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: 53dc53db0f88fbd6b7c2fc00020bbcdaf3646d85 Marker: global['!']='8-113-2' 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/nomeyy/dev-test/pull/115.
