The Steemit Crypto Challenge #2 - Progression Update
Prepare - Uncover - Outwit - Find - WIN!
The second Steemit Crypto Challenge is running and is almost finished!
Here's a summary of what's going on so far .
The Steemit Crypto Challenge #2
The first hint was a morse code right under the Crypto Challenge logo.
The code says DROPBOX. User @andu came to the right conclusion that we need to log in to Dropbox.
With the email address from the first Crypto Challenge and hint number 2
B EHOX LTBEBGZ which is a Caesar-shift and decoded says: i love sailing, the Crypto Task Force around @andu successfully logged in to Dropbox.
In this Dropbox account three files waited for our puzzle solvers. An Image, an audio and a password protected .rar file.
The goal was to find out the location of the following picture:
User @dercoco was able to decode the audio file. The audio was recorded in reverse and was distorted.
He took the whole even further and found the right location! Hats off, still don't know how our friend managed to do it so fast. You might tell us?
The name of the location was needed in order to open the .rar file.
Inside this .rar file was a text message with the following:
You came so far. I am amazed by your skills my friend. But you came to an dead end. IÇínÜ«ÍàThe Crypto Task Force is stuck at this point. They solved the code here and found out that IÇínÜ«Íà encoded is BlockchainJ
Huge lol for this comment:
Since I at first wanted to make a post about it, but then didn't have time for that, I will now write about it here:
I first looked at the metadata, just to see if it was as easy as looking up the gps data, but no gps data was saved in the picture.
Then I did a little bit of stalking (sorry for that... you take nice pictures btw maybe you're also interested in my photos? :) and I found out that he indeed lives in Hamburg. After quite a bit of random searching, I started to look for a bus stop with a pretty long name, since that's a piece of information he didn't blur out. That didn't really help, so I used the timestamp of the metadata and the rays of the sun in the picture to determine in which direction he was facing. He was facing north. That still didn't really help, so I used the information of the audio message. He said he was near a building that said "studio". With all those informations, it actually went pretty smooth.
I searched for "studio Hamburg" in google maps. There are many studios, so I looked at studios that were near intersections with a bus stop with a long name just on the road heading north of the intersection. At the second pick I had already found it :)
I'm really astounded by how you can really find out private infos like that by just using different pieces of information. Of course this was meant to be uncovered, but now I know that if you really want to, you can find out so many things about different people that way.
