I don't think this is really relevant to malware detection.  You can't
do syscalls from SGX code, for example, and, even if you could,
malware behavior analysis would be unaffected.  The concern seems to
be more that, once someone has discovered some malware, if it's
protected by SGX then it's plausible that you can't disassemble it.

I don't know if Linux gets full credit for this, but I think we at
least had some impact.
