In my free time over the coming weeks and months, I’ll be working on a new version of my pentest dropboxes for IT and OT, and I’ll be turning the projects “Lemon” and “Motion”, which are still on paper, into reality.

And since people keep asking, I don’t have a sponsor and pay for everything out of my own pocket because that’s the only way I can stay creative and independent.

A preview. One will become the current generation of dropboxes again and the other three will become the next generation with other (additional features).

A critical vulnerability in the device’s Lua runtime — an undocumented function —bypasses all sandboxing restrictions and allows arbitrary OS command execution as root. #icssecurity #ics #otsecurity #lua

Two good things:

First, the drive was erased really well, it wouldn't be worth the effort.

Secondly, the device can still be used excellently for demonstration purposes and to explain things.

I got an old router, #pcengines #ALIX 2D2/2D18 with wifi, from a company liquidation (bankrupt). The device was in operation in the field at the tank control and mixing unit. Let's see what artifacts can still be found. #otsecurity #hardware #icsSecuruity
