Haha, wow. Treasury just sanctioned 3 Chinese nationals for allegedly running 911S5, a giant botnet that was sold for about a decade as one of the most reliable and cheapest proxy services for routing your traffic through someone else's (infected) machine.
One of the guys sanctioned by Treasury today I named as the apparent head of 911S5 in China, in a 2022 deep dive on this venerated proxy service. 911S5 imploded less than a week later, saying it had been massively hacked and that all user data was wiped.
