Twitter has been hacked, 200 million user e-mail addresses are out, the researcher says.

He called it “one of the most important leaks I've seen. ”Twitter has not commented on the report, which Gal originally posted in social media on December 24th, nor did he answer questions about violations since that date. It was not clear what action he took if he received Twitter to investigate or correct the case.

Reuters could not independently verify that the data at the forum was authentic and came from Twitter. Images of the hackers' forum screens, where data appeared Wednesday, have circulated online.

Troy Hunt, the creator of the page for reporting violations, <x0Have I Been Pwned” saw the resulting data and said on Twitter that it looked “roughly as described”.

There was no record of the identity or location of hacker or hacker after the violation. It may have been that in 2021, before Elon Musk bought the company.

The claims on the size and extent of the violation initially ranged from early accounts in December, saying 400 million email addresses and phone numbers had been stolen.

A major break on Twitter may interest regulators on both sides of the Atlantic.

The Commission for the Protection of Data in Ireland, where Twitter has its European headquarters, and the US Federal Trade Commission has monitored the company owned by Elon Musk for compliance with European data protection regulations and a US consent order, respectively.
