It indicates that the domain was registered very recently — within the last week, month, or few months. Newly registered domains are frequently used in phishing, malware campaigns, and command-and-control infrastructures.
Three questions every analyst asks before acting on this signal.
It indicates that the domain was registered very recently — within the last week, month, or few months. Newly registered domains are frequently used in phishing, malware campaigns, and command-and-control infrastructures.
Threat actors often use short-lived domains to avoid blacklisting and to quickly deploy malicious payloads. These domains are rarely associated with legitimate long-term business operations.
Shorter registration windows (e.g., within the last week or month) indicate significantly higher risk. Domains registered within the past year still require close monitoring, especially if combined with other suspicious indicators such as free SSL certificates or abnormal DNS patterns.
A realistic shape of the entry the engine appends to the risk_signals array when this signal fires. Evidence keys are subgroup-default; per-signal overrides documented in the API reference.
