Gallery - wej ynit
i have an old damaged disk , it contains a lot of my images , i use it as a gallery actually , in it , i had a secret can you get it back for me ?
1. The file that was attached was .E01 disk image I opened the disk image using Autopsy and extracted everything i thought looked interesting (2 txt files and bunch of images)
2. One of the two txt files was called 121-steghide.txt, alluding that steghide was used to hide the message and second was called 123-Garbage.txt which looked like random strings, yet i thought could be useful later on.
3. Using steghide info <filename> to check every JPG image for possible hidden message, excluding PNG since steghide works only on JPG, BMP, WAV and AU
4. Only JPG image that reacted to steghide info was called 95-WallpaperHD19756487Ef4.jpg and asked for password which I didn't have
5. After searching for password in autopsy, i thought 123-Garbage.txt had a purpose and for some reason every string inside it was same length.
6. I used 123-Garbage.txt now as a wordlist for a password bruteforcing a way in, leaving me a text file 95-WallpaperHD19756487Ef4.jpg.out containing message that was hidden int the image - “the flag”
sh*tty ransomware - Oceans
A write up regarding the Forensics challenge Shtty Ransomware
So the challenge tells us about a peice of malware that infected someones computer
disguised as a game and we're asked to find the IP and PORT number associated with it
To begin we start off by downloading a file called
A simple strings search of the file shows a ton of info regarding a windows machine
Lets trying running Volatility on it to see if we're playing with a Dump file.
python vol.py -f ShittyRansomware.raw imageinfo
Sure enough! Now we can extract some data
Now lets look at web history of this user
I'm using the plugin - Chromehistory from 'superponible'
python vol.py -f ShittyRansomware.raw --profile=Win7SP1x64 chromehistory
Here we can see 2 interesting links
Google Drive - Pro Evolution Soccer Pastebins - pro10 light version
If we take a look at the pastebins file we see some interesting info
A link to the game and a password for the file
After downloading and extracting the files we now have the malware executable
Now we need to see where its pointing...
Lets load up wireshark and capture the packets while running the malware.
We can see an HTTP GET request was made
If we follow the HTTP stream we can now see the IP and PORT the malware was trying to contact
Now if we follow the IP and PORT
It will return the flag
