Intel Expands Bug Bounty Program Post-Spectre and Meltdown
In the wake of the Spectre and Meltdown bugs, Intel has rolled out a significant expansion of its bug bounty program. Intel first launched the program in March 2017. The big changes include a shift from an invitation-only format to one that is open to all security researchers. One key addition is...
What You Should Know About Side-Channel Attacks, Like Meltdown
“The light is on in their window. They must be home.” This is a classic example of a side information channel. They didn’t TELL you they were home. But the side effect of them being home in the evening is the light in the window — which is how you’re pretty sure they are home even though this...
