I was wondering yesterday on how this case would end:
https://www.coindesk.com/british-court-freezes-860000-in-bitcoin-linked-to-ransomware-payout
(detailed court order https://www.bailii.org/ew/cases/EWHC/Comm/2019/3556.html).

In the above case, a UK court has ordered Bitfinex to freeze an equivalent of 860k$ in BTC on an account, after the aid of Chainanalysis led to tracing the funds paid in a ransomware case, performed upon an insurance Company (and paid out in BTC by the insurer of the insurance company).

Along side freezing the assets, Bitfinex is being asked to dox the account owner, and that is where the uncertainty is as to what KYC data the ransomware perpetrators used: their own personal data, or yours (generic third party)? The outcome may be considered good or bad in this case, depending on the wit of the perpetrators.
