That's what I keep my old Blackberry Z10 for. If I get something weird or want to go to dangerous places on internet (for research obviously) I use that thing. I'm pretty sure know one writes a 0-day for a 0.0% market share device.

Is your blackberry on your WiFi network? I’m guessing it hasn’t had a security patch in several years?

Be aware that an attacker could be automatically looking for exploitable devices just like z10 that and using that as a jump box into your network.

I use it mostly at home where it sits in the guest wifi(all connections between devices prohibited)

This is great, finally a use for old tech!

Right. 0-days did not not cross my mind. Until now.

Also, don't browse outside of your own VM...
