Regarding "Black Eye" from Q, this article details what this may actually be.
From the article:
The event offered a dress rehearsal for nascent technologies in a three-year-old DARPA research effort dubbed RADICS, short for "Rapid Attack Detection, Isolation and Characterization Systems."
The RADICS program, which kicked off in 2015 with a $77 million federal funding announcement, is aimed at ensuring U.S. utilities can bounce back from a blackout brought on by a cyberattack. Grantees had to assume the worst: that utilities' operational networks, including sensitive field equipment, have been compromised by hackers.
