Hacker News ThreatsDay roundup: Defender BTR.sys driver abuse, DoJ charges 17 Mabna Institute members over IRGC-linked intrusions, Grandoreiro sideloading, OpenAI monitoring.
Check Point researchers showed Microsoft's signed Defender Boot-Time Removal driver (BTR.sys) can be repurposed as a universal kernel operation engine to bypass endpoint security without BYOVD. The DoJ charged 17 members of Iran's Mabna Institute, which on behalf of the IRGC stole over 31 TB of academic data from 144 US universities and compromised roughly 8,000 of 100,000 targeted professor accounts; the State Department offered a $10 million reward for five defendants. Separately, Acronis tracked a Grandoreiro campaign abusing DLL sideloading in the Duplicate Files Finder app across Latin America and Spain, while ErrTraffic ClickFix campaigns deliver Cruciferra (BYOVD) and Remus Stealer. OpenAI also previewed Private Safety Processing, a privacy-centric approach to monitoring model misuse without retaining customer content.

Kimwolf v7 Android Botnet Makes HTTP/2 DDoS Traffic Look Like Legitimate Browsing
New Kimwolf v7 Android botnet adds HTTP/2 DDoS floods with Chrome fingerprints and takedown-resistant ENS/Tor C2.
Palo Alto Networks Unit 42 discovered Kimwolf v7, an evolution of the Kimwolf/AISURU Android and IoT botnet first tracked in February 2026. The new version performs HTTP/2 floods mimicking Chrome browser fingerprints and uses Ethereum Name Service, Tor hidden services, and a local proxy for resilient C2. The botnet targets Android TV boxes via ADB on port 5555 and offloads propagation to an external loader.
