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.

On `require()`, `index.js` prints a banner derived from `os.platform()` and `os.hostname()` and then calls `process.exit(0)` at line 42, which terminates any host process that imports it. The package's own metadata (package.json description) declares the upload as a security-research proof-of-concept squat for an MSRC bug-bounty report. There is no network I/O, no shell execution, no credential or filesystem read, and no install-time lifecycle hook — the only installer-side effect is the abrupt process termination on import, which would break a build that mistakenly resolves this name instead of `@vscode/test-web`. Name-confusion risk is real but intent appears non-malicious; routing for human adjudication.\n\nAny 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.","ecosystems":["npm"],"exploits":{"exploitdb":null,"first_seen":null,"github_poc":null,"max_poc_stars":null,"metasploit":null,"nuclei":null,"refs":[],"tier":null},"has_fix":false,"headline":"Malicious code in vscode-test-web (npm)","id":"MAL-2026-6361","indexable":true,"kev":null,"kind":"malicious","links":{"ecosystem":"npm","product":null,"products":[],"type":null,"year":"2026"},"n_packages":1,"n_references":null,"packages":[{"ecosystem":"npm","fixed":[],"introduced":["0"],"last_affected":[],"package":"vscode-test-web","purl":"pkg:npm/vscode-test-web","source":"MAL-2026-6361"}],"products":null,"published":"2026-06-24","related":[],"sources":[{"class":"attribution","licence":"Apache-2.0","name":"OpenSSF Malicious Packages","prefix":"MAL"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":null,"updated":null,"vendors":null},"summary":null,"url":"https://insights.sbomify.com/MAL-2026-6361/"}
