Researchers Unveil New Linux Malware Linked to Chinese Hackers
2021-03-10 08:31

Cybersecurity researchers on Wednesday shed light on a new sophisticated backdoor targeting Linux endpoints and servers that's believed to be the work of Chinese nation-state actors. RedXOR's name comes from the fact that it encodes its network data with a scheme based on XOR, and that it's compiled with a legacy GCC compiler on an old release of Red Hat Enterprise Linux, suggesting that the malware is deployed in targeted attacks against legacy Linux systems.
