Yo everyone! I have questions about using cheap and generic mechanical keyboards. For example the Royal Kludge RK61 which has wired, Bluetooth and 2.4GHz connections. My host will be Linux machines. Do you see any security issues with using keyboards like that or were there any incidents of such devices being malicious?

Another concern might be the 2.4GHz USB that’s included. Assuming it’s not doing anything malicious is the connection encrypted or would you always instead use wired or Bluetooth? Thanks for any answers!
