Bagle.N

Name : Bagle.N
Category:Virus
Type:Virus
Platform:Win32

Summary



A new Bagle variant - Bagle.N was found in the wild late one evening
on March 13th, 2004. Some antivirus programs might detect this
new variant as "Beagle.M".

Additional Details

Bagle.N sends highly variable emails, containing a PIF or EXE attachment.

The icon for the EXE attachments resembles the icon for TrueType fonts:



Sometimes this attachment is compresses inside a ZIP or RAR archive.

Sometimes this archive is encrypted with a password. If so, the password is not listed in the email in plaintext (as in some previous Bagle variants),
but instead shown as a BMP, JPG or GIF graphic image, such as:

Password:

The virus body contains a picture of a butterfly made with ASCII graphics...which is never shown:



Bagle.N executable is packed with an unmodified version of UPX. Once the unpacking is performed, it follows a small de-scrambling routine, which goes through the worm's code section. After this step the main code starts running.

This variant of the Beagle worm will terminate processes from the following list, which includes all kinds of security software:
