About:
Ssdeep computes and compares context-triggered piecewise hashing (CTPH) signatures, also known as fuzzy hashes. This technique allows for the detection of similar data within files, even when they differ by small modifications. It is particularly effective for identifying malware variants, digital artifacts, and data deduplication.
Key Features:
  • Computes fuzzy hashes using CTPH
  • Compares files to find matches based on similarity scores
  • Recursive directory scanning capabilities
  • Fast processing of large datasets
Use Cases:
  • Digital forensics and incident response (DFIR) for identifying malware variants
  • Plagiarism detection and data integrity verification
  • Finding duplicate or near-duplicate files in large storage systems
Alternatives:
  • TLSH – Trend Micro's fuzzy hashing algorithm, often cited as having better performance and stability for large datasets compared to ssdeep.
  • sdhash – Focuses specifically on forensic data carving and finding similar fragments of data.
