普通人应该关注哪些方面？

对于普通读者而言，建议重点关注Reverse DNS domains are only intended for internet infrastructure purposes, but DNS can be challenging to implement correctly and there are sometimes unintended behaviors. Figure 4 shows what happened when we performed a type A query on one of the reverse DNS domains in the phishing emails. DNS servers were queried until the authoritative server for the domain was found. In this case, the authoritative name servers were operated by Cloudflare. Using these name servers, the reverse DNS FQDN resolved to two IP addresses. Both IP addresses belonged to Cloudflare’s edge network, which hides the actual host of—in this case—the malicious content. Although reverse DNS domains aren’t supposed to work like this, the threat actors found a way to make it happen.
