It indicates that domains hosted under this ASN exhibit behavioral patterns statistically associated with malicious activity, such as unstable activation cycles, suspicious hosting characteristics, or combinations of weak reputation indicators.
Three questions every analyst asks before acting on this signal.
It indicates that domains hosted under this ASN exhibit behavioral patterns statistically associated with malicious activity, such as unstable activation cycles, suspicious hosting characteristics, or combinations of weak reputation indicators.
Repeated risky behavior across multiple domains within the same ASN suggests systemic abuse tolerance or lack of governance, increasing the likelihood that the ASN is being used to support malicious operations.
This is a supporting malicious signal. It does not confirm malicious intent alone, but it amplifies suspicion when correlated with stronger indicators like blacklist hits, malware distribution patterns or high-risk TLD usage.
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.
