Google Hacking

Google Hacking Abstract Google hacking is the term roled when a hacker tries to find vulnerable tar belongs or sensitive data by using the Google reckon engine. In Google hacking hackers go for lookup engine commands or complex calculate queries to locate sensitive data and vulnerable devices on the Internet. Keywords hacking, hack, Google, Google hack, hacking techniques, attack, ethical hacking, research engines, search engine hacking What is Google Hacking? Google hacking is the term utilize when a hacker tries to find vulnerable targets or sensitive data by using the Google search engine.In Google hacking hackers call search engine commands or complex search queries to locate sensitive data and vulnerable devices on the Internet. Although Google hacking techniques are against Google terms of advantage1 and Google blocks wellknown Google hacking queries, nothing sight stop hackers from crawling websites and launching Google queries. Google hacking preserve be used to l ocate vulnerable web servers and websites which are listed in the Google search engine database.In other(a) words, hackers can locate many thousands of vulnerable websites, web servers and online devices all around the world and select their targets randomly. This kind of attack is most commonly launched by applying Google hacking techniques to meet junior hackers. It is obvious that the Google hacking procedure is based on certain keywords, which could be used effectively if they are used by some internal commands of the Google search engine. These commands can be used to help hackers narrow down their search to locate sensitive data or vulnerable devices.Nevertheless, the success of Google hacking techniques depends on the humans of vulnerable sites, servers and devices. However, we should not ignore the power of the search engines in providing schooling about the targets to the hackers in the reconnaissance phase. Beyond Vulnerability Malicious hackers can use Google hacking techniques to identify vulnerable sites and web servers for known vulnerabilities. In addition, they can look for erroneous belief pages with the help of technical Page 1 of 8 nformation or guess files and directories with sensitive contents such as databases, passwords, log files, login pages or online devices such as IP cameras and network storage. Google Proxy Hackers can use the Google transubstantiate service (http//translate. google. com/translate_t) as a proxy server to visit a website or translate the contents of the website or URLs without leaving any footprints. Figure 1 Google Translate Service. Google Cash Google copies the content of a website in its database. This function helps users to main course the content of the website if the site is not available.However, a hacker can use this function to access and visit a targeted website without leaving any footprint and in complete anonymity. Figure 2 The red cycle indicates the link to access the Cached page. Page 2 of 8 Directory Listings Web server applications such as Apache and IIS provide facilities that a user can browse and navigate website directories by clicking on the directory name and golf links such as Parent Directories. The directories and their content can be listed if directory listing or directory browsing are enabled by the administrator.This vulnerability gives an unauthorized access to the files and it whitethorn help hackers to gain access to the information which can help them to hack a website or a web server or download its contents. Directory listings learn the parent directory links available to browse directories and files. Hackers can locate the sensitive information and files just by simple browsing. In Google it is easy to find websites or web servers with enabled directory listings because the title of the pages start with the index of phrase so we can use index of in the search box to find the directory listings-enabled website.If we command to get better bequea th from our search we can use this combination in the search box intitleindex. of or we can use intitleindex. of Parent Directory. Figure 3 The result of using intitleindex. of Parent Directory. It is obvious that with the first command we used the Google search engine to search in its database for the websites which have been listed with the title of Index of. In the second command we used Google to search for sites with the directory listings and with the keyword which is often found in the directory listings.Specific Directory Hackers can locate specific directories by using the directory name in their search queries. For instance to locate an admin directory in addition to directory listings, the hacker can use these commands intitleindex. of. admin or intitleindex. of inurladmin. Page 3 of 8 Figure 4 The result of using intitleindex. of. admin. Specific File It is possible to search for a certain file by directory listings. For instance, to search for the password. mdb file, th is search query can be used intitleindex. of password. mdb .Figure 5 The result of using intitleindex. of. password. mdb. Specific File Extension Google lets users search its database for a specific file extension by using the filetype command. For instance, if you want to search for pdf files, then you can use the query filetypepdf in the search box. Server Information It is possible to use Google hacking techniques to determine the version of the web server application along with directory listings. This kind of information is vital to an attacker because it will Ali Jahangiri www. alijahangiri. rg Page 4 of 8 help him or her to use the best counselling to attack the web server. For instance, hackers can use the search query intitleindex. of server at to find the web sites with vulnerable directory listings which are operated by an Apache server. Figure 6 The result of intitleindex. of server at. Different versions of Microsoft IIS servers have wide usage all around the world. I t would be easy to find the servers which are operated by Microsoft IIS 6. 0 servers, which are listed in the Google database by using the query Microsoft IIS/6. server at on the Google search engine. Error Pages The delusion pages and warning pages are informative for hackers because these pages could be used to determine the vulnerability of the target. Most of the time hackers use the error centres as keywords or search phrase to find their targets. For instance, if you use Syntax error in query expression the in the Google search box, you can find the websites which have this error message as an Access error message this message can display path names, function names and filenames which are helpful for the hackers.Page 5 of 8 Figure 7 The result of Syntax error in query expression the. Hackers may use Google to locate vulnerable servers by searching for the error pages of web servers such as IIS. The queries intitlethe page cannot be foundand internet information services ca n be used to search for IIS servers that present error 404. Default Pages Default pages are major sources of information about targets for hackers. They use Google to find live servers which are on the default page most of the time, these servers have default configurations with many vulnerabilities.Login Pages The login pages can be use for brute force attacks and gain unauthorized access to the target. In addition, the login pages can be useful to provide information about the target server. For instance, if we use the search query allinurlexchange/logon. asp in the Google search box, we can find the login page of the Microsoft Outlook Web Access. For the typical login page in the web applications or portals which have been programmed by ASP, you can use inurllogin. asp or inurl/admin/login. asp.Figure 8 The result of allinurlexchange/logon. asp. Locating CGI-BIN Common Gateway embrasure (CGI) is a standard protocol for interfacing external application software with web servers. Hackers can use Google to locate the CGI-BIN applications or pages to target. For instance, the search query inurl/cgi-bin/login. cgi locates the login pages base on CGI-BIN. Online Devices It is possible to create special search phrases to locate online devices such as IP cameras, network storage and printers with Google.In this technique hackers use the default pages or the application names which vendors used for hardware and that have been supplied by vendors.

Here is another example to locate online Linksys network storage with the GigaDrive Utility, you can use the search phrase intitleGigaDrive Utility in the Google Search box. Figure 9 The result of inurlindexFrame. html Axis. Google Hacking Database There is an unofficial website (http//johnny. ihackstuff. com/ghdb. php) which acts as a database for hacking of Google. This database has been used since its creation in 2004 by the Google hacking community. You would be able to develop your own Google hacking database by studying the behaviour of the equipment and identifying the pages, page titles and files which can be called and accessed by user and which will be listed in Google.
