W32/Rbot-AEG is a worm and IRC backdoor Trojan for the Windows platform.
W32/Rbot-AEG spreads to other network computers by exploiting common buffer overflow vulnerabilites, including: LSASS (MS04-011), RPC-DCOM (MS04-012) and MSSQL (MS02-039) (CAN-2002-0649) and by copying itself to network shares protected by weak passwords.
W32/Rbot-AEG 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.
W32/Rbot-AEG includes functionality to: steal confidential information, capture keystrokes, carry out DDoS flooder attacks and silently download, install and run new software.
When first run W32/Rbot-AEG moves itself to <System>\ipcconn.exe.
The following registry entries are created to run ipcconn.exe on startup:
HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\RunServices
IPC Connection
ipcconn.exe
HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Run
IPC Connection
ipcconn.exe
Registry entries are created under:
HKCU\Software\Microsoft\OLE
IPC Connection
ipcconn.exe
