More Information

W32/Rbot-AOP is a network worm and IRC backdoor Trojan for the Windows
platform.

W32/Rbot-AOP spreads to other network computers by exploiting common buffer
overflow vulnerabilites, including RPC-DCOM (MS04-012).

W32/Rbot-AOP 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-AOP copies itself to <System>\tyack.pif.

The following registry entries are created to run tyack.pif on startup:

HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Run
tiyack drive
tyack.pif

HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\RunServices
tiyack drive
tyack.pif

The following registry entry is set:

HKCU\Software\Microsoft\OLE
tiyack drive
tyack.pif
