By Rizzykun

Category: OSINT

Description:

One of our agents managed to locate one of the suspects. We lost contact before he could tell us where he was. This snapshot was the only documentation he could send. Can you find where this place is?

Note: Use the google map name if you have found the location.

Flag format: SIBER25{main_street-town_name-state_name-country}

Answer:

Resource:

So, this is the last place the suspect was seen, okay , Let’s lock in!!

First, we need to identify where is this place, maybe the shops could help?

So, he is near these shops. Let’s try locating every single store.

When googling each of the store names, almost every single one returns that it is a part of multiple branches of a store chain in Russia except for Клубника, салон фотопечати (Strawberry, Photo Printing Salon). This store is an independent and unique store, then, I find a city website named chaykovsky which holds info about the store.

The website pinpoint the exact location of the store and give the address. Then, I enter the address in google Maps and it gave the result:

Then, we get the address , following the flag format we got :

SIBER25{ulitsa_sovetskaya-chaykovsky-perm_krai-russia}

The suspect was last seen located near mall named ТЦ (Мега).

Answer :

Given an image file and .txt file. I immediately opened the image file using Exterro FTK Imager.

As I was traversing through the image file, I found multiple image files in the recycle bin. When I click it to read as ASCII, I get the flag :

Answer :

Just like the Dumpster challenge, I quickly open the image file given using Exterro FTK Imager.

I found out there were multiple interesting file directories, and when for looking.

In the explorer folder, I noticed there are multiple deleted files. So I try to export them to my laptop and try to see it using tools named Thumb cache viewer.

I check every single file and I see the flag in an image. Then I merged all the info from all the images and got the flag.

Flag = SIBER25{V3RY_sMA1L_thUm8n411S}
