Security readout for executives and security teams

Microsoft Office 98 for Macintosh could unintentionally include fragments of previously deleted files inside newly created Office documents. If those documents were shared, sensitive information could be exposed without the sender realizing it. Exposure is most likely in legacy Macintosh environments or archives containing documents created with Microsoft Office 98, Macintosh Edition. The structured affected-product data is incomplete. Treat this as a legacy data-leakage issue, not a modern remote-code-execution emergency. Prioritize if the organization has old Office 98 documents, public archives, legal productions, or historical customer files. Mitigation focus: Check Microsoft KB Q189529 for vendor-specific guidance before choosing remediation.; Identify and retire any remaining Office 98 for Macintosh workflows.; Review legacy Office 98 documents before external sharing or publication..
