stats

Recommended Posts

I was downloading the ChainReaction Cart today...As it was downloading...My Sygate Firewall detacted that there is an Attack towards my Computer..

Somebody is scanning your computer.

Your computer's UDP ports:

2467, 2469, 2471, and 2525 have been scanned from 203.84.196.38..

Well i check at www.dnsstuff.com under the whois...And i discover that the Ip is from .Yahoo...This is the reports..

Any Idea what is this all about ??? Seems weird why does Yahoo wants to scan or attack my Computer ?

Port Scans are common, however maybe install a different firewall if it puts your mind at ease. Look Here.

Thanx for the Link..Yeah i think many people is having the same problem...I think its normall :o  :D

It's only normal because many hackers out their try to find an opening in a weak firewall otherwise it generally is not common practice. Also, the computer running the scanner was not Yahoo per say but a client using Yahoo as their ISP and independant of their web services.

The other reason to run a portscanner is an admin testing his own firewall security. Since I manage a firewall server at the university I test to see how well the firewall is locked down due to many attempts by others to find openings.

hi'

if you could see that someone was scanning your com, this means for me that your com is not stealth!

it was a port scan not an attempt! , surely closed but not stealth!

use ZA instead :o

and for tools, make a search on cyberkit, free :D

it's a standalone app, and give you a lot of tools including port scanner and else.
