ShinyHunters has successfully hit the big leagues.
ShinyHunters successfully disrupting exams, schooling, grading, government funded research projects, dissertation work, graduations, financial aid, financial loss, potentially immigration complications, and more, has elevated this from "a silly shenanigan" to "major national security incident" and being labeled as an attack on United States critical infrastructure.
If I had to guess, the FBI, NSA, CIA, DIA, CISA, ICE, and DOE are all involved due to the disruption of this.
This isn't the largest extortion campaign I've seen, but this is definitely in the top ten. This is what the kids call a "Certified Hood Classic".
