Posted on Oct 21 Greetings, As we step into Level 12 of the Bandit wargame, we're faced with a unique challenge involving data manipulation and repeated compression. Get ready to roll up your sleeves and dive into the intricate world of Command-line operations.Before we embark on our journey, make sure you've successfully acquired the password for the previous level: JVNBBFSmZwKKOP0XbFXOoW8chDz5yVRv.Creating a Workspace: Begin by creating a temporary directory named /tmp/hexdump. Navigate to this new directory using the following commands:This step ensures you have a clean workspace to carry out the tasks.Preparing the Data: Now, let's grab the data.txt file from the previous level and place it into your temporary directory:This sets the stage for our data manipulation journey.Decoding Hexdump: We'll start by converting the hexdump back to its original form. Execute the following commands to perform this transformation:The xxd -r command reverses the hexdump, reconstructing the original data. The file command is used to inspect the type of data in the hex file.Compressing and Decompressing: In the next steps, we'll play with compression. These commands help us understand the data and its transformations:Here, we rename hex to hex.gz, then unzip it using gunzip. The file command confirms the type of data.Further Compression: Our exploration continues with more compression:We rename hex to hex.bz2 and use bunzip2 to decompress it. Once again, the file command provides insight into the data's nature.Final Steps: The puzzle nears its completion. Execute these commands to perform more decompression given the working file’s data type:These commands navigate through decompression, untar, and finally, reveal the contents of data8.bin which is the password for the next level:Templates let you quickly answer FAQs or store snippets for re-use.
