Threat actors are using a fileless variant of AsyncRAT, targeting German-speaking individuals with a deceptive verification prompt. This prompt misleads users into executing harmful commands. The malware employs obfuscated PowerShell scripts to operate in memory without creating files on disk, complicating detection by antivirus solutions. The attack begins with a fake verification page prompting users to click "I’m not a robot," which copies a malicious command to the clipboard. This command uses conhost.exe to run a hidden PowerShell instance that retrieves a payload from a remote server. The malware establishes a connection to a command-and-control server and maintains persistence through registry keys, enabling remote control and data exfiltration. Key tactics include stealth execution, in-memory C# compilation, and TCP-based communication over non-standard ports. The campaign has been active since at least April 2025.
