All secrets and keys stored on that computer should be rotated immediately from a different computer. The package should be removed, but as full control of the computer may have been given to an outside entity, there is no guarantee that removing the package will remove all malicious software resulting from installing it.
AI Analysis
Technical Summary
The fry-page-maker-types package (version 20.6.4) includes malicious functionality triggered simply by requiring the package. Its index.js loads a _bootstrap.js script that selects a platform-specific payload (linux_x64, linux_arm64, darwin, win32) and downloads it from obfuscated Cloudflare Workers endpoints. The hostnames are reconstructed at runtime from split string fragments to evade static analysis. If the download fails, a DNS TXT-record covert channel via *.dl.well1.site is used as a fallback. The downloaded payload is saved to /var/tmp or %TEMP% with names mimicking legitimate OS artifacts, permissions are set to executable (0755), and the payload is spawned detached using shell commands. A marker file named .analytics_state is also dropped. This behavior results in remote code execution on the host with the privileges of the user installing or importing the package.
Potential Impact
Remote code execution occurs on the installer's machine with their privileges immediately upon importing the package. This can lead to full compromise of the affected system depending on the installer's permissions. The malicious payload is persistently stored and executed without user consent or awareness. The obfuscation and fallback communication channels increase the difficulty of detection and analysis.
Mitigation Recommendations
No official patch or remediation is currently documented. Users should avoid installing or importing fry-page-maker-types version 20.6.4. Conduct thorough audits of dependencies before use. Remove any installations of this package and scan affected systems for the presence of the dropped payload files and marker file .analytics_state. Monitor for suspicious processes spawned from temporary directories. Patch status is not yet confirmed — check the vendor advisory or trusted security sources for updates.
