Since the Link-All LAU-G150-C Optical Network Terminal isn’t documented anywhere, I thought this was a great opportunity to practice some hardware hacking…

Nobody cares about the security tools you build. Here’s how to avoid getting sucked into onboarding hell with frictionware, and actually get traction.

Many cybersecurity programmes fall into a trap of creating more and more (busy)work, eventually consuming a majority of resources and attention. In my first post in a series on cybersecurity (anti)patterns, I discuss why we end up with busywork generators and how to avoid them.

Why hack one device, when you can hack all of them? By reverse-engineering and finding vulnerabilities in user-machine association flows for smart weighing machines, I was able to take over millions of internet-connected health devices. Hardware and web security are two halves of modern smart device security, and learning to hack both can yield impressive and scary results.

By chaining various messaging APIs in browsers and browser extensions, I demonstrate how we can jump from web pages to “universal code execution”, breaking both Same Origin Policy and the browser sandbox. I provide two new vulnerability disclosures affecting millions of users as examples. In addition, I demonstrate how such vulnerabilities can be discovered at scale with a combination of large dataset queries and static code analysis.
