Viceroy Tiger, also known as Donot, is an espionage-focused threat actor assessed to operate from India. The group has been reported targeting military and defense-related personnel in Bangladesh and has used document-based intrusion techniques including remote template injection to deliver multi-stage shellcode loaders. Public reporting has associated the actor with targeted operations against government and defense interests, consistent with intelligence collection objectives rather than financially motivated crime. Viceroy Tiger is tracked under the Donot name by multiple vendors, and reporting has linked it to spearphishing-style delivery, staged malware execution, persistence, and post-compromise collection and exfiltration activity typical of a long-running state-aligned intrusion set.
