Heads up ppl, there's a new bugbear around. It is NOT detected by the current McAfee DAT files (probably other vendors too). I've found it by using http://www.webimmune.net. The new DAT should be able to detect it but unfortunately it's not yet available for download :(
More info can be found here:

Bugbear.A was the most Widespread Virus in 2002
Helsinki, Finland, June 5, 2003- F-Secure is warning the computer users of a worm known as Bugbear.B. This worm was first seen on Thusday morning, June 5th, 2003. It is a new variant of the Bugbear.A e-mail worm (also known as
Tanatos) that was found on Monday, September 30, 2002. Bugbear.A was the most common and widespread virus in 2002.
The most alerting capacity of this worm is that it includes a large list of domains belonging mostly to banks. The worm checks if an infected computer is in one of these domains, and makes changes to the system in these computers.
"The list of bank domains that the worm has, includes banks from all over the world; Europe, US, Asia and Africa", says Mikael Albrecht, Product Manager of F-Secure. "Bugbear.B changes system settings if activated in one of these banks. The purpose of these actions is still unknown. They may be part of a malicious scenario but we can't confirm that yet", he continues.
Bugbear.B is a very complex polymorphic virus that spreads through both email and network shares. The worm sends e-mails with various contents. It uses a known vulnerability to execute the attachment automatically when the e-mail is opened.
"This virus is tricky, it contains many different techniques. It has UPX compression, encryption with random keys, backdoors, key-logging, retro-functionality, aggressive mass-mailing and network worm capabilities.", explains Mikael Albrecht. "The network worm capabilities may be dangerous to large organisations. It may cause very fast outbreaks if this virus manages to get inside the firewall".
More information on the Bugbear.B virus is available online at http://www.f-secure.com/v-descs/bugbear_b.shtml .The page includes technical descriptions and images.
I always trust my AV to BidDefender ( especially for Win32 @mm ).
I found the BugBear file at http://www.bitdefender.com/bd/site/v..._id=1&v_id=133
u may also download the anti bugbear at that site , but as ussualy , it couldnt clean or delete the files automatically, so u might be active the programm and run it.Quote:

They are good and their products are not so heavy on my system....but still they are not so fast in their response to virus breakdowm and worms outbreaks....but I think this is a matter of time to bypassed.
Anyway the link which they tend to advertize to download the tool for Bugbear was not working when I tried this morning......in order to place a link into my forum.....:)
yep support , i doesnt responds ani viruses untill u found the viruses from other AV ( McAfee , Norton , etc ), but it works well. If u failed donwload the Anti-V for BigBear, u may download here.

I got this in my mail today from slashdot.
And it is using the same old exploits!
Stoped on our work systems today.. AV?.. Patches? Warnings?.. None of these just a sharp eye and a good e-Mail Policy.. Bloody CA.. (aka VET in Aussi) missed them completly..
I just hope SirDice didn't have too many headaches from it today.. seems there was a hammering earlier..
Cheers
happy reading

No trouble here :D I'm just glad we have a good content-scanner on our email. It blocks all executables by taking the file apart. So changing mime types, changing the extension or even zipping it doesn't matter. It still is recognised as an executable.Quote:

I was just a bit worried because it didn't get noticed as a virus (but it had all the markings of a virus). I did some updating this morning and it's now properly recognised.
They're still pouring in like mad though. Wouldn't be supprised if it would top the charts after the weekend.
Well, Support's post hinted at this but I just saw this posted on Yahoo! News:
http://story.news.yahoo.com/news?tmp.../virus_banks_2
Seems that Bugbear.b may have been aimed largely at big financial institutions.. I wonder if there is a terrorism link somehow in all this? I guess it's possible, but I'm not too sure about the chances of it..
