Enlist IT help when installing CPU updates

When it comes to security updates, time is usually of the essence. The longer you wait to install a fix from a vendor, the higher the risk of being compromised. But in the cases of the Meltdown and Spectre flaws, you might be better off waiting until a more reliable patch is released. Let’s review what’s going on and what the best course of action currently is.

Unsecured data storage

Spectre and Meltdown are the names given to two hardware flaws that allow hackers to see any piece of information stored on your computer. Although slightly different in execution, both take advantage of a hardware feature that computer chips use to access and store private information. For the last 20 years, security experts believed this information could not be stolen or spied on by malicious software, but that assumption was proven false on January 3, 2018.

Now that the Spectre and Meltdown vulnerabilities are public information, hackers can use them to create programs that steal passwords, social security numbers, credit card numbers, and anything else you type into your computer.

Because these problems are hardware-based, none of the updates will be able to secure the vulnerable storage; they’ll simply prevent your computer from storing anything in it. Currently, there are patches for:

• Operating systems (Windows, macOS, and Linux)
• Web browsers (Chrome, Firefox, Safari, Edge, and IE)
• Chip firmware (low-level programs installed on the processor itself)

If you’re using an Apple computer, these updates are relatively easy to install. If you’re using a Windows or Linux-based computer, these patches may cause your machine to freeze, reboot unexpectedly, or significantly slow down.

Why should I wait to install the updates?

Intel, one of the chipmakers responsible for the Spectre and Meltdown flaws, has provided contradictory recommendations on more than one occasion. As recently as January 18, Intel recommended waiting for an updated patch, but in the same announcement also recommended “consumers to keep systems up-to-date.”

Experts believe detecting an attack that is based on one of these flaws will be relatively easy and represent an alternative to installing updates that could render your computer unusable.

What should I do?

IT support experts will be able to quickly and easily assess what is the best option for your computers. For example, our team can determine whether or not your hardware will conflict with the current patches, and either install them or set up a detection strategy that will help you mitigate the risks without ruining your computer.

Critical browser vulnerabilities discovered

According to security researchers, a bulk of the world’s computer processors have gaping flaws. The flaws, grouped under the term ‘Spectre,’ affect many critical systems including web browsers like Chrome, Safari, Microsoft Edge, and Firefox. Here’s a quick rundown of these major vulnerabilities and what you can do to secure them.

What is Spectre?
To understand this unprecedented vulnerability, you need to know some computer chip basics. Modern chips try to speed up their work by storing information related to predictable and repetitive processes. Whenever CPUs perform calculations ahead of time that end up being unnecessary, the data is thrown away into a supposedly secure storage cache.

Hackers can gain access to the discarded data by using malware to create digital backdoors. From there, they can simply sneak in, sift through the private information, and even trick the processor into throwing away even more sensitive information. This is known as a Spectre attack.

Though the exploit is highly technical and difficult to execute, researchers said Spectre affects all modern processors, including those developed by Intel, AMD, and ARM.

How does it affect browsers?
As mentioned, hackers would need to install malware on a device to perform a Spectre attack. One tactic experts found effective is if hackers build a malicious program and embed it on a website. Should anyone visit the rogue website, their browser will automatically run the malicious program.

Once inside, the attacker can use Spectre to gain full access to keystrokes, encryption keys, and login credentials.

So far, there is no evidence of Spectre attacks actively being used to steal data from web browsers, but they are difficult to detect. Experts also predict hackers will likely develop specialized malware now that this information is available to the public.

Is there a way to protect myself?
Fortunately, major browser developers were quick to release updates as soon as the Spectre attack was discovered.

Mozilla also has security features to prevent some Spectre attacks, but announced a full-blown solution is in the works.

As for Chrome, users can expect an update as early as January 23. But for the time being Google recommends enabling the Site Isolation feature, which limits how much access browser plugins have to your computer. This feature can be enabled by going to your address bar and entering: chrome://flags/#enable-site-per-process.

Even though the updates may affect browser performance, it’s a small price to pay compared with having your credit card or social security number stolen.

Like it or not, Spectre is just one of the many threats targeting your web browsers. That’s why you should call us today. We offer expert advice and cutting-edge solutions to make sure your browsing experience is a pleasant and safe one.
