More Information
W32/Rbot-PR is a network worm and IRC backdoor Trojan for the Windows platform.
The worm copies itself to a file named regsvr.exe in the Windows system folder and creates the following registry entries:
HKCU\Software\Microsoft\Windows\CurrentVersion\Run\
DHCP Server
"regsvr.exe"
HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Run\
DHCP Server
"regsvr.exe"
HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\RunServices\
DHCP Server
"regsvr.exe"
W32/Rbot-PR spreads using a variety of techniques including exploiting weak passwords on computers and SQL servers, exploiting operating system vulnerabilites (including DCOM-RPC, LSASS, WebDAV and UPNP) and using backdoors opened by other worms or Trojans.
W32/Rbot-PR can be controlled by a remote attacker over IRC channels. The backdoor component of W32/Rbot-PR can be instructed by a remote user to perform the following functions:
start an FTP server
start a Proxy server
start a web server
take part in distributed denial of service (DDoS) attacks
log keypresses
capture screen/webcam images
packet sniffing
port scanning
download/execute arbitrary files
start a remote shell (RLOGIN)
Patches for the operating system vulnerabilities exploited by W32/Rbot-PR can be obtained from Microsoft at the following locations:
