Web Browsers still allow drive-by-downloads in 2020

It’s 2020, and numerous browsers still allow drive-by-downloads from what is meant to be secure contexts such as sandboxed iframes. For those unfamiliar with the term, a drive-by-download is when a user visits a site, and a file download is initiated without the user’s interaction. This technique can be used to distribute unwanted software and malicious programs in the hopes that users will accidentally or mistakenly execute the downloads and get infected. New research from ad security firm Confiant shows that secure contexts such as sandboxed iframes can be abused to allow drive-by-downloads…

Browsers represented included Google Chrome, Microsoft Edge, Mozilla Firefox, and WebKit, which is Apple’s browser engine for…

Automatic Table of Contents

Any long page of content with distinct and well marked up content can benefit from a table to contents. A table of contents provides a quick way to jump down the page to the desired section. Of course you can create a table of contents manually, but it may be smart to build it dynamically on-the-fly with JavaScript. This is true for several reasons: It’s easier – write the JavaScript once and it can create the Table on Contents on every page you need it. It’s more reliable – the…

After my post of yesterday, I’ve worked for creating a script to integrate Google Analytics (new version with analytics.js) and Piwik (Piwik is the leading open-source analytics platform similar to Google Analytics.

Automatically the function detects download, email, phone number, external links and tracks them. You can insert in an anchor a code like: <a href=”https://puresourcecode.com/” onclick=”TrackEvent(‘Link to my site’, ‘PSC’,…

Using the UpdateProgress to lock down controls in the browser

If it takes awhile for the server to process the postback (e.g. complex rules or badly written code ), the user may not realize that the server is processing the request. This can lead to all kinds of issues with users that are not savvy or familiar with web applications (multiple clicks, moving off the page, etc.). Consequently, I want to tell the user that the server is processing the request and disable the controls on the page. Let’s break this down into two steps: show a message, and disable…
