Understanding File Entropy

What is Entropy?

Entropy measures the randomness or unpredictability of data. Higher entropy (closer to 8 bits/byte) indicates more random data, while lower entropy suggests more predictable patterns.

High Entropy Files
  • • Encrypted files
  • • Compressed archives
  • • Random data
  • • Media files (video, audio)
Low Entropy Files
  • • Plain text documents
  • • Source code
  • • Structured data (CSV, XML)
  • • Uncompressed images
