SSL Certificate Reviews

SSL Reviews

Guys, it has been 1 months since my last blog post was really busy with stuff related SSL Certificate. I was busy with some one. In past couple of days I have found that there are many SSL Certificate Reviews.

Most of SSL Certificate Reviews are regarding brands and service provided either by vendor or their partners. SSL Certificates are not reviewed as they are available forms. There are major three SSL Certificate Domain Vetted(Verified) SSL Certificate (DV SSL Certificates), Organization Vetted(Verified) SSL Certificates (OV SSL Certificates) and Extended Validated SSL Certificate (EV SSL Certificates).

I will review SSL Certificates as their type would be much better to make you understand what SSL Certificate you should trust more:

1) Domain Vetted(Verified)( SSL Certificate (DV SSL Certificate) :

Most sold SSL Certificates are Domain Vetted (Verified) SSL Certificate. Because it is cheaper and issued within couple of minutes. Does not require much documentation and anyone can get it. Need only phone verification or email verification to email which either belongs to whois or email address as following :

  • admin@domain
  • administrator@domain
  • webmaster@domain
  • hostmaster@domain
  • postmaster@domain
  • Plus any address listed in the technical or administrative contact field of the domain’s WHOIS record, regardless of the addresses’ domains.

Mozilla Firefox is not recommending this practice because this has security risk on this. Many SSL Certificate vendor uses for example person register domain for 2 years but gets SSL Certificate for 5 years. What will happen if domain expires and another person get that domain and person who had domain and uses existing SSL Certificate to misuse it using DNS spoofing. This is highest risk certificate, I personally don’t trust DV certificates. There is DV wildcard certificate. WildCard SSL Certificate can be used for phishing. Someone can use WildCard SSL certificate for phishing attack, like installing SSL Certificate for https://paypal.xyz.com and you trust this site as it has SSL Certificate and famous payment gateway. One who trust SSL Certificate would think this is Paypal site and will do transaction there. Hence, I would not recommend to trust DV SSL Certificate because one can get SSL Certificate easily and can manipulate with internet security.

I will write about Organization Vetted SSL Certificate and Extended Validated SSL Certificate in my next blog post stay tuned to learn more about the same.

Comodo RA Compromised

Mar 31

I know it is too late to write about this but I came to know about this couple of days ago.

Comodo has confirmed that three registration authorities (RAs) affiliated with the company were compromised first reported on 23rd March 2011 by Iranian hacker to get fraud SSL Certificate for yahoo, google, Microsoft and Skype.

The Certificate was signed by third party without sufficient proof of identity and other information required.

The certificates could have been used by a fraudster to create a fake website that was able to bypass a browser’s validity mechanism and appear like the real thing to users.

Comodo has updated their most recent CRL (Certificate Revocation List) with removal of SSL Certificate.

Customers don’t need to do anything since the update is typically loaded automatically. As well, web browsers with the Online Certificate Status Protocol (OCSP) enabled will block the phony certificates from being used. Researcher Jacob Appelbaum first reported the problem to Comodo but withheld disclosure until the certification authority could remediate the issue.

The intruder, calling himself “Comodohacker,” has posted several lengthy documents on the text-sharing site Pastebin, offering up details about the incident. In the latest document, posted Tuesday, the hacker said it was a difficult infiltration that took time.

“From listed resellers of Comodo, I owned 3 of them,” the hacker wrote.

While rogue certificates were quickly revoked, the incident was serious enough to prompt Comodo to institute new controls and for the major web browsers – Mozilla’s Firefox, Microsoft’s Internet Explorer and Google’s Chrome – to issue updates to their browsers last week.

In response to rampant concerns about the trustworthiness of its certificate generation system from customers, browser companies and others in the security community, Comodo’s Alden said the company is in the process of rolling out hardware-based, two-factor authentication for its resellers to ward off attacks in the future.

The process could take several weeks to complete and, in the meantime, Comodo has promised to review all reseller validation work prior to issuing any certificates.

Mozilla, in particular, criticized Comodo for allowing RAs to issue certificates directly from the root that the company maintains, a practice that eliminated some possible attack mitigations. In response, Comodo said it plans to move away from this practice.
