Sandsifter throws random machine code instructions at microprocessors, just to see what happens.
The sandsifter audits x86 processors for hidden instructions and hardware bugs, by systematically generating machine code to search through a processor's instruction set, and monitoring execution for anomalies. Sandsifter has uncovered secret processor instructions from every major vendor; ubiquitous software bugs in disassemblers, assemblers, and emulators; flaws in enterprise hypervisors; and both benign and security-critical hardware bugs in x86 chips.
With the multitude of x86 processors in existence, the goal of the tool is to enable users to check their own systems for hidden instructions and bugs.
I demand to see this scene in technothrillers pronto.
For more than two decades, researchers have explored using DNA as a chemical computer. Until now though, DNA computers have only been capable of solving whatever mathematical problem they were built to tackle. Now though, researchers have demonstrated a more general-purpose DNA computer that can run a variety of chemical “programs.” From Caltech: “Think of […]
There aren’t many details in Trump’s “American A.I. Initiative,” but the point appears to be: send a message of technological dominance to China.
Over at EDGE.org, the must-read hub of intellectual inquiry and head-spinning science, Boing Boing pal and legendary book agent John Brockman is launching a new series of essays “from important third culture thinkers to address the empirically-driven and science related hot-button cultural issues of our time.” First up is author George Dyson’s “Childhood’s End,” a […]
Despite government legislation and improving caller ID technology, robocalls and scam artists are rampant on the phone lines – up to 35 billion a year in the US alone. They can be annoying at best and a financial threat at worst, but there’s a way to take security into your own hands. One good example […]
If you’re a Mac user, you thrive on simplicity. Everything in its place and a place for everything. Unsurprisingly, there’s a ton of great organizational apps out there for Mac, and now someone’s had the great idea to bundle them all together. Whether you’re running a demanding business or just getting through the day to […]
Seems like drones are doing a lot of jobs these days, from reconnaissance to delivery. Now, we can add “keeping the Death Star safe” to that list. Whether you’re a drone enthusiast or a Star Wars fan, these Star Wars Propel Drones are undeniably the coolest toy around. Yes, that’s a fully functional drone replica […]
