RB951N bug mikrotik DO DDOS attack

Thu Mar 26, 2020 9:38 pm

In general - the subscriber called - started picking. Replaced the abnormal activity of the pruter at port 23 .. Okay. I screwed all the service ports of the microbe on the firewalls on the brasses.
Day went to the subscriber. Reset the router. Otherwise, he was dumped somehow sooo tight.
He scored the settings and locked all the services .. In the evening, a panic at the abon. Remote access show strange!

Situation - Mikrotik remembered the IP address given 2 connections back !!!!! and began to arrange a robust DDOS from an already released address, natting his current session !!!!!!
Someone came across this ..
Microtik says that the firmware is "up to date"

Any Ideas???

I can hardly read your Runglish... Try using proper Russian without any traces of slang before feeding it to Google translate (or whatever else you are using).

Anyways. You wrote the firmware is current, however your screenshot says you are running RouterOS version 6.30.4. That is very far from being current. The current versions are 6.45.8 (Long-term) and 6.46.4 (Stable). Try upgrading your device first. And since a lot of vulnerabilities were fixed since 6.30.4 Netinstall is strongly recommended. And don't forget to do /export (not backup!) before the upgrade.

And as I can see from your pic seems that you (device connected to mikrotik) is attacking others with syn flood. Maybe one of devices has malware or is a botnet.
