Spectre makes a comeback

When one cyberattack is stopped, another more powerful variant almost always takes its place. It happens all the time with ransomware, computer viruses, and Trojan horses. Recently, this has become the case with Spectre attacks, which exploit a fundamental flaw in modern computer chips. Here’s everything you need to know.

Spectre 101
For those who don’t know, Spectre is a vulnerability in modern computer chips like Intel and AMD that allows hackers to steal confidential information stored in an application’s memory, including passwords, instant messages, and emails. Malicious code running on a computer or web browser could be used to exploit this vulnerability, but ever since Spectre was discovered, Microsoft, AMD, Intel, and other tech companies released a series of updates to fix it.

What is NetSpectre?
To perform Spectre attacks, malware would have to run on a targeted machine to extract sensitive data. But in late July, Austrian security researchers found a way to launch Spectre-style attacks remotely without locally installed malware. The new attack is called NetSpectre and it can be conducted over a local area network or via the cloud.

So far, it’s impractical for average hackers to use this method to steal data. In tests, researchers were able to steal data at a rate of between 15 to 60 bits per hour, which means it would take days to gather corporate secrets and passwords. As such, NetSpectre will probably be used by hackers who want to target specific individuals but don’t want to resort to obvious methods like phishing scams or spyware.

Experts also warn that while NetSpectre may be impractical now, hackers may develop faster and more powerful variants in the future.

How should you protect your business?
NetSpectre attacks exploit the same vulnerabilities as the original Spectre so it’s important to install the latest firmware and security updates. You should also secure your networks with advanced firewalls and intrusion prevention systems to detect potential NetSpectre attacks.

Last but not least, working with a reputable managed services provider that offers proactive network monitoring and security consulting services can go a long way in protecting your business from a slew of cyberthreats.

4 reasons for slow mobile internet speeds

Have you ever gotten frustrated with your phone because the browser took more than five minutes to load? Before you start blaming your old phone, check out these four reasons that might be the cause of sluggish internet connection.

Router location

One simple yet overlooked reason why your WiFi-connected phone may be experiencing internet lag is because of your router’s location. Although WiFi has a range of up to 230 feet, the farther away you are from the router, the weaker the WiFi signal. Large objects like doors and walls situated in between you and the router can also weaken the WiFi signal.

It is recommended to place your router in a central location, preferably away from concrete and masonry walls or other big objects like a chimney. As the router signal radiates from all four sides, blocking any side with big objects will impact your WiFi’s signal quality and as a result your phone’s internet speed.

WiFi Noise

Did you know that home electronic appliances emit wireless signals at a frequency similar to your router’s (2.4 GHz)? So before deciding on your router’s location, determine whether there are any wireless devices nearby, as they emit signals that can interfere with your router’s signal. For example, even if the ideal location for your router is at the center of your house, you shouldn’t place it there if there’s a cordless phone nearby.

You can also set your router on a 5.0-GHz band, as this frequency is less prone to interference from other appliances. But before you start tuning it, make sure your phone supports 5.0 GHz; otherwise, it won’t be able to connect to the router.

Slow Network

Another reason for your phone’s slow internet is because of fluctuating network speed. Ask yourself these two questions to know the exact cause of this problem:
How many people are connecting to the router?
What are they doing over the internet?

You should increase your router’s internet bandwidth speed if you discover you have many users and all of them are either streaming movies, or downloading computer games or software updates. This will allow every phone to enjoy faster internet speed.

If you’re outdoors, and you’re connected to a public WiFi, consider using your mobile data instead. You won’t have to share your internet when you use mobile data, enabling you to experience faster connectivity at all times as long as you have a high-speed data plan.

Too much cache

Last, you should check your phone’s cache if fixing your router, network, and positioning doesn’t improve your phone’s internet speed. Cache is a component in your phone that saves data from earlier searches in order to increase the speed of similar searches in the future. Although your phone becomes more efficient for that particular search, it also makes your phone much slower when you do other things that require the internet.

You can clear out your cache manually or use a cache cleaner app to thoroughly get rid of useless cache and optimize your phone’s internet speed. If you decide to download a cache cleaner app, make sure that it is reputable and trustworthy so you don’t accidentally download a malware-infiltrated app instead.

There are more reasons to your phone’s lagging internet speed. If your business relies heavily on fast mobile internet speed and you’re unable to fix the sluggish connection, call our experts today. We’re always ready to help you.

Endure tech disasters with external support

Three decades ago, the notion of hiring specialists in information technology was virtually unheard of. Nowadays, the majority of businesses are digitally operated, which means technology specialists are a must, especially given the huge increase in different types of security breaches. Determine how external support can back you up in times of technical distress.

Access to new technologies and industry experts

Managed Services Providers (MSPs) are equipped with resources most small businesses can’t afford. They employ teams of experts in fields ranging from cybersecurity to data management to networking — all available for you on an outsourced basis. For example, an MSP provides advanced security software and applications that can help your business avoid the risks of cyberthreat.

They also work with industry tech leaders who provide insights into upcoming hardware and software products in the market. This ensures you receive updated recommendations on the latest technologies so you can use them in your business, and they often come with deals and discounts that you wouldn’t normally have access to.

Knowledge from past breaches

External IT support providers have been helping businesses recover from all kinds of tech disasters since the dawn of hackers. They now have enough knowledge to prepare Data Backup and Disaster Recovery plans for you. This way, you and your team would still be up and running after suffering from an IT emergency without disrupting much of your business operations.

External support providers’ experience with data protection will ensure your systems are monitored around the clock so your security systems are always functioning properly to keep cybercriminals at bay.

Run your business with ease

You don’t specialize in technology, so you don’t have the skill or the experience in dealing with digital felons. You also know how vulnerable your business is online and won’t dare do anything to jeopardize it. That’s why external support is such a great asset — you’ll be able to manage your business without any worries because your external IT provider will keep it protected.

In the end, you also have to be cautious in your search for an external support provider. Conduct your research thoroughly, read through all their testimonial pages, and verify whether their business objectives coincide with yours. To put your mind at ease and to make sure that your business’s technology is in good hands, you can always send us a message and we’ll provide you all the references you need.

How to speed up Windows 10 updates

Keeping up with Windows 10 updates is absolutely critical if you want the latest features and security fixes on your computers. However, the updates can take hours, especially when a major new feature is being released. Fortunately, there are a few things you can do to speed things up.

Why do updates take so long to install?
Windows 10 updates take a while to complete because Microsoft is constantly adding larger files and features to them. For instance, the latest Fall Creators update, which made plenty of adjustments to Cortana, Photos, and Edge, can take upwards of four hours to install. And it takes even longer if you have a fragmented or nearly filled hard drive.

In addition to the large files and numerous features included in Windows 10 updates, internet speed can significantly affect installation times. This is especially true if your network is being overburdened by multiple people downloading the update at the same time.

If multiple downloads aren’t being attempted and you still experience slowness, then either some broken software components are preventing the installation from running smoothly, or apps and drivers that run upon startup are likely to blame.

When you experience any of these issues, try the following:

Free up storage space and defragment your hard drive
Because many Windows 10 updates take up a lot of space in your hard drive, you need to leave enough room for them. This means deleting files and uninstalling software you no longer need.

You’ll also want to defragment your hard drive, a process that organizes data on your hard drive so it can read and write files faster. While this may sound complicated, it’s actually as easy as pressing the Windows button and typing Defragment and Optimize Drives. From there, just select the hard drive, click Analyze, and if the drive is more than 10% fragmented, press Optimize.

Run Windows Update Troubleshooter
If broken software components are causing installation problems, this tool might be able to fix the issue and decrease download and install times.

Disable startup software
Before your update begins, you should also disable third-party applications that can potentially cause disruptions. To do this, press the Windows button again and type msconfig. In the System Configuration Window, go to Services, click Hide all Microsoft services, then click Disable all. Afterwards, access Task Manager (press Ctrl + Alt + Delete) and disable any startup program that might interfere with updates like an Adobe app or printer software.

Optimize your network
Sometimes a faster connection is all you need. Consider switching to fiber optic cables or purchasing more bandwidth from your internet service provider. It’s also a good idea to use bandwidth management tools to make sure enough network resources are reserved for things like Windows 10 updates, not bandwidth hogs like Skype or YouTube.

Schedule updates for low-traffic periods
In some cases, however, you may have to accept the fact that certain updates do take a long time. So instead of installing them during the day, schedule them for after hours when you’re not using your computers. Simply go to Settings and specify when you prefer updates to be installed.
