Threats Tagged 'pypi compromise'

A supply chain attack targeting the Microsoft DurableTask Python client compromised versions 1.4.1, 1.4.2, and 1.4.3 on PyPi. The threat actor gained access through a compromised GitHub account previously linked to attacks, using stolen credentials to dump GitHub secrets containing PyPi tokens. The evolved payload targets Linux systems, stealing credentials from AWS, Azure, GCP, Kubernetes, Vault, and password managers like Bitwarden and 1Password. It propagates via AWS SSM and Kubernetes lateral movement, limited to 5 targets per infected host. The payload scrapes shell history, bruteforces password managers, and establishes persistence through infection markers. Compromised packages were quarantined following analysis.

Xinference, an open-source distributed AI model inference framework, suffered a supply chain attack when attackers compromised PyPI release credentials of maintainers and published three malicious versions (2.6.0, 2.6.1, 2.6.2) on April 22, 2026. The malicious code, encoded in Base64 layers within __init__.py, executes automatically upon library installation or import, collecting cloud credentials, SSH keys, API tokens, database passwords, cryptocurrency wallets, and environment variables. The payload specifically targets AWS environments through metadata service exploitation and uploads stolen data to attacker-controlled infrastructure. The attack affects users who downloaded these versions from PyPI, which has over 680,000 total downloads. Attribution remains unclear as TeamPCP's name appears in the code but the group denies involvement, suggesting third-party impersonation.
