How To: Hack WPA WiFi Passwords by Cracking the WPS PIN
A flaw in WPS, or WiFi Protected Setup, known about for over a year by TNS, was finally exploited with proof of concept code. Both TNS, the discoverers of the exploit and Stefan at .braindump have created their respective "reaver" and "wpscrack" programs to exploit the WPS vulnerability. From this exploit, the WPA password can be recovered almost instantly in plain-text once the attack on the access point WPS is initiated, which normally takes 2-10 hours (depending on which program you use).

How To: Hunt Down Social Media Accounts by Usernames with Sherlock
When researching a person using open source intelligence, the goal is to find clues that tie information about a target into a bigger picture. Screen names are perfect for this because they are unique and link data together, as people often reuse them in accounts across the internet. With Sherlock, we can instantly hunt down social media accounts created with a unique screen name on many online platforms simultaneously.
How To: Scan for Vulnerabilities on Any Website Using Nikto
Before attacking any website, a hacker or penetration tester will first compile a list of target surfaces. After they've used some good recon and found the right places to point their scope at, they'll use a web server scanning tool such as Nikto for hunting down vulnerabilities that could be potential attack vectors.
How To: Get an Internet Connection in the Middle of Nowhere to Hack Remotely

Exploiting the poor, neglected computer inside these routers has become so popular and easy that automated tools have been created to make the process a breeze.
How To: Manually Exploit EternalBlue on Windows Server Using MS17-010 Python Exploit
EternalBlue was a devastating exploit that targeted Microsoft's implementation of the SMB protocol. Metasploit contains a useful module that will automatically exploit a target, as long as it's vulnerable. But what if we wanted to exploit this vulnerability without Metasploit holding our hand? It can be done using a Python file to exploit EternalBlue manually.
How To: Use Ettercap to Intercept Passwords with ARP Spoofing
ARP spoofing is an attack against an Ethernet or Wi-Fi network to get between the router and the target user. In an ARP-spoofing attack, messages meant for the target are sent to the attacker instead, allowing the attacker to spy on, deny service to, or man-in-the-middle a target. One of the most popular tools for performing this attack is Ettercap, which comes preinstalled on Kali Linux.
How To: Crack Password-Protected Microsoft Office Files, Including Word Docs & Excel Spreadsheets
Microsoft Office files can be password-protected in order to prevent tampering and ensure data integrity. But password-protected documents from earlier versions of Office are susceptible to having their hashes extracted with a simple program called office2john. Those extracted hashes can then be cracked using John the Ripper and Hashcat.
How To: Use Kismet to Watch Wi-Fi User Activity Through Walls
Your home has walls for privacy, but Wi-Fi signals passing through them and can be detected up to a mile away with a directional Wi-Fi antenna and a direct line of sight. An amazing amount of information can be learned from this data, including when residents come and go, the manufacturer of all nearby wireless devices, and what on the network is in use at any given time.
How To: Brute-Force FTP Credentials & Get Server Access
Hackers often find fascinating files in the most ordinary of places, one of those being FTP servers. Sometimes, luck will prevail, and anonymous logins will be enabled, meaning anyone can just log in. But more often than not, a valid username and password will be required. But there are several methods to brute-force FTP credentials and gain server access.
