As Microsoft Teams continues to make communication easier between organizations, it’s now common to receive chat messages from people outside your company — whether they’re clients, vendors, or partners.
That flexibility is convenient, but it also opens a new door for cyber attackers. Recently, scammers have started exploiting Teams’ external chat feature to send malicious links and files through what look like legitimate chat requests.
This type of scam is called a click-lure attack, and it’s quickly becoming one of the newest tactics used to breach businesses.
At Felix IT Solutions, we’re dedicated to helping organizations stay protected across every communication platform — including Microsoft Teams.
🕵️♂️ What Is a Click-Lure Attack?
A click-lure attack starts with a simple Teams chat request. The message often appears to come from a professional, partner company, or even an internal department.
The attacker’s goal? To make you click before you think.
Here are some common examples of what these messages might say:
- “Can you quickly review this?”
- “Here is the document you asked for.”
- “Join this call now, it’s urgent.”
Once the victim clicks a malicious link or opens an infected file, malware can be installed — or the attacker can capture login credentials. From there, they can gain access to company systems, confidential files, or internal chats.
🚩 Red Flags to Watch For
It’s not always easy to spot a scam, but these red flags are common in click-lure attacks:
| Suspicious Behavior | What It Usually Means |
|---|---|
| You don’t recognize the person or company | Attempt to impersonate a legitimate contact |
| Urgency or pressure in the message | Designed to make you react quickly |
| Unexpected links or attachments | Possible malware or phishing |
| Vague or unclear purpose | No legitimate business reason for contact |
| Free or generic email domains | Common disguise tactic |
If something feels “off”, it probably is. Trust your instincts.
🛡 How to Protect Yourself
Here are a few simple but powerful steps every employee should follow to stay safe on Microsoft Teams:
- Don’t click links or open attachments from unknown or unexpected senders.
- Verify the sender’s identity through another communication channel — like email or a phone call.
- Never share passwords, MFA codes, or sensitive internal files over Teams chat.
- Use the Block and Report feature in Teams if you suspect a scam.
- When in doubt, stop and reach out to Felix IT Support for help.
A few seconds of caution can prevent hours — or even days — of recovery time.
