Amazing how fast quadcopters and the associated technologies are developing.
My router got hacked earlier this evening TL-WR841N. The tell tale sign are your DNS settings on the router. If your DNS settings are not what they are supposed to be (google 18.104.22.168 22.214.171.124 or opendns 126.96.36.199 188.8.131.52 or your ISPs) then I suggest you unplug your router and either buy a new one or re-flash with openwrt or ddwrt (If your router isn’t effected do not upgrade your firmware (unless your 100% sure the update wont make your router vulnerable.) that’s how my router got pwn’d)
