Oversharing on Social Media
What Counts as Oversharing?
Oversharing is the habit of posting personal information on social media without considering how that information could be used by someone with bad intentions. It is not limited to obviously sensitive details like passwords or bank account numbers. Seemingly innocent posts about your daily life, holiday plans, family events, and routines can give away far more than you realise.
Holiday Posts and Travel Announcements
One of the most common forms of oversharing is announcing holidays before or during your trip. A post saying "Off to Spain for two weeks, can't wait!" tells anyone reading it that your home will be unoccupied for a fortnight. Photos posted in real time from a foreign location confirm that you are away. If your profile is public, or if your friends list includes people you do not know well, this information could reach someone who would exploit it. Consider sharing holiday photos after you return instead of while you are away.
Real-Time Check-Ins and Routine Posts
Posting "Just booked a cleaner for Monday at 2pm" tells the world when a stranger will be at your home. Similarly, regular check-ins at the gym every Tuesday at 7am, or school drop-off posts at the same time each morning, create a predictable pattern. Someone monitoring your posts could use this to know exactly when you are away from home and for how long. Vary what you share about your schedule and avoid broadcasting specific times and locations tied to your routine.
Personal Details That Aid Social Engineering
Social engineering is the practice of manipulating people into revealing confidential information or taking actions that compromise their security. Oversharing on social media provides social engineers with the raw material they need. Consider how much of the following you have posted publicly:
- Your pet's name: A common password and security question answer.
- Your mother's maiden name: One of the most widely used security questions for banking and official accounts.
- Your first car, school, or street name: All frequently used as security question answers. A "fun quiz" asking "What was your first car?" is often a data harvesting exercise.
- Your date of birth: Combined with your name and address, this is enough to attempt identity fraud in many contexts.
- Your children's full names and schools: This information could be used by someone attempting to impersonate a parent, carer, or school official.
Viral Quizzes and Challenges
Social media is full of posts that ask you to share personal details in a fun format: "Your stripper name is your first pet plus the street you grew up on" or "Share 10 facts about yourself." These posts are designed to extract exactly the kind of information used in security questions. Treat them with caution, regardless of how many of your friends have participated.
What to Do Instead
You do not need to stop using social media to stay safe. Instead, adopt a habit of pausing before you post and asking yourself a few questions:
- Could this post reveal when my home is empty?
- Does this post contain answers to common security questions?
- Am I sharing specific times, dates, or locations tied to my routine?
- Would I be comfortable if a complete stranger read this?
- Could this information be combined with other posts to build a detailed picture of my life?
If the answer to any of these is yes, consider editing the post or not sharing it at all.
