New Cyber Threat Alert: Fake Update Pop-ups Are on the Rise
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.
