    * Worm

How it spreads  
    * Network shares

Affected operating systems  
    * Windows

Side effects  
    * Allows others to access the computer
    * Steals information
    * Reduces system security
    * Records keystrokes
    * Installs itself in the Registry
    * Exploits system or software vulnerabilities

Prevalence (1-5) 2

Description
W32/Rbot-UD is a member of the W32/Rbot family of network worms. The 
worm can spread to weakly protected network shares, and to computers 
vulnerable to the RPC-DCOM, LSASS and WebDav exploits. See Microsoft 
Sercurity Bulletins MS04-012, MS04-011 and MS03-007 respectively.

The worm has a backdoor component that connects to a preconfigured IRC 
channel, allowing an attacker to issue instructions to the worm, thus 
giving access to an infected computer.

W32/Rbot-UD can be instructed to log any keystrokes made on an infected 
computer, search for and retrieve product keys, upload, download and 
search for files, and participate in distributed denial-of-service 
(DDoS) attacks.

W32/Rbot-UD is a member of the W32/Rbot family of network worms. The 
worm can spread to weakly protected network shares, and to computers 
vulnerable to the RPC-DCOM, LSASS and WebDav exploits. See Microsoft 
Sercurity Bulletins MS04-012, MS04-011 and MS03-007 respectively.

In order to run automatically when Windows starts up the worm copies 
itself to the Windows system folder as icp.exe and creates the following 
registry entries:

HKLM\Software\Microsoft\Windows\CurrentVersion\Run
Internet Content Publisher
icp.exe

HKLM\Software\Microsoft\Windows\CurrentVersion\RunServices
Internet Content Publisher
icp.exe

HKCU\Software\Microsoft\Windows\CurrentVersion\Run
Internet Content Publisher
icp.exe

Once installed, W32/Rbot-UD connects to a preconfigured IRC server and 
joins a channel from which an attacker can issue further commands. These 
commands can cause the infected machine to perform any of the following 
actions:

Initiate distributed denial-of-service (DDoS) attacks
Flood a remote host (by either SYN, TCP, UDP, ICMP or ping)
Steal product keys
Start a SOCKS4 or HTTP server
Scan remote computers for vulnerabilities
Execute arbitrary commands
Upload, download and search for files
Send emails as specified by the remote user
Create and delete network shares
Browse and terminate processes running on the computer
Log any keystrokes made on the computer

The worm can be commanded to secure an infected computer from further 
infection, or open it up for further infection. Securing an infected 
computer involves deleting any network shares and disabling DCOM by 
setting the following registry entry:

HKLM\Software\Microsoft\OLE
EnableDCOM
N

Additionally, anonymous access to the IPC$ is restricted by setting the 
following registry entry:

HKLM\SYSTEM\CurrentControlSet\Control\Lsa
restrictanonymous
1

To allow further infection on an infected computer a C$ network share is 
added, and DCOM is enabled by setting the following registry entry:

HKLM\Software\Microsoft\OLE
EnableDCOM
Y

Anonymous access to the IPC$ is allowed by setting the following 
registry entry:

HKLM\SYSTEM\CurrentControlSet\Control\Lsa
restrictanonymous
0

Description
W32/Rbot-TS is a member of the W32/Rbot family of network worms. The 
worm can spread to weakly protected network shares, and to computers 
vulnerable to the RPC-DCOM and LSASS exploits (see Microsoft Security 
Bulletins MS04-012 and MS04-011 respectively).

The worm has a backdoor component the connects to a preconfigured IRC 
channel, allowing an attacker to issue instructions to the worm, thus 
giving access to an infected computer.

W32/Rbot-TS can be instructed to disable security software, scan remote 
computers, create and delete network shares, log any keystrokes made on 
the computer, upload and download files, and run programs.

Once installed, W32/Rbot-TS 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:

Initiate distributed denial-of-service (DDOS) attacks
Flood a remote host (by either SYN, TCP, UDP or ping)
Start a SOCKS4 proxy server
Port scan remote computers
Execute arbitrary commands
