Description

We've received reports that Draeger has stashed a huge arsenal in the pocket dimension Flaggle Alpha. You've managed to smuggle a discarded access terminal to the Widely Inflated Dimension Editor from his headquarters, but the entry for the dimension has been encrypted. Can you make it inside and take control?

Solution Approach

Core idea: Identify the weakness from source review or fingerprinting first. Iterate with incremental payloads instead of guessing.

Steps

1. First, unzip the .zip file given and jump to the extracted directory.

2. Now run the binary file.

3. Hm.. let us enter any number here (?)

4. The program prompted us to enter the decryption key.

5. Let us decompile the file using ghidra.

6. Let us check the menu() function.

7. Got the thing we are looking for there.

The decryption key -> sup3rs3cr3tw1d3

1. Enter the key.

2. Got the flag!

Lessons Learned

1. Identify the weakness from source review or fingerprinting first.
2. Iterate with incremental payloads instead of guessing.
3. Reuse the same pattern in future engagements.
