Version: 0.5.0.67 beta
Github: https://github.com/marcocesarato/PHP-Antimalware-Scanner
Author: Marco Cesarato
This package, written in php, can scan PHP files and analyze your project for find malicious code inside it.
It provides a text terminal console interface to scan files in a given directory and find PHP code files the seem to contain malicious code.
The package can also scan the PHP files without outputting anything to the terminal console. In that case the results are stored in a log file.
This scanner can work on your own php projects and on a lot of others platform.
Use this command php -d disable_functions
for run the program without issues.
- php 5+

For test detection of malwares you can try detect they from this collection:
https://github.com/marcocesarato/PHP-Malware-Collection
You could find some false positive during scanning. For this you can choice the aggression level as following:
Param | Abbr | Aggressivity | Description |
---|---|---|---|
VERY AGGRESSIVE | Search for all functions/exploits on lists and all malware signatures without restrictions | ||
--agile |
-a | MEDIUM | Search for some specific exploits on lists with some restrictions and all malware signatures (on Wordpress and others platform could find more malware and more false positive) |
--only-signatures |
-s | NORMAL | Search for all malware signatures (could be perfect for Wordpress and others platform for have less false positive) |
--only-exploits |
-e | AGGRESSIVE | Search for exploits on lists |
--only-functions |
-f | MEDIUM | Search for all functions on lists (on some obfuscated code can't be detected) |
no params (default) (not recommended)
VERY AGGRESSIVE
--agile | -a (recommended)
MEDIUM AGGRESSION
--only-signatures | -s (recommended)
LESS AGGRESSIVE`
--only-exploits | -e
AGGRESSIVE
--only-functions | -f (not recommended)
MEDIUM AGGRESSION
Then if you run the scanner on a Wordpress project or others common platforms type --only-signatures
or --agile
as argument for a check with less false positive.
php -d disable_functions='' scanner -s
php -d disable_functions='' scanner -a
When a malware is detected you will have the following choices (except when scanner is in report scan mode --report
):
- Delete file
- Move to quarantine
(move to ./quarantine)
- Try remove evil code
- Try remove evil line code
- Open/Edit with vim
(need php -d disable_functions='')
- Open/Edit with nano
(need php -d disable_functions='')
- Add to whitelist
(add to ./scanner_whitelist.csv)
- Show source
- Ignore
Arguments:
<path> - Define the path to scan (default: current directory)
Flags:
-a --agile - Help to have less false positive on WordPress and others platforms
enabling exploits mode and removing some common exploit pattern
-f --only-functions - Check only functions and not the exploits
-e --only-exploits - Check only exploits and not the functions,
this is recommended for WordPress or others platforms
-s --only-signatures - Check only virus signatures (like exploit but more specific)
-h --help - Show the available flags and arguments
-l --log="" - Write a log file on 'scanner.log' or the specified filepath
-r --report - Report scan only mode without check and remove malware. It also write
a report with all malware paths found to 'scanner_infected.log'
-u --update - Update scanner to last version
-v --version - Get version number
--max-filesize="" - Set max filesize to scan (default: -1)
--exploits="" - Filter exploits
--functions="" - Define functions to search
--whitelist-only-path - Check on whitelist only file path and not line number
--list - Get default exploit and functions list
--list-exploits - Get default exploits list
--list-functions - Get default functions lists
Notes:
For open files with nano or vim run the scripts with "-d disable_functions=''"
Examples: php -d disable_functions='' scanner ./mywebsite/http/ -l -s --only-exploits
php -d disable_functions='' scanner -s --max-filesize="5MB"
php -d disable_functions='' scanner -s -logs="/user/marco/scanner.log"
php -d disable_functions='' scanner --agile --only-exploits
php -d disable_functions='' scanner --exploits="double_var2" --functions="eval, str_replace"
Usage: php scanner [--agile|-a] [--help|-h] [--log|-l] [--report|-r] [--version|-v] [--update|-u] [--only-signatures|-s] [--only-exploits|-e] [--only-functions|-f] [--list] [--list-exploits] [--list-functions] [--exploits <exploits>] [--functions <functions>] [--whitelist-only-path] [<path>]
