Vanliga skadeorsaker och hex-återställningsguide
⚠️ Word displays error: 'The file is corrupt and cannot be opened'.
Grundorsak: Damaged ZIP container structure or malformed XML in word/document.xml.
Återställning: Rename .docx to .zip, run 'zip -FF broken.zip --out fixed.zip', extract word/document.xml, fix XML syntax errors with an XML editor, and re-zip.
Säkerhetsanalys och attackvektorer för tolkar
DOCX files cannot contain active VBA macros (.docm is required for macros), making them safer than legacy .doc files, but external template injection remains a risk.
Kända attackvektorer
- Remote template injection pointing to malicious external dotm templates.
- XML External Entity (XXE) vulnerabilities in unpatched document parsers.
- Embedded OLE objects disguising executable malware.
Rekommenderade skyddsåtgärder: Disallow macro-enabled files (.docm) on public upload portals, inspect '_rels' for untrusted external URI templates, and sanitize XML inputs.
Historiskt ursprung och milstolpar
Viktiga fördelar
- Open XML packaging allows automated document generation and text extraction without Microsoft Word.
- ZIP compression significantly reduces file size compared to legacy binary .doc files.
- Modular structure isolates corrupt components, preventing entire document loss.
Tekniska begränsningar
- Visual rendering can vary across LibreOffice, Google Docs, and Microsoft Word due to font layout heuristics.
- Not designed for fixed-layout archiving (unlike PDF/A).
- Complex ECMA-376 specification with thousands of legacy compatibility tags.
Intressant teknisk kuriosa
- Renaming a .docx file to .zip allows you to extract all embedded images directly from the 'word/media/' folder.
- The primary text content of any Word document resides in the file 'word/document.xml'.
Vanliga tekniska frågor
How can I extract all pictures from a DOCX file without Word?
Change the file extension from '.docx' to '.zip', open the archive with any unzipping tool, and browse to the 'word/media/' folder. All original high-resolution photos and graphics are stored there.
What is the difference between .doc and .docx?
.doc is a legacy proprietary binary format used in Word 97–2003. .docx is a modern open standard (ISO/IEC 29500) based on XML and ZIP compression, offering smaller file sizes, greater recovery reliability, and no macro execution capability.
