Safe Headers Scanner helps WordPress administrators identify common issues that may cause header-related problems. 
The plugin scans installed themes and plugins for: 
* Unnecessary whitespace before <code><?php</code> tags 
* Extra whitespace after closing <code>?></code> tags 
* Direct output (e.g., <code>echo</code>, <code>print</code>) before headers are sent
Results are displayed in a clear report, so you can review and fix potential issues easily.

Safe Headers Scanner

Scan themes and plugins for potential header issues such as whitespace before/after PHP tags or direct output before headers.

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.

<h3>Interpreting the Results</h3>
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 <a href="https://wordpress.org/support/" rel="ugc">Support Forums</a>, 
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 <code>wp-config.php</code> file; 
listing extra admin accounts; or finding content in posts which you did not put there.
Understanding the three different result levels:
<ul>
<li>Severe: results that are often strong indicators of a hack (though they are not definitive proof)</li>
<li>Warning: these results are more commonly found in innocent circumstances than Severe matches, but they should still be treated with caution</li>
<li>Note: lowest priority, showing results that are very commonly used in legitimate code or notifications about events such as skipped files</li>
</ul>
<h3>Help! I think I have been hacked!</h3>
Follow the guides from the Codex:
<ul>
<li><a href="https://codex.wordpress.org/FAQ_My_site_was_hacked" rel="nofollow ugc">Codex: FAQ – My site was hacked</a></li>
<li><a href="https://codex.wordpress.org/Hardening_WordPress" rel="nofollow ugc">Codex: Hardening WordPress</a></li>
</ul>
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.
<h3>Updates</h3>
Updates to the plugin will be posted here, to <a href="http://ocaoimh.ie/" rel="nofollow ugc">Holy Shmoly!</a> and the <a href="http://ocaoimh.ie/exploit-scanner/" rel="nofollow ugc">WordPress Exploit Scanner</a> page will always link to the newest version.
<h3>Other Languages</h3>
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:
<ul>
<li><a href="http://wpbiz.jp/files/exploit-scanner-hashes/ja/" rel="nofollow ugc">Japanese</a> – thanks to Naoko</li>
<li><a href="http://talkpress.de/artikel/exploit-scanner-hash-deutsch-wordpress" rel="nofollow ugc">German</a> – thanks to Robert Wetzlmayr</li>
</ul>
The hash files should only be declaring an array called $filehashes and the majority of the hashes should still be the same.

Exploit Scanner

Works very well by pointing suspicious elements.

Useful and effective

Great plugin, but it's not well documented.

Anyways, it works on version 4.8.3 and theoretically any version as long as you generate (if you don't have) the hashes for your wordpress version; in my case I had to generate for 4.8.3 and it did a good job :)

Great security scan plugin but..

830 matches in a clean installation

Search the files and database of your WordPress install for signs that may indicate that it has fallen victim to malicious hackers.
