Hospitals are being warned about the rise of "vishing," a form of cybercrime utilizing artificial intelligence, as highlighted by Scott MacLean, CIO of MedStar Health, during congressional testimony. Hackers use AI to mimic individuals' voices for voice phishing attacks, posing significant challenges to healthcare providers' cybersecurity measures. This comes in response to an Enea report indicating a significant increase in vishing, alongside smishing and traditional phishing, particularly after the introduction of technologies like ChatGPT, emphasizing the evolving nature of cyber threats facilitated by advanced AI.
