Hacking an ATM machine has become easy as instructions can be found on the internet, says a security expert.
"It's now terribly easy to hack an ATM machine," says Prinya Hom-Anek, Thailand Information Security Association's vice-president. "You can find instructions on YouTube."
More valuable pieces of information are commonly traded – or put up for sale – among hackers on the dark web.
The ATM hacking methods shared online truly work, Mr Prinya added.Criminals use "malware", a malicious software, which they introduce to the ATM's computer system to give them full access and authority over the machine.
"In a way, the hackers become administrators of the ATM's computer," he explained. "They can order it to perform any tasks, including spilling out banknotes."
Only a month after criminals made off with the equivalent of US$2.2 million (76 million baht) in a major ATM theft in Taiwan, the Government Savings Bank (GSB) revealed on Tuesday it had fallen victim.
