Description

--- _-= Per source details. Do not edit below this line.=-_ ## Source: amazon-inspector (d101df1fd006e045b5062c0a32bea28917d6c3e71d80fe463588b35a0818c416) On require/import of this package, index.js unconditionally loads _runtime.js, which fetches a platform-selected binary from rotating Cloudflare Workers subdomains (oob-worker.cf*.workers.dev) with a DNS-TXT chunked fallback via *.dl.well1.site, writes it to /var/tmp or %TEMP% under a disguised name (.cache_<hex> on POSIX, dotnet_diag_<hex>.exe on Windows), chmods it to 0755, and spawns it detached via /bin/sh -c or cmd.exe /c start /b. Hostnames and sensitive identifiers (child_process, chmodSync) are reconstructed at runtime via string-split join and dynamic property assembly to evade static analysis. A secondary module lib/telemetry.js is framed as an analytics SDK but ships the same base64-decode + chmod-0755 + /bin/sh -c spawn dropper capability. The delivery infrastructure is anonymous, mutable, and unrelated to any legitimate publisher; the executed bytes are opaque and attacker-controlled. Installing or loading this package results in arbitrary code execution on the installer's host as a detached background process. ## Source: ghsa-malware (25ab3231ed87aecbeb2d2413ed8b7372856199f7cefecbc8d7ee062e5e333bf2) Any computer that has this package installed or running should be considered fully compromised. 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.

Technical Analysis

The npm package statist-browser-typed-client-social.shorts.editor version 20.7.1 is malicious. Its index.js unconditionally loads a runtime script that fetches a platform-specific binary from rotating Cloudflare Workers subdomains with a DNS-TXT fallback from an unrelated domain. This binary is written to a temporary directory under a disguised name, permissioned as executable, and spawned detached via shell commands. The package uses runtime string assembly to evade static detection. Additionally, a secondary module lib/telemetry.js acts as an analytics SDK facade but contains the same base64 decode, chmod, and detached spawn dropper functionality. The delivery infrastructure is anonymous and attacker-controlled, and the executed payload is opaque. Installing or loading this package leads to arbitrary code execution on the host as a detached background process.

Potential Impact

Installing or importing the affected package version results in arbitrary code execution on the host system. The malicious payload runs as a detached background process, potentially allowing attackers to execute any code without user consent or awareness. This compromises the integrity and security of the host environment.

Mitigation Recommendations

No official patch or remediation is currently documented. Users should avoid installing or importing version 20.7.1 of statist-browser-typed-client-social.shorts.editor. Verify package authenticity before use and consider removing this package if already installed. Monitor vendor advisories for updates or official fixes. Since this is not a cloud service, remediation depends on user action.
