Description

--- _-= Per source details. Do not edit below this line.=-_ ## Source: amazon-inspector (342d7a44db99769023685647376a6042d5a9b345c281826484c9d88561f245ca) Package is not a Node library — `package.json` declares `main: sw.js`, a browser Service Worker whose first line calls `importScripts('./8cfc2/hgshm.js')`. `importScripts` is undefined in Node, so `require('timmytuffknuckles9')` throws immediately. No `preinstall`, `install`, `postinstall`, or `prepare` lifecycle scripts are declared, so `npm install` does not execute any package code. The tarball contains a bundled web app (a Lucide-style web proxy/unblocker) with heavily obfuscated JS assets and a popup ad redirect to `abdct.com`, but those run only inside a browser that loads the Service Worker — not on the developer's machine. Separately, the tarball ships `auto-publish.sh`, a helper that rewrites `package.json.name` in a loop to `timmytuffknuckles1` through `timmytuffknuckles10` and runs `npm publish` for each, evidence that the publisher is using npm as a hosting/CDN-style namespace and mass-publishing near-duplicate package names. This script is not wired to any lifecycle hook and does not run on install. Routing to human review for registry-hygiene assessment (off-purpose use of npm + namespace spam + heavily obfuscated bundled assets) rather than installer-harm. ## Source: ghsa-malware (494c159c67f9b2488892ee0098bf3e008466c212b13b48e132afa7e0ab6b8045) 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 'timmytuffknuckles9' package in the npm ecosystem is identified as containing malicious code capable of fully compromising an affected system. According to the source advisory, any computer with this package installed or running should be considered fully compromised, with potential unauthorized control granted to an outside entity. The advisory warns that simply removing the package may not remove all malicious software introduced by it. No CVSS score or detailed technical exploit information is provided. No affected versions are specified.

Potential Impact

Full system compromise on any computer with the package installed or running. Potential unauthorized access to all secrets and keys stored on the system. The attacker may maintain persistent control beyond removal of the package.

Mitigation Recommendations

Remove the 'timmytuffknuckles9' package immediately from all affected systems. Rotate all secrets and keys stored on the compromised systems from a different, trusted computer. Because full control may have been granted to an attacker, further forensic analysis and remediation may be necessary. No official patch or fix is available; mitigation relies on removal and secret rotation.
