Whether they’re attending regular work meetings or catching up with extended family across the globe, many people leverage video conferencing to better connect with others – a process that will likely continue as our world only becomes more digital. But as the rapid adoption of video conferencing tools and apps occurs, potential threats to online safety emerge.
Agora is one of these tools for connection. The company’s video conferencing software is included in apps like MeetMe, Skout, Nimo TV, temi, Dr. First Backline, and Talkspace, across more than 1.7 billion devices globally. According to McAfee Advanced Threat Research (ATR), Agora’s video software development kit (SDK) until recently included a vulnerability that could have allowed an attacker to spy on ongoing video and audio calls.
In accordance with McAfee’s safe vulnerability disclosure policy, ATR provided Agora with details of its thorough research into the issue so that the software developer could take action to address it with a software update.
But let’s take a look at what a vulnerability like this could mean for users.
So, how exactly could this vulnerability allow others to spy on private calls?
The McAfee ATR team discovered that the Agora vulnerability stemmed from an error of incomplete encryption – the process of converting information or data into seemingly random output to prevent unauthorized access. Agora’s SDK implementation did not allow applications to securely configure the setup of video/audio encryption, thereby leaving a potential for hackers to snoop on them.
Therefore, if exploited, this particular vulnerability could’ve allowed a criminal to launch man-in-the-middle attacks, which occur when a hacker secretly intercepts and possibly alters the communications between two unsuspecting users. Aka, they could spy on users’ private video calls.
The vulnerability discovery and mitigation cooperation between McAfee and Agora illustrates why it’s so important for threat researchers to work closely and constructively with app developers to make our digital lives as safe as possible.
As a consumer, however, it’s important to realize what exactly you’re getting into when downloading applications for video conferencing and other tools that help you stay connected.
While the security community encourages developers to write software code with security in mind, software apps tend to struggle with bugs and vulnerabilities in their early days. Consumers should by all means download and enjoy the hottest new apps, but they should also take steps to protect themselves from any undiscovered issues that might threaten them.
Here are a few tips that can help ensure your safety while connecting with others online:
It’s easy to click “Install later” when software updates pop up on your screen. However, these updates often come with security patches for vulnerabilities like the ones mentioned above. To ensure that your software and apps have the latest security fixes, update them immediately or select the option update automatically if available.
Until a patch is created, you should operate under the assumption that a hacker could compromise your video calls. Avoid using vulnerable apps until developers make a software security update available to help protect your calls from being infiltrated.
In order to protect yourself and your loved ones from potential risks, make sure you have a holistic security solution in place, such as McAfee Total Protection, which can help block risky downloads with McAfee WebAdvisor, protect you from malicious mobile apps, and help update Windows and your apps all in one place with Vulnerability Scanner.

The reality is beginning to hit: The holiday season will look and feel different this year. Traditional family gatherings, complete with mile-long dinner tables and flag football games, are now considered COVID “super spreader” events, putting a dent in plans for large gatherings.
Still, there’s a bright side. We may be dealing with a pandemic, but we also happen to live in time of amazing technology and ingenuity. That means when the face-to-face connection isn’t possible, we can connect with a click or two.
According to the Center for Disease Control, it’s important to keep basic safety protocols such as mask-wearing, disinfecting, and social distancing in place. In addition, they recommend limiting the number of guests, celebrating outdoors if possible, and limiting the number of people in food prep areas. One of the most important things you can do, says the CDC, is to “have conversations with guests ahead of time to set expectations for celebrating together.”
A part of those conversations can also include ways to digitally connect with elderly or at risk loved ones who can’t gather and how to do it safely and securely. Here are a few ideas to get you rolling.
One big tip in organizing a successful, digitally connected holiday is to prep your technology logistics before your gathering. Ensure everyone invited to the call has downloaded the right app, adjusted privacy settings, and understands app and safety basics. For family members who may be uncomfortable connecting digitally, consider calling a few days ahead of time, previewing the app, and answering any questions. Prepping your tech will maximize your time together and ensure everyone feels confident.
1. Cook together. Use video apps such as FaceTime or Zoom to share recipes and even have grandma teach the kids to cook her famous corn casserole. Since everyone is together, you may even want to crowdsource favorite family recipes in a google doc and make a family cookbook.
Safe Family Tip: Your FaceTime app is always ideal because it’s encrypted and still private. When using video apps such as Zoom, make sure your account and meeting settings are personal.
2. Share a virtual mealtime. You might be surprised at how much fun sharing a mealtime virtually can be (we’ve tried it!) It’s easy: Set up your phone or computer on a stationary tripod or shelf that frames your dinner table. Agree on a time with family members. Dial them up on your phone or in your app. Toast the holiday in real-time.
Safe Family Tip: Be aware that with the increase in people going online to connect with family, shop, and work, hackers are also working overtime to get into Zoom (and other apps) conversations and figure out ways to plant malware. With increased digital activity, think about a comprehensive security solution, which can help protect devices against malware, phishing attacks, and other threats.
3. Enjoy movie time together. Using apps like Hulu Watch Party, Watch2gether, Amazon Watch, Netflix Party, and Houseparty makes it easy to watch a movie together from multiple locations. For kids, there’s Disney Plus Party for kid-friendly group viewing. Some of the apps require screen sharing, others separate logins, while others are simply one account holder sharing a link. The Verge offers this step-by-step on how to for several of these apps.
Safe Family Tip: Make sure the movie site or app you are using is legal and safe. Cybercriminals are hot on the trail of movie fans and have created movie apps designed to download malware onto computers. Avoid clicking on pop-up ads or random links while looking for movies or apps. Add an extra layer of protection using a Virtual Private Network (VPN) to encrypt your online activity, keep your identity secure, and secure downloads.
4. Multiplayer Game Apps. Don’t worry. Family game night lives on! Even if you are separated by miles, you can play virtual family games like Charades, Uno, Pictionary, Trivia, and many video games.
Safe Family Tip: Be sure the app you are downloading is legitimate. Read reviews and make sure there aren’t any virus or malware issues before downloading. Once downloaded, maximize your safety settings on the app, use strong passwords, and only connect with known players.
5. Virtual Karaoke. Gather on apps like Smule to enjoy some family karaoke together.
Safe Family Tip: Any group app can be a danger zone for cyberbullying or connection from strangers. Be sure that family members are aware of the dangers of allowing younger users to keep these apps on their phones following the holidays. Parental Control Software is an easy way to make sure your kids engage with safe content online.
Thanks to technology, it’s possible to shrink just about any distance. Will it take effort? Sure. Some learning? Yup. But hopefully, even though your home may feel a little more empty this year, your heart will be full.

The COVID-19 pandemic, along with social distancing, has done many things to alter our lives. But in one respect it has merely accelerated a process begun many years ago. We were all spending more and more time online before the virus struck. But now, forced to work, study and socialize at home, the online digital world has become absolutely essential to our communications — and video conferencing apps have become our “face-to-face” window on the world.
The problem is that as users flock to these services, the bad guys are also lying in wait — to disrupt or eavesdrop on our chats, spread malware, and steal our data. Zoom’s problems have perhaps been the most widely publicized, because of its quickly rising popularity, but it’s not the only platform whose users have been potentially at risk. Cisco’s WebEx and Microsoft Teams have also had issues; while other platforms, such as Houseparty, are intrinsically less secure (almost by design for their target audience, as the name suggests).
Let’s take a look at some of the key threats out there and how you can stay safe while video conferencing.
Depending on the platform (designed for work or play) and the use case (business or personal), there are various opportunities for the online attacker to join and disrupt or eavesdrop on video conferencing calls. The latter is especially dangerous if you’re discussing sensitive business information.
Malicious hackers may also look to deliver malware via chats or shared files to take control of your computer, or to steal your passwords and sensitive personal and financial information. In a business context, they could even try to hijack your video conferencing account to impersonate you, in a bid to steal info from or defraud your colleagues or company.
The bad guys may also be able to take advantage of the fact that your home PCs and devices are less well-secured than those at work or school—and that you may be more distracted at home and less alert to potential threats.
To accomplish their goals, malicious hackers can leverage various techniques at their disposal. These can include:

Zoom has in many ways become the victim of its own success. With daily meeting participants soaring from 10 million in December last year to 200 million by March 2020, all eyes have been focused on the platform. Unfortunately, that also includes hackers. Zoom has been hit by a number of security and privacy issues over the past several months, which include “Zoombombing” (meetings disrupted by uninvited guests), misleading encryption claims, a waiting room vulnerability, credential theft and data collection leaks, and fake Zoom installers. To be fair to Zoom, it has responded quickly to these issues, realigning its development priorities to fix the security and privacy issues discovered by its intensive use.
And Zoom isn’t alone. Earlier in the year, Cisco Systems had its own problem with WebEx, its widely-used enterprise video conferencing system, when it discovered a flaw in the platform that could allow a remote, unauthenticated attacker to enter a password-protected video conferencing meeting. All an attacker needed was the meeting ID and a WebEx mobile app for iOS or Android, and they could have barged in on a meeting, no authentication necessary. Cisco quickly moved to fix the high-severity vulnerability, but other flaws (also now fixed) have cropped up in WebEx’s history, including one that could enable a remote attacker to send a forged request to the system’s server.
More recently, Microsoft Teams joined the ranks of leading business videoconferencing platforms with potentially deadly vulnerabilities. On April 27 it surfaced that for at least three weeks (from the end of February till the middle of March), a malicious GIF could have stolen user data from Teams accounts, possibly across an entire company. The vulnerability was patched on April 20—but it’s a reminder to potential video conferencing users that even leading systems such as Zoom, WebEx, and Teams aren’t fool-proof and require periodic vulnerability and security fixes to keep them safe and secure. This is compounded during the COVID-19 pandemic when workers are working from home and connecting to their company’s network and systems via possibly unsecure home networks and devices.
So how do you choose the best, most secure, video conferencing software for your work-at-home needs? There are many solutions on the market today. In fact, the choice can be dizzying. Some simply enable video or audio meetings/calls, while others also allow for sharing and saving of documents and notes. Some are only appropriate for one-on-one connections or small groups, while others can scale to thousands.
In short, you’ll need to choose the video conferencing solution most appropriate to your needs, while checking if it meets a minimum set of security standards for working at home. This set of criteria should include end-to-end encryption, automatic and frequent security updates, the use of auto-generated meeting IDs and strong access controls, a program for managing vulnerabilities, and last but not least, good privacy practices by the company.
Some video conferencing options alongside Zoom, WebEx, and Teams include:

Whatever video conferencing platform you use, it’s important to bear in mind that cyber-criminals will always be looking to take advantage of any security gaps they can find — in the tool itself or your use of it. So how do you secure your video conferencing apps? Some tips listed here are Zoom-specific, but consider their equivalents in other platforms as general best-practice tips. Depending on the use case, you might choose to not enable some of the options here.
