Backdoored Telnyx PyPI Package Drops WAV-Stego Malware
⚠️A backdoored release of the Telnyx Python SDK on PyPI was used to deploy credential-stealing malware hidden inside WAV audio files. Security firms Aikido, Socket, and Endor Labs attribute the tampering to TeamPCP, which published versions 4.87.1 and 4.87.2; the latter contained a functioning payload. The malicious code executes on import from telnyx/_client.py and uses steganography to XOR-decode a WAV-hosted second stage that harvests SSH keys, cloud tokens, wallets, environment variables, and Kubernetes secrets. Developers are advised to revert to Telnyx 4.87.0 and treat any systems importing the affected releases as compromised.
