mCaptcha is a proof-of-work based captcha system described as privacy focused and fully automated. It states that it does not track or profile users and does not use IP addresses for rate limiting. The project offers an xCaptcha drop-in replacement, and its APIs are described as compatible with reCAPTCHA and hCaptcha. A guide covers installing the captcha on a website.
Rizin is a free and Open Source Reverse Engineering Framework. It uses a shell-like command-line environment for analyzing binaries, with automatic signature detection to match unnamed functions against FLIRT signatures. Projects for saving and loading Rizin sessions are in beta, and Cutter is Rizin's official graphical user interface. A package manager for downloading, compiling and installing plugins is still in early development.
unblob is an extraction suite that parses unknown binary blobs for more than 30 archive, compression and file-system formats. It extracts content recursively and carves out unrecognized chunks. It is free under the MIT license, offers a command line interface and can be used as a Python library. It was developed and is maintained by ONEKEY.
Lucia is a developer resource for coding, documentation, communities, security research, or software tools.
Proxy Check is a proxy detection API offered under free and paid plans. It provides IP data such as network, privacy and operator information, and the documentation describes a v3 API with support for the v2 API until 2035.
A guide introducing Web Authentication (WebAuthn), a W3C and FIDO specification that lets servers register and authenticate users using public key cryptography instead of passwords. It explains how credentials work, with a private key stored on the user's device and a public key sent to the server, and covers registering credentials and authenticating with them.
Reverse Engineering challenges is a collection of reverse engineering exercises contrived by Dennis Yurichev. The challenges are organized by level, type, architecture and operating system, with levels ranging from 1 to 3. The site also offers an about page.
