W32/Rbot-QN is an IRC backdoor Trojan and network worm.
W32/Rbot-QN may spread to remote network shares protected by weak passwords and computers vulnerable to common exploits. The worm also opens up a backdoor, allowing unauthorised remote access to infected computers via the IRC network, while running in the background as a service process.
W32/Rbot-QN copies itself to the Windows system folder and creates the following registry entries to run itself automatically on log-on:
HKLM\Software\Microsoft\Windows\CurrentVersion\Run
Windows debug logging
winloggs.exe
HKLM\Software\Microsoft\Windows\CurrentVersion\RunServices
Windows debug logging
winloggs.exe
HKCU\Software\Microsoft\Windows\CurrentVersion\Run
Windows debug logging
winloggs.exe
W32/Rbot-QN also attempts to alter the following registry entries, if they are not already set:
HKLM\SOFTWARE\Microsoft\Ole
EnableDCOM
N
HKLM\SYSTEM\ControlSet001\Control\Lsa
restrictanonymous
1
HKLM\SYSTEM\CurrentControlSet\Control\Lsa
restrictanonymous
1
W32/Rbot-QN can receive commands from a remote intruder to delete network shares, log keypresses, participate in DDoS attacks, scan other computers for vulnerabilities, steal passwords, steal registration keys for computer games and capture video from web cameras attached to infected computers.
