More Information
W32/Rbot-LF is a worm with backdoor Trojan functionality.
W32/Rbot-LF is capable of spreading to computers on the local network protected by weak passwords after receiving the appropriate backdoor command.
W32/Rbot-LF may also spread by exploiting the following vulnerabilities:
LSASS (MS04-011)
DCOM (MS04-012)
Microsoft SQL servers with weak passwords.
W32/Rbot-LF may attempt to spread with a filename of BLING.EXE.
When first run, W32/Rbot-LF copies itself to the Windows system folder as CNSTAT.EXE and runs this copy of the worm. The copy will then attempt to delete the original file. In order to run each time Windows is started, W32/Rbot-LF will set the following registry entries:
HKLM\Software\Microsoft\Windows\CurrentVersion\Run\
System Failure Statistic = cnstat.exe
HKLM\Software\Microsoft\Windows\CurrentVersion\RunServices\
System Failure Statistic = cnstat.exe
HKCU\Software\Microsoft\Windows\CurrentVersion\Run\
System Failure Statistic = cnstat.exe
The worm runs continuously in the background providing backdoor access to the infected computer.
The backdoor component of W32/Rbot-LF can be used to:
Initiate distributed denial-of-service (DDOS) attacks using ICMP, SYN, UDP,
PING, ACK and TCP flooding.
Redirect TCP and SOCKS4 traffic.
Provide a remote login shell.
Download, upload, delete and execute files.
Set up an HTTP, TFTP and FTP file server.
Steal passwords (including PayPal account information).
Log key presses.
Capture screenshots.
Capture webcam pictures and videos.
List and kill processes.
Stop, start, and pause services.
Open and close vulnerabilities.
Port scan for vulnerabilities on other remote computers.
Send emails as specified by the remote user.
Flush the DNS and ARP caches.
Shut down and reboot the computer.
Add and delete network shares and users.
Sniff network traffic for passwords.
