Hello,

I noticed that the utils folder is present in the repository, containing files such as ip.yar, url.yar, magic.yar and suspicious_strings.yar, but it is currently missing from the Categories section in the README.md.

After analysing the contents, I have drafted a description to fill this gap, maintaining the existing style of the documentation.

Changes:

• Added a new Utils section to README.md.
• The description follows the existing style and summarises the utility of these rules as building blocks for broader analysis.

Proposed text:

Utils

In this section you will find Yara rules specialised toward the identification of common data patterns and generic forensic indicators. These rules serve as building blocks to detect network identifiers, file structures, or suspicious artifacts useful for broader analysis.

I hope this contribution helps improve the project's documentation.
