2009 M57-Jean

The M57-Jean scenario is a single disk image scenario involving the exfiltration of corporate documents from the laptop of a senior executive. The scenario involves a small start-up company, M57.Biz. A few weeks into inception a confidential spreadsheet that contains the names and salaries of the company’s key employees was found posted to the “comments” section of one of the firm’s competitors. The spreadsheet only existed on one of M57’s officers, Jean.

Jean says that she has no idea how the data left her laptop and that she must have been hacked.

You have been given a disk image of Jean’s laptop. Your job is to figure out how the data was stolen, or if Jean isn’t as innocent as she claims.

  1. I had the same problem and I converted the image to dd (raw) format to open it using p2 commander.

    For conversion I used ftk imager

    Best regards

  2. For me, I put the 2 files .E01 and .E02 in the same directory and the sleuthkit command work like a charm. I realize that .E01 and .E02 is only one file. If you rename .E02 in .E02.back you must write the second file in the same line like this :
    mmls nps-2008-jean.E01 nps-2008-jean.E02.back

  3. Is there a way students can get the password to the solution because i wanted to use this case for a class presentation?
