Top 100 Bad Hosts - November 2009

As a test of its capabilites during BETA development, SiteVet has produced data on the world's worst web hosts (specifically, Autonomous Systems). This data was produced for HostExploit, who will be releasing a full report on the findings here in late-November.

The top 100 bad hosts are shown below; click each one for further details. You can also download a more detailed PDF report, free of charge, for each of the top 100 bad hosts.

As SiteVet moves out of BETA development, detailed reports will be available for every active AS.

• SiteVet is currently in BETA development. Features that are yet to be implemented are highlighted in blue.
• SiteVet is an innovative and multi-faceted product based on information gathered from years of working in the internet security industry. With this background the SiteVet team identitied that potential buyers of a domain name had no way of "health-checking" sites for previous unethical use. Applying the same commitment as shown in our other security projects (HostExploit, Jart Armin, RBN Exploit), the team developed SiteVet to fill that gap.
• SiteVet can uniquely provide historical data on domains, IP addresses, IP ranges and Autonomous Systems.
• It can be used before buying a domain to run a health check to see if it is already tainted.
• Searches are free to perform, with extensive detailed reports available for a small fee.
• Domain data includes: blacklist status and history, WHOIS history, full breakdown of malicious files and URLs, domain's involvement in specific activities (spam, phishing, exploits, RFI, botnets etc).
• Detailed statistics will be available on Autonomous Systems (servers) and IP ranges; this will be an amalgam of the collective data of domains and IPs in its range, plus advanced calculations which enable a customer to compare the relative badness of different hosting companies, and enable an informed decision on where to host your website.
• The embedded value of a domain will be shown - this will be a monetary value of the domain, based on its SEO and marketing potential.
• SiteVet is also intended for domain buyers who wish to find out if a site’s previous history is in-keeping with the industry it is to be used in. This will provide a guide to a site’s SEO advantages or disadvantages.
• Webmasters will be able to employ our fully compatible blocklists on their systems to provide another level of security protection against malware, malicious scripts, redirects and fake/rogue software downloads.

FAQs

Can I trust the results SiteVet produces?

We are a leading name in the monitoring of websites, hosts and registrars for badness. SiteVet uses our own historically-based data gathered from our own trusted sources and comes with the same level of trustworthiness and reliability on which we have built our reputation.

What will I get when I enter a domain search?

There are different levels for different purposes:

• Level 1: Free search that shows an overview of domain reputation and current blacklist status.
• Level 2: This requires registration to SiteVet. Entry of a domain name at this level will produce an in-depth result including historical information on previous usage of the selected domain name or IP address.
• Level 3: Paid report that shows extensive details - blacklist history, WHOIS history, IP and AS changes, specific infected files, specific exploit methods used.

Can I just check if a domain name has a known bad reputation?

Yes, just enter the domain name or IP address and search.
