Categories: Trojan,Backdoor,DoS
This category includes a variety of Trojans that damage victim machines or
threaten data integrity, or impair the functioning of the victim machine.
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.
These programs attack web servers by sending numerous requests to the specified server,
often causing it to crash under an excessive volume of requests.
DoS trojans conduct such attacks from a single computer with the consent of the user.
Worms can carry a DoS procedure as part of their payload.
