Description

PHP Antimalware Scanner is a free tool to scan PHP files and analyze your project to find any malicious code inside it.

It provides an interactive text terminal console interface to scan a file, or all files in a given directory (file paths can also be managed using --filter-paths or --ignore-paths), and find PHP code files that seem to contain malicious code. When a probable malware is detected, will be asked what action to take (like add to the whitelist, delete files, try clean infected code, etc).

The package can also scan the PHP files in a report mode (--report|-r), so without interacting and outputting anything to the terminal console. In that case, the results will be stored in a report file in HTML (default) or text format (--report-format <format>).

This scanner can work on your own php projects and on a lot of other platforms using the right combination of configurations (ex. using --lite|-l flag can help to find less false positivity).

⚠️ Remember that you will be solely responsible for any damage to your computer system or loss of data that results from such activities. You are solely responsible for adequate protection and backup of the data before executing the scanner.

📖 Install

Release

You can use one of these methods to install the scanner by downloading it from GitHub or directly from the console.

Download

Go to the GitHub page and press on the Releases tab or download the raw file from:

Console

1. Run this command from the console (the scanner will be downloaded to your current directory):

   wget https://raw.githubusercontent.com/marcocesarato/PHP-Antimalware-Scanner/master/dist/scanner

2. Run the scanner:

   php scanner ./dir-to-scan -l ...

3. (Optional) Install as bin command (Unix Bash)

   Run this command:

   wget https://raw.githubusercontent.com/marcocesarato/PHP-Antimalware-Scanner/master/dist/scanner -O /usr/bin/awscan.phar && \
   printf "#!/bin/bash\nphp /usr/bin/awscan.phar \$@" > /usr/bin/awscan && \
   chmod u+x,g+x /usr/bin/awscan.phar && \
   chmod u+x,g+x /usr/bin/awscan && \
   export PATH=$PATH":/usr/bin"

   Now you can run the scanner simply with this command: awscan ./dir-to-scan -l...

🔎 Scanning mode

The first think you need to decide is the strength, you need to calibrate your scan to find less false positive as possible during scanning without miss for real malware. For this you can choose the aggression level.

The scanner permit to have some predefined modes:

Mode	Alias	🚀	Description
None (default)		🔴	Search for all functions, exploits and malware signs without any restrictions
Only exploits	-e	🟠	Search only for exploits definitions Use flag: --only-exploits
Lite mode	-l	🟡	Search for exploits with some restrictions and malware signs (on Wordpress and others platform could detect less false positivity) Use flag: --lite
Only functions	-f	🟡	Search only for functions (on some obfuscated code functions couldn't be detected) Use flag: --only-functions
Only signatures	-s	🟢	Search only for malware signatures (could be a good solution for Wordpress and others platform to detect less false positivity) Use flag: --only-signatures

💻 Usage

Command line

php amwscan ./mywebsite/http/ -l -s --only-exploits
php amwscan -s --max-filesize="5MB"
php amwscan -s -logs="/user/marco/scanner.log"
php amwscan --lite --only-exploits
php amwscan --exploits="double_var2" --functions="eval, str_replace"
php amwscan --ignore-paths="/my/path/*.log,/my/path/*/cache/*"

Doesn't work?

In case above command doesn't work, you can use script responsible for malware scan manually by executing: php dist/scanner <path>

To check all options check the Documentation

Suggestions

If you are running the scanner on a Wordpress project or other popular platform use --only-signatures or --lite flag to have check with less false positive but this could miss some dangerous exploits like nano.

Programmatically

On programmatically silent mode and auto skip are automatically enabled.

use AMWScan\Scanner;

$app = new Scanner();
$report = $app->setPathScan("my/path/to/scan")
              ->enableBackups()
              ->setPathBackups("/my/path/backups")
              ->enableLiteMode()
              ->setAutoClean()
              ->run();
