ATMs in Taiwan were spewing money over the weekend in what authorities believe were malware-aided thefts, according to Softpedia.

More than $2 million (£1.5m) was stolen in a series of heists in the cities of Taipei and Taichung targeting branches of Taiwan's First Commercial Bank and its ATMs. 

Nearly a thousand ATMs at a number of banks in the country were shuttered while officials examined the equipment, manufactured by Wincor Nixdorf, a German firm that provides banking hardware, software and services. The ATMs were scheduled to go back online on 13 July.

Authorities identified two individuals on surveillance video hitting a number of ATMs and a number of individuals are being questioned, including bank clerks, the security personnel responsible for filling the ATMs, as well as maintenance engineers. An insider is suspected of installing the malware.

One of the suspects was identified by Taiwanese officials as a Russian national.
