Nov 5 – Potential incriminating evidence found against the hackers who were responsible for the Japanese crypto exchange Zaif hack.
The hack was the result of a Security Breach on the Zaif Exchange in mid-September led to a loss of 6.7 billion yen (about $59 million) worth of crypto-assets which affected both the users and the exchange. Specifically the compromised funds consisted of 5,966 bitcoins (BTC), in addition to Bitcoin Cash (BCH) and MonaCoin (MONA).
Today’s statement outlines that since the stolen Monacoin began to be moved from Zaif Oct. 20, JDD has succeeded in identifying the source of 5 of the transactions in question and has provided information to the authorities concerning the characteristics of the transactions’ originator.
In order to track the stolen currency, JDD conducted a hackathon in late September together with local cybersecurity team TokyoWestern and security firm EL Plus, drawing upon infrastructure from multiple cloud services. The post states that:
“In the investigation of the stolen virtual currency, the remittance route was analyzed through a static analysis of the blockchain […] by deploying the virtual currency node at a large scale […] we verified whether we can obtain clues such as source IP address etc.”
