And Dino you mean they crash the price of Apple stocks to buy cheap coins nom nom nom ?
No, they have nothing to do with crypto. They just had to:
1) announce publicly that there would be a serious hacking on Apple
2) make that announcement look silly as can be so that Apple doesn't act upon it
3) attract sufficient buzz so that this news is clearly publicly known
Next, if they really know how to do what they say, they DO it. Apple looks like the biggest of fools. Apple share falls like a stone on april 7. The guys have shorted Apple shares on the stock market the 5th. They cash out on the 8th of April.
The SEC wonders how they could know, they say they are simply speculators acting upon the public announcement of the menace (hence the need for (1) and (3)), and the fact that Apple didn't take them seriously and didn't pay the ridiculously low ransom (hence (2)).
Otherwise, if hackers shorted massively shares, they give away that they are the hackers. But now, the information is open to everybody so they can pretend just to be astute speculators in the stock market. Nothing crypto.
They simply needed to look totally ridiculous to Apple and to most market watchers.
