Email still remains a popular choice for attackers to distribute malicious content. Netcraft Mail Reporter allows you to quickly report suspicious emails directly from your mailbox and receive the results of our analysis,  protecting you and others from malicious messages in your inbox. No need to sign-up and free to use!

We look for a wide range of security threats such as phishing sites, brand impersonation, malicious attachments and malicious activity on web pages such as credit card skimmers or unauthorised cryptocurrency miners.

Links that are successfully identified as phishing will be flagged as dangerous in major web browsers and antivirus software, protecting billions of internet users worldwide.
