If you’re a user of social media scheduling app Buffer, there’s a good chance that your Saturday morning has been less than relaxing. There have been numerous reports circulating today purporting that the service has been hacked, and just a few moments ago the company officially confirmed those reports in a tweet.
“Hi all. So sorry, it looks like we’ve been compromised,” the terse statement reads. “Temporarily pausing all posts as we investigate. We’ll update ASAP.”

My brother uses it and his account was compromised.
