Know Who Comes Into Your Home or Business to Prevent the Installation of Listening Devices

Ahh, physical access to your home or business; bad guys love that and you might never even realize that you opened the door and invited them in. Here at we have seen so many things over the years and while technology moves on creating more spy listening devices, we have to add them to the list instead of replacing old with the new. The field of technical counter surveillance measures just expands. Our experience in Technical Surveillance Countermeasures (TSCM) has shown us that access to your home or business opens up a wide array of spy surveillance options for bad guys. During TSCM sweeps we have uncovered many spy devices, including: A bug in a strip outlet, a clock, a radio or any other appliance [...]

Bug Sweep in Preparation for Top-Level Confidential Board Meetings

I just heard that the Teacher’s Union in a major metropolitan city has sent a notice of intent to strike to the school district. I won’t comment on that, but it did remind me of a case took on not too long ago when another company needed a Technical Surveillance Countermeasures (TSCM) specialist and specialized TSCM services. The Board of a large corporation was intending to meet to discuss a major change for the organization – there was even talk of a change of ownership. The rumors had workers and management nervous and twitchy. The Board knew that if any information they discussed leaked out, it could be disastrous for the current operations and, if they did change ownership, for the valuation of the company. [...]

Technical Surveillance Countermeasures Can Start Outside

You may think that tapping phone lines at your home means someone has to gain access inside the house. While it is possible to install phone tapping devices inside the rooms of your home or office, but you have to know that a bad guy doesn’t even have to get in your house to tap a phone line. A visit to the outside box or the riser could result in the bad guy getting access to your phone line and adding a phone tap device. That’s right. A visit to the box that’s on the outside of your home or office could provide the opportunity for your phone lines to be tampered with and allow your conversations to be overheard. It’s not just the box [...]

If You’re Asking, “Is My Office Bugged?” You Need to Talk to

If a bad guy has access to your environment, they can plant a bug. The most common way a bad guy gains access to a home or business is through the “service technician ruse.” It isn’t just in the movies, but in real life, too. He dresses as a service technician and says he is there to perform some service. While he is on the premises, he installs the bug. You might be surprised how easy it is for bad guys to do that. Security processes need to be established in every business, because every home and business is vulnerable without them. It’s important to only allow in workers that you have called to come provide a service, for you to see identification and to [...]

Listening Devices Might Not be the Only Threat to Confidential Business Matters

In one of my recent posts, I talked about how we did a Technical Surveillance Countermeasures (TSCM) sweep for spy listening devices in the offices of a business. We didn’t find any eavesdropping devices in their offices, but we did determine that one of the other businesses in the building was being bugged. When we conducted the sweep and found nothing, that was a good thing. The business owner knew someone had learned something that was being held confidentially and was concerned. So he took the first logical step in his mind to find out if there were listening devices installed in the areas of the office where sensitive discussions were taking place. Eliminating eavesdropping devices from the options, he could move forward. Automatically people [...]
