Online reports, according to Bloomberg, Binance and Kraken have recently become targets of social engineering attacks similar to the incidents disclosed by Coinbase. However, neither exchange reported the leakage of customer information and successfully prevented the attack "due to internal protective measures." The attackers tried to use Telegram to lure customer service representatives to request "sensitive customer data such as account balances and home addresses." The report stated that "the AI security systems of the two exchanges recognized attack vectors and blocked phishing attempts." Previously, Coinbase disclosed in a filing with the U.S. Securities and Exchange Commission that cybercriminals "bribed overseas customer service representatives" in an attempt to obtain user data and account management records. The incident may result in up to US$400 million in remediation expenses and customer compensation. It is unclear whether the attackers who attacked Binance and Kraken were the same hackers who attacked Coinbase.
