Unit 42 identified TuxBot v3 Evolution, a modular multi-architecture IoT botnet framework whose developer relied heavily on an LLM to generate C bot and Go C2 server code. The LLM-assisted development introduced reproducible bugs (an XOR key mismatch, an exploit VM file-magic mismatch, and a hallucinated Argon2id implementation that silently uses PBKDF2) that break several fallback C2 channels and exploit delivery mechanisms, while core scanning, encrypted C2, persistence, and DDoS capabilities remain functional. Infrastructure pivoting links TuxBot's dropper and C2 servers to the broader Keksec/Kaitori and AISURU botnet ecosystems, and researchers assess a fixed, fully operational variant is a likely near-term threat.
