Sensitive file probing

Syndu annotates all incoming traffic and extracts behavioral signals that help explain intent. This page defines the sfp signal — what it means, how to interpret it, and how it will later connect to live evidence across IPs, subnets, organizations, ISPs, countries, and cities.

Signal gist Requests target commonly sensitive files, configs, backups, or administrative resources.

Sensitive file probing
How to read this signal
This annotator represents a behavioral pattern, not a claim of identity. It’s designed to help you understand why certain traffic looks suspicious, automated, probing, or exploit-oriented — and to support consistent reporting across the Syndu system.
Explanation
Flags attempts to access files and paths that are commonly sensitive or frequently exposed by mistake (configuration files, environment files, backups, admin panels, hidden resources). This annotator is especially useful for explaining opportunistic scanning behavior. In reports, show targeted resources grouped by category and the observed outcomes (404/403/200) without implying compromise.

Live sections

These panels will be wired to real metrics, enrichment context, and drill-down links.
Signal footprint over time
Rolling volume, bursts, first/last seen, and time-window slices (e.g. last hour/day/week). This will help separate chronic background noise from active campaigns.

Top affected entities
Links to the entities where sfp is most present: IPs, subnets, organizations/ASNs, ISPs, and geographies — with “why” context.
Coming next: entity leaderboards + drill-down
Enrichment context
How enrichment affects interpretation: known crawlers, monitored ranges, trusted scanners, or policy exceptions. This is where “benign but noisy” gets separated from “unknown and risky.”
