W32/Rbot-NY is a network worm and IRC backdoor Trojan for the Windows platform.
When first run W32/Rbot-NY copies itself to the Windows system folder as crsss64.exe and creates the following registry entries to run itself on system startup:
HKLM\Software\Microsoft\Windows\CurrentVersion\Run\
CRC Value Verifier = "crsss64.exe"
HKLM\Software\Microsoft\Windows\CurrentVersion\RunServices\
CRC Value Verifier = "crsss64.exe"
HKCU\Software\Microsoft\OLE\
CRC Value Verifier = "crsss64.exe"
W32/Rbot-NY spreads through various operating system vulnerabilities and through network shares protected by weak passwords.
The backdoor component allows an attacker to control the infected computer and offers functions such as:
Keystroke logging
Distributed denial of service attacks
Packet sniffing
Remote login
Video capture
File transfer
Proxy server
