Remote Access Trojan Architecture & Mechanisms
Remote Access Tools (RATs) are legitimate administrative utilities designed to facilitate remote communication, management, and technical troubleshooting across enterprise devices. However, malicious actors repurpose these concepts into Remote Access Trojans (RATs) to gain unauthorized, persistent, and interactive command-and-control access over compromised operating systems.
📌 RAT Evolution in 2025-2026
Over recent years, the threat landscape has shifted from basic single-stage Trojans to modular, resilient backdoors. Modern threat actors leverage direct syscalls, in-memory reflection, and encrypted command channels (via Telegram bots, Discord webhooks, or DNS tunnels) to bypass endpoint detection.
