Malicious code in dolyame-ui-react-wrapper (npm)
The npm package dolyame-ui-react-wrapper version 35.4.2 contains malicious code that executes upon module load. It reconstructs obfuscated hostnames to download platform-specific binaries from suspicious domains, writes these binaries to temporary directories under disguised filenames, sets executable permissions, and executes them detached from the main process. The package masquerades as a UI React wrapper unrelated to its actual malicious behavior.
AI Analysis
Technical Summary
The dolyame-ui-react-wrapper npm package version 35.4.2 includes a malicious setup routine triggered at module load. This routine reconstructs obfuscated mirror hostnames and DNS-discovery domains to download platform-specific binaries via HTTPS. The binaries are saved to temporary directories with disguised names (e.g., '.cache_<hex>', 'dotnet_diag_<hex>.exe'), permissions are set to executable, and the binaries are spawned detached using shell commands. The package name and string obfuscation are intended to evade detection and scanners.
Potential Impact
This malicious package can lead to unauthorized code execution on systems that install and run it. The downloaded binaries could perform arbitrary actions depending on their payload, potentially compromising system integrity and confidentiality. The disguised filenames and obfuscation techniques increase the difficulty of detection and mitigation.
Mitigation Recommendations
No official patch or remediation is currently documented. Users should avoid installing or using version 35.4.2 of dolyame-ui-react-wrapper. Remove the package if already installed and scan systems for the presence of the described binaries in temporary directories. Monitor for suspicious network connections to the indicated domains. Check vendor advisories or npm security advisories for updates or official guidance.
