Telnyx Python SDK Compromised on PyPI With Malware Hidden in WAV Audio Files
The Telnyx Python SDK on PyPI was compromised in a sophisticated supply chain attack that used WAV audio steganography to deliver malware. Malicious versions 4.87.1 and 4.87.2, uploaded by threat actor TeamPCP, executed arbitrary code on import and hid their payloads within the frame metadata of audio files.
