How Stegano Malware Targets Millions of Unaware Internet Explorer Users

Learn about Stegano malware, a dangerous threat to Internet Explorer users. This malicious software spreads through popular websites and infects users’ computers, stealing sensitive information and leaving backdoors. Discover how the malware works and how to protect yourself.

What is Stegano Malware?

Stegano Malware is a type of malicious software that has been targeting millions of unaware Internet Explorer users through popular websites. The scariest part is that it manages to go unnoticed for two years before anyone can spot it. This malware spreads through infected ads that appear on major news sites, leading to a high number of infections.

How does Stegano Malware work?

The attack starts with infected JavaScript ads for a screenshot app called “Broxu” and a privacy tool called “Browser defense”. These ads are then delivered to larger ad networks and subsequently appear on major news sites. When the infected ad appears on your computer, Stegano scans, extracts, and runs code that exploits a known vulnerability in Internet Explorer. Once it confirms that your environment is vulnerable, Stegano loads a one-pixel iframe off-screen that redirects you to their landing page.

On the landing page, a file capable of exploiting three different Flash vulnerabilities is loaded. The malware then displays a special GIF file containing cached data, which can be identified by a QR-like code that is not noticeable to the naked eye. Finally, it runs a security check that scans for any security software. If the scan doesn’t detect anything that could expose you, the malware launches the payload, leaving infected machines with a backdoor, keylogger, screenshot maker, and video maker.

How to Protect Yourself from Stegano Malware?

Since Stegano relies on Internet Explorer and Flash to function, the simplest precaution is to avoid both. Researchers suggest that malware can be avoided with fully patched software and an up-to-date and reliable Internet security solution.
