Applications with Warrants In Mind

The Law  Why are there laws specifically for computer crimes?  A persons reasonable right to privacy  The nature of computers and electronics  Probable cause  Why are there laws specifically for computer crimes?  A persons reasonable right to privacy  The nature of computers and electronics  Probable cause

Search and Seizure  Basically identical to previous laws with exceptions to the actual allowable procedure for searching and/or seizing.  In both cases a warrant must be obtained before searching and seizing, but the conditions for each are different.  The exemption to a warrant is probable cause, but this is difficult for electronics  Basically identical to previous laws with exceptions to the actual allowable procedure for searching and/or seizing.  In both cases a warrant must be obtained before searching and seizing, but the conditions for each are different.  The exemption to a warrant is probable cause, but this is difficult for electronics

The Process  Crime is suspected  Suspects are watched  Their system is qualitatively analyzed  When enough substantial evidence is acquired a warrant is requested and granted by a magistrate judge.  They go to physically analyze the system  Crime is suspected  Suspects are watched  Their system is qualitatively analyzed  When enough substantial evidence is acquired a warrant is requested and granted by a magistrate judge.  They go to physically analyze the system

Important things to Think about  The criminal computers are in most cases standard PC’s or laptops, but also are many times servers.  It is important to know what OS the machine is running.  Is the machine booby trapped?  Where should I look for data?  The criminal computers are in most cases standard PC’s or laptops, but also are many times servers.  It is important to know what OS the machine is running.  Is the machine booby trapped?  Where should I look for data?

The File System  Are the desired files hidden within other data types  Could the files be in hidden (invisible) directories  What programs could be running?  Is there a program set to wipe the whole drive upon boot up if a special password or key is not entered.  Are the desired files hidden within other data types  Could the files be in hidden (invisible) directories  What programs could be running?  Is there a program set to wipe the whole drive upon boot up if a special password or key is not entered.

Time constraints  How long will it take to get the warrant?  With proper evidence it should not take long.  How long will the warrant last?  Usually the warrant will last about a month.  How long is too long to hold on to a suspects computer?  Depends on the nature and size of system.  How long will it take to get the warrant?  With proper evidence it should not take long.  How long will the warrant last?  Usually the warrant will last about a month.  How long is too long to hold on to a suspects computer?  Depends on the nature and size of system.

Analyzing the Evidence  Much of the work in analyzing a system is hardware related  In most cases the first thing to do is make a copy of the hard drive  Once a hard copy is made they data can be sorted with out worry of contamination  They use hard drive duplicators  Much of the work in analyzing a system is hardware related  In most cases the first thing to do is make a copy of the hard drive  Once a hard copy is made they data can be sorted with out worry of contamination  They use hard drive duplicators

Forensics Software  SubRosaSoft in addition to making data recovery software for consumers and IT professionals also makes forensics software  MacForensicsLab keeps track of every action and window/button click; records date time of action.  SubRosaSoft in addition to making data recovery software for consumers and IT professionals also makes forensics software  MacForensicsLab keeps track of every action and window/button click; records date time of action.
