Categories: Trojan,Backdoor,RAT,Downloader
This loose category includes a variety of Trojans that damage victim machines or threaten data integrity, or impair the functioning of the victim machine.

Multi-purpose Trojans are also included in this group, as some virus writers create multi-functional Trojans rather than Trojan packs.
Backdoors are the most dangerous type of Trojans and the most popular. Backdoors open infected machines to external control via Internet. They function in the same way as legal remote administration programs used by system administrators. This makes them difficult to detect.

Backdoors are installed and launched without the consent of the user of computer. Often the backdoor will not be visible in the log of active programs.

Once a backdoor has been successfully launched, the computer is wide open. Backdoor functions can include:

• Launching/ deleting files


• Sending/ receiving files


• Deleting data


• Displaying notification


• Rebooting the machine


• Executing files

Backdoors are used by virus writers to detect and download confidential information, execute malicious code, destroy data, include the machine in bot networks and so forth. Backdoors combine the functionality of most other types of in one package.


Backdoors have one especially dangerous sub-class: variants that can propagate like worms.
Many trojans and backdoors now have remote administration capabilities allowing an individual to control the victim's computer. Many times a file called the server must be opened on the victim's computer before the trojan can have access to it.

These are generally sent through email, P2P file sharing software, and in internet downloads. They are usually disguised as a legitimate program or file. Many server files will display a fake error message when opened, to make it seem like it didn't open. Some will also kill antivirus and firewall software.

Some RAT trojans are pranks that are most likely being controlled by a friend or enemy on April Fool's day or a holiday. Prank RATS are generally not harmful, and won't log keystrokes or hack. They usually do whimsical things like flip the screen upside-down, open the CD-ROM tray, and swap mouse buttons. However, they can be quite hard to remove.
This family of Trojans downloads and installs new malware or adware on the computer. The downloader then either launches the new malware or registers it to enable autorun according to the local operating system requirements.

The names and locations of malware to be downloaded are either coded into the Trojan or downloaded from a specified website.
