Remote Access Trojan (RAT) – How to Detect and Remove It?

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.

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.

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.

documentA 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.

remote access to computerA 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!

hand-pointer1-right 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:

  1. 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.

  1. 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.



hand-pointer1-right 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.

View the running processes

Open your Task Manager by right clicking the taskbar and selecting Task Manager. Click the Processes tab, and scroll down to see if there are any processes with strange names (or abnormal CPU usage) running in your system. If you find one but can’t make sure whether it is a RAT’ process, you can search for it on Google. You may get the answer.


Check the startup programs

A RAT often adds itself to system startup directories and registry entries so that it can start automatically each time you boot your computer. Press Windows key + R key together. When a box appears, type msconfig.exe into it and click OK. When a window opens, click the Startup tab and check whethre there is any suspicious startup item. If there is, then Google it.


View the list of installed programs

You can access Control Panel first, and then click Add or Remove Programs or Uninstall a program option. A window will open and show all programs installed on your computer. If you notice any odd program, then it could be malicious. Similarly, if you are unable to recognize it, please type it into Google.

Check Internet connection

Another indication of the RAT infection should be the inexplicably slow network speed. If your computer is infected by a RAT, your Internet connection would be extremely slow, since the hackers will use the bandwidth to download or upload something. Surely, it cannot be directly inferred you must have a RAT on your PC when your network connection becomes slow, but you should pay attention to it. More early you find the problem, less loss you would suffer from.

Remove the RAT malware with SpyHunter

If you suspect that a RAT has infected your PC, you should disconnect your infected computer from the Internet first. RATs only work when the infected computer can get online, so you disconnecting your computer from the Internet can avoid the remote hackers to take control over your PC. Then, you can use another clean computer to download and install an advanced anti-malware program to exterminate the RAT. As we have mentioned above, a general anti-malware program would not be able to detect and remove a RAT, so you have to choose a real powerful one. Here is a tool that should help clean up the threat hiding in your system – SpyHunter, a tool providing real-time blocking and tailored solutions to fit your malware needs
