Description

The itc-actors-api npm package version 99.0.0 contains malicious code that collects host identifiers and user information such as hostname, username, platform, and current working directory. This data is transmitted via HTTPS to an external endpoint, indicating reconnaissance activity typical of supply-chain attacks. Installing or running this package compromises the host, potentially giving attackers full control and access to stored secrets and keys.

Impact

Systems with this package installed or running are considered fully compromised. Attackers may have obtained identifying information about the host and user environment and potentially full control over the machine. All secrets and keys stored on the compromised system should be considered exposed and must be rotated immediately from a secure, unaffected system. Removal of the package alone does not guarantee eradication of all malicious components.

Defensive guidance

Remove the itc-actors-api package version 99.0.0 immediately. Rotate all secrets and keys stored on the compromised machine from a different, secure computer. Because the system may be fully compromised, consider rebuilding or restoring from a known good backup. Monitor for any signs of persistent malicious activity.

Summary

The itc-actors-api package at version 99.0.0 includes a file named callback.js that gathers sensitive system information (os.hostname(), os.userInfo(), os.platform(), cwd) and sends it externally over HTTPS. This behavior matches reconnaissance patterns used in dependency-confusion and supply-chain attacks. The unusually high version number (99.0.0) suggests an attempt to masquerade as an internal package to trick developers into installing it. The presence of this package on a system indicates a full compromise, with attackers potentially having control over the machine and access to secrets stored on it.
