#3

but never mind…any nudges appreciated… for me too … (as soon as this challenge has been published)… … … :wink:

#4

Am I missing something obvious? The only thing I see that could be dug into is a parked domain.
E: Got very basic leads, but not sure what’s in scope…

#5

Tried tracing the domain’s IP but coordinates wouldn’t work…

#6

I have tried like 3 or 4 different coordinates from various ways, nothing works…

#7

Currently stuck…
Tried the GPS coordinates (in DMS format) for city in europe and the building (not in europe) for the big event the leader tweeted about… Anyone got a nudge if I’m barking up the wrong tree or if I’m getting closer?

#8

Done with one hint. Hardest part for me is calulating correct DMS format.
At first i tough: whois creating that strange challenges?
Then i sang a song with bird and cat :wink:

As always we can bruteforce that challenge with two nested for’s loop from 0 to 90 with 0.000001 step. Its only 90 000 000 * 90 000 000 attempts. Easy :wink:

#9

Owned, thanks to @Kucharskov for keeping me in the right direction

#10

Got it. Thanks @clubby789

#11

I found the position but when i get “Sattelite is repositioning…”
Is this a bug or the challenge is not over yet lol ?

The website is basically a wrapper for AES decryption, using your coords as the key. That error means that there was an error during decryption. Your coords/format is wrong

#13

i guess challenge got broken.
pm’ed author

#14

Found some interesting

!WHOIS records
but got stuck after that. The coords linked to those weren’t correct so I must be barking up the wrong tree. Time to try harder.

#15

Done.
But now its challenge dont work how it must do.
We can’t finish this challenge without help now.
If you need help pm me.

#16

Yeah, the challenge looks broken now for the first step. I solved it a few days ago but when trying to help someone just now, I saw the information has changed now and I don’t think one can get past the first step without help. Needs to be fixed.

#17

The first step is indeed broken, send me a PM if you need help.

#18

Finally got this… thanks to @roaldnefs for the first hint(which is now gone) and the nudge

#19

Any updates? is it still broken?

#20

Done.
Thank you @roaldnefs for sending me the right information after it got broken.
That was really fun.

#21

After PM’ing @roaldnefs, I believe I was already past the “broken” part and got the required info. Now I just need to dig deeper for more information I guess. Will update if I manage to get further or solve the challenge.

For now my tips would be:
don’t rely on WHOIS, as that got changed.
remember it’s an OSINT challenge.

#22

Got it, only thing I would say is follow the handle :slight_smile: First step is fixed.
