Summary
Combating phishing attacks using cousin domains requires a comprehensive, multi-layered strategy. This includes proactive domain monitoring for early detection and rapid takedown of fraudulent domains. Contributing to domain-based blacklists (Openphish, Phishtank, URIBL, SURBL) and reporting phishing sites to APWG and Google Safe Browsing are critical. Implementing email authentication protocols (DMARC, SPF, DKIM) prevents spoofing, while educating users through security awareness training and establishing clear brand guidelines reduces the success rate of attacks. Employing advanced threat detection and multi-factor authentication provides further protection. Developing a cybersecurity framework and incident response plan ensures quick identification and recovery. Furthermore, it's important to be cautious about reporting to Cloudflare due to their potential doxing practices, and to understand that UDRP may not always be the most effective solution.
Key findings
- Proactive Monitoring is Key: Continuous domain and brand monitoring are crucial for early detection of cousin domain phishing.
- Blacklisting and Reporting: Adding domains to blacklists and reporting phishing sites enhances community protection.
- Email Authentication: Implementing DMARC, SPF, and DKIM protects against email spoofing.

What the experts say
5 expert opinions
Combating phishing attacks involving cousin domains requires proactive monitoring and strategic reporting. While direct takedowns may be ineffective due to rapid domain rotation, adding cousin domains to domain-based blacklists, such as Openphish, Phishtank, URIBL, and SURBL, is recommended. Reporting to APWG and setting up domain monitoring alerts for brand name variations are also crucial. It is important to avoid Cloudflare for abuse reporting due to their practice of doxing reporters.
Key opinions
- Ineffectiveness of Direct Takedowns: Direct takedowns of cousin domains are generally ineffective because attackers can quickly rotate domains.
- Domain Blacklisting: Adding cousin domains to blacklists like Openphish and Phishtank is a valuable strategy.
- Proactive Monitoring: Continuous domain monitoring with alerts for brand name variations is essential for early detection.
- Reporting Resources: APWG provides a platform for reporting phishing and contributes to collaborative defense efforts.
- Cloudflare Caution: Cloudflare's abuse reporting practices can be detrimental due to doxing reporters.
Key considerations
- Resource Allocation: Prioritize efforts towards monitoring and blacklisting over direct takedowns due to the rapid rotation of cousin domains.
- Alert Setup: Configure domain monitoring alerts to capture common misspellings and brand name variations.
- Reporting Accuracy: Ensure accurate and timely reporting of phishing domains to relevant blacklists and resources.
- Alternative Services: Seek alternative services for abuse reporting that prioritize the safety and anonymity of reporters.
- Blacklist relations: Explore getting an "in" with Google Safe Browsing.
Expert view
Expert from Email Geeks suggests Openphish and Phishtank. Mentions that URIBL and SURBL might be amenable to having a trusted reporter give them domains. Also suggests getting an in to Google Safe Browsing.

Expert view
Expert from Email Geeks shares that going for a takedown of the domains isn’t going to help, as they can rotate cousin domains far faster than that process. Suggests getting the cousin domains added to some domain-based blacklists.

What the documentation says
5 technical articles
Combating phishing attacks using cousin domains involves a combination of dispute resolution, reporting, user education, and incident response planning. ICANN's UDRP can address trademark infringements, but may not be suitable for subtle phishing attempts. Reporting to APWG and Google Safe Browsing helps add phishing sites to blocklists, protecting users. Educating consumers to avoid sharing sensitive information via email is crucial, and developing a cybersecurity framework with incident response plans aids in quick identification and recovery from phishing incidents.
Key findings
- UDRP Limitations: ICANN's UDRP is useful for clear trademark violations but less effective for subtle cousin domain phishing.
- Reporting Benefits: Reporting to APWG and Google Safe Browsing adds phishing sites to blocklists, enhancing protection.
- Consumer Awareness: Educating consumers to avoid sharing sensitive information is a key preventative measure.
- Incident Response: A cybersecurity framework with incident response plans helps in quickly identifying and recovering from phishing.
Key considerations
- Trademark Strength: Assess the strength of trademark infringement when considering UDRP for cousin domain phishing.
- Reporting Strategy: Establish a process for regularly reporting suspicious domains to APWG and Google Safe Browsing.
- Educational Programs: Implement user education programs emphasizing the dangers of sharing sensitive information via email.
