How to Prevent Hacks in Microsoft Teams Meetings

How to Prevent Hacks in Microsoft Teams Meetings

Early in the pandemic, when working from home was novel for many and video conferencing calls were new, zoom-bombing started to become a problem for businesses and schools. There was no telling when a prankster may show up, possibly in a state of undress or spewing obscenities, to ruin a call in progress.

These days, zoom-bombers have more nefarious plans. According to email security provider Avanan, hackers are infiltrating Microsoft Teams meetings and dropping links to malware in the chat. The hackers may be getting into the meetings after compromising email accounts belonging to employees. Avanan, owned by security firm Check Point Software, warns(Opens in a new window) hackers could be stealing login credentials for Microsoft 365 through email phishing campaigns.

Once the hacker gets into a meeting, they drop a malicious executable file masquerading as a legitimate program called "User Centric." If anyone downloads and installs the file, the Trojan program drops malicious DLL files, allowing the hacker to hijack the system from afar.

How can you prevent a hack attempt during your Microsoft Teams video calls? The following three tips will help.

1. Get verbal confirmation.
If someone drops a link into the chat, ask about the link's purpose before you click it. Hackers can impersonate your coworkers by stealing their login credentials, so you can never be too careful about what you download.

2. Install antivirus software and keep it running.
Microsoft Teams has built-in antivirus detection(Opens in a new window) with Microsoft 365, but Avanan claims the scanning has been slow to identify real-time attacks.

3. Protect your logins with a password manager.
Stop using the same login credentials all over the web. Use a password manager to create and store unique and strong passwords for work and personal browsing.

Switching to a New Password Manager

If your password manager doesn’t have all the features you want or need, it’s time to make a switch. Luckily, most password managers offer free trials of their premium tiers, so you can bounce around between services before finding the one that’s right for you.

The best password manager is one that's easy to use, so you don’t go back to storing your credentials on sticky notes, or worse, using the same passwords for every login around the web. Finding your perfect password manager may take some trial and error, but luckily switching is easy.

How to Export and Import Your Current Passwords

If you're ready to switch from one password manager to another, the easiest way is to export your credentials from your current password manager to a file on your computer that you import into your new password manager.

Many services allow you to save the file with the service’s special file name. The service may allow you to export login information such as usernames and passwords via a CSV file, too.

After you’ve saved your old passwords to your computer, install the new password manager. During the setup process, the password manager will ask if you want to import your current password information, which is where your new files come in. Import either the specialized file or the CSV file to the new password manager, and you’re ready to go!
