HDL / Bitstreams and other ramblings
I started reading this article instead of just skimming it when I came across the use of "hardware definition language" as hardware description language is considerably more common in the 21st century.  Calling a bitstream HDL is like calling an ELF binary file assembly language code at best. Bitstreams are incredibly difficult to hack, though not impossible. Machine code for a CPU is easy, bitstreams are a whole different animal, making exploiting FPGAs much more difficult and typically requires completely re-writing the NVM on which the bitstream resides via JTAG or some other means. Specialized hardware is almost always required to exploit an FPGA, except in the increasingly common scenarios where USB to JTAG interfaces are put on the product itself just as they are on many developer kits.

FPGA experts are not common. Care needs to be taken in not only the development of the HDL but also the electronic circuit design around the FPGA to harden a system. Careless HDL developers using reference hardware designs from FPGA manufactureres will result in many more exploits akin to those found to date.

The 10 Most Impactful Types of Vulnerabilities for Enterprises Today
Managing system vulnerabilities is one of the old est - and most frustrating - security challenges that enterprise defenders face. Every software application and hardware device ships with intrinsic flaws - flaws that, if critical enough, attackers can exploit from anywhere in the world. It's crucial that defenders take stock of what areas of the tech stack have the most emerging, and critical, vulnerabilities they must manage. It's not just zero day vulnerabilities. Consider that CISA's Known Exploited Vulnerabilities (KEV) catalog lists vulnerabilitlies in widely used applications that are "actively exploited," and most of them are flaws that were discovered several years ago and have been fixed. There are also emerging vulnerabilities in 5G networks, cloud infrastructure, Edge applications, and firmwares to consider.
