Binance Kraken successfully defends against attack similar to Coinbase hack

While Coinbase was recently hit by a phishing attack, other cryptocurrency exchanges including Binance and Kraken were also targeted with similar attacks but successfully defended against them.
According to Bloomberg, the attack was an attempt to trick or bribe customer service employees to gain access to sensitive user information, and was reported by Coinbase on the 16th of last month.
The hacking was reported to the U.S. Securities and Exchange Commission (SEC) on Tuesday (local time). Coinbase is expected to incur security and customer costs of up to $400 million as a result of the hack.
The company also revealed that compensation costs may be incurred for customers, and that it would offer up to $20 million in compensation if the perpetrators are caught.
On the other hand, neither Binance nor Kraken have officially reported the damage, and no customer information has been leaked.
The hackers approached customer service representatives via Telegram and provided confidential information such as account balances and addresses.
However, both exchanges demonstrated the strength of the security of their internal systems by detecting and blocking such access in advance.
Coinbase insisted that customer passwords, private keys, and assets were not directly exposed to the hackers at the time of the incident.
However, it has been suggested that account management history and some user information may have been leaked to the outside.
