Still trying to figure out why banks and ATM manufacturers would use something so oversized, vulnerable and cumbersome as a full blown PC OS to do something so simple. And of course using an OS like XP opens up a world of vulnerabilities for hackers to exploit. Makes one wonder who is making what decisions and why.
XP has several versions that are specialized for particular applications. They’re almost certainly using a variety of the “kiosk” version, ehich is quite a bit less bulky than the ordinary workstation version. You have to dig pretty deeply into the MS software catalog to find it, but it’s there.
And yes, it’s stupid that these machines are still running XP in this day and age. They should long ago have been upgraded, or replaced with a more dedicated OS. It’s not like they need a huge amount of horsepower from the OS. A smartphone could provide the functionality for even a complex ATM these days, and it would look nicer too.
