Hackers affiliated with Anonymous stole a massive trove of data from NASA and attempted to bring down a $222 million drone, according to a report published over the weekend.

The group, called AnonSec, allegedly exfiltrated 276 gigabytes of data over several months. That included 631 videos from aircraft and weather radars, 2,143 flight logs, and the names, email addresses and phone numbers of 2,414 NASA employees. The group handed evidence of the attack over to InfoWars, which published the report on Sunday.
