Re: It needs to hurt if you use a movie-prop instead of a reinforced wall
If you're the one choosing that, then yes, but the problem is that you're counting on somebody who told you the wall was solid concrete, when actually it was just thin plaster.
This is the state of computing today : Microsoft denies all responsibility if something goes wrong, anti-virus vendors do the same, everyone is functioning under "best effort" rules, and along the line, someone forgot the concrete.
Not to mention that it is not specified how the miscreants managed to get into position to encrypt the files. A click on a wrong link is not too far-fetched.
The real problem is that a defense contractor did not have sufficient intrusion detection. I'm guessing they had backups, but that won't keep the scum from publishing.
Security is hard, that's for sure.
