Public Assets Discovery

One way to discover public cloud resources that belongs to a company is to scrape their webs looking for them. Tools like CloudScraper will scrape the web an search for links to public cloud resources (in this case this tools searches ['amazonaws.com', 'digitaloceanspaces.com', 'windows.net', 'storage.googleapis.com', 'aliyuncs.com'])

Note that other cloud resources could be searched for and that some times these resources are hidden behind subdomains that are pointing them via CNAME registry.
