Campaign
Summary

Show ▼
A North Korean supply-chain campaign dubbed PolinRider is injecting obfuscated JavaScript into compromised GitHub repositories, exposing developers to staged malware delivery at scale. The operation has reached nearly 2,000 repositories, turning trusted configuration files into a malware distribution path. The chain delivers BeaverTail and then the InvisibleFerret backdoor, increasing the risk of credential theft and persistent access.
