Changing channels, scanning for access points, and even capturing packets all can be done from the command line. We'll use aliasing to set some simple commands for easy native packet capture on a macOS system.

Hack Like a Pro: How to Build Your Own Exploits, Part 3 (Fuzzing with Spike to Find Overflows)

Welcome back, my hacker novitiates! In the previous two posts in this series, we looked at the basics of buffer overflows. In this post, we will look at one technique for finding buffer overflows. We will try to send random, oversized, and invalid data at a variable to see whether we can make it crash or overflow. This process is known as fuzzing. It is often the first step to developing an exploit, as we need to find some variable that is susceptible to overflowing.

The Hacks of Mr. Robot: How to Use the Shodan API with Python to Automate Scans for Vulnerable Devices

Shodan calls itself "the search engine for internet-connected devices." With so many devices connected to the internet featuring varying levels of security, the special capabilities of this search engine mean it can provide a list of devices to test and attack. In this tutorial, we'll use Python to target specific software vulnerabilities and extract vulnerable target IP addresses from Shodan.

How To: Beat LFI Restrictions with Advanced Techniques

One of the most common web application vulnerabilities is LFI, which allows unauthorized access to sensitive files on the server. Such a common weakness is often safeguarded against, and low-hanging fruit can be defended quite easily. But there are always creative ways to get around these defenses, and we'll be looking at two methods to beat the system and successfully pull off LFI.

How To: Easily Detect CVEs with Nmap Scripts

Nmap is possibly the most widely used security scanner of its kind, in part because of its appearances in films such as The Matrix Reloaded and Live Free or Die Hard. Still, most of Nmap's best features are under-appreciated by hackers and pentesters, one of which will improve one's abilities to quickly identify exploits and vulnerabilities when scanning servers.

How To: Enable the New Native SSH Client on Windows 10

For years, PuTTy has reigned supreme as the way to establish a Secure Shell (SSH) connection.

Hacking Pranks: How to Flip Photos, Change Images & Inject Messages into Friends' Browsers on Your Wi-Fi Network

Networking is built largely on trust. Most devices do not verify that another device is what it identifies itself to be, so long as it functions as expected. In the case of a man-in-the-middle attack, we can abuse this trust by impersonating a wireless access point, allowing us to intercept and modify network data. This can be dangerous for private data, but also be fun for pranking your friends.
