Definition ∞ A Stealth Attack describes a clandestine security breach or exploit designed to remain undetected for an extended duration. The objective is often to exfiltrate data, maintain persistent access, or gradually compromise system integrity without alerting defenders. These attacks often leverage sophisticated techniques to evade detection systems and blend with normal network traffic.
Context ∞ In the context of decentralized systems and digital assets, a stealth attack presents a severe threat, often leading to substantial losses before discovery, as reported in crypto news. The decentralized nature of blockchain can make detection more challenging, as there may not be a central point of monitoring. Early detection and robust security protocols are paramount to prevent prolonged exploitation and protect user funds from such insidious threats.
