**The Hidden Danger in Your Python Libraries: How a Rogue Package Used Audio Files to Steal Your Data**

In a sophisticated supply chain attack, cybersecurity researchers have uncovered a malicious version of the popular Telnyx Python library lurking on PyPI, the official Python Package Index. This rogue package cleverly disguises itself as a legitimate update, but instead of providing useful functionality, it unleashes a credential-stealing malware payload hidden within an ordinary WAV audio file—a tactic that makes detection remarkably difficult.
