In order to monitor encrypted communication, investigators will in future, according to the Senate draft and the Änderungen der Abgeordneten, not only be allowed to hack IT systems but also to secretly enter suspects’ apartments.
If remote installation of the spyware is technically not possible, paragraph 26 explicitly allows investigators to “secretly enter and search premises” in order to gain access to IT systems. In fact, Berlin is thus legalizing – as Mecklenburg-Western Pomerania did before – state intrusion into private apartments in order to physically install Trojans, for example via USB stick.
Usbguard, locked bios, and disallowing booting from USB. Good luck to them I guess.
Locked bios doesn’t mean anything if they have physical access to your PC.
They can reset the bios with a jumper, replace your bootloader, forensically image your hard drives and wait for you to boot and unlock your drives so they can grab the keys from memory.
A second trip could install a rootkit/malware because they know your encryption keys.
