"These scams are increasingly difficult for customers to identify, as calls and e-mails appear to come from their banks' legitimate contact details," the bank said in a statement on Monday.
"With the rapid development of artificial intelligence, we have seen an alarming enhancement in spoofing techniques," said the bank's head of fraud risk management, Athaly Khan. "Current scams look and sound more real than ever before."
Fraudsters are using AI to access advanced technologies such as voice cloning, deepfake videos, chatbots and AI-generated phishing e-mails. This makes consumer awareness more critical than ever, Khan said.
