Iranian Hackers Deploy Cavern C2 Framework Against Israeli Sectors
In early 2026, an Iranian state-sponsored hacking group known as Cavern Manticore targeted Israeli government and IT sectors using a sophisticated modular command-and-control (C2) framework called Cavern. This framework, built on a .NET foundation with multiple compilation formats, enabled the attackers to execute DLL side-loading through SysAid's software update feature, leading to the deployment of various modules for reconnaissance, data theft, and lateral movement. The attack chain involved the execution of a trojanized DLL ('uxtheme.dll') containing the Cavern Agent, which then loaded additional modules to contact the C2 server and fetch further post-exploitation tools. ([research.checkpoint.com](https://research.checkpoint.com/2026/cavern-manticore-exposing-iran-linked-modular-c2-framework/?utm_source=openai)) The incident underscores the evolving tactics of Iranian threat actors, who are increasingly leveraging modular and adaptable toolsets to enhance their cyber espionage capabilities. The use of such frameworks allows for tailored deployments based on victim profiles, reducing forensic visibility and ensuring persistent access.

SkillCloak: Unveiling the Evasion of Malicious AI Skills
In July 2026, researchers from the Hong Kong University of Science and Technology unveiled 'SkillCloak,' a technique enabling malicious AI agent skills to evade static scanners through self-extracting packing methods. By embedding malicious payloads within directories typically ignored by scanners, such as .git/, and reconstructing them during execution, SkillCloak achieved over 90% evasion rates across eight tested scanners. This method allows attackers to distribute harmful skills that can steal credentials, exfiltrate source code, or install backdoors, all while appearing benign during initial scans. ([thehackernews.com](https://thehackernews.com/2026/07/new-skillcloak-technique-lets-malicious.html?utm_source=openai)) The study underscores a critical vulnerability in current AI agent ecosystems, where static analysis tools fail to detect dynamically concealed threats. This highlights the urgent need for enhanced runtime behavior monitoring and the development of more robust detection mechanisms to safeguard against sophisticated evasion tactics.
