Wow, so many good parts in this…
Side note: I do not do any coding professionally, just self taught stuff to impressive my business coworkers - but this was really well explained.
My favorites: Default username and password for accessing the debugger on the trains computer (that apparently can’t be changed)
Hard coded geofenced coordinates that would disable a train if it was being serviced at a competitors location
Absolute favorite: the incorrectly programmed date lock that would only disable the train November & December on the 21st-30th
Hopefully the company is reprimanded for this - here in the US it would probably be a slap on the wrist and nothing else.
Hmm, that’s good / reassuring - hopefully we don’t have to find out!
