Mikrotik forgot HIS password!

Fri May 18, 2018 10:04 am

I've managing a bunch of Mikrotik routers and one of them forgot his password/username... no, not me! something happened with the device and I can not login anymore.
Device is Mikrotik RouterBOARD 1100AHx4 (there was a problem once with the device it's just "forgot" the DHCP server) and now I can not access to it..

What could happened.. how can I access to it without reseting? If it is really necessary I can go to the device (few hours trip) but reset is not an option.

If it's helps there is a backup but inside the device it was not downloaded from the device when it was configured finally.

No default user left, custom username and strong password used.

Depending on the RouterOS version you have, your device may have been hijacked by exploiting this or other vulnerability.

So it could be that the device has not forgotten the password but that the malware has changed it.
Instead of writing novels, post /export hide-sensitive. Use find&replace in your favourite text editor to systematically replace each occurrence of any public IP address potentially identifying you by a distinctive pattern such as my.public.ip.1.
