What is a Spectre attack?
Spectre is a vulnerability that tricks a program into accessing arbitrary locations in the program's memory space. An attacker may read the content of accessed memory, and thus potentially obtain sensitive data. In particular, Spectre centers on branch prediction, which is a special case of speculative execution.
.
Consequently, what does meltdown and Spectre do?
Meltdown and Spectre exploit critical vulnerabilities in modern processors . These hardware vulnerabilities allow programs to steal data which is currently processed on the computer. Meltdown and Spectre work on personal computers, mobile devices, and in the cloud.
One may also ask, what is the difference between Spectre and meltdown? The difference is that Meltdown takes advantage of a specific Intel privilege escalation issue to do this, while Spectre uses the combination of Speculative Execution and Branch Prediction. Both issues can be addressed with software patches, but this is more effective for Meltdown than Spectre.
Hereof, how dangerous is Spectre?
What makes Spectre uniquely dangerous is its ability to cause permanent, physical damage to your computer. For this reason, Spectre presents a core problem much more substantial than an average virus or malware.
Should I worry about Spectre and meltdown?
The simple answer is that if you're using hardware made within the past 10 or so years, then yes, almost certainly. Whether you're using a PC, a Mac or an iPad Pro, if it's not patched against Meltdown and Spectre then it's a potential target.

Is AMD affected by Spectre?
AMD processors aren't affected by the Meltdown bug. Chips from Intel, AMD, and ARM are susceptible to Spectre attacks. AMD says its hardware has “near zero” risk to one Spectre variant because of the way its chip architecture is designed, but AMD CPUs can still fall prey to another Spectre flaw.Are 8th gen Intel processors affected by meltdown and Spectre?
Intel CEO Brian Krzanich today announced that its next-generation Xeon Scalable (Cascade Lake) processors and its 8th-generation Intel Core processors will feature redesigned components to protect against the Spectre and Meltdown vulnerabilities that affect all modern processors.How does Spectre attack work?
Spectre is a vulnerability that tricks a program into accessing arbitrary locations in the program's memory space.

Ernst Stavro BlofeldWhat is a speculative execution attack?
Speculative execution is an optimization technique where a computer system performs some task that may not be needed. Work is done before it is known whether it is actually needed, so as to prevent a delay that would have to be incurred by doing the work after it is known that it is needed.Who created Spectre?
