URL Defanger
Convert suspicious URLs and IPs to safe defanged text for reports, and restore them with fang mode.
Defang and fang URLs for safer sharing
Security analysts defang indicators so email clients and chat apps do not auto-link malicious hosts. This tool replaces schemes, dots, and at-signs with bracketed forms, and fang mode restores the original text when you need to test a link again. Combine with URL Extractor when triaging long log files.
Typical defanging rules
https://becomeshxxps[://]- Periods in domains and IPs become
[.] - Email addresses use
[@]instead of@
