More Information
W32/Agobot-ABY is a worm and IRC backdoor Trojan for the Windows platform.
W32/Agobot-ABY 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/Agobot-ABY spreads to other network computers by exploiting the buffer overflow vulnerabilities: LSASS (MS04-011), RPC-DCOM (MS04-012), WKS (MS03-049) (CAN-2003-0812) and ASN.1 (MS04-007) and by copying itself to network shares protected by weak passwords.
When first run W32/Agobot-ABY copies itself to <System>\mssecure.exe.
The following registry entries are created to run mssecure.exe on startup:
HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Run
secures23
mssecure.exe
HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\RunServices
secures23
mssecure.exe
Registry entries are set as follows:
HKLM\SOFTWARE\Microsoft\Ole
EnableDCOM
N
HKLM\SYSTEM\CurrentControlSet\Control\Lsa
