BTTCPay Server restricted access to the Lightning Network and funds were stolen due to loopholes

After confirming that the attackers had used critical loopholes to steal lightning network vouchers and transfer funds, BTTCPay Server temporarily restricted public remote access to the flash network nodes operating on LND. This loophole affects all pre-versions of BTTCPay Server, including 2.4.2 pre-publication. BTTCPay has confirmed that the users were affected and that the funds were stolen, but has not disclosed the total loss or the number of operators affected. The project promises to issue more detailed follow-up reports in the coming days。
