CyberChef for Beginners: Decode Data Like a SOC Analyst

· 2 min read · By Thimmagurudu Bathini, Lead Trainer and Curriculum Designer

Analysts constantly meet data that is encoded, compressed or obfuscated: a Base64 string in an alert, a hex blob in a log, a URL full of percent signs. CyberChef is a free web tool from GCHQ that decodes and transforms data by chaining small operations. It runs in your browser, and you can download it and use it offline, which is safer for sensitive data.

How It Works

Paste input on the right, drag operations from the list into the recipe, and the output updates at once. Each operation does one thing, and a recipe chains them. Search the operation list for the name you need.

Operations to Learn First

  • From Base64 and To Base64.
  • From Hex and To Hex.
  • URL Decode.
  • Extract IP addresses and Extract URLs, for pulling indicators out of a long report.
  • Defang URL, which makes a malicious link safe to paste into a ticket.
  • Magic, which guesses the encoding for you.

Worked Example: Encoded PowerShell

Attackers often run PowerShell with -EncodedCommand followed by a long string. That string is Base64 of text in UTF-16. In CyberChef, add From Base64, then Decode text and choose UTF-16LE. The command appears in plain text, and you can see what it downloads or runs. Seeing such a command in a Sysmon process-creation event is a common SOC task.

Safe Habits

  • Decode only; do not run what you decode.
  • Use the offline copy for company data.
  • Save useful recipes in your notes so you can reuse them.

Where It Fits

CyberChef helps in phishing analysis, malware analysis and forensics. It supports the log and triage work in our SOC, Splunk, Wazuh and DFIR course.
