## PikesPeak
|
||
|
|
The main idea finding the flag using simple forensic techniques.
|
||
|
|
|
||
|
|
|
||
|
|
#### Step-1:
|
||
|
|
After we download `PikesPeak.jpg`, we try to open and see the flag and check if we find any.
|
||
|
|
|
||
|
|
<img src="PikesPeak.jpg">
|
||
|
|
|
||
|
|
#### Step-2:
|
||
|
|
I tried simple techniques and easily found answer when we send the command:
|
||
|
|
|
||
|
|
`strings PikesPeak.jpg | grep {`
|
||
|
|
|
||
|
|
I and got this as output:
|
||
|
|
|
||
|
|

```
|
||
|
|
|
||
|
|
#### Step-4:
|
||
|
|
|
||
|
|
I tried all the flags up there xP.
|
||
|
|
|
||
|
|
However one of them worked out.
|
||
|
|
|
||
|
|
#### Step-5:
|
||
|
|
Finally the flag becomes:
|
||
|
|
`CTFlearn{Gandalf}`
