Phishing URL checker & domain reputation lookup

Use the vspam.org search to check whether a URL, domain, IP address, or email address has been reported as malicious. Our community-driven database is updated in real time as reporters submit and verify new indicators of compromise (IOCs).

What you can look up

• Phishing URLs — check if a suspicious link has been reported as a phishing or credential-harvesting page.
• Domain reputation — look up any domain to see if it is associated with phishing, malware distribution, or spam campaigns.
• IP reputation — check whether an IP address is listed in our IP RBL for spam, botnet C2, or brute-force activity.
• Email sender verification — search for email addresses used in phishing or BEC (business email compromise) campaigns.

All lookups are free. For programmatic access, use the REST API or integrate our DNSBL feed directly into your mail server.
