일반적인 손상 모드 및 헥스 복구 가이드

⚠️ Word displays error: 'The file is corrupt and cannot be opened'.

근본 원인: Damaged ZIP container structure or malformed XML in word/document.xml.

복구: 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.

보안 분석 및 파서 공격 벡터

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.

알려진 공격 벡터

Remote template injection pointing to malicious external dotm templates.
XML External Entity (XXE) vulnerabilities in unpatched document parsers.
Embedded OLE objects disguising executable malware.

방어적 모범 사례: Disallow macro-enabled files (.docm) on public upload portals, inspect '_rels' for untrusted external URI templates, and sanitize XML inputs.

역사적 배경 및 주요 이력

2008ISO/IEC 29500 formalizes Office Open XML as an international open standard.

2006Microsoft introduces DOCX with Microsoft Office 2007, replacing legacy binary .doc.

주요 장점

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.

기술적 제한 사항 및 단점

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.

흥미로운 기술적 상식

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'.

자주 묻는 기술 질문

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.
