IOC Extractor and Defanger.
Paste a report, email or log. Pull out the indicators, and make links safe to share.
Runs in your browser. Nothing you paste is uploaded, and nothing is ever opened or looked up.
Extractor
Find every indicator in the text.
Links, domains, IP addresses, emails, file hashes, CVE numbers and ATT&CK techniques. Already defanged text is understood too.
Why defang
Make it harmless to share.
Break the link on purpose.
Writing hxxps://evil[.]example stops email, chat and documents from turning a malicious address into a clickable link, so nobody opens it by accident.
Turn prose into a list.
Reports bury their indicators in paragraphs. A clean list of domains, IPs and hashes is what you paste into a firewall, a SIEM or a ticket.
Reverse it for analysis.
To search a log or check a domain, you need the live form. Refang puts the dots and colons back, ready to copy into your own tools.
