I have long been researching the actual effectiveness of wifi “hacks” for private wifi networks. Long story short I need help to see if I am on a wild goose chase of something that isn’t worth protecting. The possible situation is a private wifi network where the owner of the network is the actual “hacker”. What product or service would they use that is readily availabel to packet sniff & monitor network traffic? Do they have the capability to log from the network the usernames, passwords, & most importantly 2FA codes? What about stealing a session cookie for a logged in social media account? A lot of people talking about “compromised data” but how far could they actually go?
