    WSJT

    WSJT

    Weak signal ham radio communication

    The WSJT project implements software for amateur radio communication using state-of-the-art digital techniques. Typical applications involve "DXing" at LF, MF, HF, and VHF+ frequencies, including meteor scatter and EME ("moonbounce"). Major emphasis is placed on weak-signal techniques. Summary Program Descriptions: WSJT-X supports the communication protocols FST4, FT4, FT8, JT4, JT9, JT65, Q65, MSK144, WSPR, FST4W, and Echo, each optimized for different sorts of radio-wave propagation. MAP65 and QMAP are designed for EME at VHF and higher frequencies. MAP65 provides a panoramic, polarization-matching receiver for the Q65 and JT65. modes. QMAP works together with WSJT-X to provide a panoramic receiver for Q65 modes covering a 90 kHz sub-band. Programs WSJT and WSPR are interesting primarily for historical reasons. They are superseded by WSJT-X.

    Blank Grabber

    Blank Grabber

    The most powerful stealer written in Python 3

    Blank Grabber is an archived Python information-stealing malware project presented as a configurable grabber with a graphical builder. The repository lists capabilities related to credential theft, session theft, browser data collection, system information capture, screenshots, webcam capture, persistence, evasion, and exfiltration. Although the README includes an educational disclaimer, the tool’s stated behavior is clearly harmful outside isolated and authorized security research. It should not be used as a normal utility, administration tool, or learning project for general users. The safest way to describe it is as a malware sample for defensive analysis, detection engineering, and awareness of common stealer techniques. It is no longer actively maintained in the original repository.

    qBittorrent RuTracker plugin

    qBittorrent RuTracker plugin

    qBittorrent search engine plugin for rutracker

    qBittorrent RuTracker plugin is a lightweight search engine extension designed to integrate the RuTracker torrent index directly into the qBittorrent client, allowing users to search for torrents without leaving the application interface. The plugin follows qBittorrent’s official search plugin architecture and is implemented as a Python script that communicates with the RuTracker website to retrieve and display search results. By embedding this functionality into the client, it streamlines the torrent discovery process and reduces the need for manual browsing across external websites. The plugin requires users to authenticate with RuTracker credentials, enabling access to content that may otherwise be restricted or hidden behind login requirements. It is designed to be simple to install and configure, typically involving placing the script in the appropriate directory and editing credentials.

    Please note that OWFS source code, and all Issue/Tickets/merge requests have now been moved to https://github.com/owfs/owfs/. Developer mailing lists will still be kept at Sourceforge. ---- OWFS -- 1-Wire file system. Use the Dallas 1-Wire and iButton chips with standard filesystem commands. Create temperature loggers. Monitor everything. OWHTTPD -- same system, only used as a light weight web server. OWFS is also ported to embedded routers, Mac OSX and Windows. Basically you can use these inexpensive little sensors and other chips with very simple wiring to sense and control the physical environment. The interface is very flexible -- everything from a web browser, to read and writing directly to the chip's "file" to integrating with your programs -- even over the internet. There is a growing number of 1-wire sensors: temperature, voltage, humidity, light, ultraviolet, pressure, thermisters, thermocouples, programmable microcontrollers, relays, lights, LCD panels, etc

    PySilon Malware

    PySilon Malware

    Advanced RAT written in Python language

    PySilon is a Python-based remote access malware project controlled through Discord. The repository describes it as an advanced RAT with a GUI builder and many remote-control modules. Its capabilities include screen capture, process control, file access, system information collection, input monitoring, browser data extraction, and disruptive system actions. Because those functions can be used to compromise other people’s computers, this project is high-risk and should only be discussed or studied in isolated, authorized security research environments. The repository’s own disclaimer frames the material as educational while placing responsibility on the user. It is best categorized as malware for defensive analysis, threat research, and understanding abuse patterns, not as a normal administration tool.
