Hackers Use Facebook Ads to Spread JSCEAL Malware Through Fake Crypto Apps

Cybercriminals have launched a new campaign using Facebook ads to deliver dangerous malware. These ads promote fake cryptocurrency trading apps, which trick users into downloading JSCEAL—a script-based malware that steals personal data.

How the Scam Works

First, users see fake crypto app ads in their Facebook feed. These ads look official and often copy the branding of real platforms. When someone clicks, they are redirected to a fake website that offers a downloadable app. However, instead of a real trading tool, they get JSCEAL malware.

Once installed, the malware begins to collect:

• Saved login details from browsers
• Cryptocurrency wallet credentials
• Active session data

Then, this information is secretly sent to the attackers.

What Is JSCEAL?

JSCEAL is a malware program written in JavaScript. It runs in the browser and does not need to install extra software. Because it operates quietly and hides its code, many users don’t notice it.

Instead of using large, complex viruses, hackers now prefer these smaller, stealthy scripts. They are faster, harder to detect, and easier to hide in fake tools.

Why Hackers Choose Facebook Ads

Hackers use Facebook ads because they can:

• Reach millions of people
• Target users by interest or behavior
• Appear trustworthy due to Facebook’s design

In many cases, hackers take over real business accounts. They use these accounts to publish fake ads that blend in with normal content. As a result, people are more likely to click.

Recent Similar Threats

This isn’t the first time Facebook ads have been used to spread malware. In the past:

• NodeStealer targeted Facebook ad accounts and credit cards
• Some fake AI apps, such as Kling AI, delivered remote access malware
• Other campaigns used chat plugins to steal browser data

These attacks follow a pattern. Hackers copy trusted tools, post fake ads, and steal user data.

How to Protect Yourself

To stay safe, follow these steps:

• Do not install apps from Facebook ads
• Download tools only from official websites
• Keep your browser and antivirus updated
• Use two-factor login for your accounts
• Regularly check your browser for unwanted extensions

For businesses, it’s important to:

• Monitor who has access to Facebook accounts
• Set up alerts for ad spending or strange activity
• Educate teams about phishing and ad scams
