Up, up, and away to the judge.

Delta Airlines is suing [24], a customer service tech vendor, over a 2017 passenger data breach.

Delta claims the company had a fault that's virtually infamous in the cybersecurity world: weak passwords.

Skift covered the lawsuit details:

The carrier wants to recover "millions of dollars in costs" it spent investigating the breach, notifying its customers, and paying for free credit monitoring products for affected passengers.

The artificial intelligence company apparently didn’t show much natural intelligence.

It let many employees use the same login to its systems.

Its passwords were weak.

What’s more, the company didn’t use second-factor or multi-factor authentication, which is a common safeguard that prevents knowing a simple password from being enough for a user to gain access.
