    Al-Khaser

    Al-Khaser

    Public malware techniques used in the wild: Virtual Machine, Emulation

    al-khaser is an open-source proof-of-concept security tool that deliberately implements techniques commonly used by real-world malware to test and evaluate the effectiveness of antivirus and endpoint detection and response (EDR) systems. It’s written in C/C++ and designed to execute a wide range of anti-analysis, anti-debugging, anti-virtualization, timing-based evasion, and sandbox detection routines so security researchers and defenders can see how well their tools detect or ignore these behaviors. The project includes checks for debugger presence, stealthy anti-dumping measures, various VM and sandbox artifacts, and process injection techniques, giving you a broad view of how defensive tools respond under stress. al-khaser isn’t malicious by intent — its purpose is to help security teams identify gaps in their detection logic and harden defenses by simulating evasive behaviors without actual payloads.

    GnuPG

    GnuPG

    Complete and free implementation of the OpenPGP standard

    GnuPG (GNU Privacy Guard) is a widely used free software encryption system that implements the OpenPGP standard to provide secure communication and data protection across multiple platforms. It uses a hybrid cryptographic approach combining symmetric encryption for performance with public-key cryptography for secure key exchange and identity verification. The software allows users to encrypt files and messages, create digital signatures, and manage cryptographic keys, making it a foundational tool for privacy-focused workflows. Because it is open source and licensed under the GNU GPL, GnuPG can be freely audited, modified, and redistributed, which has contributed to its adoption in security-sensitive environments. It is primarily command-line driven but can be integrated into email clients, messaging tools, and graphical front-ends for broader usability.

    NanoClaw

    NanoClaw

    A lightweight alternative to Clawdbot / OpenClaw

    Nanoclaw is a lightweight, security-focused personal agent runtime designed as a slimmer alternative to larger “personal assistant” agent stacks, with an emphasis on being easy to audit and safe by default. It runs agent execution inside Apple containers to provide strong isolation boundaries, so individual chats and actions can be sandboxed with tighter filesystem and process separation than a typical single-process bot. The project connects directly to WhatsApp, letting you deploy an assistant that can chat in a familiar interface while still supporting real agent behaviors instead of simple call-and-response prompts. It includes memory so the assistant can retain important context across interactions, enabling more consistent follow-through on ongoing tasks. It also supports scheduled jobs, making it suitable for recurring reminders, periodic automations, and timed workflows without needing an external orchestrator.

    OWASP Juice Shop

    OWASP Juice Shop

    Probably the most modern and sophisticated insecure web application

    OWASP Juice Shop is probably the most modern and sophisticated insecure web application! It can be used in security trainings, awareness demos, CTFs and as a guinea pig for security tools! Juice Shop encompasses vulnerabilities from the entire OWASP Top Ten along with many other security flaws found in real-world applications! Juice Shop is written in Node.js, Express and Angular. It was the first application written entirely in JavaScript listed in the OWASP VWA Directory. The application contains a vast number of hacking challenges of varying difficulty where the user is supposed to exploit the underlying vulnerabilities. The hacking progress is tracked on a score board. Finding this score board is actually one of the (easy) challenges! Apart from the hacker and awareness training use case, pentesting proxies or security scanners can use Juice Shop as a "guinea pig"-application to check how well their tools cope with JavaScript-heavy application frontends and REST APIs.

    HFV (Hidden Folder Virus) Cleaner Pro

    HFV (Hidden Folder Virus) Cleaner Pro

    A Small Utility programmed to destroy Win32:Atraps-PZ[Trojan]

    Many a times when we connect our PenDrive to a PC or Laptop, wedon't see our files and folders, instead see one or multiple shortcuts. Assuming these shortcuts as innocent, we launch them which in turn infects our PC or laptop with a virus which the geeks call Win32:Atraps-PZ[Trojan] Simply speaking, the shortcut creates a backdoor to your system so that it can access all your files,services and privileges within that system & all others connected to it without your permission. This is where HFV comes to help...Simply paste the location of your Infected directory on the box & click Delete virus to get rid of virus. As a safety precaution, keep this software backed up on system as well since the virus which hides all files and creates a shortcut can also hide this software as well. P.S.It can also be used to hide your private data from Neighbors and Roommates;)

    Privacy Badger

    Privacy Badger

    Privacy Badger automatically learns to block invisible trackers

    Privacy Badger is a browser extension that stops advertisers and other third-party trackers from secretly tracking where you go and what pages you look at on the web. If an advertiser seems to be tracking you across multiple websites without your permission, Privacy Badger automatically blocks that advertiser from loading any more content in your browser. To the advertiser, it’s like you suddenly disappeared. Privacy Badger was born out of our desire to be able to recommend a single extension that would automatically analyze and block any tracker or ad that violated the principle of user consent; which could function well without any settings, knowledge, or configuration by the user; which is produced by an organization that is unambiguously working for its users rather than for advertisers; and which uses algorithmic methods to decide what is and isn’t tracking.

    SOPS

    SOPS

    Simple and flexible tool for managing secrets

    sops is an editor of encrypted files that supports YAML, JSON, ENV, INI and BINARY formats and encrypts with AWS KMS, GCP KMS, Azure Key Vault, age, and PGP. For the adventurous, unstable features are available in the develop branch, which you can install from source. To use sops as a library, take a look at the decrypt package. We rewrote Sops in Go to solve a number of deployment issues, but the Python branch still exists under python-sops. We will keep maintaining it for a while, and you can still pip install sops, but we strongly recommend you use the Go version instead. If you're using AWS KMS, create one or multiple master keys in the IAM console and export them, comma separated, in the SOPS_KMS_ARN env variable. It is recommended to use at least two master keys in different regions. If you want to use PGP, export the fingerprints of the public keys, comma separated, in the SOPS_PGP_FP env variable.

    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.

    VisualCodeGrepper V2.3.2

    Code security review tool for C/C++, C#, VB, PHP, Java, PL/SQL, COBOL.

    VCG is an automated code security review tool for C++, C#, VB, PHP, Java, PL/SQL and COBOL, which is intended to speed up the code review process by identifying bad/insecure code. New beta functionality has been added for R. It has a few features that should make it useful. In addition to performing some more complex checks it also has a config file for each language that basically allows you to add any bad functions (or other text) that you want to search for. It attempts to find phrases within comments that can indicate broken code and it provides stats and a pie chart (for the entire codebase and for individual files) showing relative proportions of code, whitespace, comments, 'ToDo'-style comments and bad code. I've tried to produce something which searches intelligently for buffer overflows and signed/unsigned comparison in C, violations of OWASP recommendations in Java code, etc. Current version: 2.3.2
