The decoded code opens a TCP connection to 45.138.12.177:8089 and bridges it to /bin/sh, giving the remote operator an interactive shell on the installer's machine. Execution is gated by sandbox/CI-evasion checks: it skips if common CI environment variables are set, if the hostname or username matches sandbox/analyst patterns (uvm/firecracker/sandbox/vagrant/tester/analys/scanner), if the working directory is under /tmp, /opt/rubygems, or /workspace, if /proc/uptime is under 1800 seconds, and it additionally requires developer artifacts such as ~/.ssh, ~/.gitconfig, ~/.gem/credentials, ~/.npmrc, or ~/.bundle to be present.
