Authorities in the Malaysian capital of Kuala Lumpur suspect that a rash of ATM hacking incidents over the weekend might involve staff working for banks and ATM vendors.
Thieves hacked into 17 ATMs in four large cities along Malaysia's southwest coast stealing more than 3 million ringgit ($916,450), according to a report by The Star.
Police said the ATMs were infected with Backdoor.Padpin malware, a Trojan introduced via the machine's CD-ROM drive. The attacker then uses the ATM PIN pad to submit commands to dispense cash.
As of yet, the involvement of insiders is only a theory, said a representative of the Commercial Crime Investigation Department.
"We are studying statements recorded from the complainants, security guards, bank staff and the ATM vendors," he told the publication. The report said that police also are looking at fingerprints left on the machines and working to identify suspicious ATM users captured by CCTV.
