Just curious if any of you guys are sys admins and seeing what I'm
seeing. In recent months I've got probe/scan/spam from new sources like Egypt, Lybia, Sudan, Arab Emirates and Suadi Arabia. Thats in addition to the usual China, Sth Korea, Taiwan, Russia, Poland, Romania, Latvia, Czech Republic, Morocco, Nigeria and Sth Africa. There is alot of file sharing scanning for music/films etc, individuals I think, not robots, but not fee-paying clients either! I don't know about the rest of you but during the last 6 or 7 yrs, my traffic has shot up considerably, shame its not all page hits spam [webmail outside the system] runs at an average 1:100, i.e. for every 1 genuine email, there are about 100 spam, sometimes as high as 200. Then you've got the harvesters, port scanners, proxy or relay seekers, open resolver seekers, hackers, the list goes on. Nowadays, I think a software firewall alone can't cut it judging by the level of bad traffic that the hardware unit is filtering out. So, has it started already? Phil |

It currently harvests an average of about 130 spam e-mails a day alone. The web and mail servers get hit so hard, you'd think I was an ISP the size of AOL. Dictionary attact being tried right now on the webserver. Hmmmm IP out of Taiwan. Fsckers. > > So, has it started already? Dunno, but I wish there was a slick way to hit 'em back.

I did this a few years back at a company and it worked well. You just need to be sure you won't get email (that matters) from these countries. I blocked most of the world and it helped a lot w/ spam and other BS. Jonathan |

I use SPEWS, Spamcop, and a couple of other blocklists. We are talking about attacks directly on the servers. Gotta leave acouple of ports open or just enjoy your intranet. I use DenyHosts, which is pretty good at blocking failed login attempts. I'd just like to burn their fingers at the same time -- JaR MCNGP 22 Dept of reasonable force Remove hat to reply |

The idea being to alter spammer's economic model to beyond it being viable, see; http://www.okopipi.org http://www.scambaiter.com http://groups.google.com/group/SPDSSupport?lnk=li&hl=en Note: I can't vouch for who these people are or their motives, also I'm concerned about possible abuse of the software but from a security point of view, you need to know what is out there just in case. |

Preferably with enough vigor that it at causes injury to the luser at the keyboard. I know, they are more of a nuisance than a threat, but it still just p1sses me off. > Note: I can't vouch for who these people are or their motives, also I'm > concerned about possible abuse of the software but from a security point > of view, you need to know what is out there just in case.
