The concept of TMI – too much information – doesn’t 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?

A new survey-based research report from Tessian – with contributions from HackerOne – looks to raise awareness about this very issue. According to the document, 84% of roughly 4,000 surveyed professionals in the U.K. and U.S. said that they post on social media every week. About half share names and pictures of their children, 72% reference their birthdays and 36% volunteer information about their jobs.
