Spectre is hitting servers especially hard. The software updates to protect the servers are causing performance issues. In other words, when a patch is applied to address the vulnerability, performance decreases perhaps 30 percent.

I see a lot of posts with titles such as “10 signs your interview went well”.. Ok, how about some signs that your interview is NOT going well?

There are two vulnerabilities that were recently brought to light. The essence of these attacks is that they can establish processes that can read the supposedly secure data from other processes.
Suppose you are logged in to your bank via the web. There is data there about account numbers, balances, passwords etc. Some of that will be encrypted. However, the exploit MIGHT be able to view the unencrypted data. After all, your balance and account numbers need to be displayed in a format you can read.
The analysis and assessments of the Spectre and Meltdown threats are still coming in. This is something that both business owners and individuals should keep a close eye on.
To recap, these exploits allow an attacker to ‘see’ data from other applications running on your systems. This is a HUGE screwup of epic proportions on the part of the chip and software designers.
According to an article by an article on CNBC, Intel’s CEO reportedly sold shares after the company already knew about massive security flaws.
He made something like 25 MILLION in the deal.
Cert has published links to guidance from vendors regarding Meltdown and Spectre. It includes Amazon AWS, Android and numerous other vendors. You almost certainly have to apply the patches but the performance impact is hideous (30 percent).
See the CERT bulletin for details.
Windows has released a patch, January 3, 2018—KB4056892 (OS Build 16299.192), that is supposed to help address the Meltdown and Spectre vulnerabilities.. BUT some owners of AMD based machines are reporting crashes.
This thing is turning into a giant mess. The microsoft update January 3, 2018—KB4056892 (OS Build 16299.192) is supposed to patch the Meltdown/Spectre vulnerabilities. It doesn’t say so directly but the following in the KB article seems to indicate that is one of the features of the update.
There has been a lot of speculation that the software patches to OS’s to address the Meltdown, Spectre could result in a 30 percent performance decrease . The update installed on my laptop on Jan 3rd and the results are..
