AsyncRAT has emerged as a notable Remote Access Trojan (RAT) used by threat actors for its robust capabilities and ease of deployment. It gained favor for its extensive feature set, which includes keylogging, screen capturing, and remote command execution capabilities.
Its modular architecture, typically implemented in Python, provides flexibility and ease of customization, making it a preferred tool of choice for cybercriminals. During Trend Micro investigation of AsyncRAT infections, we observed Python scripts playing a central role in the infection chain, automating various stages of the attack. The initial payload, a Windows Script Host (WSH) file, was designed to download and execute additional malicious scripts hosted on a WebDAV server.
