And because CPU cache memory can be accessed more quickly than regular memory, the process can attempt to access certain memory locations to find out if the data there has been cached — it still won't be able to access the data, but if the data has been cached, its attempt to read it will be rejected much more quickly than it otherwise would.

Security researchers discovered the flaws late in 2017 and publicized them in early 2018. id: (stringFromDataLayer('userId') !== "" ?

Because of the way computer memory works, just knowing the addresses where data is stored can help you deduce what the data is.

There is as of yet no evidence that these flaws have been exploited in the wild, but such exploits would be difficult to detect, and the flaws are so fundamental and widespread that security researchers are calling them catastrophic. 'suppressMonetization': supMontMods.toString(), DoubleClick by Google refers to the DoubleClick Digital Marketing platform which is a separate division within Google. Original Article: China Turns Cyber Weapons on American Small Businesses via APT10. } To keep it short and simple, both Spectre and Meltdown could allow potential attackers to get access to data they shouldn't have access to using the techniques outlined above, but their effects are somewhat different: Spectre and Meltdown both open up possibilities for dangerous attacks. Even code that is formally secure as written turns out to be vulnerable, because the assumptions underlying the security processes built into the code — indeed, built into all of computer programming — have turned out to be false.
