Security vs convenience. The trade-offs. Some things may be worth it while others are much more questionable. I don't get the obsession to make almost anything and everything internet-connected.
Basically if it is internet-connected it gives the impression of moving forward. This can actually make things more efficient indeed, problem is most of these service providers (I'm not specifically talking about ISPs you know) don't provide proper security infrastructures alongside with these modernization steps. Take a look at AVs, they add cloud functionalities to enhance their detection rate, but the software itself is not securely coded and the connection to their servers is prone to MITM. We all are forced to swallow garbage just because they are too lazy and/or too clueless to gain and maintain cyber security while these modernizations can be made better.
No it doesn't. The way ATMs are built from the inside out are like tanks. They could run Windows 95 for all I care, the actual computer is only a fraction of what makes ATMs tick. Just watch Aussie50's tear down of one and be blown away: https://www.youtube.com/watch?v=duwl_UXvH6c This is why skimmers that fit OVER the points of entry are more common than actually trying to break into them.
