SEC-UNK-B1F655 is an inferred behavioral cluster in the Mothlight observatory. A search-engine crawler that indexes pages for a search index. This profile describes observed requests and classification evidence, not the intent of every visitor sharing a signature.
No. Confidence measures support for the assigned label (out of 100). AI likelihood estimates evidence for AI involvement (out of 100). Identity verification is reported separately.
SEC-UNK-B1F655Confidence and AI likelihood are scores out of 100, not shares of traffic. Percentages elsewhere on this page state their denominator in the section text.
A search-engine crawler that indexes pages for a search index.
Label: SEC · Inferred cluster (grouped by shared client signature; not a proven person or organisation).
Verification: Spoofed identity — this actor claimed a known identity, but the claim failed verification. A claimed identity is not a verified identity.
Spoofed claim: the user-agent or claim suggested a known service, but network evidence did not support it. Treat the name as a claim, not an attribution.

Requests only `/robots.txt` with GET from 7 sources; no exploitation attempts; consistent with uptime or metrics scraping.
Based on 8 requests from 7 distinct sources. Buckets with fewer than 3 events or 2 sources are hidden. IPs are never listed here; user agents are shown only as product families. Percentages in breakdowns use the publishable buckets shown as their denominator.
Window adapts to available data since first seen; empty early periods are trimmed and labelled, not stretched across a 30-day axis.

Services / traps targeted: robots (7 of 7 publishable trap observations).
No publishable technique tags yet.
No publishable CVE observations yet. This does not mean the actor never probed a vulnerability; only that no bucket reached the publication threshold.
Robots compliance: Not measured yet for this actor.
Canary follows: 0 publishable canary follows
Honeytoken uses: 0 publishable honeytoken uses
Following a canary or using a honeytoken is behavioural evidence; it does not by itself prove AI involvement or intent.
No related bots above the similarity threshold.
No publishable related actors yet. Related actors are publishable bots sharing a known-bot identity, cluster label, or technique set; withheld single-source actors are not listed here.
