The README advertises an unrelated package name (`bitcoin-rpc-lite`), confirming the gem's declared purpose is a cover. extconf.rb base64-decodes a Ruby payload and eval's it inside a forked/detached process; the decoded payload opens a TCPSocket to the hardcoded host 45.138.12.177 on port 8089 and bridges a /bin/sh session over the socket via IO.popen and IO.copy_stream, granting the operator an interactive reverse shell on the installer's machine. Execution is gated by anti-analysis checks: CI environment variables, hostname patterns (uvm/firecracker/sandbox/vagrant), generated usernames, analysis working directories (/opt/rubygems, /tmp, /workspace), and short /proc/uptime values all suppress the payload, which fires only when developer artifacts such as ~/.ssh, ~/.gitconfig, and ~/.gem/credentials are present on the host.\n\n---\n\nCredit: [OpenSSF](https://github.com/ossf/malicious-pa","public_affected_ranges":["= 0.9.1"]}],"null_published_at":"2026-10-31T22:13:39.953Z","source_updated_at":"2026-10-14T00:31:18.000Z","source_disclosed_at":"2026-10-11T15:31:13.000Z","is_synthetic_fixture":false,"null_last_reviewed_at":null,"public_change_summary":"First indexed by Null; source disclosure date is shown separately.","null_first_observed_at":"2026-10-31T22:06:23.261Z"}],"next_cursor":null,"snapshot_revision":"42594"}
