July 16, 2025 - Google has deployed an AI-powered system called 'Big Sleep' to identify and neutralise dormant web domains exploited for cyberattacks. The tool analyses domain behaviour patterns to detect suspicious changes, such as sudden spikes in traffic or unexpected content hosting, which often signal phishing or malware distribution. This proactive approach aims to prevent digital abuse before attacks occur.
Technical implementation involves machine learning models trained on historical domain activity data. 'Big Sleep addresses a critical vulnerability in internet infrastructure,' explained a Google security engineer, noting that dormant domains are frequently repurposed for malicious activities. The system operates in real-time, flagging domains for takedown through partnerships with registrars and hosting providers.
Broader context highlights the escalating arms race between cybercriminals and AI-driven security solutions. As attackers increasingly leverage AI for sophisticated threats, defenders like Google are countering with predictive systems. This aligns with global efforts to enhance cybersecurity through proactive AI monitoring.
Our view: While Big Sleep demonstrates AI's potential in threat prevention, its effectiveness depends on continuous model updates and ethical data usage. Balancing security with privacy remains essential as automated systems gain authority over digital infrastructure.
