Did they mean to do “sun-ack” on port 23 and not 22 which would make more sense since 22 is secure shell and port 23 is Telnet and NOT secure meaning a breach is more likely…?

I don't know what to look for here. port 23 failed, port 22 syn-ack and port 3389 just syn. Don't know how to come to the conclusion any of these was the breach... I'm just assumming its RDP cause it tried twice??

It's C. You could see that Port 23 was RST which means it was terminated and port 22 is Syn-ack which means it was established
