This attack can be deployed through JavaScript download, as we understand it, which would mean an ad network compromise could have disastrous effect.
Branch prediction is the goal of a CPU or GPU to execute commands before those commands are explicitly issued to the CPU or GPU.
In the instance of this attack, some data can get left behind in L1 Cache, which should be protected data. What we’re most curious in is the impact to workstation and production-type applications, as they straddle the line between consumer and enterprise.
For example, Google engineers created a Spectre exploit POC that, running inside a KVM guest, can read host kernel memory at a rate of over 1500 bytes/second. Additionally, because Meltdown and Spectre require malicious code to already be running on your system, let this be a reminder to practice good online safety behaviors. To guard against the security flaw and the exploits, the first and best thing you can do is make sure you're up to date with your security patches. This has severe implications for virtual machine users, primarily those who may slice servers into virtualized environments for customer use. Meanwhile, AMD shares are soaring on word that the easier-to-pull-off Meltdown attack isn't known to work on its processors.
In fact, fixes have already begun to hit Linux, Android, Apple's Meanwhile, Microsoft told Business Insider it's working on rolling out mitigations for its Azure cloud platform.
As the New York Times notes, researchers are concerned that the fixes could slow down computers by as much as 20% to 30%. All rights reserved. When we asked Intel for a statement, we were sent As for the Spectre attack, the team notes that this exploit has been verified on Intel, AMD, and ARM processors, and notes that it will work against nearly every type of computer – including smartphones and cloud servers.Google has confirmed that Android is affected, and has issued a security advisory about the attack, Intel issued a statement, and AMD issued a statement. A verification code will be sent to you.

With speculative execution, processors essentially guess what you're going to do next.

With an I5 8600k and a GTX 1070TI I've noticed a slightly lower, but more consistent framerate and...
The Meltdown whitepaper indicates a root-cause being branch prediction on CPUs, particularly speculative prediction – the foundation for Spectre’s name. This will be the next major milestone, and will be a point at which the more general consumer community should obtain a better understanding of what’s going on and if it changes the way their PCs perform. He recalls his first difficult decision with GN's direction: "I didn't know whether or not I wanted 'Gamers' to have a possessive apostrophe -- I mean, grammatically it should, but I didn't like it in the name. And, just as importantly, here's what they're not.The Meltdown attack only seems to work on Intel processors. And the problem could affect much more than just personal devices. Is your Power Limit and Ratio-Checker tool, that is custom made by you, available somewhere for public? Neither of the latter have much information, while Google has published some of the most detail on the subject, if you are interested in further reading. Publicly, Intel is confident the Meltdown and Spectre bugs won't have a material impact on its stock price or market share, given that they're relatively hard to execute and have never been used (that we know of). The flaw potentially could be exploited on servers and in data centers and massive cloud computing platforms such as Amazon Web Services, Microsoft Azure, or Google Cloud. So clearly, there’s a lot of math involved there.
