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.
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.
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.

How does a RAT work on my computer?
In the aftermath of a successful installation, RAT establishes a direct connectivity to the command-and-control (C&C) server, which is owned by the hackers, by using the predefined open TCP port of the compromised computer. The C&C server creates a remote communication on the victim’s machine. The RAT also has the ability to connect with one or more C&C servers run by the intruders.
How can a RAT be avoided?
There are a number of tools, techniques and best practices that can be used to avoid a RAT attack. Below is a detailed list of them:
Why is it difficult to avoid a RAT?
It is sometimes difficult to avoid a RAT because the attackers use a binder to link a RAT with legitimate executable programs, which hampers the detector from finding it. Though RATs don’t show up in running processes, using a task manager to look for unfamiliar or unknown processes is a good practice.
Can a RAT slow down my computer?
Moreover, your system will not be slowed. However, your internet speed will slow down as RAT uses your bandwidth to work. A RAT can infect your computer for a number of years if it goes unnoticed. To get out of the RAT nightmare, using malware detection tools and antivirus scans can be helpful.
What are the consequences of installing remote access Trojans?
If attackers succeed in installing Remote Access Trojans say in power stations, traffic control systems, or telephone networks, they can gain powerful control over them and even take down communities, cities, and nations. In this regard, we remember the 2008 war between Russia and Georgia, when Russia used a coordinated campaign of physical and cyber warfare to seize territory from the neighboring Republic of Georgia.
What percentage of Georgia's internet was affected by the Russian invasion?

How does Snort intrusion detection work?
The intrusion detection mode operates by applying threat intelligence policies to the data it collects, and Snort has predefined rules available on their website, where you can also download policies generated by the Snort user community. You can also create your own policies or tweak the ones Snort provides. These include both anomaly- and signature-based policies, making the application’s scope fairly broad and inclusive. Snort’s base policies can flag several potential security threats, including OS fingerprinting, SMB probes, and stealth port scanning.
What is the best way to detect malware?
The best option, especially for larger organizations, is to employ an intrusion detection system, which can be host-based or network-based. Host-based intrusion detection systems (HIDSs), which are installed on a specific device, monitor log files and application data for signs of malicious activity; network-based intrusion detection systems (NIDSs), on the other hand, track network traffic in real time, on the lookout for suspicious behavior. When used together, HIDSs and NIDSs create a security information and event management (SIEM) system. SIEM is an incredibly beneficial part of a strong security regimen and can help to block software intrusions which have slipped past firewalls, antivirus software, and other security countermeasures.
How do remote access Trojans evade live data analysis?
One way in which Remote Access Trojans can evade the live data analysis NIDSs provide is by dividing the command messaging sent through the malware across multiple data packets. NIDSs like Zeek, which focus more on application layers, are better able to detect split command messaging by running analyses across multiple data packets. This is one advantage Zeek has over Snort.
