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 be 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 whitelist, delete files, try
clean infected code etc…).
The package can also scan the PHP files in a report mode (--report|-r), so without interact 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 others platform using the right combinations 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 to adequate protection and backup of the data before execute
the scanner.

    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.<br /> For this you can choose the aggression level.<br /> The scanner permit to have some predefined modes:

  <p>
    Mode<br /> Alias<br /> 🚀<br /> Description
  </p>
  
  <p>
    None (default)
  </p>
  
  <p>
    🔴<br /> Search for all functions, exploits and malware signs without any restrictions
  </p>
  
  <p>
    Only exploits<br /> <code>-e</code><br /> 🟠<br /> Search only for exploits definitionsUse flag: <code>--only-exploits</code>
  </p>
  
  <p>
    Lite mode<br /> <code>-l</code><br /> 🟡<br /> Search for exploits with some restrictions and malware signs (on WordPress and others platform could detect less false positivity)Use flag: <code>--lite</code>
  </p>
  
  <p>
    Only functions<br /> <code>-f</code><br /> 🟡<br /> Search only for functions (on some obfuscated code functions couldn&#8217;t be detected) Use flag: <code>--only-functions</code>
  </p>
  
  <p>
    Only signatures<br /> <code>-s</code><br /> 🟢<br /> Search only for malware signatures (could be a good solution for WordPress and others platform to detect less false positivity)Use flag: <code>--only-signatures</code>

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