ZuRu is a highly dangerous macOS backdoor trojan specifically designed to target developers and IT professionals. It disguises itself as legitimate applications like Termius, iTerm2, SecureCRT, Navicat, and Microsoft Remote Desktop. Once installed, ZuRu silently embeds a post‑exploitation framework that enables full remote control, data exfiltration, and system persistence.

How ZuRu Mac Malware Infects Systems
How I Got Infected
ZuRu infections usually begin when a user downloads a seemingly legitimate macOS utility from an unofficial or malicious source. These applications appear functional but carry hidden components designed to initiate the malware installation.
The malware is typically packed inside a .dmg disk image containing both the real app and hidden malicious binaries. When opened, these background processes silently launch and initiate contact with a remote command-and-control (C2) server.
What Does It Do
Once active, ZuRu establishes persistence on the system using a LaunchDaemon with an Apple-like name to avoid detection. It then deploys a powerful Khepri-based post-exploitation beacon which allows attackers to:
- Upload and download files
- Perform detailed system reconnaissance
- Execute terminal commands remotely
- Inject and control processes
- Maintain persistence and perform updates via MD5 checksum validation
The malware continuously communicates with remote C2 domains to receive attacker instructions and update its payload.
Should You Be Worried for Your System?
Yes. ZuRu is a stealthy and powerful threat. It does not display any obvious symptoms, making it ideal for long-term spying and exploitation. Its ability to impersonate trusted developer tools increases the likelihood of users unknowingly installing it. Anyone who has recently downloaded developer utilities from unknown sources is strongly advised to run a full system scan.
