Finally got the pinephone GTK rust starter app to build on device & pinebook. Had to use Manjaro beta phosh, it appeared like it might build on pmOS edge but definitely wouldn’t on stable. Pretty excited to write a mobile app in rust, glade opened the app UI fine and it builds the same on both devices which will make testing & developing simpler.

This is the pinephone OS I want to become stable, the UX Lomiri is so clean and beautiful to use. It’s in an early alpha state, crashes and has many bugs but if Manjaro gets this UX to stable it will reign king of the Linux on mobile. Ubuntu Touch uses the same UX but comes with too much bloat for my tastes. Great game boy emulator tho.

If you don’t read the code, how will you find the backdoors? As for using libpurple to handle SMS passed over a D-Bus interface... I have concerns. Going up against the pinephone web renderer and jscript engines seems difficult, the radio interface layer is best bet for a good RCE, either Linux Bluetooth / WiFi or some telephony stack bug in handling SMS/MMS. The hardware decisions around the baseband make it more difficult to reach OS from the RIL, but libpurple? It’s more holy than the Pope.

Exploitation of human behavior always gives better results than a single bug. I wrote this example for macOS in Swift. It's a great LPE attack, by presenting every 15 minutes a UIKit dialog that mimics precisely Apple notices, users will just enter the local admin (or iCloud) password. On every run, this stores clipboard and passwords input from a launchd daemon, once the user gives the right password and it authenticates to root - it clears out the persistence and transmits the logs back to me.

Power only microUSB, it's always nice to find a microcontroller that is sitting away from lifes biohazards.

Motorola T800, 462Mhz-467Mhz FRS/GMRS license-free 400mW 2-Way radio with BTLE enabled modem. JTAG port identification and disassembly process.

BladeRF xa4, running with a LNA/power amp. Setup on the 2m/70cm bands to assess local radio data. This SDR is the best choice on the market for pros, the FPGA is large enough for most common DSP and standalone demodulators you would need. The ADC gives a nice 12bit resolution and 2x2 MIMO for multi-path propagation. Thanks to the pinebook having a USB3 port, it works perfectly with gnuradio giving you two independent tx/rx chains at 60Mhz wide. I’ve used most SDR’s, it performs as good as USRP.

Standing wave from a mismatched antenna sending voltage back towards the ADC on a SDR, produced this weird waterfall glitch from the returned energy. Looks very pretty but probably harmful to the radio. :))

I love that my work ended up in the github Arctic Code Vault. I just noticed that this had been added today to our company profile.
