Cybercriminals from TeamPCP have escalated their attacks by compromising the legitimate Telnyx Python package on PyPI, affecting versions 4.87.1 and 4.87.2. The attackers gained access by stealing a maintainer's credentials, then injected malware that steals SSH private keys and bash history files from developers' systems. Unlike typical typosquatting attacks, this breach targeted an official, trusted package used by the Telnyx cloud communications platform. The malicious code executes automatically during installation, making it particularly dangerous for developers and automated systems. Socket and Endor Labs researchers discovered the attack on March 27, noting that TeamPCP has recently partnered with Vect ransomware group. Organizations should immediately audit their systems and rotate any exposed credentials. **Source:** [Infosecurity Magazine](https://www.infosecurity-magazine.com/news/teampcp-targets-telnyx-pypi-package/)
