More Information
W32/Sdbot-CCR is a worm and IRC backdoor Trojan for the Windows platform.
W32/Sdbot-CCR spreads to other network computers by exploiting common buffer
overflow vulnerabilities, including: RPC-DCOM (MS04-012), PNP (MS05-039) and
ASN.1 (MS04-007) and by copying itself to network shares protected by weak
passwords.
W32/Sdbot-CCR 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.

When first run W32/Sdbot-CCR copies itself to <Windows>\Mscfg.exe.
The following registry entries are created to run Mscfg.exe on startup:
HKCU\Software\Microsoft\Windows\CurrentVersion\Run
Ms System Config
Mscfg.exe
HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Run
Ms System Config
Mscfg.exe
HKCU\Software\Microsoft\Windows\CurrentVersion\RunServices
Ms System Config
Mscfg.exe
HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\RunServices
Ms System Config
Mscfg.exe
W32/Sdbot-CCR sets the following registry entries, disabling the automatic
startup of other software:
HKLM\SYSTEM\CurrentControlSet\Services\wuauserv
Start
4
HKLM\SYSTEM\CurrentControlSet\Services\SharedAccess
Start
4
Note: disabling autostart for the SharedAccess service deactivates the
Microsoft Internet Connection Firewall (ICF).
Registry entries are set as follows:
HKCU\SYSTEM\CurrentControlSet\Control\Lsa
Ms System Config
Mscfg.exe
HKLM\SYSTEM\CurrentControlSet\Control\Lsa
