Tracking $1.63 million (approximately 2.19 billion won)... Different from the total damage amount from the payment serve

Approximately $1.63 million in Bitcoin (18.38 BTC) and Litecoin (3,405 LTC) has been traced across linked addresses following a hot wallet leak tied to an outdated version of the open-source BTCPay Server payment server, according to blockchain analytics firm Bitquery, which tracked transactions from October 30 to November 2. The tally covers 682 sweep transactions and includes two addresses published by BTCPay Server plus a separate Bitcoin wallet Bitquery linked with medium-to-high confidence based on transaction patterns, though not all activity from the two disclosed addresses has been confirmed as stolen funds. The traced amount differs from the total reported losses from the payment server hack, suggesting the full scope may be larger. The incident highlights custody and patch-management risks for merchants running self-hosted payment infrastructure. What to watch next: whether BTCPay Server or investigators confirm additional affected addresses and reconcile the traced $1.63 million against the hack's total losses.
