"We believe that the hacker downloaded email addresses of users who contacted those three customers for support, as well as support email subject lines. We notified our affected customers immediately and are working with them to assist in their response," the company said in a blog post.

Twitter said in a tweet Thursday night that it sent emails to users believed to be affected, but also said that no passwords were believed to be involved. Earlier this month Twitter was hit with a security breach that affected about 250,000 users.

Tumblr also responded to the hack by sending some users an email warning them to take precautions

"This has potentially exposed records of subject lines and, in some cases, email addresses of messages sent to Tumblr Support.

The company said while this information may be "innocuous," users should still review any correspondence it had with Tumblr via email and beware of any emails claiming to be from Tumblr requesting a password.

"Tumblr will never ask you for your password by email. Emails are easy to fake, and you should be suspicious of unexpected emails you receive," the company said.

This is critical, as phishing emails are a common way cybercriminals trick people into sharing personal information.

Pinterest sent affected users a similar email, also cautioning them not to respond to suspicious email claiming to be from Pinterest, according to a Wired report.
