Blockstream notifies white hat hackers that vulnerability has been fixed, approximately 4,000 BTC pending return

Odaily News: Blockstream has notified white hat hackers that the vulnerability fix is complete and the approximately 4,000 BTC can be safely returned. The hacker who previously withdrew funds from the Liquid network expressed willingness to return them, but requested that the vulnerability be fixed first. Both parties have been negotiating publicly through Bitcoin OP_RETURN messages.

The hacker initially proposed returning "most" of the BTC, but later changed their stance, demanding that the vulnerability be fixed first: "Ensure every node has been patched, and once the fix is confirmed, we will securely return the funds." The hacker also sent encrypted vulnerability details to Blockstream. About two hours ago, Blockstream responded via a PGP-signed OP_RETURN message stating that nodes have been patched. Currently, 3,998.5 BTC remain under the hacker's control.
