How to eliminate Tiny FUD from computers
Written by Tomas Meskauskas on (updated)
What kind of malware is Tiny FUD?
Tiny FUD is a Trojan that targets macOS users. The term FUD (Fully Undetectable) implies that the malware is built to avoid detection by antivirus and other security tools. It tricks security software by changing process names, using DYLD injection, and running commands from a command-and-control server.
Tiny FUD overview
One of the methods Tiny FUD uses is process name manipulation. It means that the Trojan disguises its processes to appear like normal, legitimate system processes. This makes it difficult for security software to spot anything unusual/suspicious. Also, the malware employs DYLD injection, a method that interferes with how macOS loads certain libraries and allows to hide its presence from monitoring tools like the Activity Monitor.
The malware also connects to a remote command-and-control (C2) server, allowing attackers to execute commands on the infected computer remotely. This remote access allows cybercriminals to control the computer, steal sensitive data, or perform other malicious actions without the user's knowledge.
Another capability of Tiny FUD is to capture screenshots. This means that the malware can take snapshots of what is displayed on the user's screen without their knowledge. Such screenshots can reveal sensitive information like login credentials, personal messages, financial details, and more.
This functionality enables the attacker to have real-time insights into the victim's activities. Generally, the malware's capabilities may lead to privacy breaches, financial losses, identity theft, and other issues. Therefore, Tiny FUD should be eliminated from compromised systems as soon as possible.

Its stealthy design makes it particularly dangerous, as it can bypass traditional security measures and continue to execute harmful tasks on the victim’s system.
More examples of malware targeting macOS are PondRAT, HZ RAT, and TodoSwift.
How did malware infiltrate my computer?
Cybercriminals spread malware through various methods. Pretty often, they send deceptive emails with malicious attachments or links, exploit software vulnerabilities, use malvertising (malicious ads), hide malware in pirated software (or cracking tools and keygens), or deliver malware using tech support scams.
Users may also be tricked into infecting their computers through compromised USB drives, malicious or compromised websites, or files and programs obtained through P2P networks, third-party downloaders, free file hosting services (even legitimate ones), and similar sources.
How to avoid malware infections?
Before interacting with an email, check if it is legitimate and its content is safe. Avoid opening links or attachments in unsolicited or suspicious emails from unknown addresses. Only download software from official web pages or trusted app stores. Never download pirated software, and avoid interacting with pop-ups, ads, or links from shady websites.
Also, do not grant permission to show notifications to untrustworthy pages. Keep your software up to date and perform regular system scans with a reputable security tool to stay protected against threats. If your computer is already infected, we recommend running a scan with Combo Cleaner Antivirus for macOS to automatically eliminate all threats.
