MySpace LLC and Tumblr, Inc. have been the targets of major data breaches.

The data breach for MySpace affects 360.2 million accounts created prior to June 11, 2013. The breach includes email addresses and passwords. Tests have shown that some of the passwords connected to the accounts are real and the social media company is already taking steps to protect its users.

The Tumblr data breach includes the email addresses of 65 million accounts with salted or hashed passwords from early 2013. This means those passwords have had extra digits added to them to make them harder to break, reports BBC News.

“If this indeed is a trend, where does it end,” Troy Hunt, who runs the Have I Been Pwned site, said to Computer Business Review. “What more is in store that we haven’t already seen?”
