Out on a branch, speculating about possible architectural flaws

The discovery of yet another variant of Spectre vulnerability is not good news for already exhausted security experts or reporters, but there is something new in this story which offers a glimmer of hope.  A collaborative team of researchers from Northeastern University and IBM found this newest design law using an automatic bug finding tool they designed, called Speculator.

They designed the tool to get around the largest hurdle security researchers face, the secrecy of AMD, Intel and ARM who are trying to keep the recipe for their special sauce secret, and rightly so.  Protecting their intellectual properly is paramount to their stockholders and there are arguments about the possible effectiveness of security thorough obscurity in protecting consumers from those with nefarious intent but it does come at a cost for those hunting bugs for good. 

Pop by The Register for details on how Speculator works.
