Hackers attack Twitter, Pinterest and Tumblr

If in doubt, change your password. Customer support tool Zendesk had been hacked earlier in February, and that affected Zendesk’s clients Twitter, Pinterest and Tumblr.

“We believe that the hacker downloaded email addresses of users who contacted those three customers for support, as well as support email subject lines,” explained Zendesk on their blog.

Pinterest responded by urging users to take measures to protect their accounts by using strong passwords and not sharing their passwords.

Tumblr warned its customers to review any e-mails they had shared with Zendesk to make sure no account information could be used by the hackers.
