Have you found out you are being listened to? It can be an advantage sometimes…
After having inspected the site, we inform the client that ordered our services about any security risks. We inform him about what we have found, what it can be caused by or for what purpose the suspicious signal or device can be installed or present in his site. Then it is on the client to decide if and how to respond to the fact or information. If he feels that his rights are being breached, it is on him whether he will report this fact to the bodies acting in criminal proceeding. He will decide whether he will protect himself according to certain recommendations or live with such activity or device.
Sometimes, it is beneficial to be one step ahead of the person listening to you. It means that if he does not know that you know, you can communicate in the area only information you want them to hear. You can secure yourself by communicating confidential information inly at a place that is safe or by misinforming the attacker with information that may confuse him. In general, if you take from an attacker one possibility, he can use another, even more serious tool that you may not be able to identify then.
