I didn't see anything to be worried about as iExec has no mention anywhere in that article which was referred at STK platforms vulnerabilities about Intel. They are working well and this kind of finding will be helpful for team iEXec RLC to look at there platform more carefully. RLC is most advance project among others trying to solve these issues.
Sure but I'd like an official statement about RLC team concerning this potential hack.
All their software relies on SGX security, and the SpecterSGX attack make it useless.
