    Git

    Git

    Fast, scalable, distributed revision control system

    Git is a free, distributed version control system created by Linus Torvalds in 2005 to manage the development of the Linux kernel. It emphasizes speed, data integrity, and support for non-linear workflows, and remains the most popular VCS for collaborative software development. Git is an Open Source project covered by the GNU General Public License version 2 (some parts of it are under different licenses, compatible with the GPLv2). It was originally written by Linus Torvalds with help of a group of hackers around the net. Git is a fast, scalable, distributed revision control system with an unusually rich command set that provides both high-level operations and full access to internals.

    MTProxy

    MTProxy

    Simple MT-Proto proxy

    MTProxy is Telegram’s official MTProto proxy server implementation that enables users to create and run proxy nodes for the Telegram messaging platform, helping people connect securely and reliably when direct access to Telegram is restricted or blocked. It implements the MTProto proxy protocol, which obfuscates encrypted Telegram traffic so it appears indistinguishable from normal HTTPS/TLS flows, making it harder for ISPs or authorities to detect and block Telegram traffic based on signatures. The repository includes C source code, build instructions, and configuration files for compiling and running the proxy on Unix-like systems, with dependencies including OpenSSL and zlib. By launching an MTProxy instance with a secret and configuration file, system administrators can allow clients to connect through custom proxies and generate shareable proxy links for Telegram clients.

    OpenHardwareMonitor

    OpenHardwareMonitor

    Free open source tool for real-time PC hardware sensor monitoring

    Open Hardware Monitor is a free and open source hardware monitoring application designed primarily for personal computers. It provides real-time insights into key system metrics such as temperatures, fan speeds, voltages, load percentages, and clock speeds by reading directly from sensors embedded in CPUs, GPUs, motherboards, and storage devices. The tool supports a wide range of sensor hardware found on modern systems, including Intel and AMD processors, NVIDIA and AMD graphics cards, SMART temperature sensors on storage drives, and many motherboard monitoring chips. Users can view monitored data directly within the application, as customizable desktop gadgets, or through a system tray interface, making it easy to keep an eye on system health at a glance. OpenHardwareMonitor runs without the need for a traditional installation (it can be run portably) and on systems configured with the appropriate runtime (e.g., .NET or Mono).

    Flipper Zero Firmware

    Flipper Zero Firmware

    Flipper Zero firmware source code

    Flipper Zero is a portable multi-tool for pentesters and geeks in a toy-like body. It loves hacking digital stuff, such as radio protocols, access control systems, hardware, and more. It's fully open-source and customizable, so you can extend it in whatever way you like. Flipper Zero is a tiny piece of hardware with a curious personality of a cyber-dolphin. It can interact with digital systems in real life and grow while you use it. Explore any kind of access control system, RFID, radio protocols, and debug hardware using GPIO pins. The idea of Flipper Zero is to combine all the hardware tools you'd need for exploration and development on the go. Flipper was inspired by the pwnagotchi project, but unlike other DIY boards, Flipper is designed with the convenience of everyday usage in mind — it has a robust case, handy buttons, and shape, so there are no dirty PCBs or scratchy pins. Flipper turns your projects into a game, reminding you that development should always be fun.

    YARA

    YARA

    The pattern matching swiss knife for malware researchers

    YARA is a tool aimed at (but not limited to) helping malware researchers to identify and classify malware samples. With YARA you can create descriptions of malware families (or whatever you want to describe) based on textual or binary patterns. Each description, a.k.a rule, consists of a set of strings and a boolean expression which determines its logic. YARA is multi-platform, running on Windows, Linux and Mac OS X, and can be used through its command-line interface or from your own Python scripts with the yara-python extension. YARA-CI may be a useful addition to your toolbelt. This is GitHub application that provides continuous testing for your rules, helping you to identify common mistakes and false positives. If you plan to use YARA to scan compressed files (.zip, .tar, etc) you should take a look at yextend, a very helpful extension to YARA developed and open-sourced by Bayshore Networks.
