The most technically interesting aspect involves steganography: malware hidden inside valid WAV audio files and PNG images, decoded via XOR to drop payloads. The analysis also covers a Python .pth file persistence trick, ETW patching to evade EDR telemetry, and C2 communication disguised with lookalike domains. Mitigation advice focuses on least-privilege GitHub Actions tokens, zero-trust principles, and regular credential rotation. ## Full article daily.dev links to this article rather than hosting it.
