Mikko Hypponen notes the following:
There’s a possible message in the rogue certificates that might link Diginotar breach to the Comodo / InstantSSL breach in March.
From “Comodo Hacker” in March: http://pastebin.com/74KXCaEZ – Look at the ending. One of the Diginotar certs was for JanamFadayeRahbar.com
Diginotar hacker created a certificate for the website of another CA: startssl.com. If I were them, I’d check my system carefully.
