Heads up: A hacker is reportedly currently trying to sell a dump of Yahoo accounts, up to 200 million of them, on The Real Deal Dark Web, according to Softpedia. This is particularly frightening given the sheer size of the number of accounts available for purchase, but also because this is the same person who allegedly dumped millions of MySpace passwords.
And we all know what happened in that case: Folks from the OurMine team started digging through that MySpace dump and others, including logins from LinkedIn and Tumblr, and started hacking into high-profile accounts. Mark Zuckerberg was hacked, as was Google CEO Sundar Pichai, just to name two affected individuals.
To keep yourself safe, we recommend changing your Yahoo password and making sure that any passwords and usernames that may have been similar to those you once used with Yahoo are safe as well. There’s a pretty good chance hackers are going to try to use your Yahoo logins to get into other accounts, too.
Yahoo told Softpedia it is investigating but has not yet posted a public response.
