A single hacker has managed to gain access to 5.4 million Twitter accounts. Reports suggest that Twitter suffered a security vulnerability which allowed user data to be extracted. User details are now for sale on a hacking forum, valued at $30,000. Further studies state that the vulnerability had become known to Twitter in January 2022, and has affected up to 1 billion Chinese residents. A spokesperson for Twitter said: “In July 2022, we learned through a press report that someone had potentially leveraged this and was offering to sell the information they had compiled. After reviewing a sample of the available data for sale, we confirmed that a bad actor had taken advantage of the issue before it was addressed.”
