Cybercriminals have posted email addresses of more than 200 million Twitter users on a hacker forum. This became known from the co-founder of the Israeli cybersecurity monitoring company Hudson Rock, reports Reuters.

Cybersecurity researcher Alon Gal reported on LinkedIn that this hacking is “one of the most significant leaks he’s seen.” He stressed that this “will lead to a large number of hacking attacks, targeted phishing and doxing.”

Gal posted the report on the hack on social media back on December 24. There was no response from Twitter employees, as well as responses to inquiries about further violations. There is also no information about the location of the hackers.

Whether the investigation was carried out and how this problem was solved is unknown. The agency does not rule out that the hack could have happened as early as 2021, before Twitter became the property of Elon Musk.

Earlier, the private data of 5.4 million Twitter users was in the hands of cybercriminals.
