewer of you. This is social engineering (pretexting specifically) and it takes more skill.
"The most convincing social engineers can get into your head and convince you that someone you love is in danger. They use information they have learned about you and your loved ones to trick you into believing the message is truly from someone you know, and they use this invented scenario to play on your emotions and create a sense of urgency. The DBIR Figure 35 shows that Pretexting is now more prevalent than Phishing in Social Engineering incidents. However, when we look at confirmed breaches, Phishing is still on top."
A social attack known as BEC, or business email compromise, can be quite intricate. In this type of attack, the perpetrator uses existing email communications and information to deceive the recipient into carrying out a seemingly ordinary task, like changing a vendor\'s bank account details. But what makes this attack dangerous is that the new bank account provided belongs to the attacker. As a result, any payments the recipient makes to that account will simply disappear.
BEC Attacks Have Nearly Doubled
It can be difficult to spot these attacks as the attackers do a lot of preparation beforehand. They may create a domain doppelganger that looks almost identical to the real one and modify the signature block to show their own number instead of the legitimate vendor.
Attackers can make many subtle changes to trick their targets, especially if they are receiving many similar legitimate requests. This could be one reason why BEC attacks have nearly doubled across the DBIR entire incident dataset, as shown in Figure 36, and now make up over 50% of incidents in this category.
Financially Motivated External Attackers Double Down on Social Engineering
Timely detection and response is crucial when dealing with social engineering attacks, as well as most other attacks. Figure 38 shows a steady increase in the median cost of BECs since 2018, now averaging around $50,000, emphasizing the significance of quick detection.

[Eye on Fraud] A Closer Look at the Massive 72% Spike in Financial Phishing Attacks
With attackers knowing financial fraud-based phishing attacks are best suited for the one industry where the money is, this massive spike in attacks should both surprise you and not surprise you at all.
When you want tires, where do you go? Right – to the tire store. Shoes? Yup – shoe store. The most money you can scam from a single attack? That\'s right – the financial services industry, at least according to cybersecurity vendor Armorblox\'s 2023 Email Security Threat Report.
According to the report, the financial services industry as a target has increased by 72% over 2022 and was the single largest target of financial fraud attacks, representing 49% of all such attacks. When breaking down the specific types of financial fraud, it doesn\'t get any better for the financial industry:
51% of invoice fraud attacks targeted the financial services industry
42% were payroll fraud attacks
63% were payment fraud
To make matters worse, nearly one-quarter (22%) of financial fraud attacks successfully bypassed native email security controls, according to Armorblox. That means one in five email-based attacks made it all the way to the Inbox.
The next layer in your defense should be a user that\'s properly educated using security awareness training to easily identify financial fraud and other phishing-based threats, stopping them before they do actual damage.

2023-05-30 22:00:00 | Rat Seroxen à vendre SeroXen RAT for sale (lien direct) |
This blog was jointly written with Alejandro Prada and Ofer Caspi.
Executive summary
SeroXen is a new Remote Access Trojan (RAT) that showed up in late 2022 and is becoming more popular in 2023. Advertised as a legitimate tool that gives access to your computers undetected, it is being sold for only $30 for a monthly license or $60 for a lifetime bundle, making it accessible.
Key takeaways:
SeroXen is a fileless RAT, performing well at evading detections on static and dynamic analysis.
The malware combines several open-source projects to improve its capabilities. It is a combination of Quasar RAT, r77-rootkit and the command line NirCmd.
Hundreds of samples have shown up since its creation, being most popular in the gaming community. It is only a matter of time before it is used to target companies instead of individual users.
Analysis
Quasar RAT is a legitimate open-source remote administration tool. It is offered on github page to provide user support or employee monitoring. It has been historically associated with malicious activity performed by threat actors, APT groups (like in this Mandiant report from 2017), or government attacks (in this report by Unit42 in 2017).
It was first released in July 2014 as “xRAT” and renamed to “Quasar” in August 2015. Since then, there have been released updates to the code until v1.4.1 in March 2023, which is the most current version. As an open-source RAT tool with updates 9 years after its creation, it is no surprise that it continues to be a common tool used by itself or combined with other payloads by threat actors up to this day.
In a review of the most recent samples, a new Quasar variant was observed by Alien Labs in the wild: SeroXen. This new RAT is a modified branch of the open-source version, adding some modifications features to the original RAT. They’re selling it for monthly or lifetime fee. Figure 1 contains some of the features advertised on their website.
Figure 1. SeroXen features announced on its website.
This new RAT first showed up on a Twitter account, established in September 2022. The person advertising the RAT appeared to be an English-speaking teenager. The same Twitter handle published a review of the RAT on YouTube. The video approached the review from an attacking/Red Team point of view, encouraging people to buy the tool because it is worth the money. They were claiming to be a reseller of the tool.
In December 2022, a specific domain was registered to market/sell the tool, seroxen[.]com. The RAT was distributed via a monthly license for $30 USD or a lifetime license of $60 USD. It was around that time that the malware was first observed in the wild, appearing with 0 detections on VirusTotal.
After a few months, on the 1st of February, the YouTuber CyberSec Zaado published a video alerting the community about the capabilities of the RAT from a defensive perspective. In late February, the RAT was advertised on social media platforms such as TikTok, Twitter, YouTube, and several cracking forums, including hackforums.

First-Ever Attack Leveraging Kubernetes RBAC to Backdoor Clusters
(published: April 21, 2023)
A new Monero cryptocurrency-mining campaign is the first recorded case of gaining persistence via Kubernetes (K8s) Role-Based Access Control (RBAC), according to Aquasec researchers. The recorded honeypot attack started with exploiting a misconfigured API server. The attackers preceded by gathering information about the cluster, checking if their cluster was already deployed, and deleting some existing deployments. They used RBAC to gain persistence by creating a new ClusterRole and a new ClusterRole binding. The attackers then created a DaemonSet to use a single API request to target all nodes for deployment. The deployed malicious image from the public registry Docker Hub was named to impersonate a legitimate account and a popular legitimate image. It has been pulled 14,399 times and 60 exposed K8s clusters have been found with signs of exploitation by this campaign.
Analyst Comment: Your company should have protocols in place to ensure that all cluster management and cloud storage systems are properly configured and patched. K8s buckets are too often misconfigured and threat actors realize there is potential for malicious activity. A defense-in-depth (layering of security mechanisms, redundancy, fail-safe defense processes) approach is a good mitigation step to help prevent actors from highly-active threat groups.

2022-10-18 08:41:18 | The benefits of taking an intent-based approach to detecting Business Email Compromise (lien direct) |  By Abhishek Singh.BEC is a multi-stage attack. Adversaries first identify targets, then they establish rapport with the victim before exploiting them for whatever their end goal is. In the case of BEC, a threat actor can impersonate any employee in the organization to trick targets. A policy that checks for authorized email addresses of the sender can prevent BEC attacks. However, scaling the approach for every employee in a large organization is a challenge. Building an executive profile based on email analysis using a machine learning model and scanning emails against that profile will detect BEC. Data collection for building and training machine learning algorithms can take time, though, opening a window of opportunity for threat actors to exploit. Detection of exploitation techniques such as lookalike domains and any differences in the email addresses in the "From" and "Reply-to" fields can also detect BEC messages. However, the final verdict cannot account for the threat actor's intent. The intent-based approach detects BEC and then classifies it into the type of scam. It catches BEC messages, irrespective of whether a threat actor is impersonating a C-level executive or any employee in an organization. Classification based on the type of scam can help identify which segment of an organization was targeted and which employees were being impersonated by the threat actor. The additional information will further assist in better designing preventive features to stop BEC. Business email compromise (BEC) is one of the most financially damaging online crimes. As per the internet crime 221 report, the total loss in 2021 due to BEC is around 2.4 billion dollars. Since 2013, BEC has resulted in a 43 billion dollars loss. The report defines BEC as a scam targeting businesses (not individuals) working with foreign suppliers and companies regularly performing wire transfer payments. Fraudsters carry out these sophisticated scams to conduct the unauthorized transfer of funds. This introduces the challenge of how to detect and block these campaigns as they continue to compromise organizations successfully. There are a variety of approaches to identifying BEC email messages, such as using policy to allow emails from authorized email addresses, detecting exploitation techniques used by threat actors, building profiles by analysis of emails, and validating against the profile to detect BEC. These approaches have a variety of limitations or shortcomings. Cisco Talos is taking a different approach and using an intent-based model to identify and block BEC messages. Before we get too deep into the intent-based model, take a deeper look at the commonly used approaches to block BEC from the simplistic through machine learning (ML) approaches. Policy-based detection The first place to start is with policy-based detection as it is one of the most common and simplistic approaches to blocking BEC campaigns. Let's start by looking at an example of a BEC email. |

2022-10-13 10:00:00 | The biggest concerns within the US Financial Sector in 2022 (lien direct) | This blog was written by an independent guest blogger. The value of digital payment transactions is growing as the world's payment environment moves more and more away from cash. Over the past few years, BFSI (Banking, Financial Service, and Insurance) firms have continued to be a top target for hackers. In fact, the Sixth Annual Bank Survey found that more than 70% of fintech companies named information security as their top issue. According to VMware's Modern Bank Heists study, since the COVID-19 epidemic, there have been 238% more cyberattacks on companies in the financial sector. Artificial intelligence (AI) and self-learning malware are making cyberattacks more sophisticated. While ransomware assaults are the most profitable for cybercriminals, phishing attacks prey on unsuspecting and defenseless consumers. Thus, it should come as no surprise that 39% of financial industry executives think that the overall network security threat to BFSI sector companies has increased significantly. Financial and banking firms in the US must put cybersecurity first above all else given the volume of sensitive data that the BFSI sector must manage. Leading analytics company GlobalData predicts that rising demand for cybersecurity would cause worldwide security revenues in the retail banking industry to climb from $7.9 billion in 2019 to $9.8 billion in 2024. What are the biggest concerns facing the financial sector in the United States for 2022? Reimbursing cyber scams As banks are under pressure to compensate their scammed consumers, rising cybercrime rates translate to rising costs for the industry. More than half (58%) of those who conduct their banking online encounter scams via email or SMS at least once per week, and 23% report having fallen victim to a cyberattack. Banks currently reimburse authorized push payment (APP) fraud at an average rate of 46%. Although many banking institutions are refusing reimbursements for online fraud, this is due to change soon, or else the situation will backfire. For example, measures supported by the UK government will require banks to reimburse everyone. This is only one illustration of the fact that if banks are to secure their consumers and their business line in 2022, they must prioritize cybersecurity more highly. To exchange efficient strategies, banks will need to collaborate with governments and industry organizations. The public must continue to get education on preventative measures, but ultimately it is the banks' responsibility to establish security models that will give them and their clients the greatest level of safety. Maintain compliance with strict privacy regulations The use of social engineering and account takeover fraud will increase over the next years. Financial institutions must not only conduct comprehensive data checks beyond document verification at account opening to fight this but also keep track of customer identities throughout the customer lifecycle.

Hacker Pwns Uber Via Compromised VPN Account
(published: September 16, 2022)
On September 15, 2022, ride-sharing giant Uber started an incident response after discovering a data breach. According to Group-IB researchers, download file name artifacts point to the attacker getting access to fresh keylogger logs affecting two Uber employees from Indonesia and Brazil that have been infected with Racoon and Vidar stealers. The attacker allegedly used a compromised VPN account credentials and performed multifactor authentication fatigue attack by requesting the MFA push notification many times and then making a social-engineering call to the affected employee. Once inside, the attacker allegedly found valid credentials for privilege escalation: a PowerShell script containing hardcoded credentials for a Thycotic privileged access management admin account. On September 18, 2022, Rockstar Games’ Grand Theft Auto 6 suffered a confirmed data leak, likely caused by the same attacker.
Analyst Comment: Network defenders can consider setting up alerts for signs of an MFA fatigue attack such as a large number of MFA requests in a relatively short period of time. Review your source code for embedded credentials, especially those with administrative privileges.

2022-08-18 08:00:00 | Ukraine and the fragility of agriculture security (lien direct) |  By Joe Marshall.The war in Ukraine has had far-reaching global implications and one of the most immediate effects felt will be on the global supply chain for food. This war-induced fragility has exposed the weaknesses of how we feed ourselves globally. Ransomware cartels and other adversaries are well aware of this and are actively exploiting that fragility. For the past six years, Cisco Talos has been actively involved in assisting public and private institutions in Ukraine to defend themselves against state-sponsored actors. Our involvement stretches the gamut from commercial to critical infrastructure, to election security. Our presence has afforded us unique opportunities and observations about cybersecurity in a macro and micro way. Ukraine has been a frequent victim of state-sponsored cyber attacks aimed at critical infrastructures like power and transportation. Talos is proud to stand with our partners in Ukraine and help defend their critical networks and help users there maintain access to necessary services. Now that Russia has invaded Ukraine, those threats have escalated to kinetic attacks that are wreaking havoc on a critical element of our world: agriculture and our global food supply chain. Even worse is the implications this war will have for future cyber attacks, as fragility is considered a lucrative element in deciding victimology by threat actors like ransomware cartels. To truly grasp the implications of the war in Ukraine, we have to examine how vital Ukrainian agriculture feeds the world, the current state of affairs, and what this means for the global cybersecurity posture to protect agricultural assets. Where there is weakness, there is opportunityRansomware cartels and their affiliates are actively targeting the agricultural industry. Moreover, these actors have done their homework and are targeting agricultural companies during the two times of the year where they cannot suffer disruptions: planting and harvesting. Per the published FBI PIN Alert: “Cyber actors may perceive cooperatives as lucrative targets with a willingness to pay due to the time-sensitive role they play in agricultural production.” This is far from unusual for these adversaries - they are shrewd and calculating, and understand their victims' weaknesses and industries.

2022-08-10 10:00:00 | Are cloud containers a sugar-coated threat? (lien direct) | This blog was written by an independent guest blogger. Containerization is a rapidly evolving technology in cloud-native applications. Just like computing systems, containers consist of packages of software programs with all the vital elements like binaries, files, and libraries for running an application in the environment from anywhere. Containers are lightweight, and DevOps teams develop applications and deploy services using them. Moreover, organizations also use these containers to deploy and scale the DevOps infrastructure like the CI/CD tools. A report reveals that by 2022, organizations are likely to run 24% of their workload on containers. However, despite the benefits containers offer, it doesn’t mean they are completely secure. A study revealed that 87% of organizations had deployed containers in their production, while it's found that 94% had experienced at least one security incident. Another research finds that 45% of organizations have delayed or slowed down their application deployment process because of container security issues. All these issues can cause organizations to slow down their transformation journey and bear financial and reputational loss. To avoid such circumstances, organizations need to be aware of cloud container threats and learn how to minimize risks. Why are cloud containers becoming a growing threat? Containerization is a fast-moving trend that plays a pivotal role in improving agility and boosting innovation and is necessary for application development. The adoption of containers has soared in recent years and will continue to rise - and why not, as it transforms how an organization deploys IT infrastructure. Gartner predicts that by 2023, 70% of organizations will use containerized applications. In a survey, the Cloud-Native Computing Foundation (CFNC) finds that 96% of enterprises have evaluated or actively use Kubernetes. Besides this, 68% of the IT leaders in the Red Hat State of Enterprise Open Source Report for 2022 say that container technology is on the level of other important technologies, like Artificial Intelligence and Machine Learning. Container adoption comes with great advantages, but can also pose cybersecurity threats and challenges that adversely impact organizations. Enterprises who depend on container technology but fail to identify the security vulnerabilities and implement mitigation measures compromise their sensitive business data, including customer data. The situation becomes even more dire since most of these threats can’t be mitigated through endpoint security tools such as proxies or VPNs. Here are some of the reasons cloud containers are becoming a threat to organizations: Human error Hackers can compromise container technology in the cloud in several ways. | Malware Vulnerability Threat Guideline | Uber | |

To use a privileged pod as a “trampoline” in GKE, there is a major prerequisite – the attacker has to first execute a successful application compromise and container breakout attack. Because the use of privileged pods in an attack requires a first step such as a container breakout to be effective, let's look at two areas:features of GKE you can use to reduce the likelihood of a container breakoutsteps the GKE team is taking to minimize the use of privileged pods and the privileges needed in them.Reducing container breakoutsThere are a number of features in GKE along with some best practices that you can use to reduce the likelihood of a container breakout:Use GKE Sandbox to strengthen the container security boundary. Over the last few months, GKE Sandbox has protected containers running it against several newly discovered Linux kernel breakout CVEs.Adopt GKE Autopilot for new clusters. Autopilot clusters have default policies that prevent host access through mechanisms like host path volumes and host network. The container runtime default seccomp profile is also enabled by default on Autopilot which has prevented several breakouts.Subscribe to GKE Release Channels and use autoupgrade to keep nodes patched automatically against kernel vulnerabilities.Run Google's Container Optimized OS, the minimal and hardened container optimized OS that makes much of the disk read-only.Incorporate binary authorization into your SDLC to require that containers admitted into the cluster are from trusted build systems and up-to-date on patching.Use Secure Command Center's Container Threat Detection or supported third-party tools to detect the most common runtime attacks.More information can be found in the GKE Hardening Guide.How GKE is reducing the use of privileged pod | Tool Threat | Uber | |

SocGholish and Zloader – From Fake Updates and Installers to Owning Your Systems
(published: April 25, 2022)
Cybereason researchers have compared trending attacks involving SocGholish and Zloader malware. Both infection chains begin with social engineering and malicious downloads masquerading as legitimate software, and both lead to data theft and possible ransomware installation. SocGholish attacks rely on drive-by downloads followed by user execution of purported browser installer or browser update. The SocGholish JavaScript payload is obfuscated using random variable names and string manipulation. The attacker domain names are written in reverse order with the individual string characters being put at the odd index positions. Zloader infection starts by masquerading as a popular application such as TeamViewer. Zloader acts as information stealer, backdoor, and downloader. Active since 2016, Zloader actively evolves and has acquired detection evasion capabilities, such as excluding its processes from Windows Defender and using living-off-the-land (LotL) executables.
Analyst Comment: All applications should be carefully researched prior to installing on a personal or work machine. Applications that request additional permissions upon installation should be carefully vetted prior to allowing permissions. Additionally, all applications, especially free versions, should only be downloaded from trusted vendors.

A recent discovery has been made that links malicious VBA macro code between multiple groups, namely: Transparent Tribe, Donot Team, SideCopy, Operation Hangover, and SideWinder. These groups operate (or operated) out of South Asia and use a variety of techniques with phishing emails and maldocs to target government and military entities within India and Pakistan. The code is similar enough that it suggests cooperation between APT groups, despite having completely different goals/targets.
Analyst Comment: This research shows that APT groups are sharing TTPs to assist each other, regardless of motive or target. Files that request content be enabled to properly view the document are often signs of a phishing attack. If such a file is sent to you via a known and trusted sender, that individual should be contacted to verify the authenticity of the attachment prior to opening. Thus, any such file attachment sent by unknown senders should be viewed with the utmost scrutiny, and the attachments should be avoided and properly reported to appropriate personnel.

Fake Windows 11 Upgrade Installers Infect You With RedLine Malware
(published: February 9, 2022)
Due to the recent announcement of Windows 11 upgrade availability, an unknown threat actor has registered a domain to trick users into downloading an installer that contains RedLine malware. The site, "windows-upgraded[.]com", is a direct copy of a legitimate Microsoft upgrade portal. Clicking the 'Upgrade Now' button downloads a 734MB ZIP file which contains an excess of dead code; more than likely this is to increase the filesize for bypassing any antivirus scan. RedLine is a well-known infostealer, capable of taking screenshots, using C2 communications, keylogging and more.
Analyst Comment: Any official Windows update or installation files will be downloaded through the operating system directly. If offline updates are necessary, only go through Microsoft sites and subdomains. Never update Windows from a third-party site due to this type of attack.

2021-10-06 19:06:00 | Inside TeamTNT\'s Impressive Arsenal: A Look Into A TeamTNT Server (lien direct) | Authored By: Tara Gould
Key Findings
Anomali Threat Research has discovered an open server to a directory listing that we attribute with high confidence to the German-speaking threat group, TeamTNT.
The server contains source code, scripts, binaries, and cryptominers targeting Cloud environments.
Other server contents include Amazon Web Services (AWS) Credentials stolen from TeamTNT stealers are also hosted on the server.
This inside view of TeamTNT infrastructure and tools in use can help security operations teams to improve detection capabilities for related attacks, whether coming directly from TeamTNT or other cybercrime groups leveraging their tools.
Overview
Anomali Threat Research has identified a TeamTNT server open to directory listing. The server was used to serve scripts and binaries that TeamTNT use in their attacks, and also for the IRC communications for their bot. The directory appears to have been in use since at least August 2021 and was in use as of October 5, 2021. The contents of the directory contain metadata, scripts, source code, and stolen credentials.
TeamTNT is a German-speaking, cryptojacking threat group that targets cloud environments. The group typically uses cryptojacking malware and have been active since at least April 2020.[1] TeamTNT activity throughout 2021 has targeted AWS, Docker, GCP, Linux, Kubernetes, and Windows, which corresponds to usual TeamTNT activity.[2]
Technical Analysis
Scripts (/cmd/)
Figure 1 - Overview of /cmd/
Contained on the server are approximately 50 scripts, most of which are already documented, located in the /cmd/ directory. The objective of the scripts vary and include the following:
AWS Credential Stealer
Diamorphine Rootkit
IP Scanners
Mountsploit
Scripts to set up utils
Scripts to setup miners
Scripts to remove previous miners
Figure 2 - Snippet of AWS Credential Stealer Script
Some notable scripts, for example, is the script that steals AWS EC2 credentials, shown above in Figure 2. The AWS access key, secret key, and token are piped into a text file that is uploaded to the Command and Control (C2) server.
Figure 3 - Chimaera_Kubernetes_root_PayLoad_2.sh
Another interesting script is shown in Figure 3 above, which checks the architecture of the system, and retrieves the XMRig miner version for that architecture from another open TeamTNT server, 85.214.149[.]236.
Binaries (/bin/)
Figure 4 - Overview of /bin
Within the /bin/ folder, shown in Figure 4 above, there is a collection of malicious binaries and utilities that TeamTNT use in their operations.
Among the files are well-known samples that are attributed to TeamTNT, including the Tsunami backdoor and a XMRig cryptominer. Some of the tools have the source code located on the server, such as TeamTNT Bot. The folder /a.t.b contains the source code for the TeamTNT bot, shown in Figures 5 and 6 below. In addition, the same binaries have been found on a TeamTNT Docker, noted in Appendix A.

S.O.V.A. – A New Android Banking Trojan with Fowl Intentions
(published: September 10, 2021)
ThreatFabric researchers have discovered a new Android banking trojan called S.O.V.A. The malware is still in the development and testing phase and the threat actor is publicly-advertising S.O.V.A. for trial runs targeting banks to improve its functionality. The trojan’s primary objective is to steal personally identifiable information (PII). This is conducted through overlay attacks, keylogging, man-in-the-middle attacks, and session cookies theft, among others. The malware author is also working on other features such as distributed denial-of-service (DDoS) and ransomware on S.O.V.A.’s project roadmap.
Analyst Comment: Always keep your mobile phone fully patched with the latest security updates. Only use official locations such as the Google Play Store / Apple App Store to obtain your software, and avoid downloading applications, even if they appear legitimate, from third-party stores. Furthermore, always review the permissions an app will request upon installation.

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.

NoxPlayer Supply-Chain Attack is Likely The Work of Gelsemium Hackers
(published: June 14, 2021)
ESET researchers have discovered malicious activity dating back to at least 2014 attributed to the Gelsemium cyberespionage group. The group targets electronics manufacturers, governments, religious entities in multiple countries throughout East Asia and the Middle East. Gelsemium demonstrated sophistication in their infection chain with extensive configurations, multiple implants at each stage, and modifying settings on-the-fly for delivering the final payload. The dropper, called Gelsemine, will drop a loader called Gelsenicine that will deliver the final payload, called Gelsevirine.
Analyst Comment: Threat actors are always adapting to the security environment to remain effective. New techniques can still be spotted with behavioural analysis defenses and social engineering training. Ensure that your company's firewall blocks all entry points for unauthorized users, and maintain records of how normal traffic appears on your network. Therefore, it will be easier to spot unusual traffic and connections to and from your network to potentially identify malicious activity. Furthermore, ensure that your employees are educated about the risks of opening attachments, particularly from unknown senders and any attachment that requests macros be enabled.

BackdoorDiplomacy: upgrading from Quarian to Turian
(published: June 10, 2021)
A new advanced persistent threat (APT) group, dubbed BackdoorDiplomacy, has been targeting ministries of foreign affairs (MOFAs) and telecommunication companies located in Africa and the Middle East since at least 2017, according to ESET researchers. The group was observed targeting “vulnerable internet-exposed devices such as web servers and management interfaces for networking equipment.” BackdoorDiplomacy’s objective is to access a system, use pentesting tools for lateral movement, and install a custom backdoor called “Turian,” which is based on the Quarian backdoor.
Analyst Comment: It is important that your company has patch-maintenance policies in place, particularly if there are numerous internet-facing services your company uses or provides. Once a vulnerability has been reported on in open sources, threat actors will likely attempt to incorporate the exploitation of the vulnerability into their malicious operations. Patches should be reviewed and applied as soon as possible to prevent potential malicious activity.
