This is a developing story which we will update if new information becomes available
Unconfirmed reports tell us that the Cameroon regime led by President Paul Biya is using Cyber security tools like FinFisher’s FinSpy to target civilians who are having a critical position against the Francophone regime and / or support the secession of the Anglophone provinces.
As much as there is no proof yet to such allegations, it is publicly known neighbouring countries Gabon and Nigeria did in the past acquire such tools and currently have them available. .There is no technical reason as to why Gabon for instance could not share the toolkit with its neighbouring country
The functionality of the FinSpy suite includes the collection of address book information, calendar and phone call records; collection of files, screen captures, and photos, monitoring geolocation, surreptitious eavesdropping through enabling the victim’s microphone or placing hidden calls; as well as collecting communications and media, files from messenger apps like Line, WhatsApp, Viber, Telegram, Skype, Facebook, Messenger, Kakao, and WeChat
Gamma International / Lench IT, the company behind FinFisher says in a product brochure on FinSpy, published in 2014 the following: 
FinSpy has been proven successful in operations around the world since many years and valuable intelligence has been acquired about Target Individuals and Organizations.
When FinSpy is installed on a computer system or mobile phone it can beremotely controlled and accessed as soon as it is connected to the internet/network, no matter where in the world the Target System is based.
Usage Example 1: Intelligence AgencyFinSpy was installed on several computer systems inside Internet Café’s in critical areas in order to monitor them for suspicious activity, especially Skype communication to foreign individuals. Using the Webcam, pictures of the Targets were done while they were using the system.
Usage Example 2: Organized CrimeFinSpy was covertly deployed on the mobile phones of several members of an Organized Crime Group. Using the GPS trackingdata and silent calls, essential information could be gathered from every meeting that was done by this group.
FinSpy Mobile has been giving successful results to Government Agencies who gather information remotely from Target Mobile Phones.
When FinSpy Mobile is installed on a mobile phone it can be remotely controlled and monitored no matter where in the world the Target is located.
Usage Example 1: Intelligence AgencyFinSpy Mobile was deployed on BlackBerry mobile phones of several Targets to monitor all communications, including SMS/MMS, Email and BlackBerry Messenger.
Usage Example 2: Organized CrimeFinSpy Mobile was covertly deployed on the mobile phones of several members of an Organized Crime Group(OCG). Using the GPS tracking data and silent calls, essential information could be gathered from every meeting that was heldby this group.
Another pointer towards the Cameroon government at least being very aware of the possibilities of tracking user behaviour is the fact that they are already since at least 2013 in possession of BlueCoat devices on their public network, as discovered byCitizenLab
