W32/Rbot-ADC is a worm and IRC backdoor Trojan for the Windows platform.
W32/Rbot-ADC spreads to other network computers by exploiting common buffer overflow vulnerabilites, including: LSASS (MS04-011), WKS (MS03-049) (CAN-2003-0812), MSSQL (MS02-039) (CAN-2002-0649) and WINS (MS04-045) and by copying itself to network shares protected by weak passwords.
W32/Rbot-ADC 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-ADC copies itself to <System>\jrdtifkkxbbsa.exe and creates the following registry entries to run jrdtifkkxbbsa.exe on startup:
HKCU\Software\Microsoft\Windows\CurrentVersion\Run
Systes
jrdtifkkxbbsa.exe
