Every version was published to cause harm.\n\nTask:\n1. Search this repository's dependency manifests and lockfiles for the package, including transitive dependencies.\n2. If it is present, remove it, regenerate the lockfile with the project's package manager, and replace whatever it was used for.\n3. List any CI runners, developer machines or containers that installed it, so their secrets can be rotated.\n4. If the package is not used anywhere, say so and change nothing.\n\nReference: https://insights.sbomify.com/MAL-2026-5916/ (Markdown: https://insights.sbomify.com/MAL-2026-5916/index.md)","id":"MAL-2026-5916","markdown":"https://insights.sbomify.com/MAL-2026-5916/index.md","name":"MAL-2026-5916","record":{"aliases":["GHSA-2gj2-9868-32pf"],"analysis":null,"analysis_generated_by":null,"assigner":null,"cpe":[],"cvss":{"score":null,"severity":null,"source":null,"vector":null,"version":null},"cwes":[],"description":"The tarball is not a Node library. `package.json` declares `main: sw.js` with description `\"package\"` and an empty author; `sw.js` is a browser ServiceWorker (`importScripts('./8cfc2/hgshm.js')`, `self.skipWaiting()`, `self.clients`, fetch interception) that has no meaning when consumed via `require('nottuff25')` in Node. The shipped static site bundles the Mercury Workshop Scramjet web proxy plus bare-mux, branded as \"Riverbend Tutoring\" while pointing `og:url` at `21baseballacademy.com` — a misrepresentation of what the npm name advertises. The tarball also ships `auto-publish.sh`, a bash script with a hardcoded list of 95+ sibling package names (nottuff1-30, ishowfeet1-20, imillegal1-5, abuden*, ratelimitsucks*) that rewrites `package.json` and runs `npm publish --silent` in a loop — the attacker's own mass-publication pipeline shipped inside the artifact, with the current package name `nottuff25` appearing as a literal entry in that list. `index.html` additionally registers click/keydown/touchstart listeners that open `https://abdct.com/` as a popunder on first interaction (browser-side adware, not installer-side). No install/require-time exfil, RCE, or credential theft is present, but this is a coordinated namespace-pollution campaign and the package misrepresents itself to npm consumers.\n\nAny computer that has this package installed or running should be considered fully compromised.
