A Mysterious Grey-Hat Is Patching People's Outdated MikroTik Routers (zdnet.com)
An anonymous reader quotes a report from ZDNet: A Russian-speaking grey-hat hacker is breaking into people's MikroTik routers and patching devices so they can't be abused by cryptojackers, botnet herders, or other cyber-criminals, ZDNet has learned. The hacker, who goes by the name of Alexey and says he works as a server administrator, claims to have disinfected over 100,000 MikroTik routers already. "I added firewall rules that blocked access to the router from outside the local network," Alexey said. "In the comments, I wrote information about the vulnerability and left the address of the @router_os Telegram channel, where it was possible for them to ask questions." But despite adjusting firewall settings for over 100,000 users, Alexey says that only 50 users reached out via Telegram. A few said "thanks," but most were outraged. The vigilante server administrator says he's been only fixing routers that have not been patched by their owners against a MikroTik vulnerability that came to light in late April.
..but the sysadmin they deserve?
Regardless, I approve of this. Bravo, Sir.
This is the Right Thing To Do! So many times the Goody Two-Shoes so called "white hats" take out the botnets but rather that do this and patch the hacked machines, they just try to disable the current botnet. And surprise, surprise within a few months all the hacked machines are back in a new botnet, more fault tolerant botnet.
It's almost like these researchers realize that doing what this unsung hero did would hurt there job security. We should all celebrate this Russian hero. We need more like him.
I'll say it plainly, if you do not maintain your devices then anyone should be free to brick them.
I'll say it plainly, if you do not lock every single door and bolt down your windows then anyone should be free to steal your stuff.
I'll say it plainly, if you do not lock your car then anyone should be free to steal it.
I'll say it plainly, if you do not hold onto your phone every second you are out then anyone should be free to steal it.
Theft is not the same thing as breaking and entering so those are bad analogies. In this case, he fixed the issue you couldn't be bothered to fix for the sake of everyone else. It's still breaking and entering, but more like a neighbor breaking in to shut the gas off before your house destroys the neighborhood. I'd look at it as a favor...then I'd wipe the device and reflash and/or replace as necessary.
You should reset and update your router anyways. Just because this guy didn't install malware, it doesn't mean nobody else did.
Besides, if this guy didn't get to you, then you would've never noticed your router is vulnerable and the black hats would've had all the time in the world to do damage. But since he did, at least you know there is a problem and can do something about it.
