A Study on RAT (Remote Access Trojan)
by Mirdul Sharma, Ranjeet K. Singh
RAT (Remote Access Trojan) is a malware that can control compromised System remotely and creates backdoors to steal data, using target system for illegal purposes etc. A RAT is always installed without victim’s knowledge by many means of communication like E-mail, online free app distribution, torrent, chatting messengers and many other means, Remote access Trojan usually hide its operation processes from the victim and from security software (Antivirus, firewall). RAT usually work on a server undetectably running and listening to TCP/UDP ports on an infected machine. A RAT is once installed, RATs play out their unforeseen or even unapproved activities and utilize a cluster of methods to conceal their follows to stay undetectable and keep on infected system for a long time. The main objective of paper is to provide awareness about remote access Trojans and how to detect a remote access Trojan and stay protected. A RAT is a zombie malware that sits on your system unassumingly waiting for you to input sensitive details like password’s, email accounts, logins to internet banking and more. In this papers I am going to show you how to disinfect an infected or compromised system and how to play safe while working on internet to stay away from RATs. But as we all know prevention is better than cure, so I am also going to show some methods to stay protected from these type of malicious programs that can be very dangerous for an individual as well as society.
