Figure 3 shows the process the actors used to turn their IPv6 IP address range into a domain they could use in phishing emails. For a normal reverse DNS lookup, the entire IP address is needed to calculate the reverse DNS string. However, since the threat actor operates a /64 range, the last 64 bits of the address can be ignored. To make their reverse DNS domains harder to detect and block, they prepend the domain with a randomly generated subdomain to make each FQDN unique.
