More Information
W32/Rbot-ARM is a worm and IRC backdoor Trojan for the Windows platform.
W32/Rbot-ARM spreads to other network computers by exploiting common buffer overflow vulnerabilities, including: LSASS (MS04-011), RPC-DCOM (MS04-012), WKS (MS03-049) (CAN-2003-0812), Veritas (CAN-2004-1172), MSSQL (MS02-039) (CAN-2002-0649) and ASN.1 (MS04-007) and by copying itself to network shares protected by weak passwords.
W32/Rbot-ARM 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-ARM copies itself to <System>\explorer.com.
The following registry entries are created to run explorer.com on startup:
HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Run
Explorer soft
explorer.com
HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\RunServices
Explorer soft
explorer.com
The following registry entry is set:
HKCU\Software\Microsoft\OLE
Explorer soft
explorer.com
The following patches for the operating system vulnerabilities exploited by W32/Rbot-ARM can be obtained from the Microsoft website:
