Zach Herbert reports Foundation Devices' analysis confirms the attacker used exposed LND .macaroon credentials to access funds, that only LND users are affected, and that no evidence was found that on-chain or hot wallets created in BTCPay Server were affected. He recommends updating to BTCPay Server 2.4.2. Held as a dated first-hand technical follow-up to his earlier report that the Foundation BTCPay lightning node had been drained. The findings are the poster's own and are not independently verified here.
