Several people who received the CrowdStrike offer found that the gift card didn't work, while others got an error saying the voucher had been canceled.
…sorta. The complexity here is their driver is signed, but it’s also loading code from their channel file (that was all zeroed out), and it seems the necessary error checking wasn’t implemented.
I haven’t yet got to the root cause they published, this is just what I gathered from the video of a retired MS kernel dev who posts stuff.
Obviously with their design it allowed them to be flexible at the cost of playing with fire - I’m impressed they got away with it for so long, really
Thank you for the clarification. WHQL is such a pain to set up, I’m sure the AV vendors whined, “but, security! Do we have to test everything every time? That would slow an urgent 0day release!”
