Description
W32/Mytob-BY is a mass-mailing worm and IRC backdoor Trojan.
W32/Mytob-BY can spread by sending itself as an email attachment to
email addresses it harvests from the infected computer, either as an
attachment with a double-extension or as a zip file containing a file
with a double-extension. W32/Mytob-BY avoids sending emails to addresses
containing certain strings in them.
W32/Mytob-BY processes the emails it has harvested by splitting them
into name and domain. Once it has sent itself to the emails it has
harvested, it uses a predefined list of names with the harvested
domains. W32/Mytob-BY spoofs the sender, sending emails as if from one
of the following at the same domain as the recipient:
support
administrator
mail
service
admin
info
register
webmaster
For example if sending itself to name@example.com, W32/Mytob-BY might
send the email as if from admin@example.com.
Emails sent by the worm have characteristics from the following:

W32/Mytob-BY is a mass-mailing worm and IRC backdoor Trojan.
W32/Mytob-BY runs continuously in the background, providing a backdoor
server which allows a remote intruder to gain access and control over
the computer via IRC channels, including the ability to download and
execute files on the infected computer.
W32/Mytob-BY can spread by sending itself as an email attachment to
email addresses it harvests from the infected computer, either as an
attachment with a double-extension or as a zip file containing a file
with a double-extension. W32/Mytob-BY avoids sending emails to addresses
containing certain strings in them.

protected by weak passwords.
Advanced
W32/Rbot-AGP is a worm with backdoor functionality for the Windows
platform that spreads to other network computers by exploiting a number
of known vulnerabilities and by copying itself to network shares
protected by weak passwords.
W32/Rbot-AGP runs continuously in the background, providing a backdoor
server which allows a remote intruder to gain access and control over
the computer via IRC channels.
W32/Rbot-AGP includes functionality to access the internet and
communicate with a remote server via HTTP.
Once executed W32/Rbot-AGP moves itself to the file <Windows system
folder>\scrnsaver.scr, and in order to be able to run automatically when
Windows starts up sets the following registry entries:
HKLM\Software\Microsoft\Windows\CurrentVersion\Run
Screen Saver
scrnsaver.scr
HKLM\Software\Microsoft\Windows\CurrentVersion\RunServices
Screen Saver
scrnsaver.scr
When W32/Rbot-AGP is installed it creates the file <Windows system
folder>\svkp.sys which is a legitimate driver for NT based systems.
The file SVKP.sys is registered as a new system driver service named
"SVKP", with a display name of "SVKP" and a startup type of automatic,
so that it is started automatically during system startup. Registry
entries are created under:
HKLM\SYSTEM\CurrentControlSet\Services\SVKP\

Troj/Bancb-Fam detects members of the Bancban family of Trojans. Members
of this family typically attempt to steal confidential information when
a user visits banking-related websites.
Trojans of this family typically monitor URLs entered into Internet
Explorer. When certain websites are visited, the Trojan may display a
fake user interface in order to trick the user into entering
confidential details. Stolen information is sent by email to a remote
user.
Typically a registry entry is created in order to run the Trojan on
system startup:

* Forges the sender's email address
Aliases
* Net-Worm.Win32.Mytob.gen
Prevalence (1-5) 2
Description
W32/Mytob-CT is a mass-mailing worm and IRC backdoor Trojan.
W32/Mytob-CT can spread by sending itself as an email attachment to
email addresses it harvests from the infected computer, either as an
attachment with a double-extension or as a zip file containing a file
with a double-extension. W32/Mytob-CT avoids sending emails to addresses
containing certain strings in them.
W32/Mytob-CT processes the emails it has harvested by splitting them
into name and domain. Once it has sent itself to the emails it has
harvested, it uses a predefined list of names with the harvested
domains. W32/Mytob-CT spoofs the sender, sending emails as if from one
of the following at the same domain as the recipient:
support
administrator
mail
service
admin
info
register
webmaster
For example if sending itself to name@example.com, W32/Mytob-CT might
send the email as if from admin@example.com.
Emails sent by the worm have characteristics from the following:
