Attacks on Wi-Fi are extremely diverse: your targets are both client devices and access points who, in turn, can use various protocols and authentication methods. This article presents a simple but effective brute-forcing technique for wireless networks.

Imagine that you are sitting with your computer on an upper floor of a secure building located in the middle of a restricted zone fenced by electrified barbed wire. You feel completely safe: cameras and vigilant security personnel protect you. As of a sudden, you hear suspicious buzzing outside the window, and this sound distracts you for a few seconds. And in these few seconds, a backdoor is installed on your computer, and a hacker located 20 km from you penetrates the corporate network. Sounds fantastic? No way!

In sci-fi movies, hackers often use small pocket devices, less than a cellphone in size, to hack a company’s wireless network, gain access to its servers, and steal passwords. This article gives you a chance to become one of such hackers; all you need for this is a fantastic gadget called Pineapple. Most importantly, you can assemble it yourself, and I will explain in detail how.

Unauthorized access to someone else’s device can be gained not only through a USB port, but also via an Ethernet connection – after all, Ethernet sockets are so abundant in modern offices and public spaces. In this article, I will explain how to penetrate into a local network using a special ‘invisible’ device and how this device operates.

If you have direct access to the target PC, you can create a permanent and continuous communication channel with it. All you need for this is a USB modem that must be slightly modified first. In this article, I will explain in detail how to deliver such an attack.

If you have a chance to plug a specially crafted device to a USB port of the target computer, you can completely intercept its traffic, collect cookies and passwords, and hack the domain controller. The attack is delivered over Wi-Fi, and this article explains how to implement it.
