What Is a Remote Administration Tool (RAT)? How Do Stay Safe from It?
Remote administration refers to using a remote connection to manage or access any device. Tools for remote administration are referred to as remote administration software. Therefore, RAT allows someone to access your device remotely in the same way that you would physically, but from a different place.
These tools allow unauthorized users to view your files, and camera and even switch off your device. Server and client technology is the foundation of it. The main computer used to connect to the clients utilizing this software is called the server.
Who utilizes RAT?
Sometimes a technical person will remotely access our computer via the internet to fix a problem with our system.
But a lot of these remote administration tools are also used by hackers to break into your computer, take sensitive data from it, and damage your data. Usually, malicious code is attached by hackers to a game or movie that you download, allowing them to quickly get access to your machine.
How RATs are useful to hackers?
An advanced persistent threat is a method of persistent, covert hacking that aims to amass data over time rather than harm information or systems (APT). Because they are so adaptive and do not instantly start deleting data after installation or slow down a computer's performance, remote access Trojans are an effective tool in this kind of attack.
In contrast to other virus types like key loggers and ransomware, which essentially hold a computer or files hostage until the hacker is paid, Remote Access Trojans provide hackers complete administrative authority over the compromised system, so long as they manage to avoid detection.
This can result in awkward circumstances, as you might expect. For instance, the login credentials for bank and credit card accounts can be easily obtained using a Remote Access Trojan with a key logger. When combined, these techniques can be used to covertly access private photographs and documents, and turn on a computer's camera, and microphone. They can even use your home network as a kind of proxy server, allowing a hacker to carry out their activities mostly unnoticed and discreetly.
Remote access trojans can also be employed for more overtly criminal purposes. Due to the administrative access they grant, hackers are able to wipe hard drives, download unlawful content at their discretion, and even pose as you online. This might have geopolitical effects. Hackers have the capacity to devastate entire cities, towns, and even entire countries if they are able to implant Remote Access Trojans in critical infrastructure areas like power plants, traffic control systems, or telephone networks.
Protection against RAT
The easiest strategy to avoid Remote Access Trojans is to avoid downloading files from dubious sites, despite the fact that this may sound obvious or straightforward. Avoid downloading files from odd websites and never accept email attachments from senders you don't know (or even from known contacts if something about the message appears weird or suspicious). It's also critical to maintain patched and current operating systems and web browsers.
RAT and Hackers
It takes a lot of time to develop new Remote Access Trojans that can elude detection; thus, it usually makes more sense for hackers to use them against bigger targets like corporations, financial institutions, and governments. Antivirus programs like Malwarebytes and Kaspersky, which are both excellent RAT detectors and are constantly upgrading their databases of known security risks, can often be helpful for home and small business networks. However, if users are actively downloading and running illegal content, antivirus software won't be of much use.
When you try to scale up security practices, things get more challenging. While it's quite simple for one person to keep an eye on their computer activity and avoid clicking any suspicious links, larger firms or enterprises provide more variables, including the level of security awareness that each end user inside the organization brings to the table. It's always a good idea to provide users with ongoing security education. Still, administrators should take further precautions if they need to identify RATs on PCs connected to a network.
The fact that reports of Remote Access Trojans evading detection for years on workstations and networks persist shows that antivirus software isn't perfect and shouldn't be regarded as the gold standard for APT defense. RATs can easily go undetected among the numerous processes that parallel applications produce, and if they use rootkit techniques which can hide an incursion or obstruct technologies created particularly to find malware they might be challenging to get rid of. The only surefire way to get rid of Remote Access Trojans is to format a computer or server, despite the dramatic measure's inconvenience, especially if the malware has spread to several devices.
Type of Network to be used against RAT
The ideal choice is to use an intrusion detection system, which can be network-based or host-based and is especially useful for larger enterprises. Network-based intrusion detection systems (NIDS), on the other hand, track network traffic in realtime, on the lookout for suspicious activity. Host-based intrusion detection systems (HIDSs), which are installed on a specific device, monitor log files and application data for signs of malicious activity. A security information and event management
(SIEM) system is created when HIDSs and NIDSs are utilized in tandem. A strong security routine should include SIEM, which can help stop software intrusions that have passed firewalls, antivirus programs, and other security safeguards.
Larger businesses also require a method to safeguard their email data and information, particularly managed services providers (MSPs).
Conclusion
APTs are all terrible news, but Remote Access Trojans are particularly harmful. While there are a number of measures, such as security awareness training and antivirus software, that can be useful depending on the size of the environment you're trying to protect, intrusion detection systems are your best bet for stopping a Remote Access Trojan from slipping past your security setup.
The most efficient way to completely cover your environment is to combine a hostbased intrusion system with a network-based one. This combination makes it possible to quickly identify any odd or suspicious activity in configuration modifications and root access on your monitored devices as a potential security issue. It also makes it possible to identify suspicious activity in network traffic flows.
