The document discusses securing WordPress sites from three perspectives: a user, system administrator, and developer. For users, it recommends choosing trusted plugins/themes, keeping everything updated, backups, strong passwords, and security plugins. For administrators, it recommends server configuration hardening like HTTPS, limiting permissions. For developers, it stresses sanitization, validation, escaping and secure coding practices. Responsible vulnerability disclosure is also covered.
Presentation on WordPress security, which looks at why WordPress sites get hacked, how they get hacked, what to do to reduce your risk and how to recover your site after it has been hacked, or infected with malware.
A penetration testing report submitted during internship at ICT Academy, IIT Kanpur. This report contains a basic flow how to perform penetration testing, from reconnaissance to finding vulnerability. This should be helpful for security researchers who are looking to write a penetration testing for their project.

Bilgi sistemlerine yönelik veya bilgi sistemleri kullanılarak işlenen suçlar ve gerçekleştirilen saldırılar bu sistemler üzerinde izler bırakmaktadır. Ayrıca sistem hafızalarında ve ağ üzerinde söz konusu aktivitelere ilişkin canlı analiz ile işlenen suçların izleri gözlenebilmektedir.
Bilgi sistemleri üzerindeki kalıcı ve geçici suç izlerinin elde edilmesi ve analizi için çoğunlukla ticari adli bilişim çözümlerinin kullanılması gerekmektedir. Bunun sebebi incelenecek verilerin çokluğu ve bu büyüklükteki verilerin manuel yöntemlerle makul bir zaman aralığında incelenememesidir.
Ticari çözümler kullanım kolaylığı sağlayabilmek için pek çok teknik detayı kullanıcılardan gizlemektedirler. Ancak kullanıcıların temel teknik bilgilere sahip olmaması uzmanlıklarının sınırlanmasına ve olası problemlere karşı etkili çözümler geliştirememelerine yol açmaktadır.

WordPress started out as a blogging platform.
It is now a Content Management System
and an Application Framework
with a full REST API.
6. What is WordPress?
Blog - shawnhooper.ca
Twitter - @shawnhooper
WordPress (the software) should not be confused
with WordPress.com, a WordPress web hosting
service run by Automattic.
Automattic was founded by WordPress
co-founder Matt Mullenweg.
The open source project can be found at
WordPress.org
7. What is WordPress?
Blog - shawnhooper.ca
Twitter - @shawnhooper
WordPress is developed primarily in PHP
Although JavaScript is becoming a larger part of
the front-end codebase with every release.
It’s database is a MySQL relational database.
8. Extensibility
Blog - shawnhooper.ca
Twitter - @shawnhooper
WordPress’ real power is in its extensibility. It’s API
allows for the development of third party themes
and plugins.
5,389 Themes
54,218 Plugins
* Only in the free repo. (Feb 2018)

13. So What Can We Do ?
Blog - shawnhooper.ca
Twitter - @shawnhooper
Let’s look at how to secure WordPress as:
A User
A System/Server Administrator
A Developer
An Information Security Professional
15. Choose Wisely
Blog - shawnhooper.ca
Twitter - @shawnhooper
The largest source of problems in WordPress
Security come from the Plugin Ecosystem.
Choose your themes & plugins wisely!
16. Choose Wisely
Blog - shawnhooper.ca
Twitter - @shawnhooper
Are they regularly maintained?
Does the author(s) respond to support questions
promptly?
Are they popular?
17.
18. Keep It Updated!

23. Admin Login
Blog - shawnhooper.ca
Twitter - @shawnhooper
Older versions of WordPress came with an
“admin” login by default.
This became a default target for attacks. Use a
different username.
26. Use Email As Login
Blog - shawnhooper.ca
Twitter - @shawnhooper
WordPress defaults to a username login
Usernames are fairly discoverable in WordPress
The Email Login plugin forces login using an
email address instead.
https://wordpress.org/plugins/wp-email-login/
27. Least Privilege
Blog - shawnhooper.ca
Twitter - @shawnhooper
Only gives users the permissions they need to do
their jobs.
Subscriber - Can Read
Contributor - Can Write, but not publish
Author - Can Publish their own Posts
Editor - Can Publish Anyone’s Posts & Pages
Administrator - Can modify site configuration
31. Server Configuration
Blog - shawnhooper.ca
Twitter - @shawnhooper
Some of these recommendations can be done by
users too. But they’re not things you do IN
WordPress.
32. Enable HTTPS
Blog - shawnhooper.ca
Twitter - @shawnhooper
There’s no reason these days for your website not
to be secured by SSL. LetsEncrypt offers free
certificates, and many web hosts have this as a
one-click install option.
33. Enable SFTP
Blog - shawnhooper.ca
Twitter - @shawnhooper
Secure File Transfer Protocol (SFTP) is FTP over
SSH.
If you’re going to give users FTP access to their
sites, this is the best way to do it.
38. Disable XML-RPC
Blog - shawnhooper.ca
Twitter - @shawnhooper
There are also plugins to do this,
but doing so at the server side is recommended.
39. Keep Sites Isolated
Blog - shawnhooper.ca
Twitter - @shawnhooper
If you’re running multiple sites on the same server,
keep them in separate home directories
running as separate users
This helps prevent cross-contamination of sites
in the event of a hack.
40. Checksum Validation
Blog - shawnhooper.ca
Twitter - @shawnhooper
Using WP-CLI, see if files have been modified:
wp core verify-checksums
wp plugin verify-checksums --all
43. Sanitization & Validation
Blog - shawnhooper.ca
Twitter - @shawnhooper
There are a pile of functions to do input sanitization:
sanitize_title()
sanitize_user()
balance_tags()
tag_escape()
is_email()
sanitize_html_class()
array_map()
sanitize_email()
sanitize_file_name()
sanitize_term()
sanitize_term_field()
sanitize_html_class()
sanitize_key()
sanitize_mime_type()
sanitize_option()
sanitize_sql_orderby()
sanitize_text_field()
sanitize_title_for_query()
sanitize_title_with_dashes()
sanitize_user()
sanitize_meta()
44. Validation
Blog - shawnhooper.ca
Twitter - @shawnhooper
Are values of the correct type? Do they have the expected
values?
$quantity = intval( $_POST[‘quantity’] );
or
$quantity = absint( $_POST[‘quantity’] );
if ( $quantity > 10 ) {
die(‘Quantity Out of Range’);
}
46. Escaping Text
Blog - shawnhooper.ca
Twitter - @shawnhooper
esc_attr( $text );
esc_attr__( $text, $domain );
Escaping a string for use in an HTML attribute tag.
<div data-value=“<?php echo esc_attr( $value ); ?>”>
48. Escaping HTML
Blog - shawnhooper.ca
Twitter - @shawnhooper
wp_rel_nofollow( $html );
Adds rel=“nofollow” to every link in the HTML fragment.
49. Sanitization & Escaping
Blog - shawnhooper.ca
Twitter - @shawnhooper

50. Working with the Database
Blog - shawnhooper.ca
Twitter - @shawnhooper
Use $wpdb
51. Working with the Database
Blog - shawnhooper.ca
Twitter - @shawnhooper
$wpdb->insert(
‘table_name’,
array(
'column1' => 'value1',
'column2' => 123
),
array(
'%s',
'%d'
)
);
52. Working with the Database
Blog - shawnhooper.ca
Twitter - @shawnhooper
$wpdb->update(
'table',
array(
'column1' => 'value1', 'column2' => 'value2'
),
array( 'ID' => 1 ),
array(
'%s', // value1
'%d' // value2
),
array( '%d' )
);
53. Working with the Database
Blog - shawnhooper.ca
Twitter - @shawnhooper
Custom Queries should be written using the $wpdb->prepare() function.
$safeSQL = $wpdb->prepare(“SELECT * FROM {$wpdb->prefix}tablename WHERE col1 = ‘%s’AND col2 = %d”, $sParam, $iParam);
$wpdb->query($safeSQL);
54. WordPress Coding
Standards
Blog - shawnhooper.ca
Twitter - @shawnhooper
WordPress has documented coding standards that apply to its PHP,
JavaScript, HTML, CSS and Accessibility components.
Although on it’s own this doesn’t necessarily improve security, it will
make code more readable, and more testable, which minimizes the
chance for errors!
https://codex.wordpress.org/WordPress_Coding_Standards
56. Responsible Disclosure
Blog - shawnhooper.ca
Twitter - @shawnhooper
Don’t bring more attention to security vulnerabilities in public
forums, blog posts, chats, or issue trackers without giving
developers a reasonable chance to patch it first.
