    Osquery

    Osquery

    SQL operating system instrumentation and monitoring framework

    Osquery is an operating system instrumentation framework for Windows, OS X (macOS), Linux, and FreeBSD. The tools make low-level operating system analytics and monitoring both performant and intuitive. Osquery exposes an operating system as a high-performance relational database. This allows you to write SQL queries to explore operating system data. With osquery, SQL tables represent abstract concepts such as running processes, loaded kernel modules, open network connections, browser plugins, hardware events or file hashes.Osquery queries your devices like a database. Osquery uses basic SQL commands to leverage a relational data-model to describe a device. Frequently, attackers will leave a malicious process running but delete the original binary on disk. This query returns any process whose original binary has been deleted, which could be an indicator of a suspicious process.

    Wi-PWN

    Wi-PWN

    ESP8266 firmware for performing deauthentication attacks

    ESP8266 firmware for performing deauthentication attacks, with ease. Wi-PWN is a firmware that performs death attacks on cheap Arduino boards. The ESP8266 is a cheap microcontroller with built-in Wi-Fi. It contains a powerful 160 MHz processor and it can be programmed using Arduino. A deauthentication attack is often confused with Wi-Fi jamming, as they both block users from accessing Wi-Fi networks. The 802.11 Wi-Fi protocol contains a so-called deauthentication frame. It is used to disconnect clients safely from a wireless network. Because these management packets are unencrypted, you just need the MAC to address of the Wi-Fi router and of the client device which you want to disconnect from the network. You don’t need to be in the network or know the password, it’s enough to be in its range. With the 802.11w-2009 updated standards, management frames are encrypted by default.

    WipeFreeSpace

    WipeFreeSpace

    Secure wiping/shredding of free disk space with many methods

    WipeFreeSpace is a program to securely erase/wipe/overwrite/shred the free space on file systems WITHOUT DESTROYING EXISTING FILES, to prevent recovery of deleted sensitive data. This allows protecting the user's privacy when e.g. selling the drive or the whole computer. The following filesystems are supported: - Ext2/3/4, - NTFS, - XFS, - ReiserFSv3/4, - FAT12/16/32, - MinixFS1/2, - JFS, - HFS/HFS+, - OCFS. The following wiping methods are supported: Gutmann-like, random, Schneier, DoD. Additionally, WipeFreeSpace can finalize wiping the filesystem by writing blocks of zeros, which is friendly for sparse files, virtual systems and other places where zeroed-out space is not physically allocated. See the project homepage https://wipefreespace.sourceforge.io and the project Wiki in the menu above. To prevent clear-text data from being left on the drive in the first place, you can use LibSecRm (https://libsecrm.sourceforge.io), which wipes the data on-the-fly.

    BerserkArch

    A bleeding-edge, security-centric Arch-based Linux distribution.

    BerserkArch is a security-focused, performance-tuned Linux operating system (OS) based on Arch Linux, designed for developers, hackers, and technical users. A bleeding-edge, security-centric Arch-based Linux distribution crafted for hackers, developers, and nerds alike. Following the Arch Linux philosophy, it is designed to be highly customizable, allowing users to build their environment with only the components they need, rather than having a lot of pre-installed software like some other security distributions (e.g., Kali Linux). 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.
