BitFinex Was Previously Hacked

While the F Society ransomware group’s claims are unverified, BiFinex had previously fallen victim to a major hacking incident in the past.

In the earlier 2016 incident, about 119,754 in bitcoin was stolen from the Bitfinex platform after a hacker breached its systems and initiated about 2,000 unauthorized transactions. The stolen bitcoin was sent to a man, who along with his wife, attempted to launder the money across digital accounts.

Law enforcement managed to track the couple after 6 years, and managed to recover more than 94,000 bitcoin that had been stolen from Bitfinex. The total value of the recovered bitcoin was stated at over $3.6 billion at the time of arrest, making it the single largest recovery in the history of the US Department of Justice.

However, the perpetrator of the hack is still unknown but is known to have used a data destruction tool to cover their trail. A former FBI agent was quoted as stating that Bitfinex’s earlier security lapse was likely due to its desire to accelerate transactions and thereby raise profits.
