Research on brain tapping and variants are usually conducted in secrecy by different military agencies and almost certainly by large corporates. The former includes the CIA, FBI, certain units of the Indian military and many others. In the US, a few judicial cases relating to such activities have actually gone against the state. Such research and the equipments developed are never reported to the public and academic bodies. Exceptions include relatively lighter CIA games like the MK-ULTRA (1952-62 : officially) that was disclosed in 1975. Apart from these the few disclosures that have happened have been subjected to much counter propaganda and counter actions.
With the severe advancement in the management of vague and imprecise information since the seventies, the increase in computing power, AI, neurobiology and advances in 'brain tapping' technologies, we have a lot of reasons to feel all the more insecure. This insecurity has more to do with the essential nature of closed source software and hardware than anything else. It is too difficult even for skilled reverse engineers to pronounce completely on what they seem to see.
Already we have good many applications available. It is so EASY to misuse them. Some links are:

Who knows what the CIA and other agencies have hidden in the M$Windows to start with?
When a group of wild buffaloes is charging at you, then you must not wait for the stampede!
These are important reasons for a total ban on closed source software and hardware.
