To make my report less suspicious I searched Pastebin for real, compromised private keys belonging to certificates. This again shows how problematic the leakage of private keys is: I easily found seven private keys for Comodo certificates and three for Symantec certificates, plus several more for other certificate authorities, which I also reported. These additional keys allowed me to make my report to Symantec and Comodo less suspicious: I could hide my fake key report within other legitimate reports about a key compromise.
