From the above, it can be seen that usually but not always , the most sensitive information can be retrieved from the last method, namely two-way interaction with a specific target. It is assumed that the researcher has the knowledge to conduct the basic mainstream searches, but wants to go further and obtain more results without needing the levels of permission, time and budget required by the other levels.
Open Source Intelligence Methods and Tools
Do not be put off at the first, second or fifth hurdle. Leaked information is not meant to be found and will require some persistence and creativity to pay dividends. Traditional security audit tools — even those that are designed to conduct OSINT searches, while useful, fail to retrieve the full breadth of information that can be obtained about a particular person or organisation, and so should not be used exclusively.
Google Google is usually the first place to conduct searches. When all the basic variants on a search term have been exhausted, such as using different spellings of a search term, using quotes around search terms and also asterisks for wild card searches, some more advanced search terms will need to be used.
The following search types, in particular, either used alone or in combination with each other, are very useful for most cases: 4 Open Source Information Research filetype: this restricts the search to a specified file type e.
Some of the most sensitive information can be obtained from files which are directly accessible on the Internet.
Using the term ext: plus file extension , is often a very effective method. Some example file extensions include: txt, doc, docx, pdf, xls, bak, log, cgi, asp, php, conf, mdb, pst, ini and pl. Such information includes the technologies in use, assets and internal structure.
People often use the same usernames for more than one platform. Check the last part of the URL for the actual username pertaining to the profile you are looking at. Also check the comments left in target posts, images, photographs and the names of friends and contacts.

Photos and videos Photos and videos should be included in most OSINT searches as they can provide information on locations, associations, contacts, technical vulnerabilities and evidence of online crimes.
Google is a good place to start, using the standard image search and also the face search refinement option within Google images. As with the above, you can get as creative as you like. Useful search terms for finding technical vulnerabilities include office, team, security, reception, server, maintenance, building, computer, hardware, software, network, party, event, visitor, property, presentation, talk, meeting, room, staff and so on.
Vulnerabilities that can lead to technical or non-technical attacks on a company can be found in all sorts of company photos from laptop screens being visible, to whiteboards with diagrams on them, security badges being worn by staff, the make of CCTV, network wall ports, routers, reception security and so on.
Social media sites usually have plenty of official and unofficial corporate photos and videos.

In addition to the information that can be gleaned from just looking at images, it can also be useful to get further information from photos. It is possible to upload the image in question to various online photo forensic sites or download a free photo analyser to get possible details on the time and date the photo was taken, the device used to take the photo and the location the photo was taken from.
A reverse image search e. If there are some screenshots in any Word documents you have obtained, it is sometimes possible to identify those images that have been cropped.
Un-cropping the images in Word can reveal the parts of the image that were not meant to be seen which can then reveal sensitive information.
The principal reasons for this include the fact that OSINT searches are low impact flagging fewer alarm bells , are legal, require little technical expertise and can sometimes be the only way to start to plan a larger attack.
There are many free domain records search sites which will show the publically-held records of websites, domains and IP addresses including the ownership and hosting details. Searches can also be done to check the domain and associated IP addresses for any spam blacklisting.
Traceroute applications can map devices through which network connections take to reach the target. It is sometimes useful to send a test email to the target but using a deliberately wrong name in the first half e.
Legitimate emails from the target can also give this information in the email header of the message.
Most email systems will enable the full header of a message to be displayed. Search for the robot. If the file is shown in the browser, it sometimes lists those directories that web crawlers should not index. Online tools or even just right clicking on a webpage and selecting to view the source will show the HTML code.
These days, web applications are much more secure than in years past, and so usually the best to be hoped for with website source code reviews is to collect information on vulnerable versions of common software and applications. Over resources are identified with narrative tutorials and screen captures.
This book will serve as a reference guide for anyone that is responsible for the collection of online content. It is written in a hands-on style that encourages the reader to execute the tutorials as they go.
Always thinking like a hacker, the author has identified new ways to use various technologies for an unintended purpose. Among other techniques, you will learn how to locate: If you have the 5th edition of this book, you may want to know what has changed in this 6th edition.
The 6th edition is pages 5th edition was , but the retail price of the book remained unchanged. All expired and outdated resources were replaced with new methods throughout every chapter, and the OSINT flow charts were re-built to reflect all changes. Several new online custom search tools were created and implemented into the tutorials for easier search execution.
The chapters were re-written and reorganized in order to allow complete explaination of each topic. Social Networks: Occasionally, techniques for obtaining online information change.SlideShare Explore Search You.
Without repeating the actual wording of these acts, it should be sufficient to know that these OSINT techniques do not impair the function of a computer or hinder access to data held on any system or the operation of any computer application and do not require getting unauthorised access or escalating system privileges.
