This network-like structure is a deliberate strategy, allowing operators to move traffic between different sites if one is taken down or blocked, ensuring the continued availability of their content. The use of seemingly random TLDs and the sheer number of registered domains (over 68 by one count) make it difficult for authorities and cybersecurity tools to effectively shut down the operation, as new domains can be rapidly deployed to replace those that are lost.

The presence of such content also suggests that the AV4US network was not merely distributing generic malware or operating phishing scams but was engaged in trafficking in the most harmful category of illegal material. This elevates the network from a standard cybersecurity threat to a criminal enterprise requiring law enforcement intervention.
