MAL-2026-10389 Malicious code in timmytuffknuckles6 (npm)

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.

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.
