What is MacStealer malware

MacStealer is a new type of malicious software that targets macOS versions from Catalina onwards. The malware disguises itself as legitimate software to steal sensitive data like your iCloud Keychain data, passwords, and credit card information from web browsers like Chrome, Firefox, and Brave.

MacStealer malware functions

Victims who run MacStealer’s Trojan horse app unknowingly put their password into a fake macOS system message. The malware then freely collects your system’s data, which is sent to the attacker-controlled web server, like Telegram, for further exploitation.


It also attempts to steal your cookies. While collecting cookies might seem strange, it's important to understand that stealing stay-logged-in cookies gives hackers direct access to your accounts. Well, the good part about the stay-logged-in cookies is that they provide the convenience of remaining logged in to our account indefinitely. However, if malicious actors get these cookies and use them on another computer, they can log in as that user and carry out any action normally accessible with that account.

How does the MacStealer malware infection occur

If you’ve ever asked yourself can websites give your Mac viruses, the answer is yes. And MacStealer is a prime example of the type of malware floating around the web.


The .DMG files that contain the MacStealer malware can be shared through a number of different methods, one of which includes online uploads. Once uploaded, users can be tricked into downloading the file by clicking a link or button disguised to come from a legitimate source.


Currently, MacStealer spreads through a .DMG file named “weed.dmg,” which tricks you into entering your password to permit access to your System Preferences.

MacStealer spreads using a file named “weed.dmg,” tricking users into entering their password to access System Settings.

If successful, MacStealer compresses the stolen data into a ZIP file and sends it to the cybercriminal via a command and control server. To hide its tracks, MacStealer deleted the ZIP file off your device during a system cleanup.

Many cybercriminals are copying existing P2Es and creating fake websites with graphics and text taken directly from the actual P2E’s site. Unsuspecting victims could easily mistake the fake pages for the legitimate game and accidentally click on the malicious link or download the malware file.
