EDR as an Offensive Tool
Learn how SafeBreach developed malware integrated within Palo Alto Networks Cortex XDR, exploiting its ransomware protection feature.
Deactivating Cortex XDR via repair function
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
Process Mockingjay: Echoing RWX In Userland To Achieve Code Execution
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
ChatGPT creates mutating malware that evades detection by EDR
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.
Terminator antivirus killer is a vulnerable Windows driver in disguise
A threat actor known as Spyboy is promoting a Windows defense evasion tool called
2023-05-31 // SITUATIONAL AWARENESS // Spyboy Defense Evasion Tool Advertised Online
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).
EDR bypassing via memory manipulation techniques | WithSecure™ Labs
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. PDF Document

Following the Scent of TrickGate: 6-Year-Old Packer Used to Deploy the Most Wanted Malware
- Initially observed in July 2016, TrickGate is a shellcode-based packer offered as a service to hide malware from EDRs and antivirus programs. * Over the last 6 years, TrickGate was used to deploy the top members of the “Most Wanted Malware” list, such as Cerber, Trickbot, Maze, Emotet, REvil, Cobalt Strike, AZORult, Formbook, AgentTesla and more. * TrickGate managed to stay under the radar for years because it is transformative – it undergoes changes periodically. This characteristic caused the research community to identify it by numerous attributes and names. * While the packer’s wrapper changed over time, the main building blocks within TrickGate shellcode are still in use today. * Check Point Threat Emulation successfully detects and blocks the TrickGate packer.

EDR: Detections, Bypassess and other Shenanigans
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.
Cyberattaque : comment Caen a évité le pire grâce à l’EDR d’HarfangLab
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.
