-
metadata and EXIF analysis
-
deleted file recovery
-
timeline generation
Plaso / log2timeline
A powerful framework for creating multi-source forensic timelines from:
-
logs
-
registry hives
-
browser artifacts
-
system events
-
application data
Wireshark & NetworkMiner
For comprehensive network packet analysis, PCAP inspection and extraction of transferred files.

How SANS SIFT Works and How It Is Used
SIFT can be deployed as:
-
a virtual machine (VMware / VirtualBox)
-
a standalone Linux installation
-
a Cloud forensic workstation (AWS, Azure)
A typical workflow includes importing:
-
disk images (E01, AFF, RAW)
-
memory dumps
-
PCAP files
-
registry hives
-
log archives
-
browser artifacts
Analysts then perform:
-
Data acquisition and validation
-
Forensic parsing of artifacts
-
Malware and memory analysis
-
Timeline building
-
Correlation of events
-
Incident reconstruction
-
Reporting and documentation
Real-World Use Cases of SANS SIFT
SIFT is designed for practical DFIR scenarios such as:
-
ransomware investigations
-
analysis of phishing and malware payloads
-
detection of lateral movement
-
investigation of Windows artifacts (AmCache, ShimCache, SRUM)
-
detecting data exfiltration
-
cloud breach analysis using logs and PCAP
-
post-compromise disk forensics
Its wide toolset allows deep investigation of even the most complex incidents.
