Summary
Handling false positive reports from Netcraft and typo-squatting spam traps requires a comprehensive approach. Identifying suspicious domains and scrutinizing sign-up legitimacy, especially IP addresses, is crucial. Proactive measures include setting up typo-squatting domains, strict input validation, confirmed opt-in (COI), regular sunsetting of inactive subscribers, and careful content review for spam triggers. Understanding how security services like Netcraft, Spamhaus, Google Safe Browsing, and Microsoft SmartScreen operate is vital for preventing misclassification. Reactive measures involve establishing whitelisting processes and promptly addressing complaints, building rapport with reporting organizations, and understanding the ever-present threat of malicious actors.
Key findings
- Domain Validation: Domains resembling common typos are often linked to spam traps and should be treated with suspicion; use a 'bad domain' list.
- Input Validation: Implement strict input validation on email signup forms, including real-time suggestions.
- Subscriber Management: Regularly sunset inactive subscribers and use confirmed opt-in (COI) to minimize spam trap exposure.
- Reputation Monitoring: Monitor domain and IP reputation using tools to detect and address listing that can assist in dealing with the fall out from false positive.
- Understanding Security Services: Understand how Netcraft, Spamhaus, Google Safe Browsing, and Microsoft SmartScreen identify and flag potentially malicious content.
- Proactive Monitoring: Monitor for common typos of your domain to catch errant traffic and potential abuse by typo-squatting spam traps.
Key considerations
- Complaint Handling: Be prepared to handle complaints promptly and effectively, with resources for incorrectly classified users.
- Reporting Organization Contact: Contact reporting organizations (e.g., Netcraft) to dispute false positives, providing evidence of legitimate practices.
- Typo Squatting Defense: Set up typo-squatting domains to intercept misdirected emails and prevent spam trap exposure.
- Defense Mindset: Acknowledge the existence of malicious actors and implement proactive security measures, with understanding of double-opt in weaknesses.
- AWS' Complaint Handling: AWS recommends promptly addressing bounces and complaints, even if suspected false positives, to maintain a positive sender reputation.
- Spamhaus' Data Sources: Spamhaus relies on honeypots, spam traps, and user-submitted reports to identify and track spam sources.
- IP Address Validation: The IP address of email confirmation clicks should be scrutinized, as atypical IPs may indicate automated or malicious activity.
