All in I think the expenses were around $1200 total for the drone and this was like 8 years ago. Not something most would be willing to waste, but with time and effort you could make something now for probably a third the cost.
We also used a similar setup wired into a Jetski that we left attached to an adjacent dock once too. I can only imagine what others are doing ;D
Do your customers actually pay you to break security and then act on what is found? Or are most of them paying you to demonstrate that their security is perfect and then quietly burying results if they don't go that way?
I know DJI uses some communication method built on top of wifi but is it the type that is susceptible to standard wifi based attacks?
The main challenge is licensing, not technical siphistication. Most of the protocols in question are quite a bit less complex than wifi or Bluetooth.
There are tons of companies looking for simple check boxes, or affirmations. Tons that don't acknowledge their issues. I can say first hand that I had a project I was involved with that identified a substantial breach at a company under acquisition for an obscene amount of money. Most M&A seem to skip technical diligence beyond code review. Long story short there were actually three separate issues / actors within the network. They even had one authorized access by a competitor that a salesman had naively setup under the guise of a collaboration. They paid for the onsite investigation then realized that it was going to create a PR nightmare based on our findings. It would have been a huge exposure that would counter the obscene amount of marketing they were doing for the tech acquired. Their response was to not only ignore us (i'm assuming they eventually fixed things) but refuse to pay for the investigation performed and basically said.. we're a billion dollar company what are you going to do, sue us? We got stiffed with probably a quarter mill in work because they were right. Worst part is we called them to let them know originally because we found EXTREMELY sensitive source code and documentations of a crypto nature. Incidentally we saw some 0-days later on that leveraged undocumented functions that were curiously documented in our findings.
So yeah.. you see it all. That's why I love working with startups, make less, but they're appreciative and long term relationships are more worth it for us.
