Threat actors are constantly looking for new ways to evade detection, and most techniques are variations on familiar themes. The abuse of the .arpa TLD is novel in that it weaponizes infrastructure that is implicitly trusted and essential for network operations. By using IPv6 reverse DNS domains as malicious links, the threat actor has discovered a delivery mechanism that bypasses security tools.

These domains have an implicitly clean reputation, no registration information, and aren’t usually blocked by policy.
