Understanding Remote Access Trojans (RATs)
Remote Access and Control are not entirely criminal. Tools for remotely accessing computers and servers have seen a significant rise in usage with the demands of remote work and digital transformation. However, Remote Access Trojans (RATs) pose a significant threat, allowing hackers remote control for illegal activities.
The Birth And Rise Of The RAT
The term "Trojan" references the mythological Trojan horse used in the Trojan War. RATs initially appeared in the '90s as playful tools for remote access, but evolved into malicious software over time. By 2010, more potent RATs like DarkComet and Gh0st emerged, expanding to target mobile OS like Android and iOS.
How Does A Remote Access Trojan (RAT) Work?
RATs work similarly to legitimate remote access tools but stay hidden to perform tasks without the user's knowledge. Hackers install RATs by tricking users into downloading the software, providing full control of the infected device. The privacy of victims is compromised by accessing cameras and microphones.
Who Are The Targets Of A Remote Access Trojan (RAT)?
While individuals can be targets, hackers focus on organizations with financial, political, or information gains. RAT attacks target financial institutions, governments for political manipulation, and corporations for valuable data. RATs enable attackers to anonymously commit crimes using infected networks.
How Do Cyber Criminals Use RATs Against An Enterprise?
RAT attacks on organizations start with cyber attacks like malspam or phishing to install the software. RATs disguise themselves using legitimate services like RDP, potentially remaining undetected for extended periods. Examples of recent RAT attacks include RomCom, Alchimist, and Cloud9 targeting different systems for malicious activities.
How To Detect A Remote Access Trojan (RAT) Infection
Detecting RAT infections can be challenging, as they may go undetected by anti-malware software. Signs of a RAT infection include overall system lag and frequent crashes of antivirus software. Regular scans for Trojans and monitoring system performance can aid in detection.
