Once a program has been compiled, it is not easy to get a peek at the source code or to manipulate its behavior. But there is one thing we can do, which is look at the hexadecimal values inside the binary files. We can also make changes to the data and compile it back to a binary file. This will sometimes reveal information about a file, or allow us to modify its behavior if we can manage to edit the right bit.

How to gain access to a MAC whitelist WiFi network
MAC address whitelisting sounds like a great way to prevent unauthorized access to your wireless network, but it does not work as well as you might think. The purpose of this guide is to demonstrate exactly how easy it is to spoof a whitelisted MAC address and gain access to a restricted network. In the steps below, you will see how to spoof a MAC address to gain access to MAC whitelisted network on Kali Linux.
How to crash Linux
There are a number of dangerous commands that can be executed to crash a Linux system. You may find a nefarious user executing these commands on a system you manage, or someone may send you a seemingly harmless command, hoping that you will run it and crash your computer.
Linux Fork Bomb
A Linux fork bomb is one of the oldest and most succinct ways to crash a Linux system. It is a type of denial of service attack that works by spawning more and more processes, until eventually all the resources on the system are tied up and it crashes.
Hardening Kali Linux
Although Kali Linux is notorious for being the distro of choice for penetration testers, hackers, and cyber security experts, it doesn’t mean that the operating system is not also vulnerable to exploits.
How to crack a wireless WEP key using AIR Crack
This article shortly describes simple steps on how to crack a wireless WEP key using aircrack-ng software. This can be done by sniffing a wireless network, capturing encrypted packets and running appropriate encryption cracking program in an attempt to decrypt captured data. WEP ( Wired Equivalent Privacy ) is quite easy to crack as it uses only one key to encrypt all traffic.
Change mac address with macchanger Linux command
A Media Access Control (MAC) address is a unique number that gets assigned to every network interface, including Ethernet and wireless. It’s used by many system programs and protocols in order to identify a network interface. One of the most common examples would be in the case of DHCP, where a router assigns an IP address to a network interface automatically. The router will know which device it has assigned an IP address to by referring to the MAC address.
Unlike an IP address, which is temporary and can be changed easily, MAC addresses are hardcoded into a network interface from the manufacturer. However, it’s still possible to change or “spoof” a MAC address temporarily. On Linux systems, one of the easiest ways to do this is with the macchanger command line program. There are both legitimate and shady reasons for why a Linux user may find the need to change a MAC address.
In this guide, we’ll show how to install the macchanger program on major Linux distros and then use the macchanger command to change the MAC address of a network interface either to a random value or some specific number. Follow the examples below to learn how.
In this tutorial you will learn:
- How to install macchanger on major Linux distros
- How to identify current MAC address and network interface
- How to change an interface’s MAC address
- How to change interface to a specific MAC address
Use JoomScan to scan Joomla for vulnerabilities on Kali
When installing a content management system for your website, it’s easy to get lazy and assume that it’s going to do all the work for you. A CMS like Joomla certainly does make things more convenient, and lets you publish a polished website very quickly, but that doesn’t mean you shouldn’t take some extra time to secure it.
If your website is running Joomla, you can use the JoomScan utility against your site to uncover vulnerabilities or just general information that can assist in an attack against your site. Once you’re aware of the the site’s weak spots, you can take the proper steps to secure it. JoomScan works similarly to WPScan, which is used for scanning WordPress sites for vulnerabilities.
In this guide, we’ll see how to use JoomScan on Kali Linux. JoomScan itself is not a tool that can be used maliciously while performing simple scans against a site, unless you consider the extra traffic itself to be malicious. But the information it reveals about a site can be leveraged by attackers to launch an attack. Therefore, make sure you have permission to scan a website when using this tool.
