DCForums:
A type of forum and shopping client that many people use can also be exploited through Google. Even though the password files are encrypted most of the time a knowledgeable hacker can decrypt or brute force these passwords. These hashes can potentially contain passwords, usernames, and email addresses.
SQL databases:
It is also possible to get config.php files from Google for SQL databases as well. These config.php files can contain user names and passwords for the databases, which make them potentially harmful. As most sites that have forums run SQL databases, sometimes a hacker can get access to full admin status to the database in this way.
etc directories in websites:
One very misunderstood concept is the vulnerability of the etc directory in many different types of websites; you name the site, it probably has an etc directory. Most of the time the information from this directory can be accessed by Google deep web searches, and it sometimes contains the sensitive information of the site’s users or webmasters.
Backup files from websites:
While many webmasters like to backup their information/website directories/programs on the Internet, most don’t know that this can lead to harmful effects if hackers with a malicious intent get a hold of them through Google deep web searching. The hacker could use the backup as a spring board to understanding the website or program better, causing deadly consequences as a result.
