Twitter has suffered a data breach after threat actors used a vulnerability to build a database of phone numbers and email addresses belonging to 5.4 million accounts, with the data now up for sale on a hacker forum for $30,000. 

Yesterday, a threat actor known as ‘devil’ said on a stolen data market that the database contains info about various accounts, including celebrities, companies, and random users.
