the rise of mixer services that essentially launder funds

Not really. It's just truly anonymous. The hackers didn't shuffle the money around like they should have because once they start breaking that deposit up and transferring it from wallet to wallet, it becomes effectively lost except to the wallet holders. That plus not using truly anonymous ways of dealing with bitcoin - current resources on the internet make it far too easy to track cryptocurrency exchanges. If you use anonymous sources, it can't be tracked. I'm betting the hackers just got lazy or didn't know what they were doing.
