Twitter reported that by analyzing the appearance of suspicious traffic that led to the leakage of customer data, it eliminated the detected vulnerability on November 16. However, this information led to the fact that on Monday the company's shares lost almost 7%, which was the maximum decline in more than 2 months. This was reported by finversia.ru. Twitter experts said that a significant stream of suspicious traffic was sent to the customer support site from IP addresses in China and Saudi Arabia. The Chinese authorities, who are trying to combat cyber attacks, have declared that they are not involved in hacking.
