This is less than ideal, but honestly, I’ve worked in the industry long enough to totally see how it happens. Someone needed to take this somewhere, or send it to someone, and just copied it without giving a second thought to what would happen if it got lost.
“Now we can add Heathrow Airport to the list of locations with poor IT security, after a random stranger literally found its entire security blueprint on a USB drive that was literally lying in the street.”
I hope Heathrow is going through a thorough process to identify how this happened, and start looking at processes that eliminate the need for anyone to pass this type of data along using a thumb drive in the first place, and making sure it’s always encrypted in the second.
Talk about a scary Halloween story.
