Imagine you, as a forensic investigator, are assigned to investigate a cybercrime involving a Windows-based...

Under theCHFI v11 Operating System Forensicsdomain, investigators are required to analyze Windows file systems and recover evidence that may have been deleted, corrupted, or intentionally destroyed during a cybercrime. File loss incidents commonly occur due to malware infections, insider activity, ransomware attacks, or deliberate anti-forensic actions. Recovering such files is often critical to reconstructing events and identifying attacker intent.

R-Studiois a specialized forensic data recovery tool designed to analyze Windows file systems such asNTFS, FAT, and exFAT. It can scan allocated and unallocated disk space, identify lost partitions, and recover deleted or damaged files while preserving original metadata such as timestamps and file structure. CHFI v11 recognizes file recovery tools like R-Studio as essential forpost-incident Windows forensics, especially when investigators must restore evidence without modifying the source media.

The other options are not appropriate for file recovery.Cain & Abel,Ophcrack, andPwdump7are credential-related tools used for password recovery or hash extraction and do not perform file system reconstruction or deleted file recovery. Using such tools would not help retrieve missing files and would not align with the forensic objective described.

Therefore, in accordance with CHFI v11 Operating System Forensics principles, the most suitable tool for restoring lost files from a compromised Windows system isR-Studio, makingOption Bthe correct answer.
