Delta Flights Grounded For Hours Due To Worldwide System Outage by Camila Domonoske.
From the post:
Delta flights around the world were delayed this morning due to a “computer outage,” the company says.
A power outage in Atlanta around 2:30 a.m. ET was responsible for the problem, the company said in a statement.
…
“We are aware that flight status systems, including airport screens, are incorrectly showing flights on time,” Delta says. Meanwhile, passengers attempting to check in online or through Delta’s app have reported seeing error messages.
The problem is “system-wide” and happening “everywhere,” the company has said.
….
No causes have been specified for the “power outage.”
But a good example of how imaginative hacking can bring down a worldwide transportation system, without ever breaching computer security.
Delta computer security is probably as good as airline security gets, but who needs root access when you can pull the power plug?
A real world denial of service (DoS) attack.
PS: How many degrees of separation does your computer security encompass?
