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 our always-online world, we\'re facing a new kind of cyber threat that\'s just as sneaky as it is harmful: subtextual attacks. These aren\'t your run-of-the-mill security breaches; they\'re cunningly crafted messages that may look harmless—but they actually carry a dangerous payload within them. Join me as we take a closer look at this under-the-radar, but still dangerous, threat. We\'ll explore how these deceptive messages can sneak past our defenses, trick people into taking unwanted actions, and steal sensitive information without ever tripping an alarm. The Rise of Subtextual Attacks Unlike traditional cyber attacks, which are often direct and identifiable, subtextual attacks rely on subtlety and deception. Attackers craft messages that on the surface appear harmless or unrelated to any malicious activity. However, embedded within these communications are instructions, links, or information that can compromise security, manipulate behavior, or extract sensitive data. And not only is big data paramount in advertising and other avenues, but it’s also like keeping everything in your wallet—it’s convenient, helpful even, but signals to attackers that you’re indeed willing to put all your eggs in one basket when it comes to communications. These attacks exploit the nuances of language and context and require a sophisticated understanding of human communication and digital interaction patterns. For instance, a seemingly benign email might include a specific choice of words or phrases that, when interpreted correctly, reveal a hidden command or a disguised link to a malicious site. Psychological Manipulation Through Subtext Subtextual attacks also leverage psychological manipulation, influencing individuals to act in ways that compromise security or divulge confidential information. By understanding the psychological triggers and behavioral patterns of targets, attackers craft messages that subtly guide the recipient\'s actions. For instance, an attacker might use social engineering techniques combined with subtextual cues to convince a user to bypass normal security protocols. An email that seems to come from a trusted colleague or superior, containing subtle suggestions or cues, can be more effective in eliciting certain actions than a direct request or command. Attackers can also exploit the principle of urgency or scarcity, embedding subtle cues in communications that prompt the recipient to act quickly, bypassing their usual critical thinking or security procedures. The Evolution of Digital Forensics To combat the growing rise of subtextual attacks, the field of digital forensics has evolved significantly over the past decade. Initially focused on recovering and analyzing electronic information to investigate crime, digital forensics now incorporates advanced linguistic analysis, data pattern recognition, and machine learning to detect hidden threats.

Les acteurs de la menace ne fonctionnent plus dans les silos.Aujourd'hui, ils utilisent plusieurs canaux tels que SMS, e-mail, fausses pages Web et comptes cloud compromis.Ils utilisent ces différents canaux pour établir la persistance et compromettre les identités afin qu'ils puissent augmenter les privilèges et se déplacer latéralement. ProofPoint Research Threat a récemment observé des campagnes dans lesquelles les acteurs de la menace ont utilisé des attaques multicanaux pour cibler l'industrie du commerce de détail.La chaîne d'attaque et la chronologie montrent comment les acteurs de la menace (TA) passent d'une organisation ciblée à l'autre.Chaque fois que leur accès non autorisé est révoqué ou épuisé, les attaquants passent à la prochaine cible. La chaîne d'attaque multicanal qui cible les détaillants mondiaux. Dans nos recherches, ces campagnes commencent par une attaque de smims.Une attaque de smims, également connue sous le nom de phishing SMS, utilise des SMS pour inciter les destinataires à faire ce que l'attaquant veut qu'ils fassent.Cela pourrait fournir leurs informations personnelles ou financières, en cliquant sur des liens malveillants ou en téléchargeant des applications logicielles nocives.Les messages de smirs utilisent des thèmes de billets de support courts pour attirer les victimes des sites de phishing de l'acteur de menace. Exemples de messages de phishing SMS avec des thèmes de billets de support. Dans la campagne que nous avons observée, l'AT a utilisé une page de phishing Microsoft personnalisée qui comprenait la marque de l'organisation ciblée \\.Cette page a conduit les utilisateurs via le flux d'autorisation MFA pour collecter leurs informations d'identification. Exemple de page Microsoft Phish personnalisée avec la marque Target Organisation \\. Une fois que l'AT a capturé les informations d'identification, ils ont compromis les comptes d'utilisateurs.Takever post-compte (ATO), les attaquants ont utilisé plusieurs méthodes pour maintenir un accès persistant et masquer leurs activités non autorisées.Ceux-ci inclus: Manipulation MFA.Les attaquants ont utilisé des comptes détournés pour enregistrer leurs propres méthodes MFA. Inscription de nouveaux appareils via des applications Microsoft natives (telles que l'inscription Intune).Cela a aidé les attaquants à cacher leurs activités non autorisées et à accéder à certaines ressources. Utilisation malveillante du VPN d'entreprise.Le TA a utilisé les produits VPN et ZTNA de la victime et plusieurs de leurs propres clients VPN pour accéder à des ressources telles que les produits de sécurité et les environnements de production. Les attaquants ont eu accès au portail SSO de l'organisation, qui à son tour a donné accès à de nombreux autres services internes et applications tierces (3PA).Les attaquants ont énuméré toutes les applications connectées au PDI et ont tenté de trouver des liens API qu'ils pourraient abuser.Ensuite, ils sont entrés dans une application commerciale spécifique pour créer des cartes-cadeaux contrefaits. Attribution L'acteur de menace de cette attaque est appelé "atlas lion" qui a des zones potentielles de chevauchement avec l'acteur Microsoft Tracks sous le nom de Storm-0539.Cet acteur de menace est «connu pour cibler les organisations de vente au détail pour la fraude et le vol de cartes-cadeaux en utilisant des e-mails et un phishing SMS très sophistiqués pendant la saison des achats des fêtes».Bien que ces attaques ne soient pas originaires de courriels, leur chevauchement dans les TTP (tactiques, techniques et procédures) nous amène à croire que l'ensemble d'activités peut s'aligner sur l'acteur de menace que nous suivons en tant que TA4901.Cet TA cible les sociétés dans les secteurs de télécommunications et de vente au détail depuis au moins 2018.

## Snapshot Microsoft has observed several notable cyber and influence trends from China and North Korea since June 2023 that demonstrate not only doubling down on familiar targets, but also attempts to use more sophisticated influence techniques to achieve their goals. Chinese cyber actors broadly selected three target areas over the last seven months. - One set of Chinese actors extensively targeted entities across the South Pacific Islands. - A second set of Chinese activity continued a streak of cyberattacks against regional adversaries in the South China Sea region. - Meanwhile, a third set of Chinese actors compromised the US defense industrial base. Chinese influence actors-rather than broadening the geographic scope of their targets-honed their techniques and experimented with new media. Chinese influence campaigns continued to refine AI-generated or AI-enhanced content. The influence actors behind these campaigns have shown a willingness to **both amplify AI-generated media that benefits their strategic narratives, as well as create their own video, memes, and audio content**. Such tactics have been used in campaigns stoking divisions within the United States and exacerbating rifts in the Asia-Pacific region-including Taiwan, Japan, and South Korea. These campaigns achieved varying levels of resonance with no singular formula producing consistent audience engagement. North Korean cyber actors made headlines for **increasing software supply chain attacks and cryptocurrency heists over the past year**. While strategic spear-phishing campaigns targeting researchers who study the Korean Peninsula remained a constant trend, North Korean threat actors appeared to make greater use of legitimate software to compromise even more victims. ## Activity Overview ### Chinese cyber operations target strategic partners and competitors #### Gingham Typhoon targets government, IT, and multinational entities across the South Pacific Islands **** *Figure 1: Observed events from Gingham Typhoon from June 2023 to January 2024 highlights their continued focus on South Pacific Island nations. However, much of this targeting has been ongoing, reflecting a yearslong focus on the region. Geographic locations and diameter of symbology are representational. * During the summer of 2023, Microsoft Threat Intelligence observed extensive activity from China-based espionage group Gingham Typhoon that targeted nearly every South Pacific Island country. Gingham Typhoon is the most active actor in this region, hitting international organizations, government entities, and the IT sector with complex phishing campaigns. Victims also included vocal critics of the Chinese government. Diplomatic allies of China who were victims of recent Gingham Typhoon activity include executive offices in government, trade-related departments, internet service providers, as well as a transportation entity. Heightened geopolitical and diplomatic competition in the region may be motivations for these offensive cyber activities. China pursues strategic partnerships with South Pacific Island nations to expand economic ties and broker diplomatic and security agreements. Chinese cyber espionage in this region also follows economic partners. For example, Chinese actors engaged in large-scale targeting of multinational organizations in Papua New Guinea, a longtime diplomatic partner that is benefiting from multiple Belt and Road Initiative (BRI) projects including the construction of a major highway which links a Papua New Guinea government building to the capital city\'s main road.

2024-04-05 06:00:25 | Amélioration de la détection et de la réponse: plaider en matière de tromperies Improving Detection and Response: Making the Case for Deceptions (lien direct) |
Let\'s face it, most enterprises find it incredibly difficult to detect and remove attackers once they\'ve taken over user credentials, exploited hosts or both. In the meantime, attackers are working on their next moves. That means data gets stolen and ransomware gets deployed all too often. And attackers have ample time to accomplish their goals. In July 2023, the reported median dwell time was eight days. That\'s the time between when an attacker accesses their victim\'s systems and when the attack is either detected or executed. Combine that data point with another one-that attackers take only 16 hours to reach Active Directory once they have landed-and the takeaway is that threats go undetected for an average of seven days. That\'s more than enough time for a minor security incident to turn into a major business-impacting breach. How can you find and stop attackers more quickly? The answer lies in your approach. Let\'s take a closer look at how security teams typically try to detect attackers. Then, we can better understand why deceptions can work better. What is the problem with current detection methods? Organizations and their security vendors have evolved when it comes to techniques for detecting active threats. In general, detection tools have focused on two approaches-finding files or network traffic that are “known-bad” and detecting suspicious or risky activity or behavior. Often called signature-based detection, finding “known-bad” is a broadly used tool in the detection toolbox. It includes finding known-bad files like malware, or detecting traffic from known-bad IPs or domains. It makes you think of the good old days of antivirus software running on endpoints, and about the different types of network monitoring or web filtering systems that are commonplace today. The advantage of this approach is that it\'s relatively inexpensive to build, buy, deploy and manage. The major disadvantage is that it isn\'t very effective against increasingly sophisticated threat actors who have an unending supply of techniques to get around them. Keeping up with what is known-bad-while important and helpful-is also a bit like a dog chasing its tail, given the infinite internet and the ingenuity of malicious actors. The rise of behavior-based detection About 20 years ago, behavioral-based detections emerged in response to the need for better detection. Without going into detail, these probabilistic or risk-based detection techniques found their way into endpoint and network-based security systems as well as SIEM, email, user and entity behavior analytics (UEBA), and other security systems. The upside of this approach is that it\'s much more nuanced. Plus, it can find malicious actors that signature-based systems miss. The downside is that, by definition, it can generate a lot of false positives and false negatives, depending on how it\'s tuned. Also, the high cost to build and operate behavior-based systems-considering the cost of data integration, collection, tuning, storage and computing-means that this approach is out of reach for many organizations. This discussion is not intended to discount the present and future benefits of newer analytic techniques such as artificial intelligence and machine learning. I believe that continued investments in behavior-based detections can pay off with the continued growth of security data, analytics and computing power. However, I also believe we should more seriously consider a third and less-tried technique for detection. Re-thinking detection Is it time to expand our view of detection techniques? That\'s the fundamental question. But multiple related questions are also essential: Should we be thinking differently about what\'s the best way to actively detect threats? Is there a higher-fidelity way to detect attackers that is cost-effective and easy to deploy and manage? Is there another less-tried approach for detecting threat actors-beyond signature-based and behavior-based methods-that can dra | Ransomware Malware Tool Vulnerability Threat | ★★ | |

Since the initial disclosure of CVE-2023-46805 and CVE-2024-21887 on Jan. 10, 2024, Mandiant has conducted multiple incident response engagements across a range of industry verticals and geographic regions. Mandiant\'s previous blog post, Cutting Edge, Part 3: Investigating Ivanti Connect Secure VPN Exploitation and Persistence Attempts, details zero-day exploitation of CVE-2024-21893 and CVE-2024-21887 by a suspected China-nexus espionage actor that Mandiant tracks as UNC5325. This blog post, as well as our previous reports detailing Ivanti exploitation, help to underscore the different types of activity that Mandiant has observed on vulnerable Ivanti Connect Secure appliances that were unpatched or did not have the appropriate mitigation applied. Mandiant has observed different types of post-exploitation activity across our incident response engagements, including lateral movement supported by the deployment of open-source tooling and custom malware families. In addition, we\'ve seen these suspected China-nexus actors evolve their understanding of Ivanti Connect Secure by abusing appliance-specific functionality to achieve their objectives. As of April 3, 2024, a patch is readily available for every supported version of Ivanti Connect Secure affected by the vulnerabilities. We recommend that customers follow Ivanti\'s latest patching guidance and instructions to prevent further exploitation activity. In addition, Ivanti released a new enhanced external integrity checker tool (ICT) to detect potential attempts of malware persistence across factory resets and system upgrades and other tactics, techniques, and procedures (TTPs) observed in the wild.

Proofpoint\'s Threat Research team joined up with the Team Cymru S2 Threat Research team, in a collaborative effort to provide the information security community with a comprehensive view of the threat activity described. Key takeaways Proofpoint first observed new malware named Latrodectus appear in email threat campaigns in late November 2023. While use of Latrodectus decreased in December 2023 through January 2024, Latrodectus use increased in campaigns throughout February and March 2024. It was first observed in Proofpoint data being distributed by threat actor TA577 but has been used by at least one other threat actor, TA578. Latrodectus is an up-and-coming downloader with various sandbox evasion functionality. While similar to IcedID, Proofpoint researchers can confirm it is an entirely new malware, likely created by the IcedID developers. Latrodectus shares infrastructure overlap with historic IcedID operations. While investigating Latrodectus, researchers identified new, unique patterns in campaign IDs designating threat actor use in previous IcedID campaigns. Overview Proofpoint identified a new loader called Latrodectus in November 2023. Researchers have identified nearly a dozen campaigns delivering Latrodectus, beginning in February 2024. The malware is used by actors assessed to be initial access brokers (IABs). Latrodectus is a downloader with the objective of downloading payloads and executing arbitrary commands. While initial analysis suggested Latrodectus was a new variant of IcedID, subsequent analysis confirmed it was a new malware most likely named Latrodectus, based on a string identified in the code. Based on characteristics in the disassembled sample and functionality of the malware, researchers assess the malware was likely written by the same developers as IcedID. This malware was first observed being distributed by TA577, an IAB known as a prolific Qbot distributor prior to the malware\'s disruption in 2023. TA577 used Latrodectus in at least three campaigns in November 2023 before reverting to Pikabot. Since mid-January 2024, researchers observed it being used almost exclusively by TA578 in email threat campaigns. Campaign details TA577 TA577 was only observed using Latrodectus in three campaigns, all occurring in November 2023. Notably, a campaign that occurred on 24 November 2023 deviated from previously observed TA577 campaigns. The actor did not use thread hijacking, but instead used contained a variety of different subjects with URLs in the email body. The URLs led to the download of a JavaScript file. If executed, the JavaScript created and ran several BAT files that leveraged curl to execute a DLL and ran it with the export “scab”. Figure 1: Example TA577 campaign delivering Latrodectus. On 28 November 2023, Proofpoint observed the last TA577 Latrodectus campaign. The campaign began with thread hijacked messages that contained URLs leading to either zipped JavaScript files or zipped ISO files. The zipped JavaScript file used curl to download and execute Latrodectus. The zipped ISO file contained a LNK file used to execute the embedded DLL, Latrodectus. Both attack chains started the malware with the export “nail”. TA578 Since mid-January 2024, Latrodectus has been almost exclusively distributed by TA578. This actor typically uses contact forms to initiate a conversation with a target. In one campaign observed on 15 December 2023, Proofpoint observed TA578 deliver the Latrodectus downloader via a DanaBot infection. This December campaign was the first observed use of TA578 distributing Latrodectus. On 20 February 2024, Proofpoint researchers observed TA578 impersonating various companies to send legal threats about alleged copyright infringement. The actor filled out a contact form on multiple targets\' websites, with text containing unique URLs and included in the URI both the domain of the site that initiated the contact form (the target), and the name of the impersonated company (to further the legitimacy | Ransomware Malware Tool Threat Prediction | ★★★ | |

#### Description Trend Micro analyzed a cyberespionage attack the company has attributed to Earth Freybug, a subset of APT41 (tracked by Microsoft as [Brass Typhoon](https://sip.security.microsoft.com/intel-profiles/f0aaa62bfbaf3739bb92106688e6a00fc05eafc0d4158b0e389b4078112d37c6?)). According to Trend Micro, Earth Freybug has been active since at least 2012 and the Chinese-linked group has been active in espionage and financially motivated attacks. Earth Freybug employs diverse tools like LOLBins and custom malware, targeting organizations globally. The attack used techniques like dynamic link library (DLL) hijacking and API unhooking to avoid monitoring for a new malware called UNAPIMON. UNAPIMON evades detection by preventing child processes from being monitored. The attack flow involved creating remote scheduled tasks and executing reconnaissance commands to gather system information. Subsequently, a backdoor was launched using DLL side-loading via a service called SessionEnv, which loads a malicious DLL. UNAPIMON, the injected DLL, uses API hooking to evade monitoring and execute malicious commands undetected, showcasing the attackers\' sophistication.

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. If you’ve ever worked in an IT department, you know how easily a single misclick can lead to data breaches and system compromises. Preventive efforts are critical since there’s no reliable way to truly eliminate insider threats. Can robust access controls protect your organization? The impact of insider threats on organizations Insider threats are a prominent danger regardless of the industry you’re in. In fact, 98% of U.S. organizations report being slightly to extremely vulnerable to them. This figure reveals how many are unconfident in their existing deterrents, highlighting the importance of preventative efforts. Even if you don’t believe anyone at your workplace would intentionally cause damage, you should still be wary — insider threats aren’t always malicious. Negligent employees are responsible for 60% of data breaches, meaning carelessness is a more common driver. Unfortunately, the fact that negligence is the primary driver of insider threat attacks isn’t a good thing — it means a single misclick could put your entire organization at risk. Robust access controls are among the best solutions to this situation since they can prevent careless employees from leaking data or unintentionally escalating an attacker’s permissions. Access control mechanisms are crucial for threat mitigation The main way robust access control mechanisms are crucial for addressing insider threats is through unauthorized access mitigation. Employees, whether acting negligently or with ill intent, won’t be able to do any damage to your organization when their permissions limit them from retrieving or editing sensitive data storage systems. No matter how long you’ve spent in the IT department, you know how irresponsible some employees are when dealing with sensitive data, intellectual property or identifiable details. Access control mechanisms keep information assets out of reach of most of the people in your organization, safeguarding them from being tampered with or exfiltrated. If an attacker successfully enters your organization’s systems or network, robust access control mechanisms restrict their lateral movement. Since they aren’t authorized personnel, they aren’t granted meaningful permissions. This act minimizes the damage they can do and prevents them from compromising anything else. Even if an attacker has one of your colleague’s lost or stolen devices, access controls block them from being able to do anything meaningful. Authentication measures prevent them from accessing your organization’s systems and exfiltrating sensitive data. It also helps keep them from escalating their privileges, minimizing their impact. With robust access control mechanisms, you can quickly identify indicators of compromise (IOCs) to stop threats before they become an issue. For example, spotting concurrent logins on a single user account means an attacker is using legitimate credentials, indicating a brute force, phishing or keylogging attack. Which access control systems should you implement? Although insider threats pose an issue regardless of your industry or organization’s size, you can find ways to prevent them from doing any damage. You should consider implementing access control systems to detect and deter unauthorized action, mitigating data breaches and system compromises. A standard system to consid | Tool Threat | ★★★ | |

2024-04-03 06:00:40 | Les acteurs de la menace offrent des logiciels malveillants via les fissures du jeu vidéo YouTube Threat Actors Deliver Malware via YouTube Video Game Cracks (lien direct) |
Key takeaways Proofpoint identified multiple YouTube channels distributing malware by promoting cracked and pirated video games and related content. The video descriptions include links leading to the download of information stealers. The activity likely targets consumer users who do not have the benefits of enterprise-grade security on their home computers. Overview Threat actors often target home users because they do not have the same resources or knowledge to defend themselves from attackers compared to enterprises. While the financial gain might not be as large as attacks perpetrated on corporations, the individual victims likely still have data like credit cards, cryptocurrency wallets, and other personal identifiable information (PII) stored on their computers which can be lucrative to criminals. Proofpoint Emerging Threats has observed information stealer malware including Vidar, StealC, and Lumma Stealer being delivered via YouTube in the guise of pirated software and video game cracks. The videos purport to show an end user how to do things like download software or upgrade video games for free, but the link in the video descriptions leads to malware. Many of the accounts that are hosting malicious videos appear to be compromised or otherwise acquired from legitimate users, but researchers have also observed likely actor-created and controlled accounts that are active for only a few hours, created exclusively to deliver malware. Third-party researchers have previously published details on fake cracked software videos used to deliver malware. The distribution method is particularly notable due to the type of video games the threat actors appear to promote. Many of them appear to be targeted to younger users including games popular with children, a group that is less likely to be able to identify malicious content and risky online behaviors. During our investigation, Proofpoint Emerging Threats reported over two dozen accounts and videos distributing malware to YouTube, which removed the content. Example account The following is an example of a suspected compromised account (or potentially sold to a new “content creator”) used to deliver malware. Indicators of a suspected compromised or otherwise acquired account include significant gaps of time between the videos posted, content that vastly differs from previously published videos, differences in languages, and descriptions of the videos containing likely malicious links, among other indicators. The account has around 113,000 subscribers, and the account displays a grey check mark which indicates the account owner has met verified channel requirements including verifying their identity. Example of a verified YouTube account with a large following, suspected to be compromised. When Proofpoint researchers identified the account, the majority of the account\'s videos had been posted one year or more previously, and all had titles written in Thai. However, when the account was identified, twelve (12) new English language videos had been posted within a 24-hour period, all related to popular video games and software cracks. All of the new video descriptions included links to malicious content. Some of the videos had over 1,000 views, possibly artificially increased by bots to make the videos seem more legitimate. Screenshot of a suspected compromised YouTube account distributing malware comparing upload dates. In one example, a video purported to contain a character enhancement for a popular video game with a MediaFire link in the description. The MediaFire URL led to a password-protected file (Setup_Pswrd_1234.rar) containing an executable (Setup.exe) that, if executed, downloaded and installed Vidar Stealer malware. The video was uploaded to the suspected compromised account seven (7) hours prior to our investigation. Around the same time the video was posted, several comments purported to attest to the legitimacy of the software crack. It is likely those accounts and comments were created by the video | Malware Tool Threat | ★★★ | |

2024-03-28 18:16:18 | Adressez désinfectant pour le firmware à métal nu Address Sanitizer for Bare-metal Firmware (lien direct) |
Posted by Eugene Rodionov and Ivan Lozano, Android Team With steady improvements to Android userspace and kernel security, we have noticed an increasing interest from security researchers directed towards lower level firmware. This area has traditionally received less scrutiny, but is critical to device security. We have previously discussed how we have been prioritizing firmware security, and how to apply mitigations in a firmware environment to mitigate unknown vulnerabilities. In this post we will show how the Kernel Address Sanitizer (KASan) can be used to proactively discover vulnerabilities earlier in the development lifecycle. Despite the narrow application implied by its name, KASan is applicable to a wide-range of firmware targets. Using KASan enabled builds during testing and/or fuzzing can help catch memory corruption vulnerabilities and stability issues before they land on user devices. We\'ve already used KASan in some firmware targets to proactively find and fix 40+ memory safety bugs and vulnerabilities, including some of critical severity. Along with this blog post we are releasing a small project which demonstrates an implementation of KASan for bare-metal targets leveraging the QEMU system emulator. Readers can refer to this implementation for technical details while following the blog post. Address Sanitizer (ASan) overview Address sanitizer is a compiler-based instrumentation tool used to identify invalid memory access operations during runtime. It is capable of detecting the following classes of temporal and spatial memory safety bugs: out-of-bounds memory access use-after-free double/invalid free use-after-return ASan relies on the compiler to instrument code with dynamic checks for virtual addresses used in load/store operations. A separate runtime library defines the instrumentation hooks for the heap memory and error reporting. For most user-space targets (such as aarch64-linux-android) ASan can be enabled as simply as using the -fsanitize=address compiler option for Clang due to existing support of this target both in the toolchain and in the libclang_rt runtime. However, the situation is rather different for bare-metal code which is frequently built with the none system targets, such as arm-none-eabi. Unlike traditional user-space programs, bare-metal code running inside an embedded system often doesn\'t have a common runtime implementation. As such, LLVM can\'t provide a default runtime for these environments. To provide custom implementations for the necessary runtime routines, the Clang toolchain exposes an interface for address sanitization through the -fsanitize=kernel-address compiler option. The KASan runtime routines implemented in the Linux kernel serve as a great example of how to define a KASan runtime for targets which aren\'t supported by default with -fsanitize=address. We\'ll demonstrate how to use the version of address sanitizer originally built for the kernel on other bare-metal targets. KASan 101 Let\'s take a look at the KASan major building blocks from a high-level perspective (a thorough explanation of how ASan works under-the-hood is provided in this whitepaper). The main idea behind KASan is that every memory access operation, such as load/store instructions and memory copy functions (for example, memm | Tool Vulnerability Mobile Technical | ★★ | |

Written by: Andrew Oliveau
Over the last several years, the security community has witnessed an uptick in System Center Configuration Manager (SCCM)-related attacks. From extracting network access account (NAA) credentials to deploying malicious applications to targeted devices, SCCM attacks have aided in accomplishing complex objectives and evading existing detections. Mandiant\'s Red Team has utilized SCCM technology to perform novel attacks against mature clients where conventional methodology was not possible. One such SCCM attack is introduced in this blog post. There was a time when red teamers with elevated privileges on a Windows system could effortlessly inject shellcode into an unsuspecting user\'s processes. This allowed red teamers to carry out post-exploitation activities within that new process, such as keylogging or accessing LDAP as the affected user. However, as endpoint detection and response (EDR) systems have improved, remote process injection has turned into a risky operation, pushing red teamers to seek alternative methods to hijack a user\'s session. Enter CcmExec, a service native to SCCM Windows clients that has an interesting design that is useful for red teamers. In this blog post, we delve into how the CcmExec service can be utilized for session hijacking and introduce CcmPwn, a tool designed to facilitate this technique. Finally, we will discuss detection strategies for security teams. AppDomainManager Injection Before diving into CcmExec, it is important to understand the intricacies of AppDomainManager injection, a loader hijacking technique used by attackers to execute arbitrary code within a .NET application. In essence, the .NET framework provides a way to manage application domains, which are isolated environments where .NET applications can run code. The AppDomainManager class is a key part of this infrastructure, responsible for creating and managing these application domains. However, if an attacker were to override the AppDomainManager class constructor, they could force the hosting application to run attacker-defined behavior when creating an application domain. The most common method to perform AppDomainManager injection is through a .config file. This approach involves modifying the application\'s configuration file to specify a custom dynamic-link library file (DLL) and AppDomainManager to be executed by the .NET application. Here\'s how it\'s done: Create a custom AppDomainManager: Develop a class that derives from AppDomainManager and includes malicious code. Compile this class into a DLL.
