In short
BTCPay Server supporters provided 10% of recovered funds, capped at 3 BTC.
Attackers stole Bitcoin utilizing credentials taken from susceptible LND servers.
Customers working affected software program ought to replace to model 2.4.2 instantly.
BTCPay Server supporters are providing 10% of any funds recovered, capped at 3 BTC presently price round $190,000, if all of the Bitcoin stolen in a latest exploit is returned.
In a put up on X on Monday, BTCPay mentioned the provide extends to anybody with info that might assist recuperate the funds, together with the attacker.
