I think the real question is “what is the physical security model of the OS/2?”
I would imagine a determined attacker could infiltrate the system in-person. The question then becomes - how easy is it to compromise the system given physical access? And, assuming total compromise, how much damage and loss of life can be caused? (Do the subways have physical fail-safes?)
- flomo 7y agoOS/2 was a single user PC OS, it didn't have any physical security or account passwords or etc.
- tw04 7y agoCountless ATMs ran it for decades. They obviously figured something out to secure it.
- meowface 7y agoI wouldn't be so confident about that.
- nickpsecurity 7y agoCameras, locks, and obfuscation, basically. Ti hack it, you need to be alone with it long enough to find the flaws, figure out how dispensor works, etc. People hardly ever try to bypass them. Recently, hackers have been buying, studying, and hacking ATM's. They're not secure. You can see them in action searching for DEFCON ATM hacking on YouTube.
- Wowfunhappy 7y agoWouldn't that be true of a mechanical system as well? We need a way to deal with this. It doesn't make sense to change out the OS of something like a subway system every five years or so.
