What are the key elements of a remote access trojan?
The two key elements of any remote access trojan are the client and the server . Additional elements may include the builder, plug-ins and crypter. In this context, a server is the program installed on the victim’s device, which is configured to connect back to the attacker. The client is the program used by the attacker to monitor and control infected victims: it allows the visualization of all active victim infections, displays general information about each infection, and allows individual actions to be performed manually on each victim.
What is remote access software?
Remote access software is a type of computer program that allows an individual to have full remote control of the device on which the software is installed. In this research we distinguish between remote access tool and remote access trojan. A remote access tool refers to a type of remote access software used for benign purposes, such as TeamViewer [1] or Ammyy Admin [2], which are common tools used by billions of users worldwide. Remote access trojans, referred to in this paper as RATs, are a special type of remote access software where (i) the installation of the program is carried out without user consent, (ii) the remote control is carried out secretly, and (iii) the program hides itself in the system to avoid detection. The distinction between tools and trojans was created by defenders to make clear the difference between benign and malicious RATs, however in the underground, attackers claim all RATs are remote access tools.
What is a builder in a RAT server?
The builder is a program used to create new RAT servers with different configurations. When attackers move infrastructure quickly, launch new attacks and require flexibility, builders save time and provide agility.
Who is the operator in a RAT?
The operator (s) is the actor who purchases the software (or a licence) and carries out the attacks. This actor has the knowledge of who the target is, the possible scams or attacks that can be carried out with the software, and which characteristics are needed when purchasing a RAT.
Why do attackers use crypters?
To be more efficient and hard to detect, attackers use crypters to make the RAT servers fully undetectable (FUD). Crypters are programs that take a given program, read the code, encrypt it with a key, and automatically create a new program that contains the encrypted code and key to decrypt it. Upon execution the key will be used to automatically decrypt the original program. Crypters are used to avoid detection by anti-virus engines.
When was remote access first used?
The oldest legitimate remote access software was built in the late 1980s, when tools such as NetSupport appeared. Soon after that, in 1996, their first malicious counterparts were created. NokNok and D.I.R.T. were among the first, followed by NetBus, Back Orifice and SubSeven.

How are Remote Access Trojans Useful to Hackers?
Attackers using remote control malware cut power to 80,000 people by remotely accessing a computer authenticated into SCADA (supervisor y control and data acquisition) machines that controlled the country’s utility infrastructure. RAT software made it possible for the attacker to access sensitive resources through bypassing the authenticated user's elevated privileges on the network. Having access to critical machines that control city resources and infrastructure is one of the biggest dangers of RAT malware.

How to install a RAT?
An attacker must convince the user to install a RAT either by downloading malicious software from the web or running an executable from a malicious email attachment or message. RATs can also be installed using macros in Microsoft Word or Excel documents. When a user allows the macro to run on a device, the macro silently downloads RAT malware and installs it. With the RAT installed, an attacker can now remotely control the desktop, including mouse movement, mouse clicks, camera controls, keyboard actions, and any configured peripherals.
What is remote control software?
Legitimate remote-control software exists to enable an administrator to control a device remotely. For example, administrators use Remote Desktop Protocol (RDP) configured on a Windows server to remotely manage a system physically located at another site such as a data center. Physical access to the data center isn’t available to administrators, so RDP gives them access to configure the server and manage it for corporate productivity.
What happens if you remove the internet from your computer?
Removing the Internet connection from the device disables remote access to your system by an attacker. After the device can no longer connect to the Internet, use your installed anti-malware program to remove it from local storage and memory.

What is Trojans program?
Trojans are programs that pretend to do one thing, but when loaded actually perform another more malicious act. Trojans gain their name from Homer's epic tale, The Iliad. To defeat their enemy, the Greeks built a giant wooden horse with a trapdoor in its belly. The Greeks tricked the Trojans into bringing the large wooden horse into the fortified city. However, unknown to the Trojans and under the cover of darkness, the Greeks crawled out of the wooden horse, opened the city's gate, and allowed the waiting solders in.
How do Trojans communicate?
Trojans can communicate in several different ways. Some use overt communications. These programs make no attempt to hide the transmission of data as it is moved onto or off of the victim's computer. Others use covert communications. This means that the hacker goes to lengths to hide the transmission of data to and from the victim. Many Trojans that open covert channels also function as backdoors. A backdoor is any type of program that will allow a hacker to connect to a computer without going through the normal authentication process. If a hacker can get a backdoor program loaded on an internal device, the hacker has the ability to come and go at will. Some of the programs spawn a connection on the victim's computer connecting out to the hacker. The danger of this type of attack is the traffic moving from inside out, which means from inside the organization to the outside Internet. This is typically the least restrictive, as companies are usually more concerned about what comes in the network as they are about what leaves the network.
How many types of Trojans are there?
The EC-Council groups Trojans into seven primary types, which is simply their way of organizing them. In reality, it's hard to place some Trojans into a single type, as many have more that one function. To better understand what Trojans can do, these types are outlined in the following list:

Why are remote access Trojans important?
Remote Access Trojans fulfill an important function for hackers. Most attack vectors, like phishing, are ideal for delivering a payload to a machine but don’t provide the hacker with the ability to explore and interact with the target environment. RATs are designed to create a foothold on the target machine that provides the hacker with the necessary level of control over their target machine.
What is the next step in a phishing attack?
Once a hacker has gained initial access to a target machine, expanding and solidifying that foothold is the next logical step. In the case of a phishing attack, this involves using malware to take advantage of the access provided by the email.
