We recently captured a spy. Our forensic team provided this file for further research. Find what is the plan. Note: Flag will be three words, separated by underscores.
From the story, we understand that this is a forensic challenge listed as OSINT.
So,let us dig a little deeper into it.
Prior to on the analysis, we need to tell Volatility what kind of memory image we are working with. The imageinfo plugin will scan the image and suggest several likely profiles.
In Volatility, we can see a lot of suggestions for the profile. The first one would be sufficient for analysis.
Then we need to check the running processes using the pslist plugin as shown in the image given below.
As you can see, there are a lot of open applications. And the interesting part is that Internet Explorer is found to be open. So let us check its search history.
Here we can see lots of results and the last one is a Pastebin URL.
And on browsing the Pastebin URL, we can see the page as shown below.
It looks like a Hint. So let’s move to the next stage by searching for any mention of the flag in the file given.
On having a closer look, we can see a file named
‘domectf.jpg’. So let us download and inspect the image using volatility3.
By this, we would receive an image of a ship which looks like as shown below.
As mentioned previously, the challenge is an OSINT.
So, let us start with getting more info about this image. On a closer inspection, we can derive the following information:
Name of ship: Veendam
The image was captured on: 05-09-2016
Let us try to find out where the ship was on that day.
From the search, we can find that the ship was in Halifax’s shipping port.
Now, let us search for Halifax shipping port in Google Street View & 360°. From this, we can confirm that the location is the port of Halifax, with the help of the glass building.
In Pastebin, we had seen the phrase “Your secret code will be beneath the foot of shipping magnate”.
Now, let us search for the shipping magnate of Halifax. From the search results, we can conclude that it is Sir Samuel Cunard. And there is a statue of him near the port.
On a closer look and remembering the note stated in the story, Flag will be three words, separated by underscores.
We can conclude that the flag is
