Why not? People link their wallets to other wallets and financial services with reporting requirements all the time. Bitcoin isn't anonymous

All transactions are public on the Bitcoin blockchain. I haven't followed the wallets, but it's possible that they tried to cash out on an exchange and got caught. Or they were initially found via other means and a search of their computers found the corresponding wallet.dat files.

Bitcoin is a public blockchain, there are various blockchain analytic firms such as Elliptic/Chainalysis that offer bitcoin tracing services.

Bitcoin is not private nor anonymous, the rise of blockchain surveillance is why privacy coins like Monero are gaining in popularity.

That being said, I'm sure it wasn't solely BTC transactions, these guys seemed to have very poor op-sec for performing such a big hack.
