Computer forensics Computer forensics Presentation Transcript

  • What is an “index.dat?” Group Five
  • Index.dat Only works with Windows version of Internet Explorer. It compiles a list of every site or URL someone visits on the explorer. Very hard to remove the files from the system totally. “The address, time of visit, images, scripts, tracking cookies and web page contents are saved to your hard drive” (Inc., 1998)
  • In essence, it saves everything you view on your computer. (Even if by mistake.) Stores everything which jeopardizes your privacy and personal information.
  • Major issue with Index.dat is that it stores one’s credit card information Worse yet, some people don’t know this information is floating around on their hard drive and their computers might go to sites that they are unaware of.
  • This makes it easier for one’s personal information to be stolen. “Chrome” by Google and “Firefox” by Modzilla as well as “Norton” have better features to clear such information.
  • Aids in investigations Files that may contain child pornography or theorist activity are saved into these files... Leading to a quicker arrest with more solid evidence.
  • Problems arise when it comes to deleting the files. These are called “inderx.dat removers” They gain access to the files and your personal information before removing them.
  • Who is using it? Can be used by many people... FBI for investigations Home Business Workers use them to work offline from home, but still at higher speed rates.
  • Popular Investigation Murder of Caylee Anthony A Myspace page had been created on the day Caylee disappeared by Zenaida, or so Casey Anthony says. The last day that the page was accessed was the day the grand jury indicted Casey Anthony for the murder of her daughter which was the day she was sentenced to prison for the final time.
  • However, upon further investigations, the account was found to be made by Casey Anthony. Who was having notifications sent to herself for the account.
  • Also extremely helpful when tracking child pornography. Man was arrested for searching for child pornography on his company’s system, investigators later traced this back to him.
  • Home Business Workers Makes it easier for people to work offline at home. Allows access of previous visited pages.
  • Index.dat is hard to find because it is a system file and is hidden. Can be found in... Cookie folder, history folder, as well as daily and weekly.
  • Within these folders URL names, time stamps and dates and pointers to the actual cache or cookie files are stored. This is the information that allows you to use “auto complete” and allows you to highlight links that imbedded into another page.
  • Once you decode the information, it allows you to access every website, file, document, picture that you have opened.
  • Removing the Index.dat Many removal tools. You will have to reboot your system and preform a clean-up. Downside to these removal tools is that they get all of your information before deleting it. They also run from 30 to 50 dollars. Some tools only work with certain versions.
  • Whether you delete index.dat or not, you will create new index.dat every time you use your computer! Be careful when sharing your personal information online, it is accessible!
