The WannaCry attack exposed our vulnerabilities

Real Vulnerabilities: Cybersecurity and how VEP reform makes us all safer

Some of our critical vulnerabilities were exposed last weekend, as a ransomware attack took unpatched systems by surprise. These vulnerabilities put users and businesses at significant risk, disabling computer systems at hospitals and businesses around the world.

At the same time, exploiting these same vulnerabilities can also be useful for law enforcement and intelligence operations. It’s important to weigh many factors when the government decides what to do.

The Vulnerabilities Equities Process (VEP) is the U.S. government’s process for reviewing and coordinating the disclosure of new vulnerabilities learns about. The VEP remains shrouded in secrecy, and is in need of process reforms to ensure transparency, accountability, and oversight.

Quantum up close: what is a browser engine and how does it work?

Quantum Up Close: What is a browser engine and how does it work?

It’s pretty easy to see the browser as a single black box, sort of like a TV — data goes in, and the black box figures out what to display on the screen to represent that data. The question today is: How? What are the steps that turn data into the web pages we see?

Debugging Web Push in Mozilla Firefox

One of the challenges with Web Push implementation issues is trying to figure out what went wrong. Web Push has a large number of “moving parts”, systems and components that need to work together in order for your message to be successfully sent and received.

While this article can’t address all the reasons that a given Push message might fail, JR Conlin provides tools and guidance for the more common problems.

April 27, 2017: WebAssembly: The Whole Story

Posted on April 27, 2017 by newsletter-archive

WebAssembly: The Whole Story

WebAssembly (.wasm) is a new low-level, assembly-like language that can run in modern web browsers at near-native speeds. It is designed to work alongside JavaScript, and it provides a compilation target for languages like C/C++ so they can run on the web.

We put together a page to talk about what it is and how it’s used.
