What is Agent Tesla RAT

Agent Tesla is a sophisticated piece of malware that has been a significant threat in the cybersecurity landscape since its first appearance in 2014. It is classified as a Remote Access Trojan (RAT), which means it allows attackers to remotely control an infected computer. Over the years, Agent Tesla has evolved, incorporating various features that make it a potent tool for cyber espionage and data theft. This article delves into the history, features, infection methods, and removal techniques of Agent Tesla RAT. Agent Tesla is a multi-functional RAT with a wide range of capabilities. It is written in .NET and can perform keylogging, clipboard capture, and screen capturing. Additionally, it can extract credentials from various applications, including web browsers, email clients, VPNs, and FTP clients. The malware can also disable system utilities like Task Manager and Control Panel to evade detection and removal. The data stolen by Agent Tesla is usually encrypted using the Rijndael algorithm and encoded with a non-standard base64 function before being transmitted to a command-and-control (C&C) server. This ensures that the exfiltrated information remains confidential even if intercepted during transmission.

Agent Tesla primarily spreads through phishing emails containing malicious attachments or links.

The malware has been observed using various file formats for distribution, including Microsoft Office documents that exploit macro functionality and vulnerabilities like CVE-2017-11882. Another notable method of infection is through the use of malicious websites that sell the RAT under the pretense of a legitimate service.
