can you recommend any (opensource or trusted) android apps to check who’s using your wifi? or any cmd prompt code to search on the desktop?
a small doubt: can anyone hack your computer through WiFi? If so, How to prevent that (or) How to take measures after you think you been hacked?
I forward all router logs to a syslog server which then parses and alerts me of “unknown Mac addresses” joining the network as soon as even one log shows up. If you have a syslog server and some way to index/parse those logs, that’s one way to do it
