Watch Out! This New Web Exploit Can Crash and Restart Your iPhone

Watch Out! This New Web Exploit Can Crash and Restart Your iPhone
Sep 17, 2018
It's 2018, and just a few lines of code can crash and restart any iPhone or iPad and can cause a Mac computer to freeze. Sabri Haddouche , a security researcher at encrypted instant messaging app Wire, revealed a proof-of-concept (PoC) web page containing an exploit that uses only a few lines of specially crafted CSS & HTML code. Beyond just a simple crash, the web page, if visited, causes a full device kernel panic and an entire system reboot. The Haddouche's PoC exploits a weakness in Apple's web rendering engine WebKit , which is used by all apps and web browsers running on the Apple's operating system. Since the Webkit issue failed to properly load multiple elements such as "div" tags inside a backdrop filter property in CSS, Haddouche created a web page that uses up all of the device's resources, causing shut down and restart of the device due to kernel panic. You can also watch the video demonstration published by the researcher, which s

Mozilla's Firefox OS, the mobile operating system from the company that makes the Firefox browser build entirely on open web standards and having ability to beat Android or iOS.  Firefox OS is Mozilla's ambitious attempt to build an operating system that brings more openness to the walled gardens of Apple's iOS and Google's Android.

Firefox OS written with basic HTML, CSS, and JavaScript Mozilla has also added some extra hooks to Firefox OS that allow developers to access a phone's hardware via HTML

Making Sense of Operational Technology Attacks: The Past, Present, and Future

Making Sense of Operational Technology Attacks: The Past, Present, and Future
Mar 21, 2024Operational Technology / SCADA Security
When you read reports about cyber-attacks affecting operational technology (OT), it's easy to get caught up in the hype and assume every single one is sophisticated. But are OT environments all over the world really besieged by a constant barrage of complex cyber-attacks? Answering that would require breaking down the different types of OT cyber-attacks and then looking back on all the historical attacks to see how those types compare.  The Types of OT Cyber-Attacks Over the past few decades, there has been a growing awareness of the need for improved cybersecurity practices in IT's lesser-known counterpart, OT. In fact, the lines of what constitutes a cyber-attack on OT have never been well defined, and if anything, they have further blurred over time. Therefore, we'd like to begin this post with a discussion around the ways in which cyber-attacks can either target or just simply impact OT, and why it might be important for us to make the distinction going forward.
