In our journey so far, we’ve dealt mostly with plain text files. Bandit Level 9 to 10 introduces a new type of challenge: extracting information from a binary file. These files are compiled for machines, not humans, and reading them with cat results in a mess of unreadable characters.

This level teaches us how to use the strings command, a specialized tool for finding and printing the sequences of readable text embedded within binary data. 🧐

In the last level, we learned to find files that were intentionally hidden from view. Now, in Bandit Level 4 to 5, the challenge is different. The password file isn’t hidden, but it’s lost in a crowd of other files that are unreadable to humans.

This level teaches us a critical skill: how to programmatically identify the type of data a file contains, allowing us to quickly find the needle in the haystack.
