On August 2nd the Hong Kong-based Bitcoin exchange Bitfinex was compromised for roughly $70 million worth of Bitcoin. According to sources, the attacker managed to drain the exchange through its multi-signature security — gaining 120,000 BTC from the breach. Now the exchange is trying to reach out to the responsible party in an attempt to get its customers’ Bitcoin returned.
The Bitfinex compromise shook the entire cryptocurrency community last summer. When the attack happened Bitcoin’s fiat value plummeted to $480 per BTC. Since then, its price has bounced back and Bitfinex is again fully operational.
As time passed, the company has provided additional information on reimbursing its customer base via its own issued BFX token.
However there has been little information on how the exchange is working with authorities, or the investigation progress. We do know the FBI is aware of the attack though, as a Massachusetts resident has filed a complaint about the loss of $1.3 million USD in Bitcoin.
