Bybit, a popular cryptocurrency exchange, has suffered a massive hack resulting in the loss of $1.4 billion in Ethereum.

The hack occurred on February 21, when a sophisticated attack on Bybit's wallet resulted in the theft of 401,346 Ethereum.

The hackers moved all the stolen Ethereum out of the dozens of wallets they originally split the proceeds between and converted most of the funds to Bitcoin.

Around 90% of the stolen Bybit funds have been converted to Bitcoin and are being held in approximately 4,400 addresses.

The remaining 10% of stolen funds have been lost to fees, freezes, or off-ramped.

The hackers used a decentralized protocol called THORSwap to swap assets across different blockchains, obscuring the origins of the stolen cryptocurrency.

Bybit's CEO, Ben Zhou, confirmed the hack and assured customers that other wallets had not been impacted.

The exchange had enough liquidity to honor withdrawals and survive the incident, but the hack has still caused significant financial losses.

Bybit reportedly had reserve assets of over $16 billion before the hack, but the stolen funds amount to a significant portion of its total assets.

The North Korean Lazarus Group has been linked to the hack, and Chainalysis reported that $2.2 billion worth of cryptocurrency was stolen through hacks last year.

Bybit has secured bridge loans to cover 80% of the stolen ETH, but the remaining 20% is still missing.

The hack has raised concerns about the security of cryptocurrency exchanges and the need for stronger measures to prevent such incidents in the future.

The investigation into the hack is ongoing, with Bybit working with blockchain monitoring firms and law enforcement agencies to track down the stolen funds.

Bybit's CEO, Ben Zhou, has acknowledged the hack and assured users that the exchange is investigating the breach. He stated that a transfer was made from the exchange's multisignature wallet to a warm wallet about an hour before the breach was identified, and the transaction appeared legitimate but contained malicious code.

The hackers altered the smart contract logic, allowing them to drain funds from the exchange. This sophisticated attack masked the signing interface, displaying the correct address while altering the underlying smart contract logic.

Cyvers Alerts shared their findings on abnormal activity linked to the exchange, detecting suspicious behavior involving the Bybit Official wallet. Several wallets were exhibiting highly suspicious patterns, and they actively reached out to the exchange to warn them.

The total affected assets are not specified in the article. However, Bybit's CEO, Ben Zhou, confirmed that 401,346 Ethereum (ETH) coins were stolen, worth around $1.4 billion at the time.

The hackers have moved nearly all of the stolen Ethereum out of the dozens of crypto wallets they originally split the proceeds between and have converted most of the funds to Bitcoin. This is the first phase of the money-laundering operation.

The market reaction to the hack was intense, with initial speculation causing Ethereum (ETH) to bounce back after an initial drop from $2,828 to $2,708 (a 4.2% decline).

This brief price rally was triggered by speculation that Bybit would need to buy back ETH on a 1:1 basis to compensate affected users.

However, Bybit's CEO Zhou later clarified that the exchange had secured a bridge loan covering 80% of the lost ETH and had no immediate plans to buy large amounts of ETH in the spot market.

The market swiftly shifted to a bearish sentiment amid concerns over selling pressure from the hacker and broader risk aversion among investors.

The hackers who stole $1.4 billion from Bybit moved nearly all of the robbed proceeds and converted them into Bitcoin, according to Tom Robinson, co-founder and chief scientist of crypto monitoring firm Elliptic. This is the first phase of the money-laundering operation.

The hackers used a decentralized protocol called THORSwap to swap assets across different blockchains, making it difficult to track the origin of the stolen cryptocurrency. This showed an "unprecedented level of operational efficiency" from the hackers, according to Ari Redbord, a former federal prosecutor and senior Treasury official.

The stolen funds were split into dozens of crypto wallets, but the hackers have now moved all the Ethereum out of these wallets and converted most of the funds to Bitcoin. Around 90% of the stolen Bybit funds have been tracked by Chainalysis, with the majority being held in approximately 4,400 addresses.

The hackers took steps to obscure the origins of the stolen cryptocurrency, making it harder to track and recover the funds. They used a technique called "musked transactions" to trick the exchange into signing a change in the code of the smart contract controlling a wallet holding Bybit's Ethereum.
