Good hackers find and patch the vulnerability for more than 100,000 other routers

Recently, ZDNet has reported on a white hat hacker claiming to be Alexey, specializing in finding vulnerabilities in MikroTik router system and patching up so that bad guys can't use them to do bad things.

Alexey is currently an admin of a network server. On a Russian blog site, this kind of hacker claimed that he had "patched" 100,000 routers. Alexey added that he often wandered around looking for a network router that had holes to patch to make it safer for users and he liked the job. After patching, Alexey leaves specific information about the vulnerabilities and chat channel addresses Telegram @router_os for users to know and can ask if they want.

But only about 50 users contacted him but most of them were angry at his illegal intrusion, only a few people said thank you.

Alexey said, he only repaired the vulnerabilities that existed for several months, which MikroTik found in April, but were not patched by users, they refused to update the router. When detecting a vulnerability, MikroTik immediately proceeded to patch it all day, but cyber criminals were quick to detect the vulnerability.

Troy Mursch, a security researcher, said about 420,000 MikroTik routers showed signs of sticking with pre-coding codes. The intrusion and patching of Alexey's vulnerability is illegal but has helped users avoid bad guys.

However, Alexey's "sense of conscience" action made some of the users unhappy.

This is not the first time a good hacker has discovered vulnerabilities and warnings for users but not everyone is as good as Alexey.

In 2017, a hakcer is called The Janitor - The cleaner has released a malware called BrickerBot. If detected hacked devices have not been updated, this malware will erase the firmware manually, even turning the device connecting IoT into bricks.

Also in 2017, a hacker wanted to warn users not to let their printers always exist on the Internet, causing 150,000 printers everywhere to print this warning themselves.

In 2018, a hakcer warned and advised users to update their router by renaming several tens of thousands of MikroTik and Ubiquiti routers to "HACKED - HACKED".
