Hacking LED Wristbands: A ‘Lightning’ Recap of RF Security Basics

We’re always eager for new research and learning opportunities, but this time, serendipitously, the opportunity found us. At the closing party of the Hack In The Box Amsterdam conference — where we presented our industrial radio research and ran a CTS contest — we were given LED wristbands to wear. They’re flashing wristbands meant to enhance the experience of an event, party, or show. At the beginning, we were not interested in the security impact; we just wanted to learn. Later on, however, we discovered that the RF link was used to transport an industrial protocol: DMX512 (Digital MultipleX 512), the same protocol used to pilot large light exhibitions.

From BinDiff to Zero-Day: A Proof of Concept Exploiting CVE-2019-1208 in Internet Explorer

Last June, I disclosed a use-after-free (UAF) vulnerability in Internet Explorer (IE) to Microsoft. It was rated as critical, designated as CVE-2019-1208, and then addressed in Microsoft’s September Patch Tuesday. I discovered this flaw through BinDiff (a binary code analysis tool) and wrote a proof of concept (PoC) showing how it can be fully and consistently exploited in Windows 10 RS5.

A more in-depth analysis of this vulnerability is in this technical brief. As mentioned, CVE-2019-1208 is a UAF vulnerability. This class of security flaws can corrupt valid data, crash a process, and, depending on when it is triggered, can enable an attacker to execute arbitrary or remote code. In the case of CVE-2019-1208, an attacker successfully exploiting this vulnerability could gain the same rights as the current user in the system. If the current user has administrative privileges, the attacker can hijack the affected system — from installing or uninstalling programs and viewing and modifying data to creating user accounts with full privileges.
