The blog is hosted on a PinePhone's GPS/WWAN/LTE modem, specifically the Quectel EG25-G modem.
The modem runs its own OS, Linux 3.18.44, separate from the PinePhone OS.
ADB (Android Debug Bridge) was used to access the modem, enabling root shell access.
A lightweight HTTP server, darkhttpd, was cross-compiled and deployed on the modem to host static blog files.
ADB port forwarding and iperf tests showed throughput of around 10Mb/s over the ADB connection.
Security concerns were raised about the modem's vulnerability to command injection and potential malware persistence.
