The package name resembles @ngrx/component-store. The main entry index.js requires./helpers, which on module load assembles attacker-controlled hostnames via array-join concatenation (e.g. ["oob-worker.","cf99-9b3.workers.d","ev"].join("")) to reach oob-worker.cf99-9b3.workers.dev, oob-worker.cf103-070.workers.dev, and oob-worker.cf101-adf.workers.dev, with a DNS-TXT chunked base64 fallback under *.dl.wel1.ru. A platform-specific binary is fetched, written to /var/tmp or %TEMP% under a disguised name (.cache<hex> or dotnetdiag<hex>.exe), chmod 0755'd, and spawned detached via /bin/sh -c or cmd /c start /b. lib/telemetry.js hides dangerous API names by string concatenation (require("child_" + "process"), fs["chmod" + "Sync"]). The load-time fetch-and-execute of an opaque native executable from obfuscated hosts fires on any require() of this package.

Any computer that has this package installed or running should be considered fully compromised. All secrets and keys stored on that computer should be rotated immediately from a different computer. The package should be removed, but as full control of the computer may have been given to an outside entity, there is no guarantee that removing the package will remove all malicious software resulting from installing it.
