Messaging apps are a common form of digital communication these days, with Facebook’s WhatsApp being one of the most popular options out there. The communication platform boasts over 1.5 billion users – who now need to immediately update the app due to a new security threat. In fact, WhatsApp just announced a recently discovered security vulnerability that exposes both iOS and Android devices to malicious spyware.
So, how does this cyberthreat work, exactly? Leveraging the new WhatsApp bug, cybercriminals first begin the scheme by calling an innocent user via the app. Regardless of whether the user picks up or not, the attacker can use that phone call to infect the device with malicious spyware. From there, crooks can snoop around the user’s device, likely without the victim’s knowledge.
Fortunately, WhatsApp has already issued a patch that solves for the problem – which means users will fix the bug if they update their app immediately. But that doesn’t mean users shouldn’t still keep security top of mind now and in the future when it comes to messaging apps and the crucial data they contain. With that said, here are a few security steps to follow:
- Flip on automatic updates. No matter the type of application or platform, it’s always crucial to keep your software up-to-date, as fixes for vulnerabilities are usually included in each new version. Turning on automatic updates will ensure that you are always equipped with the latest security patches.
- Be selective about what information you share. When chatting with fellow users on WhatsApp and other messaging platforms, it’s important you’re always careful of sharing personal data. Never exchange financial information or crucial personal details over the app, as they can possibly be stolen in the chance your device does become compromised with spyware or other malware.
- Protect your mobile phones from spyware. To help prevent your device from becoming compromised by malicious software, such as this WhatsApp spyware, be sure to add an extra layer of security to it by leveraging a mobile security solution. With McAfee Mobile Security being available for both iOS and Android, devices of all types will remain protected from cyberthreats.

Yes, you should update WhatsApp.
But not for the reasons they’re telling you.
Users have shared the private photos stored in their email and social networks with Ever – not realising that they were being used to feed a facial recognition system.
Logging onto a free Wi-Fi network can be tempting, especially when you’re out running errands or waiting to catch a flight at the airport. But this could have serious cybersecurity consequences. One popular Android app, which allowed anyone to search for nearby Wi-Fi networks, was recently left exposed, leaving a database containing over 2 million network passwords unprotected.
How exactly were these passwords exposed? The app, which had been downloaded by millions of users, allowed anyone to search for Wi-Fi networks in their area. The app also lets users upload their Wi-Fi network passwords from their devices to its database for others to use. When the database was left exposed and unprotected, anyone could access and download its contents. Each record in the database contained the Wi-Fi network name, its precise geolocation, its basic service set identifier, and the network password in plaintext. Because the app didn’t require users to obtain permission from the network owner, it would be quite easy for a cybercriminal to modify router settings and point unsuspecting users to malicious websites. What’s more, a threat actor could also read unencrypted traffic that goes across a wireless network, allowing them to steal passwords and private data.
Thankfully, the web host was able to take down the database containing the Wi-Fi passwords within a day of being notified. But it’s important for users to be aware of the cybersecurity implications that free or public Wi-Fi presents. Check out the following tips to help protect your data:
- Change your Wi-Fi password. If you think your password may have been affected by this exposure, err on the side of caution and reset it. Be sure to make your new password complex and unique.
- Keep your network password private. Wi-Fi networks could be susceptible to a number of threats if their passwords are left in the wrong hands. Only share your passwords with family, friends, and those you trust, and never upload your password to a public database for strangers to use.
- Safeguard your online privacy. Use a security solution like McAfee Safe Connect to encrypt your online activity, protect your privacy by hiding your IP address, and better defend against cybercriminals.

Like most parents, before you go to sleep each night, you take extra care to lock doors and windows to keep your family safe from any outside threats. The only thing you may have overlooked is the smartphone illuminated on your nightstand. And if you were to add up the smartphones humming all over your house, suddenly you’d have a number of unlocked doors that a determined criminal could enter through. Maybe not tonight — but eventually.
Over time you’ve purchased and plugged in devices throughout your home. You might have a voice assistant, a baby monitor, a thermostat, a treadmill, a gaming system, a fitness watch, smart TVs, a refrigerator, and many other fun, useful gadgets. Each purchase likely connects to your smartphone. Take stock: You now have a digital ecosystem growing all around you. And while you rarely stop to take notice of this invisible power grid around you, hackers can’t stop thinking about it.
This digital framework that pulsates within your home gives cybercriminals potential new entryways into your life and your data. Depending on your devices, by accessing your smartphone, outsiders may be able to unlock your literal doors while you are away (via your home security system), eavesdrop on your family conversations and collect important information (via your voice assistant), access financial information (via your gaming system, tablet, or laptop).
What you can do:
- Change factory security settings. Before you fire up that smart TV, drone, or sound system, be sure to change each product’s factory settings and replace it with a bulletproof password to put a layer of protection between you and would-be hackers.
- Protect your home network. We are connected people living in connected homes. So, part of the wired lifestyle is taking the lead on doing all we can to protect it. One way to do that is at the router level with built-in network security, which can help secure your connected devices.
- Stay on top of software updates. Cybercrooks rely on consumers to ignore software updates; it makes their job so much easier. So be sure to install updates to your devices, security software, and IoT products when alerted to do so.
Smartphone = Front Gate
The most common entry point to all of these connected things is your smartphone. While you’ve done a lot of things to protect your phone — a lock screen, secure passwords on accounts, and system updates — there are hacking tactics you likely know nothing about. According to McAfee’s recent Mobile Threat Report, you don’t know because the scope and complexity of mobile hacks are increasing at alarming rates.
The latest statistics report that the average person has between 60-90 apps installed on their phones. Multiply that between all the users in your home, and you are looking at anywhere from 200-500 apps living under your digital roof. Hackers gravitate toward digital trends. They go where the most people congregate because that’s where they can grab the most money. Many of us control everything in our homes from our apps, so app downloads are off the charts, which is why crooks have engineered some of their most sophisticated schemes specifically around app users.
Hidden apps are a way that crooks trick users into letting them inside their phones. Typically, hidden apps (such as TimpDoor) get to users via Google Play when they download games or customized tools. TimpDoor will then directly communicate with users via a text with a link to a voice message that gives detailed instructions to enable apps from unknown sources. That link downloads malware which will run in the background after the app closes. Users often forget they’ve downloaded this and go on with life while the malware runs in the background and can access other internal networks on the smartphone.
What you can do:
- Stay alert. Don’t fall for the traps or click links to other apps sent via text message.
- Stay legit. Only download apps hosted by the original trusted stores and verified partner sites.
- Avoid spam. Don’t click on any email links, pop-ups, or direct messages that include suspicious links, password prompts, or fake attachments. Delete and block spam emails and texts.
- Disable and delete. If you are not using an app, disable it. And, as a safety habit, remove apps from your phone, tablet, or laptop you no longer use.
Again, crooks go where the most people congregate, and this year it is the 60 million+ downloaded game Fortnite. The Fortnite craze has lead hackers to design fake Fortnite apps masquerading as the real thing. The fraudulent app designers go to great lengths to make the download look legitimate. They offer enticing downloads and promise users a ton of free perks and add ons. Once users download the fake app, crooks can collect money through ads, send text messages with more bad app links, crypto jack users, or install malware or spyware.
What you can do:
- Don’t install apps from unknown sources. Not all gaming companies distribute via Google Play or the App Store. This makes it even harder for users to know that the app they are downloading is legit. Do all you can to verify the legitimacy of the site you are downloading from.
- Delete suspicious acting apps. If you download an app and it begins to request access to anything outside of its service, delete it immediately from your device.
- Update devices regularly. Keep new bugs and threats at bay by updating your devices automatically.
- Monitor bank statements. Check statements regularly to monitor the activity of the card linked to your Fortnite account. If you notice repeat or multiple transactions from your account or see charges that you don’t recognize, alert your bank immediately.
- Be a savvy app user. Verify an app’s legitimacy. Read other user reviews and be discerning before you download anything. This practice also applies to partner sites that sell game hacks, credits, patches, or virtual assets players use to gain rank within a game. Beware of “free” downloads and avoid illegal file-sharing sites. Free downloads can be hotbeds for malware. Stick with the safer, paid options from a reputable source.

The incidents of cyber-attacks on smartphones, especially those working on the popular Android operating system, have been on a constant rise. However, a major reason people still continue to go in for android smartphones, is the fact that these are mostly cheap to buy. However, the year 2018 ended with…

Free apps have a lot of appeal for users. They don’t cost a cent and can help users complete tasks on-the-go. However, users should take precautions before installing any app on their device. Researchers here at McAfee have observed some Android apps using extremely deceptive techniques to try and trick users into signing up for a very expensive service plan to use basic tool functionalities like voice recording and opening zip files.
The two apps being called into question, “Voice recorder free” and “Zip File Reader,” have been downloaded over 600,000 times combined. So at first glance, users may assume that these are reputable apps. Once installed, they offer the user an option to use a “Free trial” or to “Pay now.” If the user selects the trial version, they are presented with a subscription page to enter their credit card details for when the three-day trial is over. However, these apps charge a ridiculously high amount once the trial is up. “Voice recorder free” charges a whopping $242 a month and “Zip File Reader” charges $160 a week.
Users who have downloaded these apps and then deleted them after their free trial may be surprised to know that uninstalling the app will not cancel the subscription, so they could still be charged these astronomical amounts for weeks without realizing it. While this is not technically illegal, it is a deceptive tactic that app developers are using to try to make an easy profit off of consumers who might forget to cancel their free trial.
With that said, there are a few things users can do to avoid becoming victim to deceptive schemes such as these in the future. Here are some tips to keep in mind when it comes to downloading free apps:
- Be vigilant and read app reviews. Even if an app has a lot of downloads, make sure to comb through all of the reviews and read up before downloading anything to your device.
- Read the fine print. If you decide to install an app with a free trial, make sure you understand what fees you will be charged if you keep the subscription.
- Remember to cancel your subscription. If you find a reputable free app that you’ve researched and want to use for a trial period, remember to cancel the subscription before uninstalling the app off your device. Instructions on canceling, pausing, and changing a subscription can be found on Google Play’s Help page.

In 2018, Google Play Protect made Android devices running Google Play some of the most secure smartphones available, scanning over 50 billion apps everyday for harmful behaviour.
Android devices can genuinely improve people's lives through our accessibility features, Google Assistant, digital wellbeing, Family Link, and more — but we can only do this if they are safe and secure enough to earn users' long term trust. This is Google Play Protect's charter and we're encouraged by this past year's advancements.
Google Play Protect, a refresherGoogle Play Protect is the technology we use to ensure that any device shipping with the Google Play Store is secured against potentially harmful applications (PHA). It is made up of a giant backend scanning engine to aid our analysts in sourcing and vetting applications made available on the Play Store, and built-in protection that scans apps on users' devices, immobilizing PHA and warning users.
This technology protects over 2 billion devices in the Android ecosystem every day.
What's newOn by default
We strongly believe that security should be a built-in feature of every device, not something a user needs to find and enable. When security features function at their best, most users do not need to be aware of them. To this end, we are pleased to announce that Google Play Protect is now enabled by default to secure all new devices, right out of the box. The user is notified that Google Play Protect is running, and has the option to turn it off whenever desired.
New and rare apps
Android is deployed in many diverse ways across many different users. We know that the ecosystem would not be as powerful and vibrant as it is today without an equally diverse array of apps to choose from. But installing new apps, especially from unknown sources, can carry risk.
Last year we launched a new feature that notifies users when they are installing new or rare apps that are rarely installed in the ecosystem. In these scenarios, the feature shows a warning, giving users pause to consider whether they want to trust this app, and advising them to take additional care and check the source of installation. Once Google has fully analyzed the app and determined that it is not harmful, the notification will no longer display. In 2018, this warning showed around 100,000 times per day
Context is everything: warning users on launch
It's easy to misunderstand alerts when presented out of context. We're trained to click through notifications without reading them and get back to what we were doing as quickly as possible. We know that providing timely and context-sensitive alerts to users is critical for them to be of value. We recently enabled a security feature first introduced in Android Oreo which warns users when they are about to launch a potentially harmful app on their device.
This new warning dialog provides in-context information about which app the user is about to launch, why we think it may be harmful and what might happen if they open the app. We also provide clear guidance on what to do next. These in-context dialogs ensure users are protected even if they accidentally missed an alert.
Google Play Protect has long been able to disable the most harmful categories of apps on users devices automatically, providing robust protection where we believe harm will be done.
In 2018, we extended this coverage to apps installed from Play that were later found to have violated Google Play's policies, e.g. on privacy, deceptive behavior or content. These apps have been suspended and removed from the Google Play Store.
This does not remove the app from user device, but it does notify the user and prevents them from opening the app accidentally. The notification gives the option to remove the app entirely.
Keeping the Android ecosystem secure is no easy task, but we firmly believe that Google Play Protect is an important security layer that's used to protect users devices and their data while maintaining the freedom, diversity and openness that makes Android, well, Android.
