EXP-UNK-022B4A is an inferred behavioral cluster in the Mothlight observatory. An exploit bot that sends requests designed to trigger a known vulnerability. An attempt is not evidence of compromise. 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.
EXP-UNK-022B4AConfidence and AI likelihood are scores out of 100, not shares of traffic. Percentages elsewhere on this page state their denominator in the section text.
An exploit bot that sends requests designed to trigger a known vulnerability. An attempt is not evidence of compromise.
Label: EXP · Inferred cluster (grouped by shared client signature; not a proven person or organisation).
Verification: Inferred cluster — no vendor identity claim to verify; the label comes from observed behaviour.

Counts for this actor are withheld because all observed requests came from a single source. Behavioural breakdowns are not published until the actor is seen from at least two distinct sources with at least three events.
Volume band: Fewer than 3 requests. Exact counts, paths, and breakdowns stay unpublished for single-source actors. How the publication rule works
Withheld · single source. Technique, service and CVE breakdowns are not published for single-source actors.
Robots compliance: Withheld · single source — not measured for publication.
Canary follows: Withheld or below publication threshold — not a zero. Canary follows are counted only when publishable.
Honeytoken uses: Withheld or below publication threshold — not a zero.
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.
Withheld · single source. Paths are not published for single-source actors.
