Lol! Didn’t check the source. I remembered watching this video a month ago, So I linked it.
After researching more this is the information I found.
This type of attack is only possible with external TPM without PIN protection. (Not a problem for fairly new CPUs with integrated TPM ~5 year old.) This method of breaking into bitlocker isn’t new. A hijaker demonstrated it back in 2013
So, the Linux kernel feature will improve TPM security for older computers
Almost all WMs have this feature
