As a result of attack; random folders and files in public_html. What kind of attack is this?

Summary

: The type of attack that could potentially result in random folders and files appearing in public_html is a directory traversal or injection attack. This article will provide an overview of the attack, its impact on websites and how to prevent it.

The appearance of unexpected files and folders in the public_html directory can have several consequences for website owners. It may lead to the compromise of sensitive data, unauthorized access, and loss of integrity of the website content. A common type of cyber-attack that could result in such an outcome is a directory traversal or injection attack.

1. Overview of Directory Traversal Attack

A directory traversal attack is a type of vulnerability where an attacker attempts to exploit weaknesses in the web application by manipulating file paths and directories to access restricted areas or retrieve sensitive data. By using special characters such as “..” or “/”, the attacker can navigate through the server’s file system, potentially gaining unauthorized access to files and folders that are not intended for public access.

2. Impact on Websites

If a directory traversal attack is successful, it could lead to several consequences for websites and their owners. The most common impact of such an attack includes:

– Access to sensitive data: Attackers can gain unauthorized access to sensitive information such as user credentials, personal information, or even source code.

– Loss of website integrity: By modifying files or adding new ones, the attacker could compromise the integrity of the website content, leading to potential damage to the brand reputation.

– Denial of Service (DoS): Attackers can use this type of attack to overload the server with requests, causing it to crash and resulting in a denial of service for legitimate users.

3. Prevention Measures

To prevent directory traversal attacks, website owners should implement the following measures:

– Input validation: Validate all user input to ensure that it only contains permitted characters. This can be done by using regular expressions or other validation methods.

– Server configuration: Configure the web server to deny access to sensitive directories and files. For example, disallowing access to “.htaccess” files, “readme” files, and other system files.

– Keep software up-to-date: Regularly update all software components, including the web application, server software, and operating system, to ensure that any security patches are installed promptly.

In conclusion, directory traversal attacks can have severe consequences for websites and their owners. By understanding the attack and implementing preventive measures such as input validation, server configuration, and keeping software up-to-date, website owners can protect their sites from this type of cyber threat.
