It also recursively walks the.minecraft directory reading.json/.txt/.cfg/.properties/.yml/.log files and matches their contents against JWT and Bearer-token regexes. The collected credentials are combined with os.hostname(), os.userInfo().username, and os.platform() and POSTed via HTTPS to a hardcoded Discord webhook (discord.com/api/webhooks/1554065488726990909/...). No functionality matching the package name is present; the sole effect of installing the package is credential theft against the installer.\n\n---\n\nCredit: OpenSSF (source)","public_affected_ranges":["= 1.0.0"]}],"null_published_at":"2026-11-01T01:45:40.753Z","source_updated_at":"2026-09-29T00:31:31.000Z","source_disclosed_at":"2026-09-29T00:31:23.000Z","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":"2026-11-01T00:58:30.605Z"}],"next_cursor":null,"snapshot_revision":"42594"}
