5) Snooping or Sniffing
Hackers use sniffers to steal data, spy on network activity, and collect information on users. Usually hackers place sniffers in places that offer unsecured Wi-Fi connections, like we discussed earlier. Sniffers can be nearly impossible to detect and can be inserted almost anywhere. A simple way to combat this is to install Anti-Sniffing Software and or software that hides your browser history. Another way that professionals recommend is to encrypt everything you send or receive. If you receive a file in an email, even from a trusted source, it’s best to scan it with an anti-virus program before you open it. Some anti-virus programs will do this automatically, but don’t assume. Review your AV program, make sure it can do everything you need it to.
