The emails could be employed to gain access to Twitter accounts not protected by two-factor authentication, according to the story.
“This database is going to be used by hackers, political hacktivists and of course governments to harm our privacy even further,” Alon Gal, co-founder of Israeli security firm Hudson Rock, told the newspaper. Mr. Gal had discovered the emails posted on an underground marketplace.
The breach may have come from a vulnerability, which Twitter disclosed in August, that inadvertently allowed site visitors to match email addresses with user accounts. Twitter didn’t respond to a request from the Post seeking comment.
