That "Teams update" email might not be what you think.
A busy user. A familiar-looking page. One click.
That's all it took. What appeared to be a routine Microsoft Teams update was actually a phishing page delivering a malicious installer. The page looked completely legitimate - right font, right layout, right branding.
This is exactly how these attacks work. They don't rely on obvious red flags. They rely on you being in a hurry - and it's getting worse.
In some cases, what gets installed isn't just malware. It's a remote monitoring and management tool - software that's normally used by IT support teams to access and manage computers remotely. Legitimate businesses like mine use it every day to help clients fix problems without having to come on-site. In criminal hands, it's a skeleton key to your device.
Once it's installed, the attacker can see your screen, move your mouse, open files, steal passwords, and move deeper into your network - all while you carry on with your day none the wiser. No dramatic warning. No obvious sign anything is wrong.
A few things worth knowing:
Microsoft will never push Teams updates through an email link or a pop-up asking you to download something. Teams updates itself silently in the background. If an email or webpage is asking you to click a link or download a file to "update Teams" - stop.
The same applies to driver updates. Fake driver update prompts are one of the oldest tricks going and they're still catching people out every day.
If you're a Black Swan client, you don't need to act on prompts like this. We manage your updates. If something genuinely needs attention on your device, we'll be in touch directly. When in doubt, ignore it and drop us a message.
If you use Teams at work, please share this post. If you manage a team of people - brief them this week.
The attack didn't need to be sophisticated. It just needed someone to be busy.
