W32/Netsky-C is a worm which spreads via shared networks and by emailing
itself to addresses found within files located on drives C: to Z:.
The email subject line, message text and attachment filename are
randomly chosen from lists within the worm.
The name of the attached file is chosen from:
associal, msg, yours, doc, wife, talk, message, response,
creditcard, description, details, attachment, pic, me, trash,

The attachment extension will be ZIP, COM, EXE, PIF or SCR and may be
preceded by .DOC, .HTM, .RTF or .TEXT. (e.g. visa.htm.scr)
When first run W32/Netsky-C copies itself to the Windows folder as
winlogon.exe and creates the following registry entry so that
winlogon.exe is run automatically each time Windows is started:
HKLM\Software\Microsoft\Windows\CurrentVersion\Run\ICQNet
= <WINDOWS>\winlogon.exe -stealth
W32/Netsky-C spreads via file sharing networks by copying itself to
folders on drives C: to Z: whose name contains the sub-string 'Shar',
using a filename randomly chosen from the following list:

W32/Agobot-AAZ is a network worm with backdoor Trojan functionality for
the Windows platform.
W32/Agobot-AAZ is capable of spreading to computers on the local network
protected by weak passwords.
When first run, W32/Agobot-AAZ copies itself to the Windows system
folder as walg32.exe and creates the following registry entries to run
itself each time a user logs on:
HKLM\Software\Microsoft\Windows\CurrentVersion\Run
Windows Application Layer Gateway
"walg32.exe"
HKLM\Software\Microsoft\Windows\CurrentVersion\RunServices
Windows Application Layer Gateway
"walg32.exe"
The backdoor component runs continuously in the background providing
backdoor access to the computer through IRC channels. The backdoor
component can be instructed to perform the following functions:
harvest email addresses
steal product registration information for certain software
take part in Distributed Denial of Service (DDoS) attacks
scan networks for vulnerabilities
download/execute arbitrary files
start a proxy server (SOCKS4/SOCKS5)
start/stop system services
monitor network communications (packet sniffing)
add/remove network shares
send email
log keypresses
W32/Agobot-AAZ attempts to terminate and disable various anti-virus and
security related programs and modifies the HOSTS file located at
%SYSTEM%\Drivers\etc\HOSTS, mapping selected anti-virus websites to the
loopback address 127.0.0.1 in an attempt to prevent access to these
sites. Typically the following mappings will be appended to the HOSTS

Description
W32/Rbot-RF is a network worm and IRC backdoor Trojan for the Windows
platform.
W32/Rbot-RF spreads using a variety of techniques including exploiting
weak passwords on computers and SQL servers, exploiting operating system
vulnerabilities (including DCOM-RPC, LSASS, WebDAV and UPNP) and using
backdoors opened by other worms or Trojans.
W32/Rbot-RF can be controlled by a remote attacker over IRC channels.
The backdoor component of W32/Rbot-RF can be instructed by a remote user
to perform the following functions:
start an FTP server
start a Proxy server
start a web server
take part in distributed denial of service (DDoS) attacks
log keypresses
capture screen/webcam images
packet sniffing
port scanning
download/execute arbitrary files
start a remote shell (RLOGIN)

Description
W32/Kassbot-D is a network worm with backdoor functionality for the
Windows platform.
The backdoor component joins a predetermined IRC channel and awaits
further commands from remote attackers.
W32/Kassbot-D monitors internet sessions and begins logging keypresses
when it detects traffic to certain banking websites.
Advanced
W32/Kassbot-D is a network worm with backdoor functionality for the
Windows platform.
When run, W32/Kassbot-D copies itself to the Windows system folder as
spools.exe and sets the following registry entry in order to run each
time a user logs on:
HKLM\Software\Microsoft\Windows\CurrentVersion\Run
Spools Service Controller
<Windows system folder>\spools.exe
W32/Kassbot-D drops a helper file to the Windows system folder as
xee32.dll. Sophos's anti-virus products detect xee32.dll as
W32/Kassbot-C.
The backdoor component joins a predetermined IRC channel and awaits
further commands from remote attackers. The backdoor can be instructed
to perform various tasks, including:
-start a proxy server
-take part in distributed denial of service (DDoS) attacks
-download and execute arbitrary files
-download updated copies of itself
-monitor internet sessions for visits to certain banking websites
-log keypresses
-serve as an email relay, allowing remote users the ability to route
email through the infected computer
-list/terminate processes
-redirect HTTP requests to alternate sites
-list,modify or delete files/folders
-execute arbitrary commands
-search the infected computer for specified files
To achieve the functionality of redirecting of HTTP requests,
W32/Kassbot-D modifies the HOSTS file (typically located in <Windows
system folder>\Drivers\etc). The worm initially appends data to the
HOSTS file which prevents access to the following domains, though it can
be instructed to append additional data via backdoor commands:

* Network shares
Affected operating systems
* Windows
Side effects
* Allows others to access the computer
* Sends itself to email addresses found on the infected computer

Prevalence (1-5) 2
Description
W32/Mytob-BZ is a mass-mailing worm and backdoor Trojan that can be
controlled through the Internet Relay Chat (IRC) network.
W32/Mytob-BZ is capable of spreading through email and through various
operating system vulnerabilities such as LSASS (MS04-011).
W32/Mytob-BZ harvests email addresses from files on the infected
computer and from the Windows address book.
Advanced
W32/Mytob-BZ is a mass-mailing worm and backdoor Trojan that can be
controlled through the Internet Relay Chat (IRC) network.
When first run W32/Mytob-BZ copies itself to the Windows system folder
as taskgmr.exe and creates the following registry entries:
HKCU\System\CurrentControlSet\Control\Lsa
W1NTASK
taskgmr.exe
HKCU\Software\Microsoft\OLE
W1NTASK
taskgmr.exe
HKCU\Software\Microsoft\Windows\CurrentVersion\Run

W1NTASK
taskgmr.exe
HKLM\Software\Microsoft\Windows\CurrentVersion\RunServices
W1NTASK
taskgmr.exe
W32/Mytob-BZ copies itself to the root folder as:
funny_pic.scr
my_photo2005.scr
see_this!!.scr
and drops a file called hellmsn.exe (detected by Sophos as W32/Mytob-D)
in the same location. This component attempts to spread the worm by
sending the aforementioned SCR files through Windows Messenger to all
online contacts.
W32/Mytob-BZ also appends the following to the HOSTS file to deny access
to security related websites:
127.0.0.1 www.symantec.com

W32/Mytob-BZ is capable of spreading through email and through various
operating system vulnerabilities such as LSASS (MS04-011). Email sent by
W32/Mytob-BZ has the following properties:
Subject line:
document
Good day
Mail Delivery System
Mail Transaction Failed
message
readme
Server Report
Status
Message text:
'This is a multi-part message in MIME format.'
'Mail transaction failed. Partial message is available.'
'The message contains Unicode characters and has been sent as a binary
attachment.'
'The message cannot be represented in 7-bit ASCII encoding and has been
sent as a binary attachment.'
'The original message was included as an attachment.'
'Here are your banks documents.'
The attached file consists of a base name followed by the extentions
PIF, SCR, EXE or ZIP. The worm may optionally create double extensions
where the first extension is DOC, TXT or HTM and the final extension is
PIF, SCR, EXE or ZIP.
W32/Mytob-BZ harvests email addresses from files on the infected
computer and from the Windows address book. The worm avoids sending
email to addresses that contain the following:
