Cybersecurity experts at Japan Digital Design, a subsidiary of Mitsubishi UFJ Financial Group, say they've found possibly revealing information on the bad actors behind the $60 million hack of Japanese crypto exchange Zaif.

Once some of the stolen funds, in the monacoin cryptocurrency, started being moved late last month, Japan Digital Design said it was able to identify the "Source" of the attackers.
The team added that has shared this information with the authorities, saying: "Since the Monacoin began moving from October 20, we estimated the source of 5 transactions in question and provided information to the authorities concerning the characteristics of the transaction originator."
"In the investigation of the leaked virtual currency, remittance route has been analyzed through static analysis of the block chain, but with this effort, by deploying the virtual currency node on a large scale after the outflow of the virtual currency, we verified whether we can obtain clues such as source IP address etc. We also got useful data to grasp the accuracy of the information and the cost of tracking."
