Frequently Asked Questions
Product Information & Threat Details
What is MacStealer and how does it operate?
MacStealer is a macOS-based stealer malware identified by the Uptycs threat intelligence team. It targets Catalina and subsequent macOS versions running on Intel M1 and M2 CPUs. The malware extracts documents, browser cookies, and login information, and can collect passwords, cookies, and credit card data from Firefox, Google Chrome, and Brave browsers. It also extracts various file types and the KeyChain database, then exfiltrates the data to a command-and-control server and Telegram channels after tricking users with a fake password prompt.
Which macOS versions are affected by MacStealer?
MacStealer affects macOS Catalina and all subsequent versions, including those running on Intel M1 and M2 CPUs.
What types of data does MacStealer target?
MacStealer targets passwords, cookies, and credit card data from Firefox, Google Chrome, and Brave browsers. It also extracts files such as .txt, .doc, .pdf, .xls, .jpg, .png, .csv, .zip, .rar, .py, .db, and the KeyChain database (base64 encoded).
How does MacStealer exfiltrate stolen data?
After collecting data, MacStealer compresses it into a ZIP file and sends it to a command-and-control (C2) server via a POST request using a Python User-Agent. It also transmits selected information to Telegram channels and deletes the data from the victim's system during a mop-up operation.
What techniques does MacStealer use to trick users?
MacStealer uses a fake password prompt that mimics a system dialog, asking users to enter their credentials with a message like "MacOS wants to access the System Preferences." This social engineering tactic is designed to steal user passwords.
How is MacStealer distributed?
MacStealer is distributed as a .DMG file. Once executed, it opens a fake password prompt and begins its data collection and exfiltration process.
What is the role of Telegram in MacStealer's operation?
After exfiltrating data to the C2 server, MacStealer also transmits selected information to specific Telegram channels and shares the compiled ZIP file with a threat actor's personal Telegram bot.
