Phishing Attack Grabs Thousands of Tumblr Logins

Hackers have grabbed thousands of Tumblr users' logins in a massive phishing attack. The typically simple but effective assault on the microblogging site presented users with a screen asking them to "revalidate their credentials" in order to view adult content, reports GFILabs. Compromised accounts were used to spread the scam.

It's not clear what the hackers plan to do with all those logins, but there is the "very real possibility that the Tumblr accounts are simply a way to test if those users are logging into other services with the same credentials," GFI notes. (More Tumblr stories.)
