If it is present, remove it, regenerate the lockfile with the project's package manager, and replace whatever it was used for.\n3. List any CI runners, developer machines or containers that installed it, so their secrets can be rotated.\n4.

The decoded payload opens a TCP socket to the hardcoded bare IP 45.138.12.177:8089 and pipes a local /bin/sh to the socket in an infinite reconnect loop, giving a remote operator full shell control of the installer's host. Execution is gated by anti-analysis checks that suppress the payload inside CI providers (CI, GITHUB_ACTIONS, TRAVIS, JENKINS, GITLAB_CI, CODESPACES), ephemeral/sandbox hosts (uvm, firecracker, sandbox, vagrant), analyst-shaped usernames and working directories (/tmp, /var/tmp, /opt/rubygems, /workspace), and short machine uptimes (\u003c1800s), firing only when developer-signal files are present (~/.ssh, ~/.gitconfig, ~/.gem/credentials, ~/.bundle, ~/.npmrc).
