Hackers Are Now Sending Malware Through Microsoft Teams at Work

What Just Happened

Cybercriminals have found a new way to attack people at work. A hacking group called UNC6692 is sending malicious software directly through Microsoft Teams chat messages. This isn't a phishing link you can avoid clicking. It's actual malware being delivered through a platform millions of people trust every day for work, school, and even family communication.

The Details

Microsoft Teams has become a daily tool for remote workers, students, and hybrid teams. Most people consider it safe because it's made by Microsoft and managed by their workplace IT departments. That trust is exactly what hackers are exploiting.

Here's how the attack works. Criminals send what looks like a normal Teams message to employees. The message contains malware disguised as something legitimate, like a work file or document. Because it comes through Teams rather than email, it bypasses many security systems that companies use to protect their networks. People are also less suspicious of Teams messages because they assume only coworkers and approved contacts can reach them.

The malware these hackers are using is custom built. That means it's specifically designed to avoid detection by common antivirus software. Once installed on a computer, it can steal passwords, access company files, or even spread to other devices on the same network.

Who Is Affected

Anyone who uses Microsoft Teams for work is potentially at risk. This includes remote workers, office employees, and hybrid workers who split time between home and office. If your family members use Teams daily, they could receive one of these malicious messages.

Schools and universities using Teams are also targets. Students, teachers, and administrators who trust messages from their educational network could accidentally download malware. The risk extends to home networks too. If someone opens malware on their work laptop while connected to home WiFi, it could spread to other family devices.

What You Should Do Right Now

1. Talk to family members who use Teams for work or school. Ask them to be suspicious of unexpected file attachments, even from people they know. Accounts get compromised, and hackers impersonate trusted contacts.

The Bigger Picture

This attack represents a troubling shift in cybercrime tactics. Hackers are moving away from traditional email phishing toward trusted workplace tools. As families increasingly blend work and home technology, these professional security threats become household problems. Staying informed about emerging attack methods protects not just your job, but your entire family's digital safety.
