The Shared Security Amazing Thing of the Month
(we’re not sure what to name this new segment so we’re rolling with this for now…)
Tom and Scott discuss the emergency SOS feature on your mobile device. There was a recent story in the news about a college student who was able to text message and send her location when she was being kidnapped. Even though the college student was able to find a way to text and send out her location, there are some easier and more discreet ways that you can make an emergency phone call as well as alert authorities to your location. Here are the instructions we mentioned on the show if you have an Apple iOS 11 device or on your Apple Watch. Android is not left out of the emergency notification party either! Here are details if you have an Android phone to enable or install this feature with an app.
Overview of the Meltdown and Spectre Critical Vulnerabilities
CPU hardware implementations (manufactured in the last 20 years) are vulnerable to side-channel attacks referred to as Meltdown and Spectre. Modern processors perform speculative execution. To maximize performance, processors try to execute instructions even before it is certain that those instructions need to be executed.
The best description of these vulnerabilities is from the original website announcing these issues:
Meltdown and Spectre exploit critical vulnerabilities in modern processors. These hardware vulnerabilities allow programs to steal data which is currently processed on the computer. While programs are typically not permitted to read data from other programs, a malicious program can exploit Meltdown and Spectre to get hold of secrets stored in the memory of other running programs. This might include your passwords stored in a password manager or browser, your personal photos, emails, instant messages and even business-critical documents.
Meltdown and Spectre work on personal computers, mobile devices, and in the cloud. Depending on the cloud provider’s infrastructure, it might be possible to steal data from other customers.
