Reddit announced today that it suffered a security breach in June that exposed some of its internal systems to the attackers, although what was accessed was not particularly sensitive. Notably the hack was accomplished by circumventing the two-factor authentication Reddit had in place via SMS interception — which should be a wake-up call to any who haven’t moved on from that method.

A post by Reddit CTO Chris Slowe (as KeyserSosa, naturally) explained that they discovered the hack on June 19, and estimated it to have taken place between June 14 and 18. The attack “compromised a few of our employees’ accounts with our cloud and source code hosting providers,” he wrote, gaining “read-only access to some systems that contained backup data, source code and other logs.”
