AT THE BEGINNING of May, Google released eight new top-level domains (TLDs)—the suffixes at the end of URLs, like “.com” or “.uk.” These little addendums were developed decades ago to expand and organize URLs, and over the years, the nonprofit Internet Corporation for Assigned Names and Numbers (ICANN) has loosened restrictions on TLDs so organizations like Google can bid to sell access to more of them. But while Google's announcement included light-hearted offerings like “.dad” and “.nexus,” it also debuted a pair of TLDs that are uniquely poised to invite phishing and other types of online scamming: “.zip” and “.mov”.
