What Are Pop-Up Scams? Understanding the different types that you may encounter
Pop-up scams are deceptive online advertisements, notifications, or alerts that appear in pop-up windows while you’re browsing the internet. In other words, it is the alerts or notifications that pop up in a little window or dialog box when you are using or opening a browser or an application.
Pop-up scams often look like legitimate messages—claiming your computer has a virus, alerting you of a full storage or memory, offering a free prize, or pretending to be a software update.
These pop-ups are designed to trick you into clicking, downloading files, calling a fake tech support, or entering personal information.
Bad actors use different types of pop-ups to deceive and exploit users. Below is a breakdown of common malicious pop-up types that you may encounter:
1. Scareware/Tech Support Scams:
“Your computer is infected!” pop-ups: These pop-ups display alarming messages claiming that your system is infected with a virus, urging you to call a fake tech support number. The goal is to scare you into paying for unnecessary or harmful services.
“Critical security alert!” pop-ups: Similar to scareware, these pop-ups create a false sense of urgency, often imitating legitimate system warnings. They may prompt you to download security software like anti-virus, which is actually malware.
2. Ransomware pop-ups:
Ransom demands: These pop-ups claim that your files have been encrypted and demand payment (often in cryptocurrency) to restore access. They may use official-looking warnings to scare you into paying the ransom, even if your files haven’t been affected.
This kind of pop-up uses full-screen mode, a disabled close button, constant reappearing, and locking of keyboard/mouse functions tactics to create a strong sense of panic, making victims more likely to follow the demands. This tactic makes it difficult for the user to close the alert.
3. “Storage Full” Pop-ups:
Fake “Storage Full” warnings: These pop-ups claim that your device’s storage is almost full and urge you to click for a solution to clear the storage and increase your space. The goal is to trick you into downloading unnecessary software or malware or subscribing to unwanted services. These often appear on mobile devices but can also target laptop users, playing on the fear of running out of space and losing data.
4. Malware Distribution Pop-ups:
Drive-by downloads: These pop-ups automatically download malware onto your device without your knowledge or permission, exploiting weaknesses in your browser or operating system.
Fake software updates: These pop-ups mimic legitimate software updates, but instead of providing real updates, they install malware on your device.
5. Adware and Redirects:
Excessive and intrusive ads: These pop-ups bombard you with endless ads, often redirecting you to suspicious websites that may be harmful.
Pop-under ads: These open new browser windows behind your current one, making them harder to detect while potentially leading you to dangerous sites.
6. Phishing Pop-ups:
Fake login prompts: These pop-ups mimic login screens for popular websites like banks or social media to steal your credentials. They often appear when you visit compromised or malicious websites.
Prize/survey scams: These pop-ups offer exciting rewards or ask you to participate in surveys. In reality, they’re designed to collect your personal information for malicious purposes.
The danger lies in what happens next. Clicking on a scam pop-up can lead to malware being installed on your device, which hackers can use to steal your data, track your activity, or even gain control of your device.
Even if you close the pop-up, some scams are designed to exploit that action and still cause harm.
Clicking the “close” button on a malicious pop-up can have negative consequences. While it might seem like a quick way to get rid of the annoying window, doing so can actually expose your system to risks.
Why Clicking ‘Close’ on a Pop-Up Scam Could Expose Your Data
Fake “Close” Buttons:
Many malicious pop-ups use fake “close” buttons that don’t actually close the window. Instead of shutting down the pop-up, clicking these buttons might trigger a download of malware, redirect you to a harmful website, or even initiate a phishing scam. What looks like a standard “X” button could be a cleverly disguised link designed to harm your system or steal your data.
JavaScript Exploits:
Malicious pop-ups often use JavaScript code to manipulate browser behavior. Even a simple click on what appears to be a harmless button can activate hidden scripts that compromise your device. These scripts might run in the background, allowing hackers to access your data without your knowledge.
Adware and Tracking:
In some cases, clicking the “close” button might not close the pop-up but instead signal to the attackers that your device is active. This can lead to an increase in intrusive ads, adware installation, or aggressive tracking of your online behavior. Over time, this can slow down your device and compromise your privacy.
Unleashing Ransomware:
In more advanced attacks, clicking “close” might trigger a ransomware installation. This can encrypt your files, making them inaccessible unless you pay a ransom. In some cases, attackers might also use the opportunity to lock down your entire system, demanding payment to release your data.
Opening Multiple Pop-Ups (Pop-up Loop):
Instead of closing the pop-up, clicking the “close” button might trigger a series of additional pop-ups, creating a loop that makes it almost impossible to escape. This overwhelming barrage of windows can slow down or crash your system, making it harder to regain control without restarting your device.
Safer Alternatives: How to Close Malicious Pop-ups Without Risk
1. Use Task Manager (Windows) or Activity Monitor (macOS)
If a pop-up freezes your browser or prevents normal interaction, the best solution is to force-close the browser using your operating system’s tools. This ensures you’re not clicking within the malicious window, reducing the risk of triggering harmful scripts.
- Windows:
- Open Task Manager by pressing Ctrl + Shift + Esc or Ctrl + Alt + Delete and selecting “Task Manager.”
- Locate your browser in the list of running applications.
- Select it and click “End Task” to safely close the browser.
- MacOS:
- Open Activity Monitor by pressing Command + Space to open Spotlight, then type “Activity Monitor” and hit Enter.
- Find your browser in the list, select it, and click the “X” button in the upper-left corner of the Activity Monitor window to force quit.
2. Browser’s Force Quit Option
Many browsers have built-in options to force quit or close the application without interacting with pop-ups. This prevents accidental engagement with malicious content.
- Google Chrome:
- On Windows: Press Alt + F4 to close the active window without clicking within the browser.
- On macOS: Press Command + Q to force close the browser.
- Mozilla Firefox:
- On Windows: Press Ctrl + Shift + Q to quit Firefox entirely.
- On macOS: Press Command + Option + Esc and force quit the application.
- Safari (macOS):
- Press Command + Q to quit Safari quickly without interacting with any pop-up or malicious content.
3. Restart Your Computer
If you encounter a persistent pop-up that locks your browser or prevents you from taking any action, restarting your computer can help regain control. This will reset frozen processes and clear any browser or system issues caused by malicious pop-ups.
On Windows:
- Click the Start button at the bottom-left corner of the screen.
- Select the Power icon, then choose Restart.
- Alternatively, press Ctrl + Alt + Delete, then click the Power icon in the bottom-right corner and select Restart.
If the above options Don’t Work:
- Hold down the Power button on your computer for 5-10 seconds until the computer powers off completely. Then, press the Power button again to restart.
On macOS:
- Click the Apple logo in the top-left corner of your screen.
- Select Restart from the dropdown menu.
- Confirm the restart by clicking Restart.
- Alternatively, press Control + Command + Eject (or Control + Command + Power on newer Macs) to quickly restart your Mac.
If the Above Options Don’t Work:
- Hold down the Power button on your Mac until the system shuts down completely. Afterward, press the Power button again to restart.
What to Do After Closing a Malicious Pop-Up
Closing a malicious pop-up is just the first step. To ensure your system and personal information remain safe, follow these critical steps:
