To succeed, we'll need to isolate traffic from the computer we're interested in with a Wireshark filter, capture a four-way WPA handshake, and then decrypt the data with the password we know.Д¬onditions must be favorable for this attack to have a chance of succeeding. Because Wireshark needs to observe a Wi-Fi handshake to decrypt subsequent traffic, simply knowing the password is not enough. One critical thing we'll need that isn't passive is a Wi-Fi handshake to see the traffic.

This means our attack will be mostly passive, leaving little opportunity for us to be detected. Instead, we can add the Wi-Fi keys we know to Wireshark, and decrypt the data we sniff without ever connecting to the network. If we know the password, we can always join the network ourselves, but this opens up a further risk of detection. We'll need to break the encryption of the network. To do this, though, there will be a few things we need to take care of first. Our goal will be to capture unencrypted HTTP traffic flowing to our target's computer as they view the security camera feed. To make this work, we'll need to use Wireshark to sniff Wi-Fi traffic between our target computer and the router. If a target has logged in and is viewing images from the security camera from an insecure web app live, it's relatively simple to intercept the web traffic and decode the intercepted packets into image files.

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.

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. 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. 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. 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. Because most businesses or homes with a camera have a monitor set up to view the camera, this can be a real concern for users with weak passwords or others sharing the network. If this is the case, anyone else who knows the Wi-Fi password can see exactly what the target is watching on the security camera. On security cameras, this problem is made much worse if the camera also hosts an insecure webpage where the owner can watch video play directly from the camera.

Even worse, some of these devices are designed to be exposed directly to the internet rather than just the internal network. As a result, it's common to see these devices appear on Nmap searches with insecure ports open. Convenience is often more important, so details like ensuring the administration page for a device is secure may seem like an afterthought to some developers. One thing internet-of-things devices typically have in common is a lack of focus on security. This means anyone with the network password can see traffic to and from the camera, allowing a hacker to intercept security camera footage if anyone is watching the camera's HTTP viewing page. It's common for IoT devices like Wi-Fi security cameras to host a website for controlling or configuring the camera that uses HTTP instead of the more secure HTTPS.
