Rick, your report [1] states that...

   "...the certificates never left Symantec's secure test labs or the
    QA test machine, and they were never visible to any end user...
    One of these test certificates with a CN=www.google.com was an
    Extended Validation (EV) test certificate and was logged to public
    Certificate Transparency (CT) log servers"

IIUC, this statement claims that, out of all the certs/precerts listed in [2], the www.google.com precertificate [3] is the only one that "left Symantec's secure test labs".


So, when I looked up all of the serial numbers in [2] in crt.sh, I was surprised to find...

  - 2 certs for *.icns.com.au (which you've explained already).

- 2 precertificates, and the corresponding 2 EV certificates, for evgabrieltest.bbtest.com - see [4].

  - an EV cert for symantec-waf01.scutum.jp - see [5].

  - an EV cert for 123Symantec.com - see [6].


Also, when I looked for evidence of any of the other certs in [2] in some of our historical SSL crawler logs, I was surprised to find that...

- the certificate with serial number 14c943, issued by "Equifax Secure Certificate Authority", was in use when we accessed https://avodcdn01-a.akamaihd.net on 9th June 2011 (IP address 184.86.230.82) and 25th June 2011 (IP address 95.101.190.82). This certificate wasn't known to CT until I logged it just now - see [7].

- the certificate with serial number 1962f4d772f9e9c7ef2d09dd40d85a2c, issued by "VeriSign Class 3 Extended Validation SSL SGC CA", was in use when we accessed https://remote.tdsolutionscenter.com (IP address 96.243.213.32) on the 8th, 11th, 13th and 22nd January 2013. remote.tdsolutionscenter.com still resolves to that IP address today. This certificate wasn't known to CT until I logged it just now - see [8].


I also found a copy of the certificate with serial number 64b32, issued by "GeoTrust DV SSL CA" (although for some reason I wasn't able to find a record of where we discovered that cert). This certificate wasn't known to CT until I logged it just now - see [9].
