Malicious code in timmytuffknuckles6 (npm)
--- _-= Per source details. Do not edit below this line.=-_ ## Source: amazon-inspector (22ef6fa6c2b9f80d6a1f79e532a9d9ea083a1c662bc834d118879ba630842b0c) This package is not a Node.js library. `package.json` declares `"main": "sw.js"`, a Service Worker that calls `importScripts('./8cfc2/hgshm.js')` — an API that does not exist in Node, so `require('timmytuffknuckles6')` throws immediately and the bundled obfuscated assets never execute on the installer's machine. The tarball contents are a school-unblocker / bare-mux web proxy bundle (index.html, multiple obfuscated `assets/*.js` files, WASM) wrapped in a `Riverbend Tutoring` cover page that, when served and visited in a browser, loads third-party scripts and opens popunders to external sites. There are no `preinstall`/`install`/`postinstall` lifecycle scripts, and no top-level Node-reachable code path that runs on install or require. The repository also ships `auto-publish.sh`, an author-run loop that rewrites `package.json.name` to `timmytuffknuckles1`..`timmytuffknuckles10` and republishes the same payload under each name, polluting the npm namespace with ten clones. The script is not a lifecycle hook and does not run on install. The heavy obfuscation in `assets/*.js` is consistent with the Ultraviolet/bare-mux proxy framework these projects use, not with installer-side harm. Routing to human review because the package is registry-misuse (proxy webapp masquerading as an npm library, plus deliberate ten-name namespace squatting) even though it does not attack installers. ## Source: ghsa-malware (040a672027041512418b9d898bcf26a02f2fe75f50d918b546a3283c87ffd9ee) 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.
AI Analysis
Technical Summary
The 'timmytuffknuckles6' package in the npm ecosystem is identified as malicious software. Any system with this package installed should be considered fully compromised, as the package grants an attacker full control over the system. The advisory warns that simply removing the package may not remove all resulting malware. There is no CVSS score or detailed technical vulnerability data available. No known exploits in the wild have been reported. No patch or remediation is provided, as this is a malicious package rather than a vulnerability in legitimate software.
Potential Impact
Full system compromise on any computer with the package installed. All stored secrets and keys on the affected system are at risk and must be rotated immediately. The presence of this package indicates a severe security breach.
Mitigation Recommendations
Remove the 'timmytuffknuckles6' package immediately from all affected systems. Rotate all secrets, keys, and credentials stored on the compromised computer from a different, secure system. Because full control may have been given to an attacker, further forensic analysis and system restoration from clean backups are recommended. There is no official patch or fix since this is a malicious package. Prevention includes avoiding installation of untrusted or suspicious npm packages.
