About two years ago I announced Winbindex - the Windows Binaries Index. I described how I downloaded all the Windows 10 update packages I could find, and how, with the help of VirusTotal, I was able to generate download links for the files from the update packages that were submitted to the service. If you didn’t read the announcement blog post, I suggest you read it for the motivation behind the project and for the full technical details. Below is a quick recap, followed by the small updates Winbindex got during these two years. After bringing you up to date, I’ll tell you how I was able to generate download links for all files, even those that weren’t submitted to VirusTotal, and what are the limitations of the method I used.

A couple of weeks ago, Windhawk, the customization marketplace for Windows programs, was released. You can read the announcement for more details and for the motivation behind creating it. In this post, I’ll focus on my journey in implementing the technical aspects of Windhawk. If you prefer reading code to reading text, check out the demo implementation.

I indexed all Windows files which appear in Windows update packages, and created a website which allows to quickly view information about the files and download some of them from Microsoft servers. The files that can be downloaded are executable files (currently exe, dll and sys files). Read on for further information.

This is a story about Technion Confessions which begins with me being curious about the identity of the Technion Confessions admin, and ends up with me satisfying my curiosity by using an XSS vulnerability in the Technion course registration system and social engineering.

This blog post is about my journey to understand the current practice of de-anonymization via the clickjacking technique whereby a malicious website is able to uncover the identity of a visitor, including his full name and possibly other personal information. I don’t present any new information here that isn’t already publicly available, but I do look at how easy it is to compromise a visitor’s privacy and reveal his identity, even when he adheres to security best practices and uses an up-to-date browser and operating system.
