Zaif

Zaif is a cryptocurrency exchange that handles currencies including Bitcoin, Bitcoin Cash and Monacoin. As of September 2018, it was ranked as the 35th largest cryptocurrency exchange by turnover,[1] and was one of sixteen cryptocurrency exchanges licensed and regulated by the Japanese Financial Services Agency (FSA).[2]

On September 14, 2018, the exchange was hacked and the equivalent of $60 million in cryptocurrency was stolen. The hackers reportedly gained access to "hot wallets" through which the exchange held funds for immediate transactions. Tech Bureau said that it did not notice the breach until Monday, September 17, and that the breach was then promptly reported to police and the FSA.[3] The hack resulted in a suspension of withdrawals and deposits, and a bailout agreement with Fisco, a Japanese company that injected 5 billion yen in financial support to Tech Bureau.[1][2]

According to analysis completed by Bitfury’s Crystal Blockchain Analytics engineering team, 30% of the stolen Bitcoins are still located at addresses related to the hacker.  Another 24% were sent to Binance for exchange/withdrawal. The remaining 46% were split into small amounts and sent to various addresses.[4][5]
