It decodes a base64-encoded Ruby payload and runs it via eval inside a detached fork (Process.setsid, randomized sleep of 1200+rand(1200) seconds) so execution survives the install process. The decoded payload opens a TCP socket to the hardcoded bare IP 45.138.12.177:8089 and bridges it to /bin/sh, giving an interactive remote shell on the installer's host. Execution is gated by anti-analysis checks that skip CI runners, ephemeral/sandbox hosts, generated usernames, analysis paths, and low-uptime machines, firing only when developer artifacts such as ~/.ssh, ~/.gitconfig, ~/.npmrc, ~/.gem/credentials, or ~/.bundle are present on the host. Package identity is inconsistent: the gem is named seed-phrase-validator, the README is titled bitcoin-rpc-lite, and the makefile target is bitcoin_rpc_lite_native, with no matching native sources in the tree.\n\n---\n\nCredit: OpenSSF ([source](https://github.com/ossf/malicious-packages/","public_affected_ranges":["= 0.9.1"]}],"null_published_at":"2026-10-31T22:13:44.207Z","source_updated_at":"2026-10-14T00:31:19.000Z","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"}
