Eavesdropping detection - protecting your privacy and business security

EXPERIENCE

For over 15 years, I have been working in the electronic countersurveillance industry, handling assignments of varying complexity.

I have gained experience inspecting everything from small offices in small companies to prestigious boardrooms for large companies and conference complexes.

During numerous projects, I have detected surveillance devices of varying degrees of sophistication – from simple designs, such as radio transmitters operating in the several hundred megahertz band, to complex systems that record voice and transmit signals in the 25 GHz band, including modern cameras measuring no more than a few millimeters.

As part of my services, I have conducted dozens of vehicle inspections, during which I have found both listening devices and GPS trackers.

EFFECTS OF ELECTRONIC SURVEILLANCE - WHY IT IS A PROBLEM THAT WE SHOULD BE CONCERNED ABOUT AND APPROPRIATE ACTION SHOULD BE TAKEN

Private and social consequences:

loss of privacy – eavesdropping and recording telephone conversations, video recordings from hidden cameras or GPS data in a vehicle constitute a violation of privacy (this may lead to the disclosure of personal secrets, which may result in, for example, blackmail and/or humiliation of the person being spied on by publishing the obtained materials)
destruction of interpersonal relationships - when private conversations are revealed, it can lead to conflicts in the family, problems at work, or loss of trust among friends
stress and a sense of threat – individuals who have learned that they were being surveilled often suffer from anxiety, depression, and a sense of uncertainty that can affect their mental health

Financial and legal consequences:

data theft and fraud – surveillance can lead to the theft of confidential information such as passwords, bank data, or credit card numbers, which can result in the loss of savings
Blackmail and extortion – criminals often use recorded conversations or video recordings for blackmail, demanding money for not disclosing compromising information.
losses for companies - a leak of confidential conversations or recordings can lead to enormous financial losses for companies, especially when it comes to trade secrets, know-how, or business negotiations (this can result in a decline in trust among contractors, investors, and a loss of competitive advantage)
Legal costs – individuals who have been victims of surveillance often choose to seek their rights in court, which entails legal costs and a lengthy legal process.

METHODS OF WIRETAPPING AND GATHERING INFORMATION AND WHO AND WHEN WILL BE EXPOSED TO WIRETAPPING

I. Surveillance from inside the room - vehicle - the eavesdropper must gain access to the above mentioned:

transmitters, audio recorders, GSM/Bluetooth/WiFi listening devices installed in RTV equipment, elements of alarm systems, CCTV cameras, access control systems, ventilation grilles, 230VAC sockets and computer networks, network splitters
cameras and voice recorders hidden in pens, USB drives, calculators, lamps, TV remotes or multimedia projectors
abandoned smartphones or other communication devices that, after installing the appropriate software, allow for environmental listening

II. Surveillance from outside the room - vehicle - the bug does not need access to the above-mentioned:

Seismic microphones - allow listening through the wall to conversations taking place in the neighboring room.
laser microphones - allow for eavesdropping on a conversation through a closed window even from several hundred meters away from the building
microwave microphones - allow for listening to a conversation from a distance of several hundred meters by demodulating a radio wave reflected from, for example, a metal bowl located in the room
optical systems - allow for eavesdropping in a given room by analyzing changes in the light emitted by, for example, a light bulb located in that room
Directional acoustic microphones - come in various types allowing for eavesdropping from distances of up to several hundred meters, depending on terrain and atmospheric conditions.

WHAT TO CONSIDER WHEN CHOOSING A SECURITY AND INFORMATION PROTECTION SPECIALIST

As can be seen from the above scheme, a high-class information security and protection specialist should be proficient in many fields and technologies that can be used in electronic surveillance.

Here, having a detective license, training, or even several years of experience in conducting inspections is not enough - having experience in engineering, constructing, programming, or servicing various types of electronic devices, including those used in electronic surveillance, is highly recommended.

All skills, experience, or knowledge should be confirmed by possessing the appropriate authorizations, licenses, certifications, completed projects - references.

WHY AM I THE OBVIOUS CHOICE ?

I. I have over 15 years of experience in the following areas:

detection and localization of listening devices, audio recorders, hidden cameras, wired surveillance systems, GPS in vehicles, and advanced radio systems operating in the range up to 25GHz
securing rooms against unauthorized recording of conversations, including blocking microphones in smartphones - remote eavesdropping, for example through Pegasus or interference by third parties on the phone will not be possible
consultation and security policy personalized for a specific user/company
designing electronic devices equipped with microphones with radio transmission, including GSM(GPRS) and GPS locators
designing devices that jam microphones
designing, servicing, and installing electronic security systems, including alarm systems, access control, and surveillance systems
computer and audio/video equipment service
installation and configuration of operating systems and software, including security systems

II. I have the necessary permits/certificates/licenses

III. Full discretion - by running a sole proprietorship and not having employees, I eliminated the possibilities of information leakage resulting from the above fact.
