W32/Rbot-NZ is a network worm and IRC backdoor Trojan for the Windows platform. When first run the worm copies itself to the Windows system folder as sysmsvc.exe and creates the following registry entries to run itself on system startup:
HKLM\Software\Microsoft\Windows\CurrentVersion\Run
MsWindows SysDate = "sysmsvc.exe"
HKLM\Software\Microsoft\Windows\CurrentVersion\RunServices
MsWindows SysDate = "sysmsvc.exe"
The backdoor component joins an IRC channel where it awaits further commands from a remote user. The backdoor component can be instructed to perform the following functions:
start an HTTP server
start an FTP server
send email
log keypresses
capture screen/webcams
download/execute arbitrary files
start a port scanner
provide remote shell access (RLOGIN)
