Wireshark is a powerful Wi-Fi sniffing tool for intercepting communications between devices on a network. Today, well show you how to intercept images from a security camera on this episode of Cyber Weapons Lab.
Recommended network adapter: https://www.amazon.com/dp/B004Y6MIXS/?tag=whtnb-20
Most people watching security cameras rely on the usually insecure HTTP web server thats running on the camera in order to watch the security feed or change settings on the camera. This is commonly HTTP rather than HTTPS, and most people dont really bother to make the distinction or prefer to buy one thats secure because they dont understand the risk that it poses.
Now, on a network that has security, like a WPA network that has passwords, if you just have one person on the network, youre probably going to be okay if you have a pretty strong password and nobody can see the traffic thats going through it.
But the second somebody else gets your password or if its on an open or shared network, then you can really start to get in trouble because anybody can see these insecure HTTP requests over the network.
What this boils down to is we can actually see what the person is seeing on their screen, so if theyre watching the security camera or if they have a dedicated monitor set up to watch it somewhere in their business or home, then we can literally just download the packets as theyre transferring from one device to another, and then use Wireshark to export them and look at them on our screen.

When taking down a hacker, the first thing police usually do is plug in a mouse jiggler to the suspects computer to prevent it from locking. Using a Digispark microcontroller, we can create a device that, when plugged in, moves the mouse just enough to keep the screen from locking. While its most handy for that purpose, it could also be adjusted for a computer prank.

Payloads cant always be run easily. Often, you need to get around antivirus software and other defenses. The best way to do that is by hiding or obfuscating the payload. Today, in this episode of Cyber Weapons Lab, well look at a tool called Graffiti and use it to generate obfuscated payloads in languages such as Python, Perl, PHP, Batch, PowerShell, and Bash.

Being able to infiltrate communications between devices is extremely valuable to a hacker. On this episode of Cyber Weapons Lab, well show you how to create and manipulate packets with a Python tool called Scapy.
This is just a quick example of how a hacker could use Scapy to craft packets that allow them to stay under the radar even when theyre doing things on a network that theyre connected to. Because Scapy allows us to build packets from scratch, it means we can get as creative as we want. If we want to kick someone off the network while not being so obvious it was us, we can simply create fake packets that say that the router is the one kicking them off. We can also run a network scan by simply pretending to be the router sending out ARP requests getting everybody to reply and just sitting back and listening for those replies with Wireshark. Its really easy to use Scapy for a variety of different creative things, and the more you learn about TCP/IP, the more useful it will be for your hacking endeavors.
