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…

MCP adoption is picking up quickly, so I have been digging into the implementations, especially around security and noticed some serious risks that could become disasters if not handled properly. The new MCP 2025-06-18 spec attempts to address some issues but the reality of most servers with boring security debt will bite you when you…

Additionally, the ARMO team has also open-sourced the io_uring-based rootkit tool – Curing:https://github.com/armosec/curing About…
