QuestionQ348

Procedures and Methodology

During a high-stakes data-breach investigation at a healthcare provider in Atlanta, Georgia, the forensic team finds evidence of multiple evasion techniques, including hidden payloads in documents, erased log artifacts, and changed timestamps that obscure the intrusion timeline. To systematically address these layered obstructions and ensure comprehensive evidence extraction without depending on a single method, which countermeasure should the team prioritize to improve the reliability and completeness of its analysis?

  • A Employ steganalysis tools and techniques to analyze files for concealed or hidden information
  • B Train and educate forensic investigates about anti-forensic techniques
  • C Use advanced data-recovery tools and methods to extract hidden, deleted, or overwritten data
  • D Use packer detection tools to identify obfuscation methods applied to evidence data and unpack content
Explanation

Advanced data-recovery tools and methods provide the broadest means of locating and reconstructing hidden or deleted artifacts and of assessing partially overwritten data, which can yield corroborating evidence for reconstructing an intrusion timeline. Deleted-file recovery examines file-system metadata and may reconstruct deleted files; recovery results must be validated because fully overwritten data may be unrecoverable or partially reconstructed.
