Quick mental math challenge: How many Apple Watches can you buy with $118 billion dollars? If you guessed around 296 million watches congrats, you’re smarter than the writer of this blog! We had to use a calculator. The point is that’s the predicted size of the US wearable market by 2028 according to a recent report. That means for as much wearable tech as we have in our lives already, even more, is on the way.
If you own a piece of wearable tech it’s easy to understand why it’s so popular. After all, it can track our fitness, provide contextual help in daily life, and, in the case of hearing aids, even do cool things like sync with Bluetooth. As VR and AR gains a foothold who knows what other incredible tech might be headed our way by 2028? However wearable tech also comes with certain risks. The most prominent: cybercriminals potentially gaining access to your data.
The weakest link in the wearables space is your mobile phone, not the actual wearable device itself. That’s because wearables tend to link to your mobile device over a short-range wireless spectrum known as “Bluetooth.” This spectrum is used to send and receive data between your wearable device and your mobile. That makes your mobile a prime target for hackers.
Most commonly, hackers gain access to the data on your mobile through malware-laden apps. These apps are oftentimes designed to look like popular apps, but with enough differences that they don’t flag copyright suspicion.
Hackers can use these malicious apps to do a variety of things from making phone calls without your permission, sending and receiving texts, and extracting personal information—all potentially without your knowledge. They can also, with the help of your wearable, track your location through GPS and record any health issues you’ve entered into your wearable. The point is: once they have permissions to your mobile device, they have a lot of control and a lot of resources.
The hacker can then use this data to conduct varying forms of fraud. Need a special prescription from your doctor that happens to sell well on the black market? Well, so does the hacker. Going out for a jog in the morning? Good information for a burglar to know. These personal details just scratch the surface of information available for the taking on your mobile devices.
These types of threats aren’t limited to wearables, however. The Internet of Things—the phenomenon of devices connected to the Internet for analysis and optimization—encompasses all sorts of other electronic devices such as washing machines and refrigerators that can put your data at risk as well. But these life-changing devices can be secured through education and industry standards. Two things we’re working on day and night.
Of course, securing the weakest link in your wearables environment, your phone will go a long way towards keeping your data safe. But what happens when your computer, where you store backups of your smartphone, is compromised too? We’ve got you covered with McAfee LiveSafe service, our comprehensive security solution that provides protection for your entire online life.

Imagine you’re driving down a highway to get to work. There are other cars on the road, but by and large everyone is moving smoothly at a crisp, legal speed limit. Then, as you approach an entry ramp, more cars join. And then more, and more, and more until all of the sudden traffic has slowed to a crawl. This illustrates a DDoS attack.
DDoS stands for Distributed Denial of Service, and it’s a method where cybercriminals flood a network with so much malicious traffic that it cannot operate or communicate as it normally would. This causes the site’s normal traffic, also known as legitimate packets, to come to a halt. DDoS is a simple, effective and powerful technique that’s fueled by insecure devices and poor digital habits. Luckily, with a few easy tweaks to your everyday habits, you can safeguard your personal devices against DDoS attacks.
The expansion of 5G, proliferation of IoT and smart devices, and shift of more industries moving their operations online have presented new opportunities for DDoS attacks. Cybercriminals are taking advantage, and 2020 saw two of the largest DDoS offensives ever recorded. In 2020, ambitious attacks were launched on Amazon and Google. There is no target too big for cybercriminals.
DDoS attacks are one of the more troubling areas in cybersecurity, because they’re incredibly difficult to prevent and mitigate.. Preventing these attacks is particularly difficult because malicious traffic isn’t coming from a single source. There are an estimated 12.5 million devices that are vulnerable to being recruited by a DDoS attacker.
DDoS attacks are fairly simple to create. All it takes are two devices that coordinate to send fake traffic to a server or website. That’s it. Your laptop and your phone, for example, could be programmed to form their own DDoS network (sometimes referred to as a botnet, more below). However, even if two devices dedicate all of their processing power in an attack, it still isn’t enough to take down a website or server. Hundreds and thousands of coordinated devices are required to take down an entire service provider.
To amass a network of that size, cybercriminals create what’s known as a “botnet,” a network of compromised devices that coordinate to achieve a particular task. Botnets don’t always have to be used in a DDoS attack, nor does a DDoS have to have a botnet to work, but more often than not they go together like Bonnie and Clyde. Cybercriminals create botnets through fairly typical means: tricking people into downloading malicious files and spreading malware.
But malware isn’t the only means of recruiting devices. Because a good deal of companies and consumers practice poor password habits, malicious actors can scan the internet for connected devices with known factory credentials or easy-to-guess passwords (“password,” for example). Once logged in, cybercriminals can easily infect and recruit the device into their cyber army.
These recruited cyber armies can lie dormant until they’re given orders. This is where a specialized server called a command and control server (typically abbreviated as a “C2”) comes into play. When instructed, cybercriminals will order a C2 server to issue instructions to compromised devices. Those devices will then use a portion of their processing power to send fake traffic to a targeted server or website and, voila! That’s how a DDoS attack is launched.
DDoS attacks are usually successful because of their distributed nature, and the difficulty in discerning between legitimate users and fake traffic. They do not, however, constitute a breach. This is because DDoS attacks overwhelm a target to knock it offline — not to steal from it. Usually DDoS attacks will be deployed as a means of retaliation against a company or service, often for political reasons. Sometimes, however, cybercriminals will use DDoS attacks as a smokescreen for more serious compromises that may eventually lead to a full-blown breach.
DDoS attacks are only possible because devices can be easily compromised. Here are three ways you can prevent your devices from participating in a DDoS attack:
Now that you know what a DDoS attack is and how to protect against it, you’re better equipped to keep your personal devices and safe and secure.
