Binance Hack: A Comprehensive Analysis and Timeline of Events63

On May 7, 2019, Binance, the world's largest cryptocurrency exchange by trading volume, was the victim of a sophisticated hack that resulted in the theft of 7,000 bitcoins (BTC) worth approximately $41 million at the time.

The attack was initially executed through a series of phishing emails sent to Binance users, which contained malicious links that directed the users to a fake Binance website. This website prompted users to enter their login credentials, which were then stolen by the hackers and used to gain access to their Binance accounts.

Once inside the Binance accounts, the hackers initiated a series of unauthorized withdrawals of BTC from the exchange's hot wallets. These wallets are used to facilitate trading and are often the target of hackers due to the large amounts of funds they hold. The stolen BTC was then transferred to multiple external wallets controlled by the hackers.

Binance detected the suspicious activity within a few hours and immediately suspended all withdrawals and deposits on the exchange. The company also initiated an investigation into the hack and contacted law enforcement agencies for assistance.

Binance CEO Changpeng Zhao (CZ) later confirmed that the hackers had gained access to user API keys and 2FA (two-factor authentication) codes, which allowed them to bypass Binance's security measures.

CZ also revealed that the hackers had exploited a vulnerability in Binance's SMS 2FA system, which allowed them to reset user passwords and disable 2FA without the users' knowledge.

Binance has since implemented several additional security measures to prevent similar attacks in the future, including:Requiring users to complete a 24-hour withdrawal verification process.
Implementing a new anti-phishing system to detect and block malicious emails.
Increasing the use of hardware security keys for 2FA.
Partnering with law enforcement agencies to investigate and prosecute the hackers.

Binance has also reimbursed all affected users for the stolen funds, totaling approximately $41 million.
