Cell Site Analysis (CSA) is the technical discipline of using mobile telephony signals and network data to triangulate and identify the relative geographic position of a device.
The Windows Registry is stored in multiple files.
+
  
===Windows NT 4 ===
+
Cell site analysis is considered a highly intrusive surveillance technique and as such normally deployed only in sensitive or serious criminal investigations.
In Windows NT 4 (and later) the Registry is stored in the [[Windows NT Registry File (REGF)]] format.
+
  
Basically the following Registry hives are stored in the corresponding files:
+
The technique can assist in demonstrating the co-location (meeting) of individuals, their movements over time, proximity to a scene of crime, and to verify the any defence alibi evidence.
* HKEY_USERS: \Documents and Setting\User Profile\NTUSER.DAT
+
* HKEY_USERS\DEFAULT: C:\Windows\system32\config\default
+
* HKEY_LOCAL_MACHINE\SAM: C:\Windows\system32\config\SAM
+
* HKEY_LOCAL_MACHINE\SECURITY: C:\Windows\system32\config\SECURITY
+
* HKEY_LOCAL_MACHINE\SOFTWARE: C:\Windows\system32\config\software
+
* HKEY_LOCAL_MACHINE\SYSTEM: C:\Windows\system32\config\system
+
  
===Windows 98/ME===
 
* \Windows\user.dat
 
* \Windows\system.dat
 
* \Windows\profiles\user profile\user.dat
 
 
== Keys ==
 
 
=== Run/RunOnce ===
 
System-wide:
 
<pre>
 
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run
 
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\RunOnce
 
</pre>
 
 
Per user:
 
<pre>
 
HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\Run
 
HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\RunOnce
 
</pre>
 
 
== Special cases ==
 
The Windows Registry has several special case scenarios, mainly concerning key and value name, that are easy to fail to account for:
 
* special characters key and value names
 
* duplicate key and value names
 
* the names when stored in extended ASCII (ANSI string) use a codepage that is dependent on the system settings
 
 
=== special characters key and value names ===
 
Both key and values names are case insensitive. The \ character is used as the key separator. Note
 
that the \ character can be used in value names. The / character is used in both key and value names.
 
Some examples of which are:
 
<pre>
 
Key: HKEY_LOCAL_MACHINE\SYSTEM\ControlSet002\Services\NetBT\Parameters\
 
Value: Size/Small/Medium/Large
 
</pre>
 
 
<pre>
 
Key: HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Control\Terminal Server\VIDEO\disc\
 
Value: \Device\Video0
 
</pre>
 
 
<pre>
 
Key:
 
HKEY_LOCAL_MACHINE\SYSTEM\ControlSet002\services\xmlprov\Parameters\SchemaGroups\User\http://www.microsoft.com/provisioning/eaptlsuserpropertiesv1\
 
Value: SchemaFile
 
</pre>
 
 
=== codepaged ASCII strings ===
 
 
Value with name "ëigenaardig" created on Windows XP codepage 1252.
 
 
<pre>
 
value key data:
 
00000000: 76 6b 0b 00 46 00 00 00  20 98 1a 00 01 00 00 00  vk..F...  .......
 
00000010: 01 00 69 6e eb 69 67 65  6e 61 61 72 64 69 67 00  ..in.ige naardig.
 
00000020: 55 4e 49 43                                        UNIC
 
 
value key signature                    : vk
 
value key value name size              : 11
 
value key data size                    : 0x00000046 (70)
 
value key data offset                  : 0x001a9820
 
value key data type                    : 1 (REG_SZ) String
 
value key flags                        : 0x0001
 
        Value name is an ASCII string
 
 
value key unknown1                      : 0x6e69 (28265)
 
value key value name                    : ëigenaardig
 
value key value name hash              : 0xb78835ee
 
value key padding:
 
00000000: 00 55 4e 49 43                                    .UNIC
 
</pre>
 
 
As you can see the name is stored in extended ASCII (ANSI) using codepage 1252.

Cell Site Analysis (CSA) is the technical discipline of using mobile telephony signals and network data to triangulate and identify the relative geographic position of a device.

Cell site analysis is considered a highly intrusive surveillance technique and as such normally deployed only in sensitive or serious criminal investigations.

The technique can assist in demonstrating the co-location (meeting) of individuals, their movements over time, proximity to a scene of crime, and to verify the any defence alibi evidence.
