How To: Compromise a Web Server & Upload Files to Check for Privilege Escalation, Part 2
In the first guide, we laid the groundwork for our ultimate goal of uploading and running the unix-privesc-check script on our target. We identified an input field vulnerable to SQL injection and utilized Sqlmap to set up a file stager on the server. Now, we're ready to upload files and execute the script, so we can identify any misconfigurations that could lead to privilege escalation.
How To: Discover & Attack Raspberry Pis Using Default Credentials with Rpi-hunter
When setting up a Raspberry Pi, it's easy to overlook changing the default password. Like many IoT devices, the Raspberry Pi's default Raspbian operating system installs with a widely-known default password, leaving the device vulnerable to remote access. Using a tool called rpi-hunter, hackers can discover, access, and drop custom payloads on any weak Pi connected to the same network.
How To: Scan, Fake & Attack Wi-Fi Networks with the ESP8266-Based WiFi Deauther

How to Hack Wi-Fi: Stealing Wi-Fi Passwords with an Evil Twin Attack
While Wi-Fi networks can be set up by smart IT people, that doesn't mean the users of the network 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. This forces the victim to connect to the fake network and supply the Wi-Fi password to regain internet access.
