More Information
W32/Rbot-ALM is a worm and IRC backdoor Trojan for the Windows platform.
W32/Rbot-ALM spreads:
- to other network computers infected with: Troj/Kuang, Troj/Sub7, Troj/NetDevil, W32/MyDoom, W32/Bagle and Troj/Optix
- to other network computers by exploiting common buffer overflow vulnerabilites, including: LSASS (MS04-011), RPC-DCOM (MS04-012), WKS (MS03-049) (CAN-2003-0812), WebDav (MS03-007), IIS5SSL (MS04-011) (CAN-2003-0719), MSSQL (MS02-039) (CAN-2002-0649), UPNP (MS01-059), Veritas (CAN-2004-1172) and Dameware (CAN-2003-1030)
- by copying itself to network shares protected by weak passwords
The following patches for the operating system vulnerabilities exploited by W32/Rbot-ALM can be obtained from the Microsoft website:
MS04-011
MS04-012
MS03-039
MS03-007
MS02-039
MS01-059
W32/Rbot-ALM 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/Rbot-ALM copies itself to <System>\mscnfg.exe.
The following registry entries are created to run mscnfg.exe on startup:
HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Run
Microsoft Update 32
mscnfg.exe
HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\RunServices
Microsoft Update 32
mscnfg.exe
Registry entries are set as follows:
