prefetch

🔑 Keypoints:

artifact to prioritize for collection as it can be overwritten during DFIR execs
existence of prefetch does not mean the successful execution
digits in the filename stands for the PE path hash
multiple prefetch for the same PE, can mean different locations (different PE path hash)
exception: PE path hash for ‘svchost’, ‘dllhost’, ‘backgroundtaskhost’, ‘rundll32’ take into account the ‘path + command-line’

🩺 Status:

shimcache

🔑 Keypoints:

subsystem allowing a program to invoke properties of different OS versions
compatibility modes are called “shims”
data buffered in memory / committed in registry on shutdown and reboot
app is shimmed if rewritten, renamed, moved
existence of InsertFlag does not mean the successful execution (OS behavior variation)

What is it ? In a forensics, the table below tend to help identify interesting regripper plugins to run on which evidences.

Note: refer to heaxacorn for the full listing/mapping of regripper plugins to hives.

Note: Run the plugins for ntuser.dat and userclass.dat, as many as the number of evidences (two per users) collected.

What is it ? System and registry hives can be tampered to hide compromise / make the forensics harder. The table below lists the evidences to figure out if anti-forensics happened.

Evidence Type	User hives	System hives
Registry transaction logs (.LOG)	%UserProfile% %UserProfile%\AppData\Local\Microsoft\Windows	%SystemRoot%\system32\config\
Transactional registry transaction logs (.TxR)	%UserProfile% %UserProfile%\AppData\Local\Microsoft\Windows	%SystemRoot%\System32\config\TxR
Deleted entries in registry hives	unallocated cells
Backup system hives (REGBACK)	%SystemRoot%\System32\config\RegBack
Hives backed up with System Restore	\\.\"System Volume Information”

reg-extra

Extra: Live collection of a locked hive :

# useful when having remote access but system handle do not allow read/copy/download 
# batch: registry hive live collection
reg save HKLM\SYSTEM system.reg

Extra: live browsing a hive in CLI : ```powershell
powershell: listing the registry hives
Get-ItemProperty HKLM:\SYSTEM\CurrentControlSet\Control\hivelist\

powershell: browsing a hive with the interpreter
