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 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.
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 happens if you don't see malware in Task Manager?
If you don’t see any potential malware in Task Manager, you could still have a RAT that an author programmed to avoid detection. Good anti-malware applications detect most of the common RATs in the wild. Any zero-day malware remains undetected until the user updates their anti-malware software, so it’s important to keep your anti-malware and antivirus software updated. Vendors for these programs publish updates frequently as new malware is found in the wild.
How do RATs work?

What is a RAT?
A Remote Access Trojan (RAT) is a type of malware that allows covert surveillance, a backdoor for administrative control and unfettered and unauthorized remote access to a victim’s machine. The RAT is very dangerous because it enables intruders to get remote control of the compromised computer. Attackers can use the exploited machines to perform various malicious activities such as installing and removing programs, manipulating files, hijacking the webcam, reading data from the keyboard, harvesting login credentials and monitoring the clipboard.
Why are RATs so difficult to detect?
This is partly because RATs are starting to behave in ways that many firewalls and other cybersecurity tools don’t perceive as malicious. For instance, they leverage legitimate network ports on infected endpoints, which is a common enough action that most security tools won’t flag it. What makes all of this particularly troubling is the ease with which RATs can be procured. Today, hackers on the dark web will sell these as ready-made intrusion tools.
What is the most effective way to steal large amounts of data?
Hackers have long-since realized that advanced persistent threats (APTs) such as this new RAT are the most effective way to steal large amounts of data.

Researchers believe that Sakula, a RAT that maintains persistence through a registry Run key, was involved.

Adversarial abuse of remote monitoring & management (RMM) software is not new, but—given the rash of costly and destructive ransomware attacks in recent months and years—it’s particularly important that security teams develop robust security controls for detecting malicious use of RMM tooling. In fact, just last week AdvIntel reported on adversaries who—after gaining initial access—had installed an RMM tool called Atera and used it as a functional backdoor in the lead up to a Conti ransomware outbreak.

What is intrusion detection?
Intrusion detection systems are important tools for blocking software intrusion that can evade detection by antivirus software and firewall utilities. The SolarWinds Security Event Manager is a Host-based Intrusion Detection System. However, there is a section of the tool that works as a Network-based Intrusion Detection System. This is the Snort Log Analyzer. You can read more about Snort below, however, you should know here that it is a widely used packet sniffer. By employing Snort as a data collector to feed into the Snort Log Analyzer, you get both real-time and historic data analysis out of the Security Event Manager.

This dual capability gives you a full Security Information and Event Management (SIEM) service. This means that you can watch Snort-captured events live and also examine cross-packet intrusion signatures identified through log file records.
How does Beast RAT work?
The Beast RAT attacks Windows systems from Windows 95 up to Windows 10. This uses the same client-server architecture that Back Orifice pioneered with the server part of the system being the malware that gets installed surreptitiously on the target computer. Once the server element is operational, the hacker can access the victim computer at will through the client program. The client connects to the target computer at port number 6666. The server is also able to open connections back to the client and that uses port number 9999. Beast was written in 2002 and is still widely in use.
