By now you’ve probably heard. A large portion of the world’s computer processors are vulnerable to at least one of two exploits that render them susceptible to hackers. But what, exactly, is going on — and what can you do to protect yourself?

While the answer to the first question is complicated, thankfully the answer to the second isn’t. It turns out that companies like Google and Microsoft have been working behind the scenes to create patches for what the security community has named Meltdown and Spectre. 

But we’re not out of the woods yet, and, depending on your operating system, you still need to take some proactive measures to make sure your data is safe.  Read more…

So your computer is probably vulnerable to a processor chip bug that could theoretically let JavaScript running in a web browser steal your passwords (among other problems). Both your computer and your smartphone are at risk. It’s not good. 

Thankfully, however, for anyone with a machine running Windows, you’re probably in the clear. That’s because on Wednesday, January 3, Microsoft released a fix.

So reports ZDNet, which explains this patch was not issued on Microsoft’s standard Patch Tuesday — suggesting someone at the company decided it was urgent. Importantly, a Microsoft support page notes that the fix only applies to devices running Windows 10.  Read more…

While Apple scrambles to issue a software fix for a major macOS High Sierra vulnerability, astute observers are wondering what took the company so long to react — after all, the problem was known about weeks ago. 

It seems that on November 13, a commenter on an Apple developer forum disclosed the very vulnerability that today threw the infosec community into a frenzy. Oh, and it was called out 9 days ago on Twitter as well. 

And just how bad is this security threat? Well, it’s not good. Essentially, it gives anyone with access to an unlocked computer the ability to set themselves as the root user — as well as log back in later to the locked computer at a time of their choosing. Read more…

How to protect yourself from the massive macOS High Sierra security vulnerability

So your macOS High Sierra-running machine is vulnerable to hackers. Like, really vulnerable. 

Thankfully, there’s a simple way to protect yourself — so long as you can follow a seven-step process laid out Tuesday by Apple. 

News broke Nov. 28 on Twitter that an attacker could gain root-user access to an unlocked computer simply by typing “root” into the “User Name” field, leaving the password field blank, and hitting “enter” while in the “Users & Groups” section of “System Preferences.”

You can access it via System Preferences>Users & Groups>Click the lock to make changes. Then use “root” with no password. And try it for several times. Result is unbelievable! pic.twitter.com/m11qrEvECs
