You’d hope that’s unlikely, but unfortunately it is not. Microsoft left a backdoor in UEFI/Bootlocker to specifically support this. It’s also had a history of major security issues, and a vendor who does not understand how to deal with vulnerability reports. They aren’t on Apple laptops though, just most OEMs. Personally, I think it’s absolutely fantastic that this has finally been publicly exploited in the wild and repurposed for malicious purposes, because this was called out as an obvious threat almost 10 years ago now, and none of the vendors took it seriously or cared. Now they can’t ignore it with the “we have no reports of any customers being attacked” deflection and they will likely face far more scrutiny. It’s just like what happened with the Intel ME staying under the radar for so long, but at least to Intel’s credit, they actually attempted to build security in.
