Look Like another new one

Morning All,


Just got this warning this morning. This little nasty, after you execute
it (meaning clicking on to open it. something we WON'T be doing,
right?!?) attempts to disable your antivirus programs (which we all have
a copy in our PC and keeping it up-to-date, right?!?). Oh well, on to
the Bug de jour:


Name: W32/Yaha-E
Type: Win32 worm
Date: 20 June 2002


Description:


W32/Yaha-E is a worm which spreads via email. The worm has its own
SMTP client software and uses either an SMTP server found by examining
the Windows registry or one from a list contained within the worm
itself.


The email sent by the worm is highly variable. The subject line of the
email is created using a combination of words and phrases from the
following list:


searching for true Love
you care ur friend
Who is ur Best Friend
make ur friend happy
True Love

Free Screen saver

The message text begins:


"Hi
Check the Attachment ..
See u "


or


"Attached one Gift for u.. "


or


"wOW CHECK THIS "


The remainder of the message will resemble a forwarded email. The From
and Subject fields of the forwarded message are also variable but the
message will always contain the text:


"This e-mail is never sent unsolicited. If you need to unsubscribe,
follow the instructions at the bottom of the message.
***********************************************************

The attachment filename is made up of three parts- a name and two
extensions.


The name is chosen from:

The first extension is chosen from:


doc
mp3
xls
wav
txt
jpg
gif
dat
bmp
htm
mpg
mdb
zip


The second extension is chosen from:


pif
bat
scr


The worm also creates a copy of itself in the Recycle folder with a
name comprised of four random lower case characters. The path to this
copy is then added to the following registry entry to ensure that the
worm is run each time a program with an EXE extension is run:


HKLM\exefile\shell\open\command\default


Two files are created in the Windows folder. One has a DLL extension
and an eight character name created from the same four characters used
for the copy of the worm. This file contains a list of email addresses
found on the infected computer. The second file has the same name as
the copy of the worm and a TXT extension. This is a simple text file
containing the text "iNDian sNakes pResents yAha.E ".


The worm will attempt to disable security software by terminating any
of the following processes:


SCAM32
SIRC32
ZONEALARM
LOCKDOWN2000
AVP.EXE
CFINET32
CFINET
SAFEWEB
WEBSCANX
ANTIVIR

NAVW32

When the worm is first run it will imitate a screen saver by
repeatedly displaying the following messages on the screen in various
colours:


U r so cute today "! "!
True Love never ends
I like U very much!!!
U r My Best Friend


A copy of the attachment in base64 encoded format is created in the
folder C:\Windows\Temp with the filename kitkat.

 

Great post BillyBob!
Just for added info from Symantec .

Thanks should really go to Road Runner WebMaster.

Ink was not even dry on E-mail and three machines were receiving AV updates.
