Hey all,
For the past week there has been a continuous replay attack in The Netherlands.
Someone has been spoofing messages and sending them out again. This has caused some people to implement custom firmware on their repeaters to filter out 1 byte. But more worryingly, people are quitting the hobby and taking their repeaters offline.
Is it possible to build in protection against this? The public channel and some other hashtag channels like #nl cannot be used anymore since for every message you send, you get it back five or more times.
You can check the replay attack here: https://mc-spamdetector.nl/messages. It sometimes stops during the night but always starts up again.
Combined with the DOS attacks (PM flood spam) that take out the entire network for hours every day since the past 5 months, Meshcore is getting pretty unusable sadly.
