Recent reports suggesting that almost 33 million Twitter accounts were hacked, caused Twitter to take action. They locked many accounts and called password resets for security reasons.

According to Twitter, these hacks were not the result of any security breaches on their part, and speculated that it must be browsers, such as Chrome and Firefox that were breached using malware and saved passwords for more than 32 million Twitter accounts were obtained.

The hack affected millions of users, including famous personalities like Mark Zuckerberg, the CEO of Facebook; and Katy Perry, the famous singer with the most followers on the social network. The official NFL account was also breached. It is said that the security of many users was compromised due to their login credentials, which included easy and repetitive passwords. LeakedSource confirms that about 120,417 had the password “123456”. The fact that the CEO of Facebook had the password “dadada” further illustrates the case.

It was found that the hacker goes by the name of Tessa88, and was selling the account details of millions of Twitter users on the dark web.

To prevent any further harm to the owners of the affected Twitter accounts, the social network has started locking the accounts and e-mailing users explaining the situation. The exact number is not known, but the total number of accounts locked is said to be in the millions.

If your Twitter information was impacted by any of the recent issues – because of password disclosures from other companies or the leak on the “dark web” – then you have already received an email that your account password must be reset. Your account won’t be accessible until you do so, to ensure that unauthorized individuals don’t have access.

Twitter has taken many steps to increase the security level of their social network. From using HTTPS for its services, to encrypted passwords. During login, sign-in location and login history is taken into account to identify any suspicious activity when people try to sign-in to their accounts.
