There is a guy named Alexy who has patched a vulnerability in over 100,000 MicroTik routers. These routers are loved by hackers who can get at user passwords and load up things like bitcoin mining software onto them.

Alexy is, without permission, fixing the security holes in routers, but at the same time is making lots of people angry because they don’t want anyone logging into their equipment.

This is an example of “ethical hacking” where good people use their skills to address internet problems. The trouble is, Alexy could go to jail because technically he is breaking the law when he logs into the infected routers.
