So to hopefully make it more clear, I wrote a CLI tool which can recover the decryption parameters for DM conversations. It basically does everything but the final AES-CCM decryption. Turns out there's something funky with the meshtastic AES-CCM implementation and I can't seem to fully decrypt using an openssl based library. This does not mean DMs are any safer, just that I haven't taken the time to crosscompile the MT/arduino AES routines to x86 yet. https://github.com/datapartyjs/meshmarauder/blob/main/bin/mitm-dm #meshtastic

    Over the weekend @meph@social.treehouse.systems added some mind blowing new features to lorapipe. - APRS over LoRa - Ethernet over LoRa https://social.treehouse.systems/@meph/115365077448221139 #hamraadio #radio #lora #meshcore #meshtastic #lorapipe #aprs #ax25 #kiss #tnc #packetradio #networking #cybersecurity #offgrid

  • @nullagent@partyon.xyz this is excellent work. Thank you. A LOT of my friends have been talking MT and while I knew there were some flaws and exploits, this is a great summary of the current problems! Keep on killing it out there! 🏴🦝🏳️‍⚧️

    @nullagent@partyon.xyz @nullagent@partyon.xyz in my local hacker/activist community, we are working really hard to get people to ditch Meshtastic in favor of Reticulum, including building out our own local mesh network with it. To anyone that has been sold on the promises of Meshtastic, I'd definitely recommend you do the same! The security/encryption of Reticulum is far superior, and the feature set is far more complete (it can be used for text, voice calls, hosting websites, TCP/IP tunneling, really anything), it can interoperate on way more radio protocols than just LoRa (including many non-radio protocols), and the development team seems far more committed to FOSS and anti-corporate ideals. It also doesnt use flood-routing, unlike Meshtastic, so the network gets significantly more efficient as nodes are added, rather than getting bogged down the way Meshtastic does. Thank you for putting this info out there, it's very refreshing when so many out there are parroting Meshtastic's marketing materials on its security while simultaneously advocating its usage in high-risk environments like protests. #reticulum #meshtastic #lora #mesh #privacy #radio
