A couple of days ago i have some issues with a router rb3011, i have found some firewall rules created and some messages aparently due to a system access from some type off botnet because the mikronit was not with the firmaware up to date, i have changed all my passwords and due to one suggestion in Mikrotik forum, I have tryed to upgrade the firmware several ways with no success, I am not a mikrotik expert so i need your advice to see if there is a way to uograde the mikrotik device, there was a second rb3011 infected and i am having the same experience, the ones that are not infected are upgrading ok.
Thank you in advance.
