Course Guides Bank and voice scams

How do bank and cloned-voice scams target law firms?

Scammers phone pretending to be the bank’s fraud team, with caller ID made to look genuine, and ask for a one-time code. Others clone a client’s voice to order a payment. Hang up and call the bank on a number you source yourself, and confirm client instructions by calling back on details already on file.

The bank that is not your bank

The Law Society’s Trust Account Department has seen a significant escalation in scammers calling, emailing or messaging lawyers and pretending to be from their bank. The scammers use technology to make a call appear to come from the bank’s phone number.

  • Your bank will never ask over the phone for online banking passwords, one-time security codes, PINs or tokens.
  • Contact your bank separately using your banking app or a number from the bank website, a statement or a card.
