The amount of information you can gather about an organization’s business and information systems that is widely available on the Internet is staggering. To see for yourself, the techniques outlined in the following sections can be used to gather information about your own organization.
Social media sites are the new means for businesses interacting online. Perusing the following sites can provide untold details on any given business and its people:
Facebook ( www.facebook.com )
LinkedIn ( www.linkedin.com )
Twitter ( https://twitter.com )
YouTube ( www.youtube.com )
As we’ve all witnessed, employees are often very forthcoming about what they do for work, details about their business, and even what they think about their bosses — especially after throwing back a few when their social filter has gone off track! I’ve also found interesting insight based on what ex-employees say about their former employers at Glassdoor ( www.glassdoor.com ).
Performing a web search or simply browsing your organization’s website can turn up the following information:
- Employee names and contact information
- Important company dates
- Incorporation filings
- SEC filings (for public companies)
- Press releases about physical moves, organizational changes, and new products
- Mergers and acquisitions
- Patents and trademarks
- Presentations, articles, webcasts, or webinars
With Google, you can search the Internet in several ways:
Typing keywords. This kind of search often reveals hundreds and sometimes millions of pages of information — such as files, phone numbers, and addresses — that you never guessed were available.
Performing advanced web searches. Google’s advanced search options can find sites that link back to your company’s website. This type of search often reveals a lot of information about partners, vendors, clients, and other affiliations.
Using switches to dig deeper into a website. For example, if you want to find a certain word or file on your website, simply enter a line like one of the following into Google:
Web-crawling utilities, such as HTTrack Website Copier ( www.httrack.com ), can mirror your website by downloading every publicly-accessible file from it, similar to how a web vulnerability scanner crawls the website it’s testing. You can then inspect that copy of the website offline, digging into the following:
- The website layout and configuration
- Directories and files that might not otherwise be obvious or readily accessible
- The HTML and script source code of web pages
- Comment fields
Comment fields often contain useful information such as names and e-mail addresses of the developers and internal IT personnel, server names, software versions, internal IP addressing schemes, and general comments about how the code works.
The following websites may provide specific information about an organization and its employees:
Government and business websites:
www.hoovers.com and http://finance.yahoo.com give detailed
information about public companies.
www.sec.gov/edgar.shtml shows SEC filings of public companies.
www.uspto.gov offers patent and trademark registrations.
The website for your state’s Secretary of State or similar organization can
offer incorporation and corporate officer information.
Background checks and other personal information, from websites such as:
