Reverse Engineering Malware: A Deep Dive
Introduction Reverse engineering malware is a critical skill for security researchers, threat analysts, and incident responders. By dissecting malicious software, we can uncover its true capabilities, identify vulnerabilities, and develop more effective countermeasures. In this post, we will conduct a deep analysis of a real-world malware sample using Ghidra, an open-source reverse engineering tool widely used by professionals in the field. Selecting the Malware Sample For this analysis, we have chosen Agent Tesla, a well-known keylogger and Remote Access Trojan (RAT) that has been actively used in cyber espionage campaigns. Typically delivered through phishing emails, Agent Tesla has targeted businesses and individuals alike, often masquerading as legitimate software attachments to evade detection. Our goal is to reverse engineer this sample to understand its inner workings and identify potential indicators of compromise (IoCs). Setting Up the Analysis Environment Before analyzing the...
