What is the problem?
Some hackers are sending fake group chat requests on Microsoft Teams, a popular online platform for communication and collaboration. They pretend to be someone from your team or domain and ask you to join a chat. If you accept, they will trick you into downloading a file that looks like a PDF document, but it is actually a harmful program that can steal your data and damage your computer. This program is called DarkGate malware, and it can bypass your security software and access your browser information and other platforms like Discord.
Why should you care?
Microsoft Teams has about 280 million users every month, so it is a big target for hackers who want to spread DarkGate malware. If you or your employees fall for their fake chat requests, you could lose your sensitive information, such as passwords, bank accounts, or customer data. This could harm your reputation, your finances, and your legal obligations. You could also face other problems, such as ransomware, which is a type of malware that locks your files and demands money to unlock them.
How can you prevent it?
The best way to protect your business from this threat is to educate yourself and your employees on how to spot and avoid phishing emails and messages. Phishing is a technique that hackers use to trick you into clicking on malicious links or attachments. Here are some tips to help you recognize and prevent phishing:
- Check the sender’s email address and name carefully. If they look suspicious or unfamiliar, do not open or reply to their messages.
- Look for spelling and grammar mistakes, or strange or urgent language in the message. These are signs that the message is not legitimate.
- Do not click on any links or attachments in the message, unless you are sure they are safe and relevant. If you are not sure, contact the sender by phone or another channel to verify.
- Use a reliable antivirus software and keep it updated. This can help you detect and remove malware from your computer.
- Conduct regular training and exercises for your employees on how to identify and avoid phishing. This can help you improve your security awareness and reduce the risk of falling victim to hackers.
- Ensure your data is backed up, including data stored in Microsoft SharePoint or OneDrive.
