What does the new malware do?
The new malware is called MacStealer, and it is capable of stealing sensitive data stored in iCloud Keychains, including passwords and credit card information. How these hackers are spreading the malware is still unknown, however, it is likely being spread on fake websites or sent via phishing emails. All that is known is that the malware appears as a DMG file.
A variety of Mac browsers are being attacked, including Google Chrome, Mozilla Firefox and Brave. However, the malware can also harvest Microsoft Office files, images, archives and Python scripts from infected Macs.
ALWAYS DO THIS FIRST BEFORE DOWNLOADING A SOFTWARE UPDATE TO YOUR PHONE
Once MacStealer infects a Mac device, it opens a fake password prompt for users trying to gain access to their System Settings app. Instead of granting access to the app, the malware begins harvesting the user’s credentials. It then sends the stolen data back to a command and control server operated by the hackers distributing this malware by using the encrypted messaging app Telegram.
A hacking forum, where the MacStealer creators have been regularly discussing the malware, has revealed that the cybercriminals want to add even more new features, including the ability to capture data from Apple’s Safari browser and its Notes app.
