Detect potentially malicious PHP files.

What does it detect?

PHP-malware-finder does its very best to detect obfuscated/dodgy code as well as files using PHP functions often used in malwares/webshells.

The following list of encoders/obfuscators/webshells are also detected:

• Best PHP Obfuscator
• Carbylamine
• Cipher Design
• Cyklodev
• Joes Web Tools Obfuscator
• Php Obfuscator Encode
• SpinObf
• Weevely3
• atomiku
• cobra obfuscator
• phpencode
• webtoolsvn

How does it work?

Detection is performed by crawling the filesystem and testing files against a set of YARA rules. Yes, it's that simple!

How to use it?

$ ./phpmalwarefinder -h
Usage phpmalwarefinder [-cfhw] <file|folder> ...
	-c  Optional path to a configuration file
	-f  Fast mode
	-h  Show this help message
	-v  Verbose mode

Or if you prefer to use yara:

$ yara -r ./malwares.yara /var/www

Whitelisting

Check the whitelist.yara file. If you're lazy, you can generate whitelists for entire folders with the generate_whitelist.py script.
