Security researchers have discovered a new malware program that infects automated teller machines (ATMs) and allows attackers to extract cash on command.

The program is dubbed GreenDispenser and was detected in Mexico. However, it’s only a matter of time until similar attacks are adopted by cybercriminals in other countries, researchers from security firm Proofpoint said in a blog post.

GreenDispenser is not the first malware program to target ATMs. In October 2013, security researchers from Symantec warned about a backdoor called Ploutus that could infect ATMs when a new boot disk is inserted into their CD-ROM drives.
