And here is the response from McAfee guys

Well, Security is all about being one step ahead.
Unfortunately McAfee guys can’t put a strong case forward and the only thing they can come up with is:
“Are we really willing to assume that the security at these vendors are so impenetrable that bad guys couldn’t possibly have messed with the content at the production end? With Joanna’s “elegant” solution, all that a cybercriminal needs to do is to compromise an application vendor to create an infected binary, signed by the vendors certificate and viola”
Well, in a world where majority of the risk coming from majority of day zero malware going undetected, in a world where a simple re-packing of an existing malware is tricking many AVs out there, in a world where the underworld now owns tens of millions of PCs as part of their BOT armies, I would, any day, accept the world where the risk is the risk of application developers being infiltrated by the underworld!
Smell the coffe guys… the days of AV as the first line of defense has well passed its sell by date! Prevention is your first line of defense now!
