1/2 “This is a very surprising bug that evaded the quality control on Mac OS High Sierra. Apparently, it also works on FileVault in the Mac OS, which makes this bug quite problematic.” – @TylerM_Webroot, Sr. threat research analyst. https://t.co/q1ZIVoPCia

2/2 “We expect @Apple to release a fix for this vulnerability. In the meantime, any payloads that are found to use this exploit will certainly be added to our threat database to be blocked.” – @TylerM_Webroot, Sr. threat research analyst.

It seems that Apple was able to publish a user guide explaining how to defeat the exploit for now.
