Total Defense Security Tip of the Day

The stranger danger alert: why you should question that new follower
We love social media because it lets us connect with practically anyone, anywhere. That’s an amazing power, but it’s also the wild west of personal safety. On the internet, people can easily hide behind fake profiles, completely change their identity, and disguise their real intentions.
It’s time to activate your online "Stranger Danger" senses. You need to be incredibly careful about who you allow into your digital life and how much information you share with a person you've never actually met.
Who Are You Really Talking To?
Think about that new friend request or DM you just got. They might seem charming, interesting, or share all your same hobbies. But on social media, that profile is just a carefully crafted story.
People use fake identities for all kinds of reasons—some are harmless, but many are not. Scammers, harassers, and even predators actively hunt for vulnerable people online. This is called catfishing, and it is shockingly common. They build trust with you by pretending to be someone they're not, often with the goal of financial fraud, emotional manipulation, or even physical harm.
You must remember this core rule: Anyone you meet solely online is a stranger. Period.
Control Your Digital Circle
The best defense is often a good offense, and that means taking control of your platform settings right now. Don't leave your profile open for just anyone to contact you.
Go into your social media privacy settings and restrict who can send you friend requests or direct messages. Limit it to people who are already friends of friends, or better yet, only those you know in real life. This small step significantly shrinks the pool of potential bad actors who can reach out to you.
What to Do If You Talk to Strangers
Sometimes, engaging with strangers online is unavoidable, whether for work, a hobby community, or a public interest group. When you do, practice extreme caution:
- Be a Lockbox with Personal Details: Never, ever share personal identifying information. This includes your full address, your phone number, where you work, or specific details about your daily routine. Every piece of data you give them is a tool they can use against you.
- Trust Your Gut: If a conversation makes you feel weird, uncomfortable, or pressured, end it immediately. Real friends don't demand secrecy, ask for large amounts of money, or try to rush a relationship. If something feels too good to be true, it almost certainly is.
- Never Meet Alone: This is the most crucial warning. Never agree to meet an online-only contact in person without taking serious precautions. If you decide to go through with it, meet in a public, well-lit place with other people around, and bring a trusted friend with you. Always tell someone else where you are going and who you are meeting.
Your digital life is only as safe as you make it. Take an active role in screening your connections, protect your personal information, and remember that when you see a stranger online, a screen is all that separates you. Stay safe out there!
