A threat actor attempted to use an AV/EDR bypass tool in an extortion attempt. Instead, the tool provided Unit 42 insight into the threat actor.
Existing low-level access for security solutions will undergo a rework
FIN7 (aka Carbon Spider, ELBRUS, Sangria Tempest) is a Russian APT group that is primarily known for targeting the U.S. retail, restaurant, and hospitality sectors since mid-2015.
Learn how SafeBreach developed malware integrated within Palo Alto Networks Cortex XDR, exploiting its ransomware protection feature.
It is trivially possible to disable the Cortex EDR as a non-admin user by triggering a repair function. This is only working, if the Tamper Protection is not enforced! TL;DR; Trigger the repair via GUID Disrupt it when EDR is deactivated Done
Our research team is committed to continuously identifying potential security vulnerabilities and techniques that threat actors may exploit to bypass existing security controls. In this blog post, our team is detailing on a comprehensive research specifically focused on process injection techniques utilized by attackers to deceive robust security products integrated into the security stack, such as EDRs and XDRs. Throughout the blog post, we will delve into various process injection techniques e
A global sensation since its initial release at the end of last year, ChatGPT's popularity among consumers and IT professionals alike has stirred up cybersecurity nightmares about how it can be used to exploit system vulnerabilities. A key problem, cybersecurity experts have demonstrated, is the ability of ChatGPT and other large language models (LLMs) to generate polymorphic, or mutating, code to evade endpoint detection and response (EDR) systems.
A threat actor known as Spyboy is promoting a Windows defense evasion tool called
On May 21, 2023, an online persona named spyboy began advertising an endpoint defense evasion tool for the Windows operating system via the Russian-language forum Ramp. The author claims that the software — seen in a demonstration video as being titled “Terminator” — can bypass twenty three (23) EDR and AV controls. At time of writing, spyboy is pricing the software from $300 USD (single bypass) to $3,000 USD (all-in-one bypass).
Endpoint Detection & Response systems (EDR),
delivered by in-house teams or as part of a managed
service, are a feature of modern intrusion detection
and remediation operations. This success is a problem
for attackers, and malicious actors have worked to
find new ways to evade EDR detection capabilities.
Researchers warn that polymorphic malware created with ChatGPT and other LLMs will force a reinvention of security automation.
Driver based attacks against security products are on the rise
Black Basta operational TTPs are described here in full detail, revealing previously unknown tools and techniques and a link to FIN7.
EDR or Endpoint Detection and Response refers to an integrated endpoint security solution which continuously monitors end-point user's devices and try to prevent anomalies like Malware, Ransomware by using automated rule based response method.
Caen a profité des suites d’un démonstrateur de l'EDR d'HarfangLab en attente de contractualisation pour détecter les prémices du possible déploiement d’un rançongiciel. L’intrusion est avérée, un nettoyage en cours, mais le chiffrement a été évité. Et très probablement le vol de données aussi.
