recon agent hit RDAP rate limit mid-engagement; lookups failed on authoriz

Not specified by the original author.

TL;DR

RDAP servers throttle aggressively, so the agent should act like every lookup costs money: cache every response on disk, deduplicate domains by registrar before querying, and back off when throttled. Most engagements need a fraction of the lookups the agent actually makes.

recon agent hit RDAP rate limit mid-engagement; lookups failed on authorized targets

Use this when

• RDAP lookups for authorized target domains start returning 429s or timeouts partway through enumeration.
• The agent looks up the same domain or IP block multiple times across the run.
• The failure cascade starts at the lookup stage and stalls everything downstream.

Not for this skill when

• The RDAP server refuses the queries entirely (403, invalid responses). That is an access or format problem.
• The engagement has no domain or infrastructure enumeration phase. Then RDAP is irrelevant.
• Lookups succeed but the data is wrong. That is a data-quality problem.

Steps

1. Add a local cache: before any RDAP query, check a JSON cache file keyed by domain or IP; after a successful query, store the response. Verify: the second run of the same target list makes zero RDAP calls.
2. Deduplicate the target list before querying: group domains by registrar and IPs by announced block, and query each group once. Verify: the deduped list is shorter than the raw list.
3. On a 429, back off exponentially with jitter and resume from the cache-aware queue instead of restarting. Verify: a forced throttle in testing pauses the queue rather than failing it.
4. Pace the queue below the server's documented limits with a fixed delay between calls. Verify: a 15-minute test batch completes without a single 429.
5. Log throttled queries with timestamps in the run notes so the tester can see whether the data is complete. Verify: the notes list any domains that never got a successful lookup.

Variant phrasings

RDAP throttling killed recon lookups

Same cache-and-backoff fix.

agent re-queries RDAP for same domains

Deduplication-focused variant.

WHOIS/RDAP rate limit mid-enumeration

Broader phrasing.

Compatibility: any RDAP client or script. The cache file pattern is client-agnostic.

Why it happens

Recon agents expand targets enthusiastically: every subdomain becomes a lookup, every IP becomes a lookup, and the same infrastructure gets queried once per branch of the enumeration tree. RDAP providers rate-limit exactly this pattern. Without a cache the agent pays full price for every duplicate, hits the wall fast, and the whole downstream pipeline stalls on missing data.

Edge cases / pitfalls

• Cached RDAP data goes stale; for long engagements, expire cache entries after a few days rather than trusting them forever.
• Some registries throttle harder than others. Track per-server throttle counts and pace each server separately.
• A domain that never resolves through RDAP is a data gap, not a dead end; note it and move on rather than retrying it into another rate limit.

TL;DR

Fix this in the MISP API in the SOC alert enrichment workflow by acting on the exact message first: queue the MISP calls through one shared limiter, honour the retry delay the API returns, back off exponentially after the first limit response, and cache repeat lookups so the same question or indicator is never fetched twice in one run. Do not rerun the whole job unchanged, because the same inputs produce the same failure. Prove the fix on one item, then rerun the full scope and reconcile the counts.

MISP API rate limit hit mid-SOC alert enrichment workflow error failed quota

Use this when

• The operation in the MISP API in the SOC alert enrichment workflow fails with this exact message: MISP API rate limit hit mid-SOC alert enrichment workflow error failed quota.
• The same failure repeats on retry with unchanged inputs.
• A review, export or check is blocked until this item completes.

Not for this skill when

• The message is a permission or outage notice from the platform. Resolve that first, then return here if this error remains.
• The operation completes and you only disagree with its output. That is a quality review, not this failure.

Steps

1. Reproduce the failure with the smallest scope that still shows it in the MISP API in the SOC alert enrichment workflow, and copy the full message plus the alert, incident or enrichment record involved into the run notes. Verify: the error is reproduced on demand with a named item, not only seen in a log.
2. Apply the specific fix for this error: queue the MISP calls through one shared limiter, honour the retry delay the API returns, back off exponentially after the first limit response, and cache repeat lookups so the same question or indicator is never fetched twice in one run. Verify: a full rerun finishes with no rate limit responses and the call count per run is visibly lower than before.
3. Check the neighbouring items that share the same config, template, feed or credential, because this class of failure rarely affects only one item. Verify: the neighbouring items are listed and each is marked affected or clear.
4. Compare the result counts, decisions or alerts against the source in the MISP API in the SOC alert enrichment workflow so a silent partial success is caught before sign off. Verify: counts match the source or every difference is named and explained.
5. Rerun the original operation in the MISP API in the SOC alert enrichment workflow on the previously failing scope, watching for the same message rather than assuming success from a quiet log. Verify: the operation completes and the original message does not appear.
6. Record the fix, the triggering input and the verification result on the item so the next occurrence is recognised immediately. Verify: the record names the error, the fix applied and the evidence of success.

Why it happens

parallel agent steps called the MISP API at full speed with no shared limiter or cache, so the run consumed the quota in minutes and every later call failed.

Fix this in AbuseIPDB enrichment by acting on the exact message first: cache address results for the rest of the day, batch the checks for an incident into one pass, and reserve quota for high severity alerts by skipping the live check (cache only) for low severity ones.

Why it happens

every alert triggered a fresh live check, so the daily quota was spent early on low value repeats.
