Xenos
Windows dll injector
Xenos is a lightweight Windows DLL injector built on top of the Blackbone library that specializes in injecting custom dynamic libraries into target processes for purposes such as modding, testing, or security research. As an application rather than a library, it provides a concrete example of how to leverage Blackbone’s robust process and memory manipulation APIs to perform manual and automated DLL injection into both 32-bit and 64-bit Windows applications. Xenos supports a variety of mapping techniques including manual mapping, and it is configured to work across supported Windows versions from Windows 7 to Windows 10 x64, making it useful for developers and modding communities working with older or newer games and applications. By basing its core functionality on Blackbone, Xenos benefits from the underlying library’s advanced memory manipulation capabilities such as process attachment, memory allocation, and loader-agnostic injection methods. -

Detect It Easy
Program for determining types of files for Windows, Linux and MacOS
Detect It Easy (DiE) is a tool for determining the type and internal features of binary and other file formats. It is widely used by malware analysts, digital forensics investigators, reverse engineers, and security researchers to quickly inspect unknown files and infer their type, architecture, compiler/packer used, and internal structure. DiE supports a large variety of file formats — from common executables (Windows PE, Linux ELF, macOS Mach-O) to archives, mobile packages (APK, IPA), legacy binaries, compressed or packed files, and more — making it a versatile first step in analysis or triage workflows. The tool offers both a graphical user interface as well as a command-line interface, allowing flexible use across environments (desktop, servers, automation). Its detection engine is signature-based, but also includes heuristics that help when signatures are missing or obfuscated. This helps when analyzing packed, compressed, or partially corrupted files. -

mkcert
Zero-config tool to make locally trusted development certificates
mkcert is a simple tool for making locally-trusted development certificates. It requires no configuration. Using certificates from real certificate authorities (CAs) for development can be dangerous or impossible (for hosts like example.test, localhost or 127.0.0.1), but self-signed certificates cause trust errors. Managing your own CA is the best solution, but usually involves arcane commands, specialized knowledge and manual steps. mkcert automatically creates and installs a local CA in the system root store, and generates locally-trusted certificates. mkcert does not automatically configure servers to use the certificates, though, that's up to you. The CA certificate and its key are stored in an application data folder in the user's home. You usually don't have to worry about it, as the installation is automated, but the location is printed by mkcert -CAROOT. -

SimpleX
The first messaging platform operating without user identifiers
Other apps have user IDs: Signal, Matrix, Session, Briar, Jami, Cwtch, etc. SimpleX does not, not even random numbers. This radically improves your privacy. The video shows how you connect to your friend via their 1-time QR-code, in person or via a video link. You can also connect by sharing an invitation link. Temporary anonymous pairwise identifiers SimpleX uses temporary anonymous pairwise addresses and credentials for each user contact or group member. It allows to deliver messages without user profile identifiers, providing better meta-data privacy than alternatives. Many communication platforms are vulnerable to MITM attacks by servers or network providers. To prevent it SimpleX apps pass one-time keys out-of-band when you share an address as a link or a QR code. Double-ratchet protocol. OTR messaging with perfect forward secrecy and break-in recovery. NaCL cryptobox in each queue to prevent traffic correlation between message queues if TLS is compromised. -
