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 -

SeedCrackerX
Minecraft mod designed to reverse-engineer
SeedcrackerX is a Minecraft mod designed to reverse-engineer and determine a world’s seed by analyzing in-game structures and environmental data. It operates by collecting information from structures such as shipwrecks, temples, and monuments, then using that data to progressively narrow down possible seeds until the correct one is identified. The mod automates much of this process, initiating cracking procedures once sufficient data has been gathered, often requiring only exploration of specific structures. It includes a graphical configuration interface that allows users to control which structures are used and how data is collected. The system can also integrate with a shared database to contribute discovered seeds, enabling collaborative data gathering across users. Advanced features include brute-force algorithms that refine seed candidates based on structural patterns and hashed seed calculations. -

Wi-Fi Cracking
Crack WPA Wi-Fi routers with Airodump-ng and Aircrack-ng Hashcat
Crack Wi-Fi networks that are secured using weak passwords. It is not exhaustive, but it should be enough information for you to test your own network's security or break into one nearby. Begin by listing wireless interfaces that support monitor mode. If you do not see an interface listed then your wireless card does not support monitor mode. Start listening to 802.11 Beacon frames broadcast by nearby wireless routers using your monitor interface. WPA/WPA2 uses a 4-way handshake to authenticate devices to the network. You don't have to know anything about what that means, but you do have to capture one of these handshakes in order to crack the network password. These handshakes occur whenever a device connects to the network. The final step is to crack the password using the captured handshake. If you have access to a GPU, it is highly recommended to use hashcat for password cracking. -

Gobuster
Directory/File, DNS and VHost busting tool written in Go
Gobuster is a tool used to brute-force. This project is born out of the necessity to have something that didn't have a fat Java GUI (console FTW), something that did not do recursive brute force, something that allowed me to brute force folders and multiple extensions at once, something that compiled to native on multiple platforms, something that was faster than an interpreted script (such as Python), and something that didn't require a runtime. Provides several modes, like the classic directory brute-forcing mode, DNS subdomain brute-forcing mode, the mode that enumerates open S3 buckets and looks for existence and bucket listings, and the virtual host brute-forcing mode (not the same as DNS!). Since this tool is written in Go you need to install the Go language/compiler/etc. Full details of installation and set up can be found on the Go language website. Once installed you have two options. You need at least go 1.16.0 to compile gobuster. -

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. -

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. -
