Hacking 101: Black Hat vs. White Hat vs. Gray Hat Hacking - Splunk

: Instead of trying to "crack" a password, the attacker crafts a ZIP where the filenames contain directory traversal sequences (e.g., ../../../../var/www/shell.php ).

If the challenge involves uploading the ZIP to a server, the most aggressive approach is .

: A key Black Hat technique is sending malformed files to see how the application's parser reacts. For a ZIP, this means testing how different tools (WinRAR, 7-Zip, or a web parser) see the same archive.

Below is a write-up for a Black Hat-inspired approach to resolving a ZIP-based challenge. 1. Reconnaissance: Mapping the Surface

Before touching any tools, a Black Hat mindset starts with identifying what the system "believes" about the file.

: When the server unzips the archive, it inadvertently overwrites a critical system file or place a web shell in a reachable directory, giving the attacker full control over the machine. 3. Brute Force & Known Plaintext
