Another Virus Heads Up... or 6 mth old Defs won't cut it..

Name: W32/Yaha.E (aka. Worm/Lentin.F)
Alias: Worm/Yaha.E
Type: Internet Worm
Discovered: June 17, 2002
Size: 29.948KB
ITW: Unknown

Description:

W32/Yaha.E is a modification of Worm/Lentin (Valentine.scr), an
Internet worm that spreads by retrieving e-mail addresses from
the Windows Address Book, as well as, from addresses found in
cached webpages. In addition, to these methods, W32/Yaha.E also
can spread through contacts it finds in the MSM Messanger and the
ICQ database list.

It scans all files with the extension HTM, HTML and HTA

This variant arrives as another friendship screen saver

The subject is randomly selected from a pre-determined list

The name of the Attachment begins with one of the following names:
loveletter

.bat
.scr

If executed, the worm copies itself in the \Recycled\ directory
under a random filename (ie. "kiek.exe". Additionally, a text
file (using the same random characters) is also created in the
/windows/ directory. This text file contains the following:

It also modifies the following registry key:

HKEY_CLASSES_ROOT\exefile\shell\open\command
<default> = "c:\recycler\kiek" %1 %*

**This modification allows it to run each time another executable
file is ran.

Running the worm will display a screensaver with a multicolor
screensaver message that shakes the screen after it is complete.
The display messages are:

- True Love never Ends
- U r My Best Friend
- U r so cute today #!#!

cheers for the heads up und3ertak3r

This probably sounds really dumb, I was just wondering how restricted the Benjamin Worm is, because on this site [http://antivirus.about.com/library/weekly/aa052002a.htm] it says

Quote:

According to F-Secure, the Benjamin worm spreads only to and from computers that have the KaZaa network clients software installed

which is fair enough. But the MP3 downloads I get are from grokster which also downloads from KaZaa users, without me having installed KaZaa, so does that mean I could get it? I mean it sounds like obviously yes, I would, but I don't like assuming stuff and because it doesn't say I wondered if you knew? Although from what I have read the virus only replicates the most popular downloads, none of which would constitute my collection...!

Uhm... how are these so new and unique that: "6 mth old Defs won't cut it!"?

probably not a well worded subject.. i must admitt.

From my experience .. If you haven't updated your "Defs" for six months or more, you probably haven't even run a full scan of you system. Let alone letting the AV use heuristics during its scanns/ or during "auto protect".. or even bother with any security measures..

What do you mean my computer has a virus?!!!

is the common reply from my clients
and this is the usual justification..

Quote:

my computer came with a virus programm

and the clincher

Quote:

when i bought it 3 years ago

so if you fall into that group.. six month old defs won't cut it...

Thanks for the info, Und3ertak3r. :)

I try not to realize the harsh fact that people out there think that just because they have NAV or some other anti-virus installed that it protects against everything forever. Automated updates for these people are a must, as they don't know, and haven't found out, that they need to update them weekly.
