Malicious code in dolyame-ui-react-dom-wrapper (npm)
The npm package dolyame-ui-react-dom-wrapper version 35.8.9 contains malicious code that, when required, downloads and executes attacker-controlled binaries on the host system. The package fetches opaque binaries from multiple attacker-controlled domains, writes them to temporary directories with disguised filenames, sets executable permissions, and runs them detached from the main process. This behavior occurs via obfuscated runtime string assembly to evade static detection. Any installer or user requiring this package risks executing arbitrary code with their privileges.
AI Analysis
Technical Summary
The dolyame-ui-react-dom-wrapper npm package version 35.8.9 includes malicious functionality in its main entry (_helpers.js) and telemetry.js. It dynamically constructs domain names and sensitive API calls to evade static analysis, then downloads opaque binary payloads from attacker-controlled Cloudflare Worker subdomains and fallback domains. These binaries are saved to temporary directories under disguised names, made executable, and executed detached from the parent process using shell commands. This results in arbitrary code execution with the privileges of the user running the package. The malicious behavior is embedded in two parallel dropper chains within the package.
Potential Impact
Any user or system that installs or requires dolyame-ui-react-dom-wrapper version 35.8.9 will execute attacker-controlled binaries with their user privileges. This can lead to full compromise of the affected system, including unauthorized code execution, data theft, persistence, or further malware deployment. The attack leverages obfuscation to evade detection and executes without user consent beyond the package installation or usage.
Mitigation Recommendations
No official patch or remediation is currently documented. Users should immediately avoid installing or requiring dolyame-ui-react-dom-wrapper version 35.8.9. Remove the package from all projects and environments. Monitor for any execution of suspicious binaries named similarly to '.cache_<rnd>' or 'dotnet_diag_<rnd>.exe' in temporary directories. Consider scanning systems for presence of the malicious binaries and related processes. Check vendor advisories or trusted security sources for updates or official fixes.
