Ozone (Remote Access Trojan) – Malware

Overview

The Ozone RAT represents a significant threat in the realm of cyber espionage and malware distribution. This powerful tool is designed to grant unauthorized access to compromised systems, enabling attackers to perform a range of malicious activities remotely. Initially marketed as a legitimate utility for remote system administration, Ozone RAT has evolved into a favored instrument for cybercriminals seeking to exploit its advanced capabilities for illicit purposes. The transition from a benign tool to a weapon of cybercrime underscores the dual-use nature of technology and highlights the ongoing challenges in cybersecurity. Ozone RAT’s sophistication is reflected in its stealth and versatility. It operates through a series of well-crafted social engineering tactics, often distributed via SPAM campaigns. The malware disguises itself within seemingly innocuous attachments or links, tricking users into executing the payload. Once installed, Ozone RAT employs various techniques to maintain persistence and evade detection, including the use of fake SSL certificates and proxy configurations to redirect traffic and facilitate man-in-the-middle attacks. This method not only compromises system integrity but also exposes sensitive data to further exploitation.
