The concept of TMI â too much information â doesnât just apply to socially awkward dinner conversations with your surprisingly loose-lipped blind date. Employees and executives are often oversharing personal details on social media and even in automated out-of-office (OOO) email messages. And under the wrong circumstances, an attacker could use some of these shared details to gain access into company networks. Of course, OOO instructions serve an important business communications function, and a strong strong social media profile is a great way to network with your peers and brand yourself. So the question becomes: Where do you draw the line? What constitutes TMI?
