How to remove NimDoor from macOS

What kind of malware NimDoor?

NimDoor is a type of malware that targets macOS systems, especially in Web3 and crypto organizations. It uses advanced techniques like encrypted settings, asynchronous execution, and a distinctive way to stay hidden and persistent. It is notable for using Nim programming language components, making it a sophisticated and stealthy threat.

NimDoor overview

NimDoor malware works by placing two main files into the infected computer's temporary folder. The first file, made with C++, runs a hidden program that sends stolen data back to the attackers. The second file helps the malware stay on the system by setting up a LaunchAgent and adding more malicious files, so it can keep control over the Mac for a long time.

NimDoor's data theft capabilities are extensive, targeting sensitive information such as browser data, Keychain credentials, shell history files, and Telegram data. The targeted browsers include Arc, Brave, Firefox, Google Chrome, and Microsoft Edge. The data that NimDoor grabs from Telegram included encrypted local database and the special key needed to unlock it.

NimDoor can also steal credentials stored in the macOS Keychain, which holds passwords and sensitive information. By accessing these credentials, the malware gives attackers a way to gain unauthorized access to accounts and services.

Additionally, NimDoor can steal shell history files, which on macOS are records of commands a user has typed into the Terminal. These files can reveal sensitive information like commands used to access servers, run scripts, or manage files.

Conclusion

NimDoor is a highly advanced and stealthy macOS malware. Its sophisticated techniques for persistence, data theft, and evasion make it a serious threat. Users and organizations should remain cautious and use strong security measures to protect against such threats.

More examples of malware targeting macOS are CryptoBot, VShell, and SNOWLIGHT.

How did NimDoor infiltrate my computer?

The attack begins with social engineering techniques, where attackers impersonate trusted contacts on Telegram to convince victims to schedule a meeting via Calendly. Victims then receive an email containing a Zoom meeting link and instructions to run a fraudulent "Zoom SDK update" script. Executing this script initiates the malware infection process.

How to avoid installation of potentially unwanted applications?

Exercise caution with emails from unfamiliar sources, and if a message appears unexpected or suspicious, avoid clicking links or opening attachments. Only obtain software from official websites or app stores to ensure safety. Avoid pirated programs, key generators, and related tools.

Additionally, avoid engaging with pop-ups, advertisements, and dubious links on untrustworthy websites, and never agree to receive notifications if these sites request to send them. Keep your operating system and applications up to date, and regularly scan your device using trusted antivirus or security software to maintain protection.

If your computer is already infected, we recommend running a scan with Combo Cleaner Antivirus for Windows to automatically eliminate all threats.
