I just listened to this and can confirm this was said.

But also this more importantly at 1:25:15

Matt:
"i have one piece of knowledge, if you followed my guide you are not vulnetable to it..but I'm not allowed to say what that piece of knowledge is."

Marty:
"hhhm now I'm trying to think.

Matt:
"But don't fucking try to dissect my statement. If you followed my guide you are not vulnerable to it. I'm not allowed to say why. I'm not allowed to say."

NVK knew, he told Matt. Matt knew.

I screen recorded it.
