๐ Introduction
With increasing awareness of data security, more and more people are paying attention to file metadata security issues. Various metadata viewing and cleaning tools have appeared on the market. But did you know? Most of these tools have a fatal flaw: they only process the file's own metadata, ignoring metadata from nested attachments within the files.
๐ Limitations of Most Metadata Tools
Let's look at the limitations of common metadata tools on the market:
1. System-built tools: Windows' file property viewer, Mac's Get Info, etc., can only view basic file metadata and cannot dive deep into file internals.
2. Online tools: Most online metadata viewing tools can only process the file's own metadata and are powerless against nested attachments.
3. Desktop software: Even professional metadata management software often doesn't support metadata scanning for nested attachments.
๐ Real Cases of Nested Attachment Metadata Leaks
๐ Case 1: Resume Privacy Leak
A job seeker used the system's built-in tool to clean Word document metadata when sending their resume, but forgot that the personal photo inserted in the document contained EXIF information. The photo's GPS location exposed the job seeker's residential address, creating security risks.๐ Case 2: Enterprise Report Business Secret Leak
When an enterprise published a product report, they used a metadata cleaning tool to process the PDF file's metadata, but the Excel spreadsheet embedded in the PDF still retained complete metadata, including creator information, modification time, and data sources. Competitors gained insights into the company's R&D progress and data analysis methods through this metadata.๐ Case 3: Academic Paper Research Information Leak
When a scholar submitted an academic paper, they overlooked the metadata in charts within the paper. Creation time and software version information in the charts led review experts to discover traces of data manipulation in the paper, resulting in rejection.๐ Metadata Online: The Tool That Solves Nested Attachment Metadata Issues
