Bitfinex Hack Overview

One of the largest crypto-related heists ever occurred in August 2016 when the Bitcoin exchange Bitfinex was hacked, resulting in the theft of over $7 billion in Bitcoin. The incident had a significant impact on the market.

After the attack, Elliptic was called in to trace the stolen funds. This article examines the 2016 Bitfinex hack, the subsequent investigations, and Elliptic’s involvement in tracking down the stolen funds.

What happened in the Bitfinex hack

In 2016, Bitfinex, a crypto exchange based in Hong Kong, was the target of a major cyber attack that resulted in the loss of approximately 120,000 Bitcoins. On August 2, 2016, hackers breached Bitfinex’s security measures and gained access to customers’ accounts and wallets. The attack caused significant financial damage to Bitfinex, making it one of the most devastating incidents in the crypto-exchange industry since 2011.

Due to security concerns, the specific events that took place are not fully known. However, it is suspected that the perpetrators exploited a flaw in the codes connecting the exchange to external services, enabling them to alter account balances and access funds. Additionally, it is believed that hackers took advantage of weaknesses in Bitfinex’s multi-signature wallet system, which is used to manage customer funds. There is speculation that the hackers obtained user login information prior to carrying out the attack on the exchange.

Thankfully, following the attack, the majority of customers were reimbursed thanks to various measures implemented by Bitfinex. These included bringing in new equity investors, obtaining settlements from previous investors who had lost funds, and receiving loans from executives at iFinex. However, this event should serve as a cautionary tale for other online exchanges, highlighting the potential security vulnerabilities in their systems.

How much money was stolen

Bitfinex, a cryptocurrency exchange based in Hong Kong, fell victim to a hack on August 2nd, 2016, resulting in approximately 120,000 bitcoins being stolen from customer accounts. The stolen bitcoins were valued at around $72 million at the time, making it one of the biggest hacks in history and causing significant turmoil in the cryptocurrency markets. The news of the theft led to a 20% drop in the price of Bitcoin, highlighting the importance of Bitfinex to traders at the time.

During its most successful period, hackers managed to steal almost 19,000 BTC from individual accounts and borrowed an additional 81,000 BTC in a margin trading scheme that ended poorly. The hackers meticulously planned their attack, taking advantage of vulnerabilities in Bitfinex’s multi-signature security system to gain unauthorized access to user wallets. They bypassed security measures by creating new accounts and transferring funds into them or by inputting incorrect seed addresses for existing accounts.

Bitfinex experienced a major hack in which approximately 120,000 bitcoin were stolen from user accounts, ranking it as one of the largest crypto thefts in history alongside the infamous MtGox hack of 2014. In an attempt to recover lost funds, Bitfinex issued IOU tokens to affected customers, however, these tokens were ultimately converted into BFX with no real monetary value.
