Exploit Scanner Plugin

This plugin searches the files on your website, and the posts and comments tables of your database for anything suspicious. It also examines your list of active plugins for unusual filenames.

It does not remove anything. That is left to the user to do.

Interpreting the Results

It is likely that this scanner will find false positives (i.e. files which do not contain malicious code). However, it is best to err
on the side of caution; if you are unsure then ask in the Support Forums,
download a fresh copy of a plugin, search the Internet for similar situations, et cetera. You should be most concerned if the scanner is:
making matches around unknown external links; finding base64 encoded text in modified core files or the wp-config.php file;
listing extra admin accounts; or finding content in posts which you did not put there.

Understanding the three different result levels:

• Severe: results that are often strong indicators of a hack (though they are not definitive proof)
• Warning: these results are more commonly found in innocent circumstances than Severe matches, but they should still be treated with caution
• Note: lowest priority, showing results that are very commonly used in legitimate code or notifications about events such as skipped files

Help! I think I have been hacked!

Follow the guides from the Codex:

• Codex: FAQ – My site was hacked
• Codex: Hardening WordPress

Ensure that you change all of your WordPress related passwords (site, FTP, MySQL, etc.). A regular backup routine
(either manual or plugin powered) is extremely useful; if you ever find that your site has been hacked you can easily restore your site from
a clean backup and fresh set of files and, of course, use a new set of passwords.

Updates

Updates to the plugin will be posted here, to Holy Shmoly! and the WordPress Exploit Scanner page will always link to the newest version.

Other Languages

Unfortunately for people using WordPress versions for other locales some of the file hashes may be incorrect as some strings have to be hardcoded in their translated form. Here are some file hashes for WordPress in other languagues provided separately by other members of the community:

• Japanese – thanks to Naoko
• German – thanks to Robert Wetzlmayr

The hash files should only be declaring an array called $filehashes and the majority of the hashes should still be the same.

1. Download and unzip the plugin.
2. Copy the exploit-scanner directory into your plugins folder.
3. Visit your Plugins page and activate the plugin.
4. A new menu item called “Exploit Scanner” will be available under the Tools menu.

Installation Instructions

1. Download and unzip the plugin.
2. Copy the exploit-scanner directory into your plugins folder.
3. Visit your Plugins page and activate the plugin.
4. A new menu item called “Exploit Scanner” will be available under the Tools menu.

How do I fix the out of memory error?

Scanning your website can take quite a bit of memory. The plugin tries to allocate 128MB but sometimes that’s not enough. You can modify the amount of memory PHP has access to from within the plugin admin page. You can also limit the max size of scanned files. Reduce this number to skip more files but be aware that it may miss hacked files. Any skipped files are listed after scanning. Memory is also used if you have deep directories because of the way the scanner works. It will help if you clean out any cache directories (wp-content/cache/ for example) before scanning.
