Hackers compromised the Telnyx Python SDK on PyPI and hid malware inside .wav sound files - disguised as audio to bypass security scanners. Versions 4.87.1 and 4.87.2 were poisoned - just importing the package triggers the attack. It grabs SSH keys, cloud credentials, and can hijack Kubernetes clusters. The malicious versions were live for about 6 hours before PyPI quarantined them.
