Cybercriminals are getting sneakier — and in 2025, one of the fastest-growing scams we’re seeing is the use of fake system or browser update pop-ups. These scams are engineered to look like legitimate alerts from your operating system or browser, urging users to “update” software that isn’t actually out of date.

How it works:

You’re browsing a legitimate website when suddenly a message pops up:

“Your browser is out of date. Click here to install the latest version.”

It looks convincing. It might even include official-looking icons or branding. But instead of installing a helpful update, clicking the button launches malware — often remote access tools (RATs) or data stealers — that can:

• Give attackers full access to your files

• Capture your passwords and screen activity

• Even activate your webcam or microphone

Why These Attacks Work

These pop-ups are well-timed and well-disguised. Cybercriminals use malvertising (malicious ads) or compromised websites to deliver the pop-ups, often bypassing basic ad blockers.

How to Stay Safe

At CRC Data Technologies, we’ve seen firsthand how damaging these attacks can be. Here’s how to protect your team and data:

• Never install updates from pop-ups. Always update your software via the official system settings or your trusted IT provider.

• Use DNS filtering and endpoint protection. These tools help block access to known malicious domains before damage is done.

• Train your team. Employees should know what legitimate update prompts look like — and more importantly, what red flags to watch for.

The CRC Data Perspective

If you’re ever unsure about a system prompt, don’t click. Ask your IT team — or better yet, let CRC Data Technologies handle updates securely through our managed IT services.
