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.

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

Prevalence (1-5) 2
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.

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).
In order to run automatically when Windows starts up the worm copies
itself to the Windows system folder as mssupdate.exe and creates the
following registry entries:
HKLM\Software\Microsoft\Windows\CurrentVersion\Run
Start Uppings
mssupdate.exe
HKLM\Software\Microsoft\Windows\CurrentVersion\RunServices
Start Uppings
mssupdate.exe
HKCU\Software\Microsoft\Windows\CurrentVersion\Run
Start Uppings
mssupdate.exe
HKCU\Software\Microsoft\Windows\CurrentVersion\RunServices
Start Uppings
mssupdate.exe
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
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
Flush the DNS cache
Log any keystrokes made on the computer
Disable security software
To secure an infected computer network shares are deleted, and DCOM is
disabled 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 unsecure an infected computer C$, ADMIN$ and IPC$ network shares are
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:
