8 years ago at SHA2017, the horusscenario was presented. A Theoretical attack through PV-installations to take down the european energy grid. Since that day, a lot of things have changed, both for the better and for the worse.
During the session, we will look back into the horusscenario with today's knowledge and revisit if the attack is still feasible. (Spoiler: I was right... and it has mainly gotten worse since then...)
During the session we will look back on what was said in 2017 and what we know now to be true and have seen in practice. We will also reflect on where we currently are and where we stood back then and if we made any real progress in that regard. Topics discussed will be:
- Was the theoretical analysis correct? and are there any additional nuances there? more recent examples in practice?
- We hacked SMA back then because we thought they were most secure. Have any other grid-ending vulnerabilities in PV-installations popped up since then?
- Are we better off today, then we were back then?
- Prophesising the future: where are we headed with this attack?
