POLICE have released video footage of men they believe may be able to assist with their investigation into an ATM skimming syndicate.
Since the middle of January, detectives have noticed a marked increase in the incidence of ATM skimming throughout Sydney.
More than 40 ATMs have been targeted, including machines at Dural, Parramatta, Seven Hills and in the Sydney CBD.
Police said they believe those responsible are part of an organised group with links to Eastern Europe.
"The skimming devices the group are using are capable of copying card details while a tiny video camera records people entering their personal identification numbers," Detective Superintendent Arthur Katsogiannis, the commander of the Fraud and Cybercrime Squad, said.
"A copy of the compromised card is then created, with all of the capabilities of the original, allowing the group to access the account-holder's funds at liberty."
Cardholders need to be careful.
"Make sure you carefully cover the hand entering the PIN with your other hand, a newspaper or a magazine," the commander said.
"It's also important to regularly check your bank account transactions so that if you spot any suspicious withdrawals you can contact your financial institution before more money goes missing."
