Description Vulnerabilities of modern phones, Features and Advantages The phone can be intentionally, or covertly, ‘off-hook’ during important conversations and negotiation Voice recording software can intentionally, or secretly, run on the smartphone Listening software can run in a ‘stealth’ mode Spyware can be installed on the smartphone without the owner's knowledge, allowing attackers to activate covert eavesdropping around the phone. Smartphone apps which have access to the phone's microphone can be used for eavesdropping in cases of them having been hacked (usually messengers or social network apps) There are known cases of transmission of such software by exploiting the vulnerabilities of some messengers Blocks the microphone of the phone with the help of non-filterable ultrasonic interference Efficiently prevents surround recording app from capturing conversations and sounds The frequency of interference has been optimally selected for the best performance and defeats all existing models of smartphones Made attractive with natural wood stand The phone stays online and available for incoming call No illegal radio jammin Can be powered by the external USB, or from the built-in rechargeable batter Has 2 sensors, increasing the battery’s resource: the device starts producing interference when a phone is inserted (IN USE sensor) and a conversation is present (ACTIVITY sensor Is compatible with all types of phone Accommodates from 1 to 4 phone Use in board rooms, R&D labs anywhere you need to secure conversations and meetings.
