NSW Police has released images of three men after skimming devices were found in January in ATMs at Hurstville, Chatswood and Burwood.
Police believe a group is targeting ATMs by attaching skimmers and video cameras to the machines.
The Fraud and Cybercrime Squad is urging people to cover the keypad when using their PINs, check their credit cards for any irregularities and report suspicious activity at ATMs.
Anyone with information should contact Crime Stoppers on 1800 333 000.
