Well, I guess I'll kick things off here with this unsolved Tor ARG. I found it a couple weeks ago and found very little about it. So far at least, it consists of two pages, and it seems to be focused on someone called Alice. http://pzagjfeoek2gyksj.onion/http://sophielkpqe34cl6.onion/
For the second page, the hex code at the start says:Sophie welcomes you.Patience is a virtue, especially in the Tor network. So is Perseverance as there are decoys. Sophie loves making things difficult for others '>Let's begin.Good luck.As for the binary, it's mostly unreadable.It says Ÿ§¾½ßýßÚÿ”ÎÞÿþì¼41;œÏþþ which is the same as Ÿ§¾½ßýßÚÿ”ÎÞÿþì¼ñœÏþ þAnother thing to note is at the bottom of the html of the page is this link:https://www.blackhatworld.com/members/sophie.36594/As for the first website I have no clue, although it seems unrelated.
The original binary corrected itself, here's a picture.
>>133the picture in the first website is related. If you put it into a hex editor and go to the end you get thisSophie is impressed.The key is: recital"Everything's static, nothing's dynamic here."
Here's the metadata from the Yin-Yang symbol.CameraZorki Zorki 4KGPS Position52.287000 degrees N, 104.305000 degrees EDate of Creation2018:01:01 00:00:00ArtistSophieCountryRussiaCityÐÑÐºÑÑÑÐºResolution200x200SourceÐÐ¾Ð¼Ð¸ÑÐµÌÑ Ð³Ð¾ÑÑÐ´Ð°ÌÑÑÑÐ²ÐµÐ½Ð½Ð¾Ð¹ Ð±ÐµÐ·Ð¾Ð¿Ð°ÌÑÐ½Ð¾ÑÑÐ¸ (ÐÐÐ)
Those coordinates point to the Russian city Irkutsk.
At this point I would consider this ARG closed because it doesn't seem like it's solvable just through the internet. I have a feeling there is something your supposed to see at those coordinates, but obviously nobody here would go there or be anywhere near there.
That is a real shame I wish I could go check it out
