It's worth noting the "goto fail" bug was likely exploited, so it had value to someone. As has been shown through various leaks, the NSA and other entities like it have a war-chest of these toys. Things that used to be "you're just being paranoid" type concerns are now "we may never know" ones.
Regardless of the origin or intent, it still paints Kapersky in a very, very bad light. There's no escaping that.
