Key drivers
Request size anomaly
Requests are unusually large or shaped in a way that suggests abuse or automation.
request_size
Hits 89
Points 20.59
User-Agent anomaly
User-Agent signals look missing, inconsistent, or indicative of non-browser tooling.
ua
Hits 284
Points 20.45
Scan velocity
High request rate and broad endpoint coverage suggest scanning or automated enumeration.
scan_velocity
Hits 26
Points 16.38
Automated client behavior
Traffic patterns strongly suggest automation rather than a human-operated browser.
