ZAIF Exchange Hack

Where did the almost 6k Bitcoin go? The other day Japanese based exchange ZAIF announced that it was hacked on the 14th for around 5960 Bitcoin along with some bitcoin cash and MonaCoin (approx. $60mill worth at the time). After being reported the Coinfirm team began using the Coinfirm VIS solution to trace the flow of the stolen funds and flagged the related address in the Coinfirm AML Platform accordingly.

Some funds went to the largest exchange in the world and some of them got mixed using HelixMixer however, 2455 BTC is still sitting on the address 3HfQmx4QBBVB6699mhSpdbVnYq19pxPWsu which received the funds from the original hack address.

Below you can see through the Coinfirm VIS solution where the funds are moving or moved

According to the the AML model, once reported the data was analyzed for its correctness and then once determined to be valid was implemented in the Coinfirm AML Platform with the appropriate flags and identifiers. As you can see in the reports below the related addresses now have been identified as being hack related and have an elevated risk rating corresponding with the new flags and risk indicators.
