Alias Equals Zone? Large-Scale and Stealthy Takeover of Domain Hosting Service via CNAME-Following Cross-Domain Verification

1. The HostingEye directory contains code for detecting the hosting status of email services and web services of domains. The input file follows the format <alias>,<canonical>, where <alias> denotes the alias domain and <canonical> denotes the canonical domain.2. The cname_chain directory contains a dataset of CNAME relationships for popular domains and their subdomains. The file top-1m_sld_cname.csv includes CNAME mappings for second-level domains (SLDs), while top-1m_subdomain_cname.csv includes CNAME mappings for subdomains. Each line in these files follows the format <alias>,<canonical>, where <alias> is the alias domain and <canonical> is the canonical domain.1. HostingEye目录包含用于检测域名的电子邮件服务与Web服务托管状态的代码。其输入文件遵循`<别名域名>,<规范域名>`的格式，其中`<别名域名>`代表别名域，`<规范域名>`代表规范域。 2. cname_chain目录收录了面向热门域名及其子域名的CNAME（Canonical Name）关联关系数据集。其中`top-1m_sld_cname.csv`文件包含二级域名（second-level domains，SLDs）的CNAME映射关系，`top-1m_subdomain_cname.csv`文件则包含子域名的CNAME映射关系。两类文件的每一行均遵循`<别名域名>,<规范域名>`的格式，其中`<别名域名>`指代别名域，`<规范域名>`指代规范域。
