Had a lot of fun tearing apart this projector to hack it, unfortunately wasn't able to test the exploit at the end of the day due to some hard lessons I learned!

Thanks for pointing that out! I'll try to update my phrasing to make it more clear. At the end of the day, I don't have definitive proof of anything, however, I'm fairly confident that it was taken down in response to one of two things: a) the payload was downloaded and executed (technically), or b) I was badgering their domain with requests to re-download it.
If it was a), then this might indicate a more advanced adversary who has the TTPs to support this. If it was b), which hints at something more reactionary, then I'm going to guess the adversary was slightly less advanced.
Lmk if you have more questions!

Yeah, when I decoded the B64 params, I did see the `cid` keyword, and briefly thought that this might be just really good adware. However, the following stages were too sophisticated for some person to just serve me an ad.
And I'm not sure if a coffee shop farther outside of Tyson's (not going to ask why you specifically said that area) would've helped. I'm very confident that they tore down their C2 after seeing either a (in their eyes) successful callback, or me badger their server with follow on requests.

> Also, please don't execute payloads on your laptop. That seems really stupid.
I would never execute a payload that I didn't manually vet on my computer :) That's why I didn't actually execute the full stage-two, but just pieces of it so it would decode what it was reaching out to. I also replaced the `eval` in the next stage to an `echo` to see what it was doing!

Small blog post where I detail a malicious update I got served, try to track what it was doing, who sent it, and my mistakes. Would love to hear your thoughts!
