I'm eagerly awaiting the https://www.rekt.news/ writeup, which as of this moment is still missing. They have decent technical analysis, and certainly far more than the linked article.
Was going to post about rekt.news . I was surprised that I didn't learn about this hack from them. That site is golden, and reminds me to the early 90s era of the internet: Where you had tens of "defaced" web pages (private and government) every day.
