As we embark on our journey to uncover the hidden CMS beneath the surface of a website, one of the most fundamental techniques at our disposal is manual inspection. 

By rolling up our sleeves and delving into the website’s source code, we can uncover subtle clues that point us toward the Content Management System (CMS) in use. Here is how to properly use manual inspection:

Analysing HTML and JavaScript Code

The HTML and JavaScript code constituting a website contains valuable information about its underlying CMS. Different CMS platforms often leave distinct fingerprints in their code, resulting from how they structure and render content. Look for patterns like:

Class and ID Names: CMS platforms often generate unique element class and ID names. These names might be indicative of the CMS in use.

File Paths: Observe the file paths for style sheets, scripts, and other assets. Some CMSs have specific folder structures that can provide valuable insights.

Checking URLs for Known CMS Structures

CMS platforms often have characteristic URL structures for crucial components. For example:

WordPress: Look for “/wp-admin” or “/wp-content” in URLs.

Joomla: URLs may include “/administrator” or “/components.”

These URLs give hints about the CMS behind the scenes.

Identifying Comments and Meta Tags

Sometimes, CMS-specific information can be found within comments or meta tags in the source code. Developers might leave annotations or metadata that inadvertently reveal the CMS. Keep an eye out for:

Meta Generator Tags: Some CMSs insert meta tags indicating the version of the CMS used to build the website.

Comments: Developers may leave comments that refer to the CMS, especially in template files.

2. Online CMS Detection Tools

Online CMS identification tools from modern technology help us in our quest to identify a website’s Content Management System (CMS). 

These digital detectives can swiftly scan websites and reveal the underlying CMS, saving us valuable time and effort. 

Several online platforms are specifically designed to identify the CMS of a website. Some of the notable ones include:

Server and Framework Signatures: The server and framework signatures in the HTTP response can indicate the CMS and technologies in use.

3. Checking for Common CMS Files and Paths

This method involves scrutinizing the files and paths commonly associated with specific CMS platforms. Let’s explore this approach and learn how it can help us identify the CMS behind a website.

Identifying Common CMS Files

CMS platforms often include specific configurations or core files that are unique to them. Here are a few examples:

WordPress: The “wp-config.php” file is a telltale sign of WordPress. It holds critical configuration settings and is present in the root directory.

Joomla: Look for the “configuration.php” file in the root directory. This file contains essential configuration details for Joomla-based websites.

Drupal: Drupal websites frequently have files like “settings.php” or “default.settings.php.” These files are integral to the CMS’s functioning.

Searching for Default Paths

Default administrative paths are another clue that can lead us to the CMS. Here are a couple of examples:

WordPress: The administration area of WordPress is commonly found at “/wp-admin.” So, if you spot this in the URL, you might be looking at a WordPress site.

Joomla: Joomla’s administrative panel is often at “/administrator.” Seeing this in a URL could point you towards a Joomla-based website.

Other Notable Examples

Magento: The administrative path for Magento is typically “/admin” or “/backend.”

Drupal: Drupal’s administration panel path can vary, but it’s often “/admin” or “/user.”

4. Analysing Metadata and Headers

To identify the Content Management System (CMS) that powers a website, Let’s investigate a technique that uses hidden metadata and HTTP headers.

These digital breadcrumbs can lead us to valuable clues about the technology stack. 

Checking the Generator Meta Tag

The HTML source code of a website often contains metadata in the form of meta tags. These meta tags provide insights into various aspects of the website, including its CMS. One such tag is the generator meta tag.

This tag indicates the CMS version or platform being used. For instance, WordPress inserts a generator meta tag explicitly mentioning “WordPress.”

Inspecting Server Headers

Server headers are part of the communication when a user’s browser requests a page from a server. 

These headers can contain crucial information about the server and the CMS in use, which includes:

Server Signature: Some servers include a server signature in their headers, revealing details about the web server and the CMS. For instance, “Apache” might hint at using WordPress.

X-Powered-By Header: This header might disclose the programming language and CMS version powering the website.

5. Using Built-In Features

Many CMS platforms’ default settings and behaviors can inadvertently reveal their presence. Let’s delve into the world of built-in features and how they play a role in our journey through CMS detection.

Analysing Default Error Pages and Login URLs

CMS platforms often include default error pages and login URLs characteristic of their systems. 

These pages can act as subtle clues pointing us towards the CMS used. Some of these pages are:

Error Pages: Some CMSs have distinct error pages containing platform references. By examining the text, formatting, or graphics on these pages, you might be able to identify the CMS.

Login URLs: The login page of a CMS can sometimes be an indicator. For instance, WordPress typically uses URLs like “/wp-login.php,” while Joomla often employs “/administrator.”

Identifying Cookies, Session IDs, or Paths

CMS platforms may utilize cookies, session IDs, or specific paths unique to their system. These elements can provide valuable insights:

Cookies and Session IDs: Some CMSs set cookies or session IDs that include references to the CMS platform. Analyzing these identifiers can offer a glimpse into the CMS in use.

Paths: Certain CMSs use default paths or directory structures for specific purposes. Detecting these paths can give you a clue about the CMS. For example, if you see a path like “/wp-content/themes” in a URL, it’s likely a WordPress site.

6. Reverse IP Lookup

This technique draws upon the fascinating relationship between IP addresses and CMS platforms, offering us yet another method to uncover the technological underpinnings of a website. 

Reverse IP lookup involves examining the IP address associated with a website’s server to gather insights about the technology in use. Certain CMS platforms are associated with specific IP address ranges, which can give us hints about the CMS powering the website.

How Some CMSs Are Associated with IP Ranges
