I have a little .wav from the game "Kingpin" play whenever portsentry blocks somebody doing a little scan on my system ("You got close, but didn't make it!" it sez)
Well, i was woken up about 20 times last night as my computer kept screaming this out throughout the wee hours of the morning.

Check this out

It all seems to be eminating from the same network of sorts, and it all is looking for port 12345. I think this is the default port for netbus, what the heck is goin on?
Has anybody else witnessed a sudden increase of port scans?

Actually it's been really freaking quite here on cable. Which is really unusual. The only entries I find are from my ISP. Other than that, it's been really quiet. It's kinda eerie in a way. Because 2 months ago I was getting hits 3-4 times a day. Of course about 2 months ago I stopped using ICQ to so that may have something to do with it. I would ask my nieghbor but his NT box still can't get online.....

I AM on cable... that is what is weird. I have been on cable for about 2 years now, and this little rash of attacks has been the first I have seen (other than the authorized-scan.security.home.net checking for innd at port 119)

for a brief moment i thought it may have been due to my recent installation of napster and icq on the windows side of this boot.

However, i just booted back into win98 and ran Purge-it (http://www.purge-it.com) after starting napster and icq. And luckily none of these ports that are being scanned show up as listening. So it is just a rash of people out there scanning the world for trojans.
farging bastages.

Yes, isn't that interesting, and they are all in asia, Korea, mostly. I have been sending logsnips back to abuse@ whatever. Lots of it, too. http://www.linuxnewbie.org/ubb/smile.gif Look at FTP attempts, too, people with no passwords, at all, in here. SEND MAIL to the ISP, with times and proper logsnips, else, we seem to be condoning it all, ya know?

Also, look at this one, where he hits my pop3 server:

Aug 13 12:41:28 gordo ipop3d[18615]: pop3 service init from 211.46.122.121
Aug 13 12:41:57 gordo ipop3d[18615]: No such file or directory while reading line user=??? host=[211.46.122.121]

This IP is in Korea, but they provide no English language information on the ISP, so I can't email them.
AND it continues, right on through today.

Same here... Its kind of disturbing... where have all the skript kiddies gone? (More importantly, did they get in through some exploit I haven't heard of yet, and are systmatically wiping my logs? Hmmm... Nah)

I'm on cable too and I've been getting the same sort of hits on my firewall that scoobydope and rayjones have been getting. One even tried a pop3 login as root!

My ISP portscans me a LOT...

I've never really gotten any attempts at portscanning me except the occainsonal one or two isolated blocked packets. Nothing much for me. 56k btw.

pop3 and ftp are backups for testing easily guessable passwords, in case telnet is closed.

Of course, I've never even seen "Citizen Kane" and "ROSEBUD" is a pretty stupid root password, but I'm surprised more people didn't give it a try out of sheer curiosity!

Have you guys ever tried blocking the @home security scans? I get at least 5 a day, and they check the whole range of ports.....
Just wondering if they'd get pissed.
