Malware is one of the most dangerous computer threats that users are facing today. With the development of technology, the number of malware continues to grow. Approximately 70 percent of malware consists of Trojans, the most easily deployable of which is Remote Access Trojan. A Remote Access Trojan (RAT) allows cyber attackers to do every thing they like on your computer, such as steal information from you or install other malicious software.
This type of Trojan is available for download from Internet’s black market, which means that a hacker doesn’t need to create his own RAT to attack the end users’ computers. Generally, a Remote Access Trojan sells for between $10 and $50. But the well-known RATs such as Dark Comets and Blackshades can sell for between $50 and $250. Some novice attackers might not know how to operate a particular RAT. But you know what? It is very easy to get tutorials on how to use a particular RAT to attack a targeted computer on the internet. Attackers only need to visit some partucular websites and forums to learn it. It is reported that, YouTube has estimated 30,490 instructional videos on how to use various Remote Access Trojans and Hack Forums has 15 million posts talking about RATs. Since these Remote Access Trojans are inexpensive and tutorial on how to use them are easy to get, they are widely downloaded and used by cyber criminals to perform malicious actions on many users’ computers.

How does a RAT work?
A Remote Access Trojan usually enters a targeted computer through game applications, freeware or email attachments in which cyber attackers have hided the executable files. Once a user runs the executable files unknowingly, this RAT installs itself in the system memory. Surely, the installation process of this Trojan is secret. The smart attackers can use a program (usually it is called a binder) to combine RAT with legitimate executable programs so that the RAT executes in the background while the legitimate programs run, leaving the victim unaware of the malicious activity. Then, they may start to set IP port numbers and defining the program’s behaviors, such as when it starts, what it’s called, how it hides, and when & how it communicates. Once done, the attacker will generate the Trojan program and trick the vicitm into running it. After being launched, the RAT program can directly communicate with the attackers by using a predefined TCP port and receive commands from them.
How dangerous is a RAT?
There is no doubt that a Remote Access Trojan is very dangerous, since it can do what is required by the attackers, such as deleting and modifying files, formating hard disks, uploading and downloading files, and dropping off other malware. But the most two dangerous features of the Trojan are content capturing and remote control.
A RAT can capture every screen and keystroke on the infected computer. If there is a microphone on the victim’s computer, the RAT can capture all the conversations; if the victim has a WebCam on the computer, the RAT can turn it on and capture videos. In a word, everything the victim does on the compromised computer can be recorded. As a result, the victim’s passwords, directory paths, medical records, drive mappings, bank account & credit card information, as well as personal communications could be revealed to the attackers. And the victim may suffer from problems like privacy being violated, identity theft, and money loss.
A RAT can also allow the attackers to remotely control the victim’s computer. This is denifitely a big problem. After obtaining the unlimited access to the infected computer, the attackers can do everything they like. They can modify or delete documents, send emails on behalf of the victim, gather intelligence on internal application flows and structures, transmit valuable bussiness reports to their own computers, or use the computer to attack other computers. You can imagine how terrible it is when you computer is infected by a Remote Access Trojan!
Kindly reminder: RATs are highly dangerous computer threats that you should avoid. To protect your PC, it is important that you invest an advanced anti-malware program that helps prevent infection by RATs. SpyHunter is your best choice. Click the button below to download it right now!
Examples of RAT:
There are many types of RATs, but the most polulars ones are Back Orifice and SubSeven. These two types of RATs can do everything—capture screen, sound, and video content, record keystrokes, steal passwords and open backdoor to remote hackers, etc. Now let’s take a brief look at these two popular RATs:
- Back Orifice:
The main features of this Trojan include keystroke logging, HTTP file browsing, registry editing, audio and video capture, password dumping, TCP/IP port redirection, message sending, remote reboot, remote lockup, packet encryption, and file compression. This Trojan allows the attacker to configure a host of server options, including TCP or UDP, port number, encryption type, stealth activities (which works better on Windows 9x machines than on Windows NT machines), passwords, and plugins.
- SubSeven:
This Trojan works as a key logger, packet sniffer, port redirector, registry modifier, and microphone and WebCam-content recorder. This Trojan allows the attackers to remotely swap mouse buttons; turn the Caps Lock, Num Lock, and Scroll Lock off and on; disable the Ctl+Alt+Del key combination; log off the user; open and close the CD-ROM drive; turn the monitor off and on; invert the display; and shut down or reboot the computer.
How can you detect and remove a Remote Access Trojan?
A RAT enables cyber criminals to perform a series of malicious activities on the victim’s computer, which could result in various severe problems. Therefore, it is really important that users learn how to detect and remove a RAT quickly. Generally, a common antivirus program is less likely to detect RATs than other types of malware like viruses and worms, because the attackers often use a binder to combine a RAT with legitimate executable programs, which hinders the scanner from finding it. But you still can try these ways to catch a Remote Access Trojan.
