The readme.txt
file is a default text file included in WordPress installations. Its primary purpose is to provide essential information about the WordPress installation, including the version, credits, and a brief guide on installation and usage. This file is aptly named readme.txt
because it is designed to be a “read me first” document, ensuring that users and developers have access to vital details about the software.
In WordPress, the readme.txt
serves as a changelog, detailing updates and version history. This transparency helps users and developers understand improvements, bug fixes, or security patches included in the latest versions. The file also credits WordPress contributors, showcasing the open-source community’s collaboration.
While its primary role is informational, the readme.txt
file also helps developers identify the WordPress version quickly. This can be particularly useful when troubleshooting or ensuring compatibility with plugins and themes. The name and format ensure it is accessible to anyone using a text editor.
This file is not unique to WordPress; many software packages include a readme.txt
for similar purposes. However, in WordPress, it is more than a courtesy—it is a crucial tool for documentation. Unfortunately, its utility also makes it a target for malicious users.
In the context of website security, the readme.txt
file can inadvertently expose sensitive information. Hackers and bots often scan for it because it reveals the WordPress version. Knowing this, attackers can exploit vulnerabilities specific to that version.
Despite these risks, the readme.txt
file plays a foundational role in WordPress documentation and transparency. Its presence underscores the importance of balancing information accessibility with security.
Do You Need the readme.txt
File on Your Server?
Technically, the readme.txt
file is not required for your WordPress site to function. The core files, database, and PHP scripts are what drive the functionality of WordPress. Removing or protecting this file will not affect your website’s performance.
However, the file serves an administrative purpose. It is especially useful for developers and administrators when diagnosing issues, updating plugins, or checking compatibility. If you regularly maintain your site, having the file can simplify certain processes.
For general users, keeping the file on your server might not be necessary. Once you’ve reviewed its content or documented the version details elsewhere, it is safe to rename, move, or delete it without any impact on your website’s functionality.
Ultimately, whether to keep the readme.txt
file comes down to weighing its utility against the potential security risks. Many security-conscious site owners opt to delete or restrict access to the file to minimize exposure to attackers.
Why Hackers Target the readme.txt
File
Hackers and bots frequently attempt to access the readme.txt
file because it is a quick and easy way to identify a WordPress site’s version. Armed with this knowledge, they can tailor their attacks to exploit known vulnerabilities in that specific version.
Malicious bots automate scans for readme.txt
files across countless websites. These scans are often part of a larger strategy to identify and compromise outdated or poorly secured WordPress installations. By targeting known vulnerabilities, hackers can inject malicious scripts, steal data, or gain unauthorized access.
For advanced hackers, the file can also serve as a starting point for reconnaissance. Once they know the WordPress version, they can look for unpatched plugins or themes commonly associated with that version.
The default presence of the readme.txt
file on most WordPress installations makes it a predictable target. Site owners who overlook its security inadvertently leave a potential entry point for attackers.
Content and Protection of the readme.txt
File
The readme.txt
file typically contains information like the WordPress version, installation guidelines, a changelog, and credits to contributors. While this information is primarily benign, the version number is particularly sensitive as it can lead to targeted attacks.
To protect this file, you can use several strategies:
- Rename or Delete the File: This is the simplest approach to prevent unauthorized access.
- Restrict Access via .htaccess: Use server-side rules to block external access to the file.
- Use a Security Plugin: Many WordPress security plugins can automatically secure or hide sensitive files.
- Keep WordPress Updated: Regular updates minimize the risk of vulnerabilities associated with older versions.
- Monitor Access Logs: Check for repeated attempts to access the
readme.txt
file and block suspicious IPs.
