Just now, Coinbase suffered a targeted social engineering attack. What happened? Criminals obtained less than 1% of Coinbase's MAU personal data through social engineering methods such as bribery and internal agent infiltration. But there is no password, private key, or fund theft. And the attacker made a ransom request of $20 million to Coinbase. Coinbase's MAU is approximately 8-10 million, with 1% being 80000 to 100000 people. The specific personal data leaked has not been disclosed. However, for the 1% of people whose information has been leaked, they may receive phishing emails from hackers next, and the simulation degree will be very high. What are Coinbase's response measures? Coinbase has explicitly stated that it will not pay the $20 million ransom demanded by criminals. Simultaneously announced the establishment of a $20 million reward fund to provide information for locating relevant criminals. Coinbase promises to compensate affected users and emphasizes that it will update machine learning models or other technological means to detect and prevent similar attacks.
