NSA to release its GHIDRA reverse engineering tool for free

Jan 07, 2019
The United States' National Security Agency (NSA) is planning to release its internally developed reverse engineering tool for free at the upcoming RSA security conference 2019 that will be held in March in San Francisco. The existence of the framework, dubbed GHIDRA, was first publicly revealed by WikiLeaks in CIA Vault 7 leaks, but the tool once again came to light after Senior NSA Adviser Robert Joyce announced to publicly release the tool for free in his RSA Conference session description. Reverse engineering tool is a disassembler, for example, IDA-Pro, that help researchers identify certain portions of a program to see how they work by reading information like its processor instructions, instruction lengths, and more. GHIDRA is a Java-based reverse engineering framework that features a graphical user interface (GUI) and has been designed to run on a variety of platforms including Windows, macOS, and Linux operating systems, and also supports a variety of processor ...
WebAssembly — New Standard for Powerful and Faster Web Apps

WebAssembly — New Standard for Powerful and Faster Web Apps

Jun 23, 2015
Google, Apple, Microsoft , and Mozilla have joined hands to create code for use in the future web browsers that promises up to 20 times faster performance. Dubbed WebAssembly (or wasm for short), a project to create a new portable bytecode for the Web that will be more efficient for both desktop as well as mobile web browsers to parse than the complete source code of a Web page or an application. Bytecode is actually a machine-readable instruction set that is faster for web browsers to load than high-level languages. WebAssembly — A New File Format to Compile Code At the moment, browsers use JavaScript to interpret the code and allow functionality on websites such as dynamic content and forms. By default, JavaScript files are downloaded from the server and then compiled by the JavaScript engine in the web browser. However, improvements have been made to load times via Asm.js — the stripped-down JavaScript dialect described as an "assembly language for ...
Your Risk Scores Are Lying: Adversarial Exposure Validation Exposes Real Threats

Your Risk Scores Are Lying: Adversarial Exposure Validation Exposes Real Threats

Mar 11, 2025Breach Simulation / Penetration Testing
In cybersecurity, confidence is a double-edged sword. Organizations often operate under a false sense of security , believing that patched vulnerabilities, up-to-date tools, polished dashboards, and glowing risk scores guarantee safety. The reality is a bit of a different story. In the real world, checking the right boxes doesn't equal being secure. As Sun Tzu warned, "Strategy without tactics is the slowest route to victory. Tactics without strategy is the noise before defeat." Two and a half millennia later, the concept still holds: your organization's cybersecurity defenses must be strategically validated under real-world conditions to ensure your business's very survival. Today, more than ever, you need Adversarial Exposure Validation (AEV) , the essential strategy that's still missing from most security frameworks. The Danger of False Confidence Conventional wisdom suggests that if you've patched known bugs, deployed a stack of well-regarded security tools, and passed the nec...
