    VeraCrypt

    VeraCrypt

    Open source disk encryption with strong security for the Paranoid

    VeraCrypt is a free disk encryption software brought to you by IDRIX (https://www.idrix.fr) and based on TrueCrypt 7.1a. It adds enhanced security to the algorithms used for system and partitions encryption making it immune to new developments in brute-force attacks. It also solves many vulnerabilities and security issues found in TrueCrypt. This enhanced security adds some delay ONLY to the opening of encrypted partitions without any performance impact to the application use phase. This is acceptable to the legitimate owner but it makes it much harder for an attacker to gain access to the encrypted data. All released files are PGP signed with key ID=0x680D16DE, available on key servers and downloadable at https://www.idrix.fr/VeraCrypt/VeraCrypt_PGP_public_key.asc VeraCrypt can mount TrueCrypt volumes. It also can convert them to VeraCrypt format. Documentation: https://www.veracrypt.fr/en/Documentation.html FAQ : https://www.veracrypt.fr/en/FAQ.html

    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.

    thc-hydra

    thc-hydra

    Shows how easy it would be to gain unauthorized access to a system

    Number one of the biggest security holes are passwords, as every password security study shows. This tool is a proof of concept code, to give researchers and security consultants the possibility to show how easy it would be to gain unauthorized access from remote to a system. There are already several login hacker tools available, however, none does either support more than one protocol to attack or support parallelized connects. It was tested to compile cleanly on Linux, Windows/Cygwin, Solaris, FreeBSD/OpenBSD, QNX (Blackberry 10) and MacOS. However the module engine for new services is very easy so it won't take a long time until even more services are supported. Via the command line options you specify which logins to try, which passwords, if SSL should be used, how many parallel tasks to use for attacking, etc. PROTOCOL is the protocol you want to use for attacking, e.g. ftp, smtp, http-get or many others are available.

As an Arch-based distribution, it benefits from the rolling release model, providing users with the latest software versions and kernel updates. BerserkArch is a dist "designed to make you powerful" for specific use cases like reverse-engineering binaries and automating exploits, rather than being an easy-to-use distribution for general beginners.

    ParamIT

    a Toolset for Molecular Mechanical Force Field Parameterization

    ParamIT is a toolkit aiding the development of molecular mechanical force field parameterization of small, drag like, molecules within CHARMM general force field (CGenFF) protocol. The developed toolkit helps the researchers in following ways: 1) automating the creation of multiple input files for quantum and molecular mechanics programs, 2) automating the output analysis and 3) substitute the use of full MM programs with a faster specialized one. The developed tools include: 1) generator of molecule-water complexes with graphical user interface (GUI), 2) semi-automatic frequency analysis using symbolic potential energy distribution matrix and comparison of optimized internal coordinates, 3) GUI for charge fitting with three modes: manual, Monte-Carlo sampling or brute force, and 4) GUI for dihedral terms fitting. The usage of these tools decreases the labor effort, lowers manual input errors and reduces the time needed for accurate MM parameterization efforts.
