Malicious code in ach-detail (npm)
The npm package 'ach-detail' version 99.0.2 contains malicious code in its preinstall script that automatically executes during installation. This script collects detailed host identity information, including hostname, OS details, architecture, user identity, network IP addresses, Node.js version, and package identity. The collected data is sent to a hardcoded author-controlled endpoint via HTTPS, with a fallback to plaintext HTTP, exposing sensitive information on the network. The data collection and transmission occur without user consent or configuration options. No official patch or remediation guidance is provided.
AI Analysis
Technical Summary
The 'ach-detail' npm package version 99.0.2 includes a malicious preinstall.js script that runs automatically during npm install. It gathers host system identifiers such as os.hostname(), OS type/version/release, CPU architecture, output of 'whoami', non-internal IPv4 addresses, Node.js version, and package identity. This information is sent as a JSON payload to a hardcoded endpoint at https://callback.kuldeep.io/beacon, with an insecure HTTP fallback if HTTPS fails. The endpoint is not configurable by the installer, and the installer does not opt in to this data collection. The fallback to plaintext HTTP exposes the collected data to network interception. The script's self-labeling as a proof-of-concept or bug bounty placeholder is controlled by the package author and does not imply installer consent.
Potential Impact
Sensitive host information is exfiltrated without user consent, potentially exposing system identity, user information, network details, and environment specifics to an attacker-controlled server. The fallback to plaintext HTTP further risks interception of this data by network attackers. This compromises user privacy and may aid further targeted attacks or reconnaissance.
Mitigation Recommendations
No official patch or remediation is currently available. Users should avoid installing version 99.0.2 of the 'ach-detail' package. Monitor vendor advisories for updates or patches. Consider auditing npm packages before installation to detect unauthorized scripts.
