Bryce Whitty has a list of 7 situations you may find yourself in as a consultant, and asks how you would handle them. There’s some interesting discussion going on in the comments.
I do have one comment, regarding number 7 “A male client wants you to setup monitoring software on his wife?s computer because he believes she is cheating on him. Do you do it and get paid? or decline?”
Absolutely, I decline and here’s why. In the short time I’ve worked with evidence, I’ve learned the important idea of always doing everything by the book. If you follow the same process, regardless of the case, or the evidence, and that process is defensible, your work never becomes an issue at trial and you don’t have to make an appearance to defend it. This situation is the exact antithesis of that. Your work is the case, and how you collected it is absolutely at issue. You can almost guarantee you’ll be in court defending your work and what you collected. Unless you work in the PC forensics field, as a private investigator, or some other field where this is common place, you don’t want to start down that road.
Not to mention, as some of the commenters pointed out, if the PC turns out to be hers, you are guilty of hacking. I wouldn’t want to take that chance. But maybe that’s just me. 🙂
