Malicious code in @innocarpe/deepseek-build (npm)
The npm package @innocarpe/deepseek-build version 1.0.0 contains malicious code in its postinstall script that executes automatically upon installation. This script uses Node.js child_process to send POST requests containing environment and host identifier data, effectively performing install-time reconnaissance on the host system. This behavior is not part of any documented build process and represents unauthorized data exfiltration during package installation.
AI Analysis
Technical Summary
The npm package @innocarpe/deepseek-build version 1.0.0 includes a postinstall lifecycle script (scripts/postinstall.js) that requires the child_process module and issues outbound POST requests during installation. These requests carry environment variables and host identifiers, indicating the script performs credential or host reconnaissance at install time. This automatic network activity is triggered by the package's lifecycle hook and is not documented as a legitimate build step, classifying it as malicious code embedded in the package.
Potential Impact
Installing version 1.0.0 of @innocarpe/deepseek-build causes automatic outbound network communication that transmits environment and host identification data. This can lead to unauthorized disclosure of sensitive system information during package installation, potentially aiding attackers in further targeting or reconnaissance activities.
Mitigation Recommendations
No official patch or remediation is currently documented for this issue. Users should avoid installing version 1.0.0 of @innocarpe/deepseek-build. Monitor vendor advisories for updates or official fixes. Consider auditing package scripts before installation to detect unexpected network activity.
