    Arduino core for the ESP32

    Arduino core for the ESP32

    Arduino core for the ESP32

    ESP32 is a single 2.4 GHz Wi-Fi-and-Bluetooth SoC (System On a Chip) designed by Espressif Systems. ESP32 is designed for mobile, wearable electronics, and Internet-of-Things (IoT) applications. It features all the state-of-the-art characteristics of low-power chips, including fine-grained clock gating, multiple power modes,and dynamic power scaling. For instance, in a low-power IoT sensor hub application scenario, ESP32 is woken-up periodically and only when a specified condition is detected. The low-duty cycle is used to minimize the amount of energy that the chip expends. The output of the power amplifier is also adjustable, thus contributing to an optimal trade-off between communication range, data rate and power consumption. The ESP32 series is available as a chip or module. You can use Arduino-ESP32 Online Documentation to get all information about this project.

    High performance, open-source, cross-platform RandomX, KawPow, CryptoNight, and AstroBWT CPU/GPU miner, RandomX benchmark, and stratum proxy. XMRig is a high-performance, open-source, cross-platform RandomX, KawPow, CryptoNight, and AstroBWT unified CPU/GPU miner and RandomX benchmark. Official binaries are available for Windows, Linux, macOS, and FreeBSD. The preferred way to configure the miner is the JSON config file as it is more flexible and human-friendly. The command-line interface does not cover all features, such as mining profiles for different algorithms. Important options can be changed during runtime without miner restart by editing the config file or executing API calls.

    box64

    box64

    Linux Userspace x86_64 Emulator with a twist, targeted at ARM64 Linux

    Box86 lets you run x86 Linux programs (such as games) on non-x86 Linux systems, like ARM (the host system needs to be 32bit little-endian). Because box86 uses the native versions of some “system” libraries, like libc, libm, SDL, and OpenGL, it’s easy to integrate and use with most applications, and performance can be surprisingly high in some cases. Many games already work without much tweaking, for example: WorldOfGoo, Airline Tycoon Deluxe, and FTL. Many of the GameMaker Linux games also run fine. (There’s a long list, among them are Undertale, A Risk of Rain, or Cook Serve Delicious.) Box64 is the 64bits version of Box86. It is used to run x86_64 binaries on ARM64 (i.e. aarch64) Linux. There are some YouTube channels where you can see box86 and box64 in action: MicroLinux, PILabs, and The Byteman at least.

    ESP8266 Deauther Version 2

    ESP8266 Deauther Version 2

    Affordable WiFi hacking platform for testing and learning

    Scan for WiFi devices, block selected connections, create dozens of networks and confuse WiFi scanners! Version 3 is in development. It is stable to use, but it is very different. It is command-line based, which allows it to offer not just more features, but make them more customizable. This software allows you to easily perform a variety of actions to test 802.11 wireless networks by using an inexpensive ESP8266 WiFi SoC (System On A Chip). The main feature, the deauthentication attack, is used to disconnect devices from their WiFi network. No one seems to care about this huge vulnerability in the official 802.11 WiFi standard, so I took action and enabled everyone who has less than 10 USD to spare to recreate this project. I hope it raises more attention on the issue. In 2009 the WiFi Alliance actually fixed the problem (see 802.11w), but only a few companies implemented it into their devices and software.

    libusb

    libusb

    A cross-platform library to access USB devices

    libusb is a library for USB device access from Linux, macOS, Windows, OpenBSD/NetBSD, Haiku and Solaris userspace. It is written in C (Haiku backend in C++) and licensed under the GNU Lesser General Public License version 2.1 or, at your option, any later version. libusb is a C library that provides generic access to USB devices. It is intended to be used by developers to facilitate the production of applications that communicate with USB hardware. Using a single cross-platform API, it provides access to USB devices on Linux, macOS, Windows, etc. No special privilege or elevation is required for the application to communicate with a device. All versions of the USB protocol, from 1.0 to 3.1 (latest), are supported. libusb is abstracted internally in such a way that it can hopefully be ported to other operating systems.

    ZMap

    ZMap

    ZMap is a fast single packet network scanner for network surveys

    ZMap is a fast single packet network scanner designed for Internet-wide network surveys. On a typical desktop computer with a gigabit Ethernet connection, ZMap is capable scanning the entire public IPv4 address space in under 45 minutes. With a 10gigE connection and PF_RING, ZMap can scan the IPv4 address space in under 5 minutes. ZMap operates on GNU/Linux, Mac OS, and BSD. ZMap currently has fully implemented probe modules for TCP SYN scans, ICMP, DNS queries, UPnP, BACNET, and can send a large number of UDP probes. If you are looking to do more involved scans, e.g., banner grab or TLS handshake, take a look at ZGrab 2, ZMap's sister project that performs stateful application-layer handshakes. ZDNS is a utility for performing fast DNS lookups, such as completing an A lookup for all names in a zone file, or collecting CAA records for a large number of websites. ZDNS contains its own recursive resolver and supports A, AAAA, ANY, AXFR, CAA, CNAME, DMARC, MX, NS, PTR, TXT, etc.

    POSIX Threads for Windows

    An implementation of the POSIX threads API for Windows

    Also known as "pthreads-win32", POSIX Threads for Windows implements a large subset of the threads related API from the Single Unix Specification Version 3. Conformance and quality are high priorities of this mature library. Development began in 1998 and has continued with numerous significant professional contributions. Please note:- whilst PThreads4W can be built and run by it, MinGW64 includes it's own default POSIX Threads library called "winpthreads". The two are not compatible and in order to build and run PThreads4W (formerly PThreads-WIn32) MinGW64 must be installed without win32pthreads. If you want or need to build and run with PThreads4W then you need to choose win32 threading instead of POSIX when you install MinGW64 to not install the conflicting winpthreads include and library files.
