In Plain Terms
Voice phishing ("vishing") scams trick people over phone or audio channels and are hard to catch in real time. The authors built VishGPT, an AI system that listens to calls and flags vishing attempts as they happen, trained partly on synthetic data to overcome the shortage of real examples. It detected scams more accurately than existing methods (about 86% accuracy), offering a practical defense for users and security teams.
