フォレンジック調査員のエマは、攻撃者がいくつかのファイルのタイムスタンプ メタデータを改ざんしており、ファイルがいつ作成、アクセス、または変更されたかを正確に判断することが困難になっていることを発見しました。
エマは、隠された証拠を発見するために、タイムスタンプが操作されたファイルを特定する必要があります。NTFSファイルシステムのタイムスタンプの変更を検出するために、エマが使用できるツールは次のどれですか?
正解:A
According to the CHFI v11 Operating System Forensics curriculum, timestamp manipulation is a common anti-forensics technique used by attackers to obscure activity timelines. On NTFS file systems , each file maintains multiple sets of timestamps-such as $STANDARD_INFORMATION and $FILE_NAME attributes-stored within the Master File Table (MFT) . Discrepancies between these timestamp sets are strong indicators of timestamp tampering .
analyzeMFT is a specialized forensic tool designed explicitly to parse and analyze the NTFS Master File Table . CHFI v11 highlights MFT analysis as a critical method for detecting time-stomping attacks , where attackers alter file timestamps using utilities like timestomp. analyzeMFT allows investigators to compare multiple timestamp attributes, identify anomalies, reconstruct timelines, and detect inconsistencies that standard file system views cannot reveal.
The other tools are not appropriate for this task. Regshot is used to compare Windows Registry snapshots, OSForensics is a general forensic suite but is not specifically optimized for low-level MFT timestamp comparison, and Process Explorer is a live system monitoring tool focused on running processes rather than file system metadata.
CHFI v11 explicitly emphasizes NTFS MFT analysis as the authoritative method for identifying manipulated timestamps. Therefore, the most accurate and CHFI-aligned tool for detecting timestamp modifications on NTFS file systems is analyzeMFT , making Option A the correct answer.
