Turn two-factor authentication on for every account possible.The following steps will prevent hackers from getting their hands on truly sensitive information or being able to use the data they’ve stolen to get into your other accounts: While you cannot prevent data breaches yourself, you can reduce your vulnerability to data breaches in general. How to protect yourself from future breaches Two-factor authentication via SMS is insecure and you should switch to something safer, like a time-based one-time password app or a hardware security key. You could also receive malicious phone calls and text messages (smishing) trying to fool you into exposing sensitive information.Įven if your phone number doesn’t show up in the Have I Been Pwned database, if you’re using your phone number for a two-factor authentication (2FA), you should stop. If your phone number appears, you should unlink it from your Twitter account and any other accounts you use it for. You should also expect an uptick in the volume and quality of phishing emails you receive. If your email appears, you should remove it from your Twitter account and any other account you use it for. If neither appears, you likely have nothing to worry about. The first thing you can do is go to (new window) to see if your email address or phone number was exposed in the breach. How to recover from the Twitter data breach Hackers simply took the exposed email addresses and fed them into Twitter to add another data point to the ever-growing criminal databases. Hunt discovered that 98% of the emails in the Twitter database had previously been exposed (new window) in another data breach. It will also allow them to write much more convincing phishing attacks. Still, attackers can now link publicly known email addresses and phone numbers to Twitter accounts, potentially allowing them to identify and doxx Twitter users. There’s no evidence that hackers accessed users’ passwords or DMs. The company was informed in January 2022 that it had introduced a bug in an update in June 2021 that would allow anyone that entered a phone number or email address to see what the corresponding Twitter handle was (if one existed).Īt the time, Twitter claimed the breach exposed roughly 5.4 million Twitter handles (new window) and their corresponding emails and phone numbers. It seems likely that these account details were obtained by taking advantage of an API flaw that Twitter acknowledged in August 2022 (new window). Found 211,524,284 unique email addresses, looks to be pretty much what it’s been described as- Troy Hunt Janu(new window)
