Most people who call about a bug sweep don't start with a device. They start with a feeling that someone knows too much. Here are the signs worth taking seriously, and what to do about them.
Warning signs that someone may be listening
- Private information has leaked. Someone knows details of a conversation, a business plan or a legal strategy that only a few people should know.
- Someone always knows where you are. A person turns up where you are, or comments on places you've been, without a clear explanation.
- Your home or office was entered. A break-in where nothing was taken, or furniture, ceiling tiles or wall plates slightly out of place.
- New or unfamiliar objects. A gift, charger, clock, smoke detector, USB device or power strip you don't remember buying.
- Someone had unsupervised access. A contractor, cleaner, ex-partner or former employee had time alone in your space.
- You're in a high-stakes situation. Divorce, custody, litigation, a business dispute or a major deal raise the motivation for someone to listen in.
Signs on your phone or computer
Battery drain, a hot phone, unfamiliar apps, or settings you didn't change can point to monitoring software, although they also have ordinary causes. If you suspect your phone, contact a professional from a different device, and don't announce your suspicions by text or email.
Signs in your car
A stranger near your car, scratches or loose panels near the wheel wells or bumpers, or a small box attached by magnets underneath can all indicate a GPS tracker. Read our guide to checking your car for a GPS tracker.
What to do if you suspect surveillance
- Don't confront anyone or search loudly. If a device is active, the person listening learns that you are on to them.
- Don't remove or destroy anything you find. It may be evidence. Take a photo and leave it in place.
- Use a different phone and location to ask for help.
- Speak with a professional. A TSCM bug sweep combines electronic and physical inspection to find devices, including ones that record without transmitting.
- Consider legal advice. Recording and tracking laws vary by state, and an attorney or law enforcement can advise on next steps.
Why consumer bug detectors often miss devices
Inexpensive detectors react to strong radio signals, so in a city they go off constantly, and they cannot detect devices that record to memory without transmitting. Professional sweeps use spectrum analysis, non-linear junction detection, thermal imaging and a hands-on search. Learn more in What is TSCM?
