Islanders are being warned about a new scam in which fraudsters pretend to be bank staff or members of bank fraud teams.
The Jersey Financial Services Commission said it has become aware of cold-calling scams targeting people in the island.
The callers claim to represent banks and may ask for sensitive security information, including one-time passcodes, in an attempt to gain access to online bank accounts.
The JFSC is urging people to be cautious of unexpected phone calls and never share personal, banking or security details, including passwords and PIN codes, with anyone over the phone.
The regulator stressed that genuine banks will never ask customers to reveal such information during a phone call.
The JFSC said fraudsters may use genuine names, cloned websites, copied branding and even AI-generated images or voices to appear legitimate.
Their aim is to convince people they are dealing with a real financial institution and pressure them into handing over money or personal information.
Warning signs of a scam can include requests for personal information, claims that urgent action is needed to prevent fraud, spelling mistakes, unusual payment methods, suspicious links and offers that appear too good to be true.
Anyone who believes they have been targeted is urged to contact their bank if a payment has been made, report the matter to the States of Jersey Police and notify the JFSC’s enforcement team on 01534 822000 or email enforcement@jerseyfsc.org.
