Nova Stealer, also known as MioLab, is a macOS information stealer that has been active since at least November 2025. It is promoted through ClickFix-style social engineering, including curl-based payloads that induce users to execute commands on their systems. The operation offers customized builds and maintains supporting backend infrastructure. Its operator has publicly indicated plans to expand the malware with macOS remote-access and botnet functionality, but those capabilities are not established as deployed features.
