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.
Why do attackers use remote devices?
Instead of storing the content on their own servers and cloud devices, attackers use targeted stolen devices so that they can avoid having accounts and servers shut down for illegal content.
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.
Why do attackers use RATs?
RATs have the same remote-control functionality as RDPs, but are used for malicious purposes. Attackers always code software to avoid detection, but attackers who use a RAT risk being caught when the user is in front of the device and the mouse moves across the screen. Therefore, RAT authors must create a hidden program and use it when the user is not in front of the device. To avoid detection, a RAT author will hide the program from view in Task Manager, a Windows tool that lists all the programs and processes running in memory. Attackers aim to stay hidden from detection because it gives them more time to extract data and explore network resources for critical components that could be used in future attacks.

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.

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.
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.
