Ports 80 & 81 Are Insecure
Ports 80 & 81 Are Insecure
When scanning devices with Wireshark, there are a few ports you're very likely to see open on devices like routers, security cameras, and other Wi-Fi enabled IoT devices. If you see a port 80, 81, 8080, or 8081, this very likely means there is an insecure HTTP website being hosted on that port. While you must know the password of a Wi-Fi network to scan for these ports, you can access them over the Wi-Fi network to inspect the web application they host.
While port 443 is used for secure HTTPS traffic, which is encrypted and doesn't present the same kind of interception risk, any port exposing an insecure HTTP port over the local network is an invitation for an attacker to snoop around for more information on the connected device. This can mean trying to log in, gathering information about the firmware the device is running or attacking it with a program like RouterSploit to attempt to break-in.
