Cybersecurity Using C# to steal tokens and gain system permissions

Intro Grzegorz Tworek recently published some C code demonstrating how to steal and impersonate Windows tokens from a process. The standard way to do this is with the OpenProcess, OpenProcessToken, DuplicateTokenEx, and ImpersonateLoggedOnUser APIs. Grzegorz shows how to achieve the same using Nt* APIs, specifically NtOpenProcess, NtOpenProcessToken, NtDuplicateToken, and NtSetInformationThread. Because I’m a C# junky, I…

Cybersecurity BadUSB Principles and STM32 HID Tutorial (Source Code and GitHub Link)

What is BadUSB? Using the STM32F407 development board, we’ll study HID device development and implement a low-cost BadUSB. This article uses the development board for testing. Those with the means can also create a PCB prototype and print the enclosure to create a highly realistic BadUSB.BadUSB is an attack that masquerades as a USB HID…

Cybersecurity MCP Security Vulnerabilities: Critical Risks Every Developer Must Know

Model Context Protocol (MCP) is gaining traction, but critical security gaps remain. This guide explores common MCP vulnerabilities in the 2025-06-18 release — from misconfigurations and credential leaks to command injection and remote code execution — helping developers secure their MCP deployments. MCP adoption is picking up quickly, so I have been digging into the…

Cybersecurity Use io_uring to evade security detection and targeted detection.

This article explores how ARMO researchers leveraged the io_uring mechanism to bypass popular Linux security monitoring tools such as Falco and Tetragon. It also demonstrates the workings of the open-source attack tool Curing, explaining its core calls, exploitation process, and potential defense strategies.
