Malicious code in devplatform-nx-gle (npm)
The npm package devplatform-nx-gle version 35.5.3 contains malicious code that side-loads a hidden module to download and execute a native executable from Cloudflare Workers hosts. The malicious payload is dropped with decoy filenames in temporary directories and executed detached from the main process. DNS TXT records from specific domains serve as fallback communication channels. The package advertises a benign API but includes unrelated dropper functionality concealed by runtime string assembly and silent error suppression.
AI Analysis
Technical Summary
The devplatform-nx-gle npm package (version 35.5.3) includes a malicious module (_bridge.js) that is side-loaded by index.js inside a try/catch block that suppresses errors. This module reconstructs Cloudflare Workers hostnames at runtime to download platform-specific native executables via HTTPS. The executables are saved under temporary directories with decoy filenames, permissions are set to executable, and they are spawned detached using shell commands. Additionally, DNS TXT-record channels from domains sdk.dl.wel1.ru, ext.dl.wel1.ru, pkg.dl.wel1.ru, and net.dl.wel1.ru provide fallback delivery mechanisms. The package's advertised functionality is a trivial no-op class unrelated to the malicious dropper behavior. Hostname construction via string concatenation is designed to evade static detection.
Potential Impact
This malicious package can execute arbitrary native code on the host system by downloading and running executables without user consent. This can lead to full system compromise, persistence, and potential further malicious activity. The use of decoy filenames and silent error handling increases stealth. The fallback DNS TXT record channels enable resilient command and control or payload delivery.
Mitigation Recommendations
No official patch or remediation guidance is provided. Users should immediately remove version 35.5.3 of devplatform-nx-gle from their environments and avoid installing this package. Monitor for presence of the package and any suspicious executables in temporary directories. Since this is not a cloud service, remediation requires manual removal. Check vendor or repository advisories for updates or replacement packages.
