BTR Reforged: Weaponizing Defender’s Remediation Driver as a Kernel Operation Primitive

Check Point Research demonstrates how Microsoft Defender's remediation driver can be weaponized as a kernel-level primitive to execute arbitrary file and registry operations with Ring 0 privileges, bypassing the need for traditional exploits or memory corruption vulnerabilities. This technique leverages a signed, trusted security component to grant attackers powerful kernel capabilities without requiring vulnerability exploitation, presenting a novel attack surface within Windows Defender itself.

Encrypted Prompts Bypass AI Safety Guardrails in Grok and Gemini

Researchers have identified a new attack technique called Cryptographic Context Injection that encrypts malicious instructions to evade safety guardrails in AI models including Grok and Gemini. The method works by concealing harmful prompts until they are decrypted within a trusted execution environment, effectively bypassing existing content filtering mechanisms. This vulnerability highlights a novel attack vector against popular large language models that defenders should monitor.
