I have been Port Scanned

[suzkaw]

Hello all,
My firewall just went off about 50 times! It was all from the same IP and it checked every port from 33473 to 33523. Were they trying to find trojans on my computer? Also what if they found an open port would they have full control of my computer?

Thanks for the help,
Eric

Port scans are very common. I wouldn't worry about it too much, even a scan of that magnitude (which isn't that bad). I wouldn't be concerned unless it happens again.

Were they scanning for trojans? I highly doubt it. When scanning for trojans, one typically scans for a specific one. No doubt they were scanning for vulnerabilities (duh), but it doesn't appear they were looking for openings created by a trojan.

If this happens several times from the same IP you should think to take action -> e-mail the attacker's ISP.

it checked every port from 33473 to 33523

I don't know trojans that use these ports by default. However, here are some trojans close to that number range
port 33333 - Prosiak
port 33911 - Spirit 2001a
port 34324 - BigGluck, TN

It was probably some vulnerabilities check. If your firewall droped the attempts you are still secure.
