Scammers, hackers, and fraudsters are taking advantage of artificial intelligence to launch more convincing phishing emails, malicious calendar invites, and phone scams targeting both bank customers and the institutions themselves. Banks are using AI to detect suspicious activity, but the battle is constant as criminals find new ways to stay one step ahead.

Why it matters

The rise of AI-powered fraud is a major threat to the banking industry, exposing customers and institutions to significant financial losses and reputational damage. Banks must stay vigilant and educate both employees and customers to combat these evolving fraud tactics.

The details

Phishing scams are a top threat, with AI making the emails more believable. Malicious calendar invites that bypass email filters are a new tactic, luring victims to click on infected attachments. Phone scams that spoof bank numbers are also common, pressuring customers to share sensitive information. Banks are using AI to detect anomalies, but fraudsters continuously find new workarounds.

  • In Q4 2025, a new wave of malicious meeting invite scams began appearing.
  • Phishing scams have been an ongoing issue, but AI is making them more sophisticated.

“Once you let your guard down and provide information you shouldn't, it is too late.”

“It's everywhere and has been directed at every bank in the state.”
