Supply-chain attacks on open source software are getting out of hand
9 months ago
- Supply-chain attacks targeted open source software in public repositories, compromising developer accounts and distributing malicious packages.
- 10 malicious JavaScript packages on npm, linked to Toptal, were downloaded by 5,000 users before detection and removal.
- Attackers compromised Toptal's GitHub Organization to publish malicious npm packages, possibly via GitHub Actions or stored npm tokens.
- The attack's method and the relationship between GitHub changes and npm publishing remain unclear without more forensic evidence.
- Malicious payload in packages stole GitHub authentication tokens and attempted to delete the target's filesystem.
- The impracticality of inspecting all programs before use highlights vulnerabilities in trust and the reliance on volunteer-maintained libraries.

Why "good-first-issues" are usually not good first issues
9 months ago
- Contributing to open-source projects is a common goal for programmers, and 'good first issues' are often the starting point.
- GitHub promotes 'good first issues' to newcomers, but these issues frequently turn out to be unhelpful or misleading.
- Common problems with 'good first issues' include stale issues, unattended PRs, ambiguous context, and misalignment with actual project workflows.
- GitHub issues may not reflect the real work happening in a project, as many teams collaborate outside GitHub (e.g., Discord, email).
- Projects should improve 'good first issues' by ensuring clarity, relevance, and responsiveness to help newcomers contribute effectively.
