What is IOC defanging?

Defanging is the practice of modifying Indicator of Compromise (IOC) strings—such as replacing http:// with hxxp[://] and . with [.]—so that software applications, chat clients, and email systems do not render them as live clickable hyperlinks or trigger automatic DNS lookups.

What is IOC refanging?

Refanging reverses defanged notation back into valid RFC-compliant URLs, domain names, and IP addresses so security analysts can query them in sandbox environments or SIEM platforms.

Are IOC strings sent to any server?

No. All text manipulations execute directly in your browser's JavaScript engine. No threat intelligence, internal domains, or network logs ever leave your machine.

Security IOC Defanger & Refanger

Neutralize malicious URLs, domain names, IPv4/IPv6 addresses, and email contacts for safe incident ticket sharing, or refang defanged IOCs back into functional addresses. 100% private in-browser.

SOC Incident Response Standards

Prevents Accidental Clickthroughs

Defanging replaces live web protocols and root domain dots with bracketed syntax, rendering malicious phishing links non-clickable in ticketing systems like Jira, ServiceNow, and Slack.

STIX & MISP Compatible

Follows standard threat intelligence notation used by MISP, AlienVault OTX, and VirusTotal, ensuring smooth parsing across security analysis pipelines.

Zero Data Exposure

Incident logs often contain proprietary customer hosts and sensitive internal subnets. Processing is 100% browser-resident without external API calls.
