Most gun thefts and doxxing incidents do not start with a sophisticated attack. They start with information the owner gave away: a photo, a shipping box, a reused password. Operational security, or OPSEC, is the habit of not handing that information out.
None of this requires expensive gear. It requires paying attention.
1. Strip location data from your photos
Phone photos often carry GPS coordinates in their metadata. Post a picture of a new rifle on your kitchen table and you may be posting your address along with it. Turn off location tagging in your camera settings, and use a metadata remover before sharing photos publicly. Many social platforms strip metadata, but not all, and not when you send the original file.
2. Watch the background
Even without metadata, a photo can show your house number, street signs, the view from a window, or mail on the counter. Check the edges of every frame before you post.
3. Never post serial numbers, receipts or paperwork
Serial numbers, receipts, transfer paperwork and approval letters link a specific firearm to you. Crop or blur them, or do not post them at all.
4. Break down the boxes
A gun safe box or a case of ammunition at the curb tells everyone on the street what is inside the house. Break down boxes, turn them inside out, or take them to recycling yourself.
5. Skip the bumper stickers
Brand decals and gun-rights stickers on a vehicle can mark it as a likely place to find a firearm. That makes your car, and possibly your driveway, a target.
6. Post range days after you leave
Real-time posts tell people where you are and that you are not home. Share range photos and trip updates after the fact.
7. Lock down your accounts
Retailers, forums and online services get breached. When they do, attackers try the same email and password everywhere else.
- Use a password manager and a unique password for every site.
- Turn on two-factor authentication, especially for your email, retailer accounts and any ATF eForms account.
- Consider a separate email address for firearms purchases and forums.
8. Treat your home network like a safe
Security cameras, smart locks and safe monitors are only as secure as the network they sit on. Change default passwords, keep firmware updated, and if your router supports it, put cameras and smart devices on a separate network from your computers and phones.
The bottom line
Responsible ownership does not end with secure storage. What you share, and where you share it, is part of keeping your firearms, and your family, safe.
