A confidential Microsoft Word document requires a forensic-level review of its metadata. The objective is to determine whether the file is truly authentic by inspecting every trace the application leaves behind and documenting any sign of tampering or manipulation. The examination must explicitly cover: • Time-stamp consistency across all revision layers • Overall document integrity (hash comparisons, hidden revision blocks, embedded objects) • Validity and chain of any digital signatures I do not need the metadata altered; the focus is on deep analysis and clear proof. Please provide, as your final deliverable, a concise report describing the tools and methods you used, the evidence you located, and your conclusion on authenticity, supported by screenshots or hash values where appropriate.
