Linux Kali

I wrote a python script that allows you to easily ask what service runs on a specific port and vice-versa. Now, I am sure that such a program already exists on our lovely linux OS's, but... I didn't think of that before I started, and haven't found it yet. So if you haven't fo ...more

Well Welcome Back My Fellow Hackers. What is Slowhttptest? You may be asking. Slowhttptest is a Application Layer Denial of Service attack aka an attack on HTTP. You can read more about it here and also download it if you don't have Kali Linux. slowhttptest - Application Laye ...more

What you probably don't know is when you remove a file on your system, it is actually still saved, and not entirely removed. Let me tell you how to get rid of it completely. Overview: When you delete a file it is not removed entirely from your drive and can be recovered. No ...more

Design flaws in many routers can allow hackers to steal Wi-Fi credentials, even if WPA or WPA2 encryption is used with a strong password. While this tactic used to take up to 8 hours, the newer WPS Pixie-Dust attack can crack networks in seconds. To do this, a modern wireless ...more

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. This means anyone with the network password can see traffic to and from the camera, allowing a hacker to interce ...more

The internet is constantly under siege by bots searching for vulnerabilities to attack and exploit. While conventional wisdom is to prevent these attacks, there are ways to deliberately lure hackers into a trap in order to spy on them, study their behavior, and capture samples ...more

It only takes a few commands to manipulate a MacBook's secure HTTPS traffic and pluck login passwords out of the encrypted data. Let's take Facebook and Gmail hacking to the next level by intercepting Safari and Google Chrome web traffic in real time. Both Facebook and Gmail ...more

Wi-Fi devices are continually emitting "probe frames," calling out for nearby Wi-Fi networks to connect to. Beyond being a privacy risk, probe frames can also be used to track or take over the data connection of nearby devices. We'll explain how to see nearby devices emitting ...more

While Wi-Fi networks can be set up by smart IT people, that doesn't mean the users of the system are similarly tech-savvy. We'll demonstrate how an evil twin attack can steal Wi-Fi passwords by kicking a user off their trusted network while creating a nearly identical fake one ...more
