the actual paper is at:

We had one incident here in Sweden when a complete network went down due to a GPS bug. As PRN32 became enabled, it got selected and tracking data was collected in a sat[32] vector, which is obviously unsafe so it overwrote critical data and crashed. In fact, they all did this within a minute or so as it came up above the horizon. It took a bit of advanced guesswork from my side to find that flaw. It was one of those "blame the solar flare" incidents, but we had data from the solar flare measurements that showed a small deviation, the day after.

So yes, you can attack this way.

Cheers,
Magnus
