Threat actors are leveraging Large Language Models (LLMs) to automate hyper-personalized phishing campaigns, targeting the global financial sector with unprecedented velocity. By utilizing AI-driven reconnaissance and LLM-generated lures, attackers are successfully evading traditional keyword-based and template-matching detection mechanisms. This transition from bulk spam to automated precision targeting facilitates Business Email Compromise (BEC) 2.0 through deepfake audio/video assets and AI-optimized malware variants designed to bypass behavioral heuristics. The current attack velocity has reached one attempt every 19 seconds, significantly increasing the operational cost of defense for financial institutions despite improved SOC response speeds.
