GitHub repository carrying the DPRK-linked PolinRider malware kit: obfuscated JavaScript disguised as a font/build-config file (postcss.config.js) that executes with Node when the project is opened or built, delivering a backdoor/infostealer chain. Malicious payload found in: postcss.config.js Commit: 0809889006da4bf9502623557d21179374317b5e Marker: global['!']='9-0013-4' Payload: obfuscated single-line PolinRider loader (DPRK-attributed) appended to a build config file after leading whitespace, so it runs whenever the project's dev/build tooling loads the config. Fork used to submit malicious PR(s) upstream: https://github.com/TheM1N9/builders-center/pull/4.
