Forensic Image – DB Cooper Lab Assignment

The questions below will build on all of the exercises and labs that we have done in class to date. All of the tools/resources you need should be available on D2L from previous assignments.


In 1971, D. B. Cooper became infamous by hijacking a Boeing 727 aircraft and extorting

$200,000 in ransom. Cooper escaped by strapping his ransom to his chest and parachuting from the exit ramp of the Boeing 727 at 8:13 PM… all while traveling at over 200 mph at altitudes of almost 10,000 ft and temperatures of seven below zero. D.B. Cooper’s body, parachute, and money were never found.

Based on an anonymous tip, on November 10th, 2014 at 4:25 pm Central Time, authorities execute a search warrant at a classified location at a classified location that was reported to be a safe house used by DB Cooper.

At the scene, a team of forensic analysts created a forensic image of a Dell Latitude D610 (Serial Number: X123Y456). This laptop computer is believed to been used by D. B. Cooper.

The authorities have provided you with a copy of this forensic image in the hopes that you can recover any information as to where DB Cooper has been hiding as well as any information where he may be keeping the ransom money.

Warning: The anonymous tip mentioned that DB Cooper’s computer is infected with a live virus, use caution!


Reports will be submitted via D2L as a single PDF file. Please name the report in the following format: “Your Name – DePaul DB Cooper Report” Forensic Image

For each question, document the tool you used and which file/artifact you obtained the answer from. Also note any notable or unusual findings. Make sure to include the results or screenshots of your output in your report.

i.e. The typedurls plugin from RegRipper was used to parse the Software\Microsoft\Internet

Explorer\TypedURLs registry key from the \Users\UserName\NTUSER.DAT registry hive.
