- offensive-supply-chainSnailSploit/Claude-RedComprehensive offensive methodology for software supply chain attacks covering the full kill chain from reconnaissance through exploitation. Addresses dependency confusion across npm, PyPI, and NuGet ecosystems where internal registry override allows an attacker to inject malicious packages that shadow private dependencies.

mvschwarz/openrig
OtherUpdated 15 hours ago
From the author
Use when changing a rig while it is alive — `rig grow` / `rig expand` / `rig shrink` / `rig launch` / `rig remove` / `rig discover` / `rig bind` / `rig adopt` / `rig attach`. Covers the 4 failure modes (newly created seat lacks queue/startup/role; edges and permissions not updated; adopt/bind succeeds at tmux but not OpenRig identity; shrink/remove leaves stale topology references) and the rule that mutation must work while the rig is active, not just in clean fixtures.
