I have only seen intelligence visiting my home when I left an
offline computer around with HDD.
If you feel safe answering: what country was this in? Your name and
time zone suggest Germany/Austria/Switzerland, which I wouldn't have
thought of as the kind of places that do this.
With the amendment of the StPO 2017, the German Bundestag created a
legal basis for the widespread use of these so-called Statetrojans[¹]
More states have laws that let they spy citizen with trojans. This
cause our device/software to be less secure and the same backdoor can
be used also by others. Also when data is collected is also accessible
by people who work directly/indirectly and some of these can use that
data (sell/send to others/read for himself/...)
Yes, I´d believe it to be a problem when the state buys zero days
exploits which are then kept secret so that they can continue to be
exploited. In the worst case people are paid for moving malicious bugs
in and by selling them later on. The state should act responsible and
contend to improve the security of our systems instead of undermining
them. If it is true what I have heard then intelligence services in
Germany are still using typewriters.
