2024-03-05 19:03:47 | Rester en avance sur les acteurs de la menace à l'ère de l'IA Staying ahead of threat actors in the age of AI (lien direct) |
## Snapshot Over the last year, the speed, scale, and sophistication of attacks has increased alongside the rapid development and adoption of AI. Defenders are only beginning to recognize and apply the power of generative AI to shift the cybersecurity balance in their favor and keep ahead of adversaries. At the same time, it is also important for us to understand how AI can be potentially misused in the hands of threat actors. In collaboration with OpenAI, today we are publishing research on emerging threats in the age of AI, focusing on identified activity associated with known threat actors, including prompt-injections, attempted misuse of large language models (LLM), and fraud. Our analysis of the current use of LLM technology by threat actors revealed behaviors consistent with attackers using AI as another productivity tool on the offensive landscape. You can read OpenAI\'s blog on the research [here](https://openai.com/blog/disrupting-malicious-uses-of-ai-by-state-affiliated-threat-actors). Microsoft and OpenAI have not yet observed particularly novel or unique AI-enabled attack or abuse techniques resulting from threat actors\' usage of AI. However, Microsoft and our partners continue to study this landscape closely. The objective of Microsoft\'s partnership with OpenAI, including the release of this research, is to ensure the safe and responsible use of AI technologies like ChatGPT, upholding the highest standards of ethical application to protect the community from potential misuse. As part of this commitment, we have taken measures to disrupt assets and accounts associated with threat actors, improve the protection of OpenAI LLM technology and users from attack or abuse, and shape the guardrails and safety mechanisms around our models. In addition, we are also deeply committed to using generative AI to disrupt threat actors and leverage the power of new tools, including [Microsoft Copilot for Security](https://www.microsoft.com/security/business/ai-machine-learning/microsoft-security-copilot), to elevate defenders everywhere. ## Activity Overview ### **A principled approach to detecting and blocking threat actors** The progress of technology creates a demand for strong cybersecurity and safety measures. For example, the White House\'s Executive Order on AI requires rigorous safety testing and government supervision for AI systems that have major impacts on national and economic security or public health and safety. Our actions enhancing the safeguards of our AI models and partnering with our ecosystem on the safe creation, implementation, and use of these models align with the Executive Order\'s request for comprehensive AI safety and security standards. In line with Microsoft\'s leadership across AI and cybersecurity, today we are announcing principles shaping Microsoft\'s policy and actions mitigating the risks associated with the use of our AI tools and APIs by nation-state advanced persistent threats (APTs), advanced persistent manipulators (APMs), and cybercriminal syndicates we track. These principles include: - **Identification and action against malicious threat actors\' use:** Upon detection of the use of any Microsoft AI application programming interfaces (APIs), services, or systems by an identified malicious threat actor, including nation-state APT or APM, or the cybercrime syndicates we track, Microsoft will take appropriate action to disrupt their activities, such as disabling the accounts used, terminating services, or limiting access to resources. - **Notification to other AI service providers:** When we detect a threat actor\'s use of another service provider\'s AI, AI APIs, services, and/or systems, Microsoft will promptly notify the service provider and share relevant data. This enables the service provider to independently verify our findings and take action in accordance with their own policies. - **Collaboration with other stakeholders:** Microsoft will collaborate with other stakeholders to regularly exchange information a | Ransomware Malware Tool Vulnerability Threat Studies Medical Technical | APT 28 ChatGPT APT 4 | ★★ |

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.

Lazarus Targets Chemical Sector
(published: April 14, 2022)
In January 2022, Symantec researchers discovered a new wave of Operation Dream Job. This operation, attributed to the North Korea-sponsored group Lazarus, utilizes fake job offers via professional social media and email communications. With the new wave of attacks, Operation Dream Job switched from targeting the defense, government, and engineering sectors to targeting South Korean organizations operating within the chemical sector. A targeted user executes an HTM file sent via a link. The HTM file is copied to a DLL file to be injected into the legitimate system management software. It downloads and executes the final backdoor: a trojanized version of the Tukaani project LZMA Utils library (XZ Utils) with a malicious export added (AppMgmt). After the initial access, the attackers gain persistence via scheduled tasks, move laterally, and collect credentials and sensitive information.
Analyst Comment: Organizations should train their users to recognize social engineering attacks including those posing as “dream job” proposals. Organizations facing cyberespionage threats should implement a defense-in-depth approach: layering of security mechanisms, redundancy, fail-safe defense processes.

Group-IB researchers have released their analysis of threat actor OldGremlin’s new March 2022 campaign. OldGremlin favored phishing as an initial infection vector, crafting intricate phishing emails that target Russian industries. The threat actors utilized the current war between Russia and Ukraine to add a sense of legitimacy to their emails, with claims that users needed to click a link to register for a new credit card, as current ones would be rendered useless by incoming sanctions.

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.

Executive summary
AT&T Alien Labs™ has observed new activity that has been attributed to the Lazarus adversary group potentially targeting engineering job candidates and/or employees in classified engineering roles within the U.S. and Europe. This assessment is based on malicious documents believed to have been delivered by Lazarus during the last few months (spring 2021). However, historical analysis shows the lures used in this campaign to be in line with others used to target these groups.
The purpose of this blog is to share the new technical intelligence and provide detection options for defenders. Alien Labs will continue to report on any noteworthy changes.
Key Takeaways:
Lazarus has been identified targeting defense contractors with malicious documents.
There is a high emphasis on renaming system utilities (Certutil and Explorer) to obfuscate the adversary’s activities (T1036.003).
Background
Since 2009, the known tools and capabilities believed to have been used by the Lazarus Group include DDoS botnets, keyloggers, remote access tools (RATs), and drive wiper malware. The most publicly documented malware and tools used by the group actors include Destover, Duuzer, and Hangman.
Analysis
Several documents identified from May to June 2021 by Twitter users were identified as being linked to the Lazarus group. Documents observed in previous campaigns lured victims with job opportunities for Boeing and BAE systems. These new documents include:
Rheinmetall_job_requirements.doc: identified by ESET Research.
General_motors_cars.doc: identified by Twitter user @1nternaut.
Airbus_job_opportunity_confidential.doc: identified by 360CoreSec.
The documents attempted to impersonate new defense contractors and engineering companies like Airbus, General Motors (GM), and Rheinmetall. All of these documents contain macro malware, which has been developed and improved during the course of this campaign and from one target to another. The core techniques for the three malicious documents are the same, but the attackers attempted to reduce the potential detections and increase the faculties of the macros.
First iteration: Rheinmetall
The first two documents from early May 2021 were related to a German Engineering company focused on the defense and automotive industries, Rheinmetall. The second malicious document appears to include more elaborate content, which may have resulted in the documents going unnoticed by victims.
The Macro has base64 encoded files, which are extracted and decoded during execution. Some of the files are split inside the Macro and are not combined until the time of decoding. One of the most distinctive characteristics of this Macro is how it evades detections of a MZ header encoded in base64 (TVoA, TVpB, TVpQ, TVqA, TVqQ or TVro), by separating the first two characters from the rest of the content, as seen in Figure 1.
Figure 1: Concealing of MZ header, as captured by Alien Labs.
The rest of the content is kept together in lines of 64 characters, and because of this, YARA rules can be used to detect other, typical executable content encoded in base64 aside of the MZ header. In this case, up to nine different YARA rules alerted to suspicious encoded strings in our Alien Labs analysis, like VirtualProtect, GetProcAddress, IsDe |

Researchers at securelist identified ransomware attacks from Andariel, a sub-group of Lazarus targeting South Korea. Attack victims included entities from manufacturing, home network service, media and construction sectors. These attacks involved malicious Microsoft Word documents containing a macro and used novel techniques to implant a multi-stage payload. The final payload was a ransomware custom made for this specific attack.
Analyst Comment: Users should be wary of documents that request Macros to be enabled. All employees should be educated on the risk of opening attachments from unknown senders. Anti-spam and antivirus protections should be implemented and kept up-to-date with the latest version to better ensure security.

In February 2021, BelialDemon advertised a new malware-as-a-service (MaaS) called Matanbuchus Loader and charged an initial rental price of $2,500. Malware loaders are malicious software that typically drop or pull down second-stage malware from command and control (C2) infrastructures.
Analyst Comment: Malware as a Service (MaaS) is a relatively new development, which opens the doors of crime to anyone with the money to pay for access. A criminal organization that wants to carry out a malware attack on a target no longer requires in-house technical expertise or infrastructure. Such attacks in most cases share tactics, techniques, and even IOCs. This highlights the importance of intelligence sharing for proactive protection.

Evolution of JSWorm Ransomware
(published: May 25, 2021)
JSWorm ransomware was discovered in 2019, and since then different variants have gained notoriety under different names such as Nemty, Nefilim, and Offwhite, among others. It has been used to target multiple industries with the largest concentration in engineering, and others including finance, healthcare, and energy. While the underlying code has been rewritten from C++ to Golang (and back again), along with revolving distribution methods, JSWorm remains a consistent threat.
Analyst Comment: Ransomware threats often affect organisations in two ways. First encrypting operational critical documents and data. In these cases EDR solutions will help to block potential Ransomwares and data backup solutions will help for restoring files in case an attack is successful. Secondly, sensitive customer and business files are exfiltrated and leaked online by ransomware gangs. DLP solutions will help to identify and block potential data exfiltration attempts. Whereas network segregation and encryption of critical data will play an important role in reducing the risk.

Bogus Android Clubhouse App Drops Credential-Swiping Malware
(published: March 19, 2021)
Researchers are warning of a fake version of the popular audio chat app Clubhouse, which delivers malware that steals login credentials for more than 450 apps. Clubhouse has burst on the social media scene over the past few months, gaining hype through its audio-chat rooms where participants can discuss anything from politics to relationships. Despite being invite-only, and only being around for a year, the app is closing in on 13 million downloads. The app is only available on Apple's App Store mobile application marketplace - though plans are in the works to develop one.
Analyst Comment: Use only the official stores to download apps to your devices. Be wary of what kinds of permissions you grant to applications. Before downloading an app, do some research.

Trojanized Xcode Project Slips XcodeSpy Malware to Apple Developers
(published: March 18, 2021)
Researchers from cybersecurity firm SentinelOne have discovered a malicious version of the legitimate iOS TabBarInteraction Xcode project being distributed in a supply-chain attack. The malware, dubbed XcodeSpy, targets Xcode, an integrated development environment (IDE) used in macOS for developing Apple software and applications. The malicious project is a ripped version of TabBarInteraction, a legitimate project that has not been compromised. Malicious Xcode projects are being used to hijack developer systems and spread custom EggShell backdoors.
Analyst Comment: Researchers attribute this new targeting of Apple developers to North Korea and Lazarus group: similar TTPs of compromising developer supply chain were discovered in January 2021 when North Korean APT was using a malicious Visual Studio project. Moreover, one of the victims of XcodeSpy is a Japanese organization regularly targeted by North Korea. A behavioral detection solution is required to fully detect the presence of XcodeSpy payloads.

‘Baka’ Javascript Skimmer Identified
(published: September 6, 2020)
Visa have issued a security alert based on identification of a new skimmer, named “Baka”. Based on analysis by Visa Payment Fraud Disruption, the skimmer appears to be more advanced, loading dynamically and using an XOR cipher for obfuscation. The attacks behind Baka are injecting it into checkout pages using a script tag, with the skimming code downloading from the Command and Control (C2) server and executing in memory to steal customer data.
Recommendation: eCommerce site owners must take every step necessary to secure their data and safeguard their payment card information. Visa has also released best practices in the security advisory.

Netwalker Ransomware Hits Argentinian Government, Demands $4 Million
(published: September 6, 2020)
The Argentinian immigration agency, Dirección Nacional de Migaciones suffered a ransomware attack that shut down border crossings. After receiving many tech support calls, the computer networks were shut down to prevent further spread of the ransomware, which led to a cecission in border crossings until systems were up again. The ransomware used in this attack is Netwalker ransomware, that left a ransom note demanding initalling $2 million, however when this wasn’t paid in the first week, the ransom increased to $4 million.
Recommendation: Ransomware can potentially be blocked by using endpoint protection solutions (HIDS). Always keep your important files backed up following the 3-2-1 rule: have at least 3 different copies, on 2 different mediums, with 1 off-site. In the case of ransomware infection, the affected system must be wiped and reformatted. Other devices on the network should be checked for similar infections. Always check for a decryptor before considering payment; avoid payment at all costs. Ransomware should be reported to law enforcement agencies who are doing their best to track these actors and prevent ransom from being a profitable business for cyber criminals.
