Remote Access Trojan - GeeksforGeeks
History of Remote Access Trojan : This Remote Access Trojan popularity increased in the year of 2000s. In this period people didn’t have sufficient knowledge of how this virus spreads on the internet and what is antivirus?
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.
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. Unless you have monitoring configured on your computer, you won't know which data and files transferred to an attacker. You should always change passwords across all accounts, especially financial accounts, after removing malware from your system.
Can malware writers name processes?
For most applications and processes, you can identify any suspicious content in this window, but malware writers name processes to make them look official. If you find any suspicious executables and processes, search online to determine if the process could be a RAT or other type of malware.
How to protect yourself from remote access trojans?

What is a RAT trojan?
RAT trojan is typically installed on a computer without its owner’s knowledge and often as a trojan horse or payload. For example, it is usually downloaded invisibly with an email attachment, torrent files, weblinks, or a user-desired program like a game. While targeted attacks by a motivated attacker may deceive desired targets into installing RAT ...
What Does a RAT Virus Do?
Since a remote access trojan enables administrative control , it is able to do almost everything on the victim machine.
How does RAT malware work?
Once get into the victim’s machine, RAT malware will hide its harmful operations from either the victim or the antivirus or firewall and use the infected host to spread itself to other vulnerable computers to build a botnet.
Why is Darkcomet no longer available?
The reason is due to its usage in the Syrian civil war to monitor activists as well as its author’s fear of being arrested for unnamed reasons.
Why do RATs use a randomized filename?
It is kind of difficult. RATs are covert by nature and may make use of a randomized filename or file path structure to try to prevent identification of itself.

Is Sub 7 a trojan horse?
Typically, Sub 7 allows undetected and unauthorized access. So, it is usually regarded as a trojan horse by the security industry. Sub7 worked on the Windows 9x and Windows NT family of OSes, up to and including Windows 8.1. Sub7 has not been maintained since 2014. 4.
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.
How many remote access trojan families were there in 1996-2018?
Figure 1: Timeline of 337 well-known remote access trojan families during 1996-2018. They are ordered by the year in which they were first seen or reported by the community. The last decade clearly shows a significant growth compared with the previous 16 years.
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.
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.
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.
Do RATs support plug-ins?
To add more capabilities to the existing RAT, some malware authors rely on plug-ins. This is not a widely used capability, however the most popular RATs support plug-ins. Good plug-ins are craved by the cybercrime community. These plug-ins are one of the main differentiators in terms of cost in the underground market.
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.
Who was the law professor that was targeted by NetBus?
In 1999, someone downloaded NetBus and targeted Magnus Eriksson, a law professor at Lund University in Sweden. The attacker planted 12,000 pornographic images on his computer, 3,500 of which featured child pornography. The system administrators discovered them, and the law professor lost his job.
What is Gh0st used for?
Soon, they started to be used as part of more complex attacks by cybercriminals and state-sponsored attackers alike. There was a clear distinction between authors and operators, Valeros says. Gh0st was among the most prolific remote access trojans of its time.
What tools did RAT authors use in the 2000s?
In the 2000s, RAT authors were not naive kids who wanted to see how far they could go. Most of them were familiar with tools such as NetBus, SubSeven or Back Orifice, and they knew exactly what they were doing.
What was the Gh0st attack?
Gh0st is notorious for its part in the GhostNet Operation uncovered in 2009, which targeted political, economic, and media organizations in more than 100 countries. The attackers quietly infiltrated computer systems connected to embassies and government offices. Even Dalai Lama’s Tibetan exile centers in India, London, and New York City were hacked. According to several research papers, the malware collected information, encrypted it, and sent it to the command-and-control server.
Who created NetBus?
Yet, they were “innovative and disruptive,” Valeros says. NetBus, for instance, was created by Carl-Fredrik Neikter in 1998, and its name, translated from Swedish, means “NetPrank.”
Is NetBus a legit tool?
The developer claimed he didn’t want NetBus to be used maliciously, saying it was “a legit remote admin tool,” security researcher Seth Kulakow wrote in a paper he published with the SANS Institute. “However, if you didn’t already figure it out, it is still a very nice tool to use for the other purpose,” Kulakow wrote.
What is a Remote Access Trojan?
Sometimes referred to as a “remote administration tool” due to their similarity to legitimate IT admin tools like TeamViewer and LogMeIn, a remote access trojan is essentially a hidden backdoor into another user’s computer. This backdoor gives the person operating the RAT a whole range of different functions that can be used for malicious purposes, depending on which particular RAT platform they’re utilizing.
How Do Remote Access Trojans Spread?
As with most malware infections, RATs typically come through malspam, phishing and spearphishing campaigns. For example, a user may receive a phishing email carrying a malicious pdf or Word document, or the mail may contain a URL that takes the victim to a webpage for a fake software plugin and a message that a required tool is missing or needs updating. Adobe Flash, Adobe Reader and similar popular products are often spoofed for just this kind of trick due to their wide adoption across platforms.
How Do Threat Actors Use RATs Against The Enterprise?
While there’s certainly been cases of “lone wolf” actors targeting individuals and organizations and remaining undetected for over a decade, until recently the main threat to enterprise from RATs came from APT campaigns, including those targeting the most sensitive of installations such as a nuclear power plant in India (targeted by the DTrack RAT), oil and gas companies in the Middle East, telecoms across Africa and Asia ( DanBot RAT ), government agencies around the globe ( Calypso RAT ), and most recently an energy-sector organization in Europe ( PupyRAT ).
How Can CISOs Protect Against Remote Access Trojans?
In the past, RATs were difficult to develop and required a high degree of proficiency to operate. They were anything but “fire-and-forget” tools. They required threat actors to invest time and effort in inserting the malware into victims’ systems, manually operate the connection and then carry out whatever nefarious activities they had planned. As we have seen, things have changed more recently, and like other crimeware such as ransomware as a service, malware developers have seen and grasped the opportunity to make profit by selling easy access to tools that others do not have the skill to make for themselves.
How Do RATs Evade Detection?
RATS piggyback on the same remote access services that legitimate tools like TeamViewer use, exploiting Windows Remote Desktop (RDP) and TCP networking protocols to install a backdoor to the attacker’s own machine.
What is OLE in ODT?
In one of the campaigns targeting Microsoft Office users, the cybercriminals embedded an OLE (Object Linking and Embedding) in ODT documents to download the well-known remote access trojans (RATs).
Can ODT be used to target?
The two researchers believe that the use of less popular file formats such as ODT may increase the potential of specifically targeted attacks. Cybercriminals can check public records of organizations that switched to open-source Office suites and choose their targets from there.
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 ICS malware?
Malware targeting industrial control systems (ICS) is nothing new, with big names like Stuxnet and Industroyer designed to cause physical damage. However, some ICS-focused malware is targeted at controlling critical infrastructure.
What is PhoneSpector?
PhoneSpector offers the hacker the ability to monitor a wide variety of activities on the device. This includes monitoring phone calls and SMS messages (even those that were deleted) as well as app activity. PhoneSpector even provides a customer service helpline in case a hacker gets in a bind. 4.
How does PhoneSpector work?
One of these is PhoneSpector, which bills itself as being designed to help parents and employers but acts like malware. The software can be installed by getting the device owner to click on a link and enter a product key on their device. It then monitors the device while remaining undetectable to the user.
Is Androrat still used?
Despite the age of the source code (last update in 2014), AndroRAT continues to be used by hackers. It includes the ability to inject its malicious code into legitimate applications, making it easy for a hacker to release a new malicious app carrying the RAT.
Do remote access Trojans exist?
Many different Remote Access Trojans exist, and some hackers will modify existing ones or develop their own to be better suited to their preferences. Different RATs are also designed for different purposes, especially with RATs geared specifically to each potential target (desktop versus mobile, Windows versus Apple and so on).
