Summary
A remote administration utility tool (RAT) that allows a user to access and control a computer or mobile device, usually remotely over a network or the Internet.
Removal
Based on the settings of your F-Secure security product, it will either move the file to the quarantine where it cannot spread or cause harm, or remove it.
A False Positive is when a file is incorrectly detected as harmful, usually because its code or behavior resembles known harmful programs. A False Positive will usually be fixed in a subsequent database update without any action needed on your part. If you wish, you may also:
Check for the latest database updates
First, check if your F-Secure security program is using the latest updates, then try scanning the file again.
Submit a sample
After checking, if you still believe the file is incorrectly detected, you can submit a sample of it for re-analysis.
Note: If the file was moved to quarantine, you need to collect the file from quarantine before you can submit it.
Exclude a file from further scanning
If you are certain that the file is safe and want to continue using it, you can exclude it from further scanning by the F-Secure security product.
Note: You need administrative rights to change the settings.
Technical Details
While backdoors can be used for legitimate activities by authorized administrators, they can also be used by attackers to gain control of a computer or device without the knowledge or consent of its user or administrator.
Installation
A typical backdoor consists of 2 components - the server program, which can be installed on multiple computers, and the client program that can be used to control one or all the servers.
Attackers can distribute copies of the server program to potential victims in numerous ways - for example, as part of the payload for a worm or trojan; as a disguised file attached to a spam email; as a file shared on peer-to-peer (P2P) networks, and so on.
Attackers typically rely on either social engineering or exploiting a vulnerability to install the backdoor on a computer. Once the server program is installed, it will open a network port and communicate with the client program. An attacker can then use the client to issue commands to the machine.
Impact
A backdoor is usually able to gain control of a system because it exploits undocumented processes or features in an operating system or installed program. Depending on how sophisticated a backdoor program is, it can perform actions such as:
- Sending and receiving files
- Getting system information
- Changing the system settings
- Taking screenshots
- Playing tricks like opening and closing the DVD drive
and so on.
