Dolphin X Malware Adds AI Profiler to Rank and Prioritize High-Value Victims After Infection

Dolphin X is a newly identified Windows infostealer and remote access trojan that integrates an AI Profiler component designed to score infected machines and generate priority rankings for operators. The profiler analyzes telemetry from compromised systems, including application usage, browser domains visited, and installed software, to produce daily summaries that help attackers focus resources on the most valuable targets such as those with cloud access or sensitive tools. Dolphin X claims compatibility with over 300 applications, explicitly covering nine Chromium and Gecko browser families, more than 100 cryptocurrency wallet extensions, 65 desktop wallets, 10 password managers, and over 30 common cloud CLI tools. The malware targets files like .env configurations, SSH keys, cloud access tokens, browser sessions, and cryptocurrency wallet data to accelerate movement from initial credential theft to further compromises in accounts and production environments. Researchers have confirmed the AI Profiler workflow and associated scoring functions in the operator panel, although the underlying AI model itself remains unverified without full analysis of an active sample. The discovery highlights how automated prioritization can significantly shorten the time between mass infections and targeted follow-on attacks, prompting recommendations for reduced local credential storage and enhanced behavioral detection.
