Hello Every One . Today I would like to talk about a Write Up in (INTERNETWACHE CTF 2016), that me and my friends was Playing as a Team (Hacku) in The last few Days , It was full of fun and cool Tasks, We Enjoyed a lot at IRC freenode.
The CTf was full of Tasks and were in a lot of Categories In :
- Misc
- Web
- Reversing
- Crypto
- Code
- Exploit
In This Article , I would like to share some of my solution of one of the Tasks with My resources that I used, and i spent a couple of Hours to solve it .
Al-thought it's have 90 Point(with high score), But It's very simple solution (I know That). At least it could help you or Give You a little Tips in another CTF .
So let's Go and have a Fun ...
The Title of The Task Says : BarParty (misc90)
The Description Says : Can you read the barcodes?
And Have the following Image Attached .
First , I Thought it's have Hidden Message , So I made some quickly steps to analyze the Image but found Nothing .
Then i thought to My self (Common it's Clearly Message says in a challenge way : Can you read the barcodes?)
So I made a decision To retrieve The BarCode and Opened The Photoshop and Started to cut The Barcode into Pieces .
I Separated First All Pieces with
Pen Tool .
Then in a new Window , i Transformed the pieces and tried to make it into pairs linked to each other like this .
Then I went to
www.onlinebarcodereader.com to read The Barcode Online and it's read to me with (
IW{Bar), this is the beginning of the Flag So i knew that am in the right Direction .
I returned back to Photoshop and Linked All the pieces Together and this is the final Image i Made .
Finally , I read all the pieces separately from onlinebarcodereader.com and got the flag :
IW{Bar_B4r_C0d3s}
