Python Developers Beware: Clipper Malware Found in 450+ PyPI Packages!

Malicious actors have published more than 451 unique Python packages on the official Python Package Index (PyPI) repository in an attempt to infect developer systems with clipper malware. Software supply chain security company Phylum, which spotted the libraries, said the ongoing activity is a follow-up to a campaign that was initially disclosed in November 2022. The initial vector entails using

GitHub Breach: Hackers Stole Code-Signing Certificates for GitHub Desktop and Atom

GitHub on Monday disclosed that unknown threat actors managed to exfiltrate encrypted code signing certificates pertaining to some versions of GitHub Desktop for Mac and Atom apps. As a result, the company is taking the step of revoking the exposed certificates out of abundance of caution. The following versions of GitHub Desktop for Mac have been invalidated: 3.0.2, 3.0.3, 3.0.4, 3.0.5, 3.0.6,

GUAC - Aggregates Software Security Metadata Into A High Fidelity Graph Database

Note: GUAC is under active development - if you are interested in contributing, please look at contributor guide and the "express interest" issue

Graph for Understanding Artifact Composition (GUAC) aggregates software security metadata into a high fidelity graph database—normalizing entity identities and mapping standard relationships between them. Querying this graph can drive higher-level organizational outcomes such as audit, policy, risk management, and even developer assistance.

Conceptually, GUAC occupies the “aggregation and synthesis” layer of the software supply chain transparency logical model:

A few examples of questions answered by GUAC include:
