The phone numbers of millions of people on Twitter were put up for sale online.
A blow to Twitter, which experienced turbulent days with the purchase of Elon Musk, came from hackers. The data of millions of users, both active and disabled, is sold on the internet.
Hackers stealing the phone numbers and email addresses of 5.4 million users are selling the data on hacker forums.
However, it is stated that about 1.2 million accounts suspended on Twitter were also stolen.
According to security experts, hackers seized data through a flaw in the Twitter API codes.
Sources say that the vulnerability could have been used for a longer period of time and that 17 million users were affected. However, the remaining leaks are not yet on sale.
Twitter users should be careful
Experts warn that attackers will try to deceive users by phishing.
Leaked phone numbers are often used to defraud people. For this reason, you need to be careful against calls and SMS from numbers you do not know in the upcoming period.
