Description
W32/Rbot-ZQ is an IRC backdoor and network worm.
W32/Rbot-ZQ may spread to remote network shares protected by weak
passwords and computers vulnerable to common exploits. The worm also
opens up a backdoor, allowing unauthorised remote access to infected
computers via the IRC network, while running in the background as a
service process. The worm exploits the following vulnerabilities:
RPC-DCOM (MS04-12), LSASS (MS04-11) and WKS (MS03-049). For patches for
these vulnerabilities, see:
http://www.microsoft.com/technet/security/bulletin/MS03-049.mspx
http://www.microsoft.com/technet/security/bulletin/MS04-011.mspx
http://www.microsoft.com/technet/security/bulletin/MS04-012.mspx
W32/Rbot-ZQ can receive commands from a remote intruder to delete
network shares, log keypresses, participate in DDoS attacks, scan other
computers for vulnerabilities, steal passwords, steal registration keys
for computer games, create administrator accounts, terminate firewall
and anti-virus processes and capture video from webcameras attached to
the computer.
The worm creates numerous registry entries in order to alter system
security.

Description
W32/Sdbot-WS is a member of the W32/Sdbot family of network worms. The
worm can spread to weakly protected network shares, and to computers
already infected with W32/MyDoom.
The worm has a backdoor component that connects to a preconfigured IRC
mchannel, allowing an attacker to issue instructions to the worm, thus
giving access to an infected computer.
W32/Sdbot-WS can be instructed to harvest product keys; scan for remote
computers to infect; upload, download and execute files; as well as
retrieve information about an infected system.
Advanced
W32/Sdbot-WS is a member of the W32/Sdbot family of network worms. The
worm can spread to weakly protected network shares, and to computers
already infected with W32/MyDoom.
In order to run automatically when Windows starts up the worm copies
itself to the <System> folder as winupdate.exe and creates the following
registry entries:
HKLM\Software\Microsoft\Windows\CurrentVersion\Run\
Windows Update
winupdate.exe
HKLM\Software\Microsoft\Windows\CurrentVersion\RunServices
Windows Update
winupdate.exe
HKCU\Software\Microsoft\Windows\CurrentVersion\Run\
Windows Update
winupdate.exe
Once installed, W32/Sdbot-WS connects to a preconfigured IRC server and
joins a channel from which an attacker can issue further commands. These
commands can cause the infected computer to perform any of the following
actions:
Scan for remote computers to infect
Steal product keys
Upload, download and execute files
Retrieve information about an infected system
The worm can be instructed to secure an infected computer, and does this
by attempting to delete the C$, D$, IPC$ and ADMIN$ network shares, and
disable DCOM by setting the following registry entry:
HKLM\Software\Microsoft\OLE
EnableDCOM

W32/Rbot-ZN is a worm with backdoor Trojan functionality.
W32/Rbot-ZN is capable of spreading to computers on the local network
protected by weak passwords after receiving the appropriate backdoor
command.
W32/Rbot-ZN will attempt to spread by exploiting the following
vulnerabilities:
DCOM (MS04-012)
LSASS and IIS5SSL (MS04-011)
Microsoft SQL servers with weak passwords
When first run, W32/Rbot-ZN moves itself to the Windows system folder as
INIT3.EXE. In order to run automatically each time a user logs in,
W32/Rbot-ZN will set the following registry entries:
HKCU\Software\Microsoft\Windows\CurrentVersion\Run
Unix File Support
init3.exe
HKCU\Software\Microsoft\Windows\CurrentVersion\RunServices

The worm runs continuously in the background, providing backdoor access
to the infected computer over IRC channels.

The worm spreads to network shares with weak passwords and also by using
the RPC-DCOM security exploit (MS03-039).
When run W32/Rbot-AAC moves itself to the Windows System folder as a
hidden, read-only, system file named msnmsgs.exe. The worm then copies
itself to the following filenames:
C:\eminem vs 2pac.scr
C:\funny pic.scr
C:\photo album.scr
The above 3 files have their read-only, hidden, system and archive file
attributes set.
W32/Rbot-AAC then creates the following registry entries so as to run
itself on computer logon:

actions when instructed to do so by a remote attacker:
scan ports
create an HTTPD server
create a SOCKS4 server
participate in distributed denial of service (DDoS) attacks
download and run files from the Internet
log keystrokes to the file %SYSTEM%\keys.txt
capture clipboard information
terminates anti-virus, security and Windows applications and processes

W32/Agobot-RJ is a network worm with backdoor functionality for the
Windows platform.
W32/Agobot-RJ is capable of spreading to computers on the local network
protected by weak passwords.
When first run, W32/Agobot-RJ copies itself to the Windows system folder
as updateXPSPC.exe and creates the following registry entries to run
itself each time a user logs on:
HKLM\Software\Microsoft\Windows\CurrentVersion\Run
USB 2.0 Driver
updateXPSPC.exe
HKLM\Software\Microsoft\Windows\CurrentVersion\RunServices
USB 2.0 Driver
updateXPSPC.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-RJ attempts to terminate and disable various anti-virus and
security related programs and modifies the HOSTS file located at
<Windows system folder>\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 file:
127.0.0.1 avp.com
127.0.0.1 ca.com
127.0.0.1 customer.symantec.com
