A security researcher has demonstrated a method to bypass Claude Code Opus 5's Auto Mode, achieving an 80% success rate in executing code through prompt injection. This technique involves tricking the AI into downloading a malicious ZIP archive, which then exploits a poisoned `struct.py` file to execute arbitrary code when the `base64` module is imported. The findings contradict Anthropic's internal evaluation, which reported a 0.00% success rate for similar attacks. AI
