Today we test #OpulentVoice human-radio web interface against Web Content Accessibility Guidelines #wcag and write down anything that needs to be changed to make it more #accessible.

This phase will be driven from automated test suites from a variety of sources.

The next phase will be from people evaluating what we've done and letting us know where we need to do better.

Thank you to everyone helping us do ambitious work for #amateurradio !

Oh wow, #hamradio to the rescue

Remember that hurricane data that is being cut off by the US government? Guess who figured out how to get the data anyway?

Critical cryptographic flaw in Meshtastic Mesh Networking platform exposes private communications

Meshtastic, an open-source mesh networking solution for off-grid communication, has patched a critical vulnerability (CVE-2025-52464) that allowed attackers to decrypt private messages and hijack remote device administration due to identical cryptographic keys being shipped by manufacturers and poor randomness initialization. Users are urged to update to firmware version 2.6.11 or later and perform factory resets to eliminate potentially compromised keys.

**If you have Meshtastic devices, check the firmware. If it's 2.5.0 and above, it's very wise to update to firmware version 2.6.11 or later. Because attackers can read your private messages and take control of your devices. If possible, patch directly or reach out to your device manufacturer for a patch. After updating, perform a factory reset using "meshtastic --factory-reset-device" to clean up the old and potentially compromised encryption keys.**

#HamConBE might sound like a pure #amateurradio (#hamradio) conference but it actually more.

The conference also aims to bring together people from different communities of users of #radiotechnology in Belgium, ranging from #hackers and #makers (#meshtastic, #LoRa, wireless domotica, ...), scientists (#astronomy, #meteo, tracking birds, ...), #space, #cybersecurity, (#infosec) #education, and others.

Check out out #CfP at https://hamcon.be/
