Challenge Prompt

After logging in, you will find multiple file parts in your home directory. These parts need to be combined and extracted to reveal the flag.

Problem Type

• Zip File

Solve

We are told we need to SSH into the machine, so we start with that.

Check the folder and see we have instructions.txt and part_aa through part_ae.

The instructions:

• The flag is split into multiple parts as a zipped file.
• Use Linux commands to combine the parts into one file.
• The zip file is password protected. Use this “supersecret” password to extract the zip file.
• After unzipping, check the extracted text file for the flag.

So, let’s combine all the files together into part_aa by appending them to the end in order.

Then we can rename the file to flag.zip.

Then unzip the file, using supersecret as the password:

And finally open the file to get the flag!
