What does the new malware do?
The new malware is called MacStealer and is capable of stealing sensitive data stored in iCloud keychains, including passwords and credit card information. How these hackers spread the malware is not yet known, but it is most likely distributed through fake websites or via phishing emails. All that is known is that the malware looks like a DMG file.
Various Mac browsers are being attacked, including Google Chrome, Mozilla Firefox, and Brave. However, malware can also collect Microsoft Office files, images, archives, and Python scripts from infected Macs.

Here’s what you need to know about MacStealer malware and how to keep your Mac safe. (Cyberguy.com)
Once MacStealer infects a Mac device, it exposes a fake password for users trying to access their System Preferences app. Instead of granting access to the app, the malware starts collecting user credentials. It then sends the stolen data back to a command and control server run by hackers who distribute this malware using the Telegram encrypted messaging app.
A hacker forum where MacStealer creators regularly discuss malware shows that cybercriminals want to add even more new features, including the ability to hijack data from Apple’s Safari browser and its Notes app.
