THE CASE:
The hazardous materials team is called suddenly at 3a.m. May 10 to a warehouse
behind Roma St station in Brisbane. Team member Moti identifies the scene as a drug
manufacturing location, and the people there have hurriedly packaged up the loose
powders they were working with, leaving traces on the floor and across many desk
surfaces. Moti makes a decision not to call the forensic squad in when he sees the
drug traces, because he suspects the drug is at the top of the current most dangerous
list and he needs to take samples back to his lab for analysis before identifying it.
However, Moti is familiar with the protocol when there is a computer in the area, and
calls his colleague Sandra, waking her at 3:17a.m. to walk him through a capture of
computer data for forensic analysis. He is able to shut down the laptop, and removes it – essay bishop
from the scene along with several CDs found in the desk.
Later that day, Sandra analyzes the laptop and CDs in the police forensics lab. The
computer is equipped with Windows and only a basic Word document facility and
Internet Explorer, a program called “OpenPuff”, and has software for showing DVDs
and image files. No documents appear to have been stored on the machine. Three of
the CDs are actually DVDs with recent movies. The fourth contains a suspicious ZIP
file.
Sandra makes three forensic copies of all the data and stores two of them safely in the
lab. She then delegates the laptop and CDs to various staff members for analysis,
distributing the third copies to them. As most of the staff are also involved in a large
on-going investigation she decides to ask for the help of an additional team member
who is holidaying overseas.
You receive a secure e-mail from Sandra with an attachment containing two NTLM
hash strings retrieved from the criminal’s laptop, the ZIP file from one of the CDs
along with a request to analyse it as quickly as possible for any pertinent information,
and an apology for interrupting your holiday.
The two NTLM hashes are:
