Twitter hacked, 200 million user email addresses leaked, researcher says

It was not clear what action, if any, Twitter has taken to investigate or remediate the issue

Claims about the size and scope of the breach initially varied with early accounts in December saying 400 million email addresses and phone numbers were stolen.

Hackers stole the email addresses of more than 200 million Twitter users and posted them on an online hacking forum, a security researcher has said.

The breach “will unfortunately lead to a lot of hacking, targeted phishing and doxxing,” Alon Gal, co-founder of Israeli cybersecurity-monitoring firm Hudson Rock, wrote on LinkedIn.
