Forensics Investigation as Computer Crime?
OWADE (Offline Windows Analysis and Data Extraction) is an open source forensics tool for extracting “hidden” data from the hard drive of a Windows PC. According to New Scientist, OWADE enables an investigator to “bypass” the encryption Windows uses to store data on the hard drive so the investigator can discover web browsing history, including user IDs and passwords. New Scientist, “New forensics tool can expose all your online activity,” Sept. 7, 2011.
I wonder whether OWADE violates the Windows EULA or other legal restrictions Microsoft asserts with respect to Windows.
For example, paragraph 8 of the End User License Agreement for Windows 7 Professional says the user may not “work around any technical limitations in the [Windows] software.”
What is the implication of an investigator violating the Windows EULA when he gathers data? Is the investigator committing a computer crime? Is he accessing a computer without authority and causing harm (paraphrase for violating the Computer Fraud and Abuse Act)?
Is he infringing privacy law?
Is he opening himself to a lawsuit from any person who is harmed?
Is he rendering the data he collects inadmissible as evidence in court?
What do you think?
[Update: I wonder whether use of OWADE would violate the Digital Millennium Copyright Act (DMCA). 17 USC Sec. 1201 (a)(1) (A): “No person shall circumvent a technological measure that effectively controls access to a work protected under this title.” The argument might be this: 1. The Windows user used Windows to make records of his “work” (i.e. codes showing his browsing activity and history). 2. He used the encryption in Windows to control access to his “work.” 3. OWADE circumvents the encryption.
DMCA is complex. I note that DMCA contains many exceptions, including certain exceptions for law enforcement.]

Mr. Wright teaches the law of data security and investigations at the SANS Institute.
If I understand the question correctly, your asking if you are violating the EULA of Windows on a computer you examine because you accepted the Agreement on another Windows computer?
In perusing the windows 7 license, it says it is licensed "per copy per computer basis". The investigator would have had to accept the EULA for the computer they are examining, no? I think that's unlikely.

Rob: Your analysis sounds logical. Still, I'm not sure your analysis answers all the possible arguments about whether the investigator is doing something illegal.
Does it not feel fishy for an investigator to "bypass" encryption that is intended to protect privacy?
Thank you for your excellent comment. --Ben

Surely the Windows EULA only applies if you are running Windows. If you are using software on Linux or some other OS to analyse data on a disk the EULA does not apply, does it? Regardless of what OS was used to create the data. The DMCA and privacy issues are a different matter though.
