hpHosts Classification Explanation

Note: Sites without a current classification are shown as "TBV" (To Be Verified). This means they are still awaiting classification. If you find a site listed without a classification, please contact me so it's reviewal can be sped up.

The following classifications are used to determine the reason for inclusion into hpHosts and have been published here for those wondering what the classification means when viewing the domain's information on the hpHosts Online website.

  1. ATS - Ad/tracking servers
    This classification is assigned for domains being used for advert or tracking purposes
  2. EMD - Sites engaged in malware distribution
    This classification is assigned to website's engaged in the distribution of malware (e.g. adware, spyware, trojans and viruses etc).

    Sites with this classification typically either contain files (e.g. cracks, keygens, adware, spyware, trojans, viruses et al) or lead to such via (for example) "fake scanners" or other social engineering and misleading tactics. This includes the activities of rogue Internet Service Providers (ISPs) that host other sites to which the EMD classification applies.
  3. EXP - Sites engaged in the housing, development or distribution of exploits, including but not limited to exploitation of browser, software (inclusive of website software such as CMS), operating system exploits aswell as those engaged in exploits via social engineering.
