There are dozens of commercial keyloggers and remote admin type apps out there. "Firewalls do not present a problem" to any of these, nor most of the other tools. I'm assuming here that they mean incoming firewalls, not restrictive bidirectional firewalls which block unknown outbound connections. The fact that this makes use of webcams and microphones is nothing new, Back Orifice did this a decade or so ago. None of the antispyware or antivirus vendors mark the commercial tools as malicious, because they assume (wrongly) that whoever put the tool there had a right to do so. I guess the only thing that is new here is that the company is distributing only to law enforcement. That might not even be new, since I'm sure the espionage community has some exclusively licensed tools at its disposal. If you want to get paranoid about something, be worried that your credit card info is in the hands of somebody in former Soviet countries or that some ransomware has taken over your PC. Trust me, the Swiss are not your biggest problem out there.
