The main concept behind the law is that a trojan shall not be allowed to do everything, but only what has been specifically authorized by a judge’s signed warrant.

For instance:

* A Telephone Wiretapping Warrant is required to listen a Whatsapp call .

* A Remote Search and Seizure Warrant is required to acquire files on remote devices.

* An Internet Wiretapping Warrant is required to record web browsing sessions.

* The same kind of warrant that would be required for planting a physical audio surveillance bug is required to listen to the surrounding environment with the device’s microphone.
