Prefetch 2.0: Next-Gen Forensic Artifacts
Key Metadata Enhancements
| Artifact | Win10/11 Changes | Forensic Value |
|---|---|---|
| Compressed MAM Format | LZ77+Huffman compression | 34% smaller footprints with identical evidentiary value |
| Execution Traces | Up to 8 timestamps per PF | Establish attacker dwell time (median 42 days in breaches) |
| Volume DNA | NTFS vs. ReFS support | Detect anti-forensic mounting techniques |
“Modern attackers disable prefetch in 78% of intrusions – making surviving records more valuable” – SANS FOR508 2024
The Siftgrab Advantage
Automated Processing Pipeline
Raw PF Fileslibscca ExtractionML-Based Anomaly DetectionPivot TablesTimeline VisualizationIOC Cross-ReferenceCore Capabilities:
