What do you think WHQL is?

The problem with CrowdStrike's solution is that they got csagent.sys driver signed by WHQL, and the driver will download p-code from the internet and execute it. This allows them to push out changes without waiting for Microsoft approval.

The biggest problem occurs when you don't sanitize your inputs and someone accidentally uploads a blank file padded with zeroes. The driver dereferences a null value, and crashes your system. Hard.

I don't want to argue with you and I admit that my phrasing wasn't ideal but I assumed that it was obvious that i was talking about everything that would be executed on the machine. Apparently it wasn't.

Ahh. Approving every piece of software would make them... Apple.

You did say "driver", and Microsoft typically approves every single driver on the majority of PCs.
