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.

BadUSB attacks are efficient and deadly. This article explains how to deliver such an attack, describes in detail the preparation of a malicious flash drive required for it, provides code that must be written on this device, and discusses how to make Windows and Linux users plug your ‘memory stick’ into their computers.

Some people say that eavesdropping is bad. But for many security specialists, traffic sniffing is a profession, not a hobby. For some reason, it’s believed that this process requires special expensive equipment, but today, I will show how network traffic can be intercepted using regular crocodile clips.

Even if you take efforts to protect the safety of your data, don’t attach sheets with passwords to the monitor, encrypt your hard drive, and always lock your computer before leaving it unattended, this doesn’t guarantee that your information is safe. Your RAM can be easily dumped using a simple memory stick, and today I will explain in detail how to do this.

Last year, I discovered a binary bug in the AdGuard driver. Its ID in the National Vulnerability Database is CVE-2022-45770. I was disassembling the ad blocker and found a way to use the identified vulnerability for local privilege escalation. As a bonus, this article gives insight into the low-level Windows structure.
