New MacOS Malware - “RustyAttr”

Beware of RustyAttr: A New Malware Threat for macOS Users

At MacForce, we’re dedicated to keeping your Mac safe, secure, and running at its best. Recently, cybersecurity researchers uncovered a new malware targeting macOS users, named RustyAttr, which uses clever tactics to sneak onto computers. Here’s what you need to know, how it could affect your Mac, and how we can help protect you.

What Is RustyAttr?

RustyAttr is a type of malware that hides in plain sight by exploiting a unique feature in macOS called extended attributes (EAs). These are hidden bits of metadata attached to files and folders. Hackers use these attributes to store malicious code, making it hard for antivirus tools to detect the threat.

How Does It Infect Your Mac?

The malware tricks users into downloading it by bundling itself with decoy PDF files, often containing content about cryptocurrency investments. When the infected file is opened:

1. The app displays an error message or a seemingly harmless PDF to distract you.

2. In the background, the malware executes its harmful code stored in those hidden file attributes.

RustyAttr uses advanced technologies like the Tauri framework (a mix of web and Rust programming tools) to make its attacks even harder to detect.

What Might You Experience?

If your Mac is infected with RustyAttr or similar malware, you might notice symptoms such as:

• Strange error messages when opening files or apps.

• Unusual slowness or crashes.

• A sudden increase in ads or pop-ups.

• Suspicious activity in accounts related to cryptocurrency or finances.

Who Is at Risk?

This malware is believed to be connected to the North Korean hacking group Lazarus, known for targeting cryptocurrency users. While everyone should be cautious, those involved in cryptocurrency investments or finance-related activities are at higher risk.

How to Protect Yourself

Here are a few tips to stay safe:

• Avoid Suspicious Downloads: Be cautious when downloading applications, especially related to cryptocurrency or finance.

• Update Regularly: Keep your macOS and security software up to date to block known threats.

• Think Before You Click: Don’t open unexpected PDFs or files from unknown sources.
