What is Scareware? Don’t Fall Victim to This Online Threat

Avatar Andrea Abbondanza , 02 Jul, 2024

Scareware is a prevalent threat that employs scaremongering tactics to deceive users. These malicious programs are designed to frighten users into believing their devices have been infected with malware.

By exploiting fear, the attackers aim to trick users into purchasing unnecessary software or revealing personal information.

Understanding how scareware operates is crucial for staying safe online and avoiding these deceptive tricks. Let’s explore scareware and learn how to protect your device from these malicious attacks!

What is Scareware?

Living up to its name, scareware is a social engineering tactic designed to scare users into downloading malware-infected software or paying for fake software and exposing personal information. 

Typically, this attack alerts users of a ‘virus’ detection and offers a solution by prompting them to download or purchase a fake application to remove the virus.

Based on its technique, this attack uses a combination of spoofing and social engineering, like phishing.

How Does Scareware Work?

Commonly, scareware is spread through phishing emails or pop-up ads that lead users to visit a malware-infested website.

The emails or pop-up ads are specifically designed to appear legitimate, often incorporating company logos like Google or Windows.

For example, ‘Windows Defender’ might send you an email with ‘A virus has been detected. Take action now!’ or a pop-up ad with a similar tone.

The scaremongering agenda is followed by a solution to ‘remove the virus’, instructing you to click the link to their fake-solution website. Once you comply, you will be redirected to their scam website and asked to insert your credit card information to purchase their fake application.

Sometimes, the software doesn’t even exist. Other times, it does, but it only serves to slow down your device without doing anything useful. In the worst cases, the software is the malware itself.

Scareware vs Ransomware

What Is Ransomware

Scareware and ransomware are both malicious software, but they operate differently and have distinct goals.

Scareware uses fear to trick users into downloading fake software.

For example, you might see a pop-up ad claiming your device is infected with viruses. The ad urges you to download certain scareware programs to fix the issue. However, this program is either useless or harmful, slowing down your device or stealing your information.

Ransomware, on the other hand, is more aggressive. It locks your files or entire system and demands a ransom to unlock them.

For instance, you might receive an email with an attachment that, once opened, encrypts your files. The attacker then demands payment to restore access.

Unlike scareware, ransomware directly holds your data hostage.

Here are some form examples of scareware attacks:

Fake Tech Support

Scammers often start with a pop-up message claiming your computer is infected. The message urges you to call a “tech support” number from real companies like Microsoft.

When you call, the scammer pretends to be a technician and convinces you to grant remote access to your computer. While pretending to fix the issue, they may install malicious software or steal personal information.

Law Enforcement Scams

Scareware mimics official warnings from police or government agencies. You might see a message claiming illegal activity has been detected on your device, and you have to pay a fine to avoid prosecution.

Fake Virus Scams

This classic scareware scam trick involves scareware pop-up ads or alerts claiming your device is infected with a virus, urging you to download a specific antivirus program to remove the threat.

However, the recommended program is either useless or harmful. It may slow down your device, steal personal information, or demand payment for fake services.

Malvertising

It involves embedding malicious code in online advertisements. When you click on the ad, it redirects you to a fake website that claims your device is infected. The site then prompts you to download a program to fix the issue.
