time-of-click url verdict stuck on pending for hours

Not specified by the original author.

TL;DR

A pending verdict that never resolves means the click-time scan queued and lost the job, the link target stalls analysis, or the scanning service is degraded. For the affected user the practical question is whether the destination can be verified another way. Check service health, test the URL in an external scanner, and if it is a needed legitimate link, allow it narrowly rather than leaving users at a dead page.

time-of-click url verdict stuck on pending for hours

Use this when

• A user click lands on a scanning page that stays pending for hours.
• Several unrelated links are stuck pending at the same time, suggesting a service issue.

Not for this skill when

• The verdict resolves after a short wait. That is normal detonation time.
• The link is confirmed malicious in the pending period. Keep it blocked.

Steps

1. Record the exact URL, the time of first click and how many users are affected. Verify: scope is one link or many.
2. Check the mail platform service health for URL scanning degradation during the window. Verify: a service incident is confirmed or ruled out.
3. Analyse the URL in an independent scanner to get a current verdict. Verify: you have a verdict from at least one working source.
4. If the link is verified legitimate and needed, add a time-boxed tenant allow for the exact URL or domain with an owner. Verify: the exception is narrow and dated.
5. Have an affected user click again and confirm resolution, then diary the exception for removal. Verify: access works and the follow-up is scheduled.

Why it happens

Click-time verdicts are computed on demand and cached. A job lost between queue and cache leaves a link in permanent pending, because nothing re-triggers the scan while the cache entry says a verdict is coming.

Edge cases / pitfalls

• Re-sending the message with a fresh copy of the link often resolves a single stuck verdict, since the new copy queues a new scan.
• Mass pending states are almost always service-side. Report them rather than building exceptions.
• Pending is not a clean verdict. User guidance should treat a stuck scan as a stop, not a pass.

TL;DR

Inconclusive is a verdict, not an absence of one: it means the service has no reputation for this URL, which for a fresh phishing link is the expected state. An agent that retries until certainty will loop forever. Define the policy up front: inconclusive plus other risk signals means quarantine and submit for detonation; inconclusive alone means tag, deliver with warning per your risk posture, record for later re-check, and move on. Re-check in a later pass when reputation may have formed.

url-reputation API returned inconclusive mid-triage and the agent's verdict loop failed to converge

Use this when

• The agent repeatedly queries the same URL awaiting a firm verdict.
• Runs end with a batch of URLs in a permanent undecided state.

Not for this skill when

• The API is erroring, not returning inconclusive. Fix the integration error handling.
• The URL is confirmed malicious by another source. Act on that source.

Steps

1. Log the distribution of API verdicts over a run to confirm inconclusive is a stable category in responses. Verify: the inconclusive rate and the affected URLs are known.
2. Write the decision rule for inconclusive into the agent policy, combining at least one more signal such as sender age, first-seen domain or message context. Verify: every inconclusive case now maps to an action.
3. Add a re-check queue: store inconclusive URLs with a timestamp and re-query them in a later run, applying any firmer verdict retroactively. Verify: re-checks happen without blocking the main sweep.
4. Submit persistently inconclusive campaign URLs for detonation to get a behavioural verdict instead. Verify: detonation is the escalation path, not more reputation polls.
5. Run the agent over the stalled batch. Verify: every URL resolves to an action and the run completes.

Variant phrasings

url reputation inconclusive unknown verdict agent policy

The inconclusive policy variant.

agent verdict loop never converges unknown url

The convergence variant.

Compatibility: URL reputation APIs including VirusTotal and gateway feeds, agent decision policies.

Why it happens

Reputation is backward-looking, and phishing URLs are born unknown. An agent designed as if every URL has a knowable score has no move for the most important case, so it stalls in the gap between its design and reality.

Edge cases / pitfalls

• Cap reputation polls per URL per run at one. Anything more is waste disguised as diligence.
• Retroactive verdicts matter: when a re-check turns malicious, purge earlier deliveries automatically.
• Record inconclusive as its own metric. A rising rate often marks a new campaign before any vendor does.

TL;DR

urlscan queues are public and variable: a submission can wait far longer than a triage run can afford, and a report step that blocks on it inherits the whole queue delay. Submit early in the workflow, not at report time, poll with a deadline, and let the report ship with the scan marked pending and a reference, updating the case when the result lands. For urgent verdicts, keep a second analyser as fallback.

urlscan.io submission stuck in queue and the triage agent's report timed out

Use this when

• Reports are delayed hours by one urlscan submission in a pending state.
• The agent run times out at the reporting step.

Not for this skill when

• The submission was rejected as invalid or private. That needs a submission fix, not patience.
• The URL is internal and should never go to a public scanner. Route it to internal analysis instead.

Steps

1. Move submission to the start of URL triage, storing the submission identifier with the case immediately. Verify: submission time no longer sits on the report path.
2. Poll for the result during the run with a deadline; on deadline, mark the scan pending with its reference and continue. Verify: a stuck scan cannot block the run past the deadline.
3. Add a completion watcher that attaches late urlscan results to the case and triggers follow-up if the verdict is malicious. Verify: late results still change outcomes.
4. Configure a fallback: if a verdict is needed urgently, submit to the sandbox detonation you control in parallel. Verify: urgent items have two independent paths.
5. Run a report cycle during a busy scanner period. Verify: the report ships on time with pending scans clearly marked.

Variant phrasings

urlscan submission pending report timeout agent

The pending submission variant.

triage report blocked waiting external scanner fallback

The fallback variant.

Compatibility: urlscan.io submission and result APIs, agent report workflows.

Why it happens

Public scanning services are shared infrastructure with shared queues. Treating one as a synchronous dependency couples your incident timeline to strangers traffic, which is worst exactly during big campaigns when everyone submits at once.

Edge cases / pitfalls

• Never submit URLs containing live session parameters or internal addresses to public scanners. They publish results.
• A scan reference URL is itself evidence; include it in the case even when the verdict is pending.
• Rate your own submissions during campaigns; bulk submissions deepen the queue you are complaining about.
