Mercado Bitcoin hack continued hours after exchange said attack was contained, report finds

Mercado Bitcoin suffered a hack that continued for hours after the exchange publicly said the attack was contained, according to a new report. The same attacker took roughly $391,000, mostly from wallets that Bitquery ties to BitMart, whose founder confirmed a Nov. 2 hack and suspects a link between the incidents. The finding matters because it suggests the exchange's initial all-clear came before the full scope of the breach was understood. Watch for further disclosures from Mercado Bitcoin and BitMart clarifying how the two incidents connect and whether additional funds were affected.
