How do I know if someone has me under surveillance?
There are two basic clues when you are the victim of a wiretap or electronic surveillance:
1. irregularities in phone or other electronics' performance, and
2. signs that other persons have information that you thought was private.
Your first step is to react calmly. Contacting the police or the phone company (both of whom may be involved in an administrative request) may result in the loss of important evidence through inexpert investigation.
Best approach: Call immediately and I will set you up with professional investigative sweep.
Irregularities on phone lines. Strange noises on your phone can be a sign of a wiretap. Popping, clicking, humming, static, and scratching are typical observations. Sometimes, your phone will make sounds seemingly on its own when it is on the hook. This can be a sign of an eavesdropping device that allows another person to listen to conversations in the room when the phone is not being used.
Irregularities on other electronic devices. Radios with sudden unexplained interference, at home or in your car, may be a symptom of surveillance devices operating on frequencies close to radio bands.
Hardware. Discovery of extra hardware in your phone or phone box or, in some cases, an actual recording machine has obvious implications. Do not remove or tamper with those devices. Call immediately for a professional and expert investigation.
Your secrets are out. Whether in the business or personal setting, you know what you consider to be private. But someone knows your secrets. Sometimes this results in loss of a competitive edge in business bids. It may be that someone knows too much: details about your day, your business, your personal contacts and communications. Sometimes it is blackmail. Unless there is a reasonable explanation, a protective sweep and appropriate countermeasure to catch the eavesdropper is your best course of action.
