ProRat is a Microsoft Windows based backdoor trojan horse, more commonly known as a RAT (Remote Administration Tool). As with other trojan horses it uses a client and server. ProRat opens a port on the computer which allows the client to perform numerous operations on the server (the machine being controlled). ProRat is available in a free version, and a paid version. In the free version, ProRat cannot connect to users over wide area networks (WANs), only over LANs (Local Area Networks). ProRat is known for its server to be almost impossible to remove without up-to-date antivirus software.
ProRat allows many malicious actions on the victim's machine. Some of its abilities include:
- Logging keystrokes
- Stealing passwords
- Full control over files
- Drive formatting
- Open/close CD tray
- Hide taskbar, desktop, and start button
- Writing on-screen
- Movement of cursor
- Take screenshots
- View system information
- View webcam
- Download & run files
- Password Protect your bound server from being used by anyone else
ProRat has a server creator with features that allow it to be undetected by antivirus and firewall software, and also allow it to stealthily run in the background. The software runs completely (including rootkit) in Windows 2000/XP, and such features include killing security software, removing and disabling system restore points, and displaying a fake error message to mislead the victims.
It is often "Bound" with other file types, such as image files, and when the image file is viewed, the server is installed in the background, undetected if no antivirus software has been installed.
