We found unauthenticated remote code execution on an industrial PLC without ever touching the hardware.
 
By unpacking publicly available firmware for the KUNBUS Revolution Pi, our Adam Bromiley discovered four vulnerabilities. Two of them allowed RCE with no authentication required.
 
We dug into a misconfigured Node-RED instance, bypassed authentication in PiCtory, and chained bugs together to gain full control. This could affect safety-critical systems in the real world.
 
The upside? Disclosure was handled properly. KUNBUS and CISA coordinated the response well, and advisories and fixes for all four CVEs are now live.

The #blackout on April 28 doesn’t seem to be the work of a cyberattack 🤞🏼.

However, given the current geopolitical climate, the cause doesn’t matter to many.

Like a fire drill, this is the closest we’ve come to experiencing the effects of such an attack, and many have realized they are not ready for when the real thing comes.

Continued thread

The steps are simple:
- download the corresponding images;
- write the image to the drive, expand the filesystem;
- install the drive and start.

Then you have to configure your network and the old OT hardware can reliably do its job (incl. analysis/remote maintenance for soc/siem) for many years to come, including the possibility of updates either via network or USB stick. 3/3

Continued thread

The hardware was refurbished, including a quick analysis of the equipment. I quickly realized that modern and up-to-date network firewall firmware could be installed on both devices without much effort and high costs. Since #BSDRP , #OPNSense and #pfSense no longer support x86 (i586/i686) architectures, the choice fell on the current #OpenWrt and #DDWRT versions for x86 (i586/i686) architectures. 2/3

One of the key statements was as follows: “We no longer receive support for the OT network hardware and cannot simply replace it!” I asked for the manufacturer and type designation:

- Securepoint Black Dwarf V. 1.0 - CPU VIA Eden - 1 GB RAM
- Securepoint RC200 V. 1.1 - CPU Intel N270 - 1 GB RAM

I went on a shopping tour and, after the first test of the Securepoint RC200, experienced a real surprise (not funny). Back to the actual problem. 1/3

⚠️ OT cybersecurity is officially a board-level issue.

Regulators are cracking down on companies that fail to secure critical infrastructure:
🏭 Operational tech is now in the crosshairs
💣 Most OT attacks start in IT networks
📛 Poor segmentation = high risk
⚖️ Legal & financial accountability is coming

Boards can’t afford to treat OT like an afterthought. The next breach won’t just be a tech failure — it’ll be a leadership failure.
