....if you think that "viruses" are only affecting Mexico's cash dispensing machines, think again!
There are a whole host of malware and viruses affecting banking machines Globally: in addition to plotus (a seemingly Latin American phenomenon), there are DMGs (dump memory grabbers), and Dexter. DMG have affected point of sale locales associated with 4 of America's largest banks...I (personally) assume that ALL POS (point of sale) and ALL ATM machines are infected, and only do cash withdrawals with a human teller at a bank (no matter what country). Your mileage may vary with my thinking (ie. do your own due diligence).
A good source to keep up with financial system compromise, is Security Week (enterprise security analysis),
here-->...but a warning: the more you read and know, the more you'll wish the World had never gone digital banking & personal and corporate digital info :B
This virus should be fixed soon, I hope.
...just when you think that this is the case, 100 or 200 new variants infect machines in more countries globally.
Have fun, and don't lose too much sleep over it,
