Linux Hacker Exploits Researchers With Fake PoCs Posted to GitHub


By disseminating bogus proofs-of-concept (PoCs) containing Linux backdoors, one GitHub user was able to trick security researchers. PoCs are used by cybersecurity researchers to test and analyse vulnerabilities that are already known to the public. They are necessary and common, which may make it simpler for a bad one to get through.

The individual is no longer active on the site. At the time of detection, one of the two false PoCs had been forked 25 times; a second copy had been forked 20 times.
