FOFA rule returns null about mihari

[ninoseki]

I guess you already have 137.74.131.20 in under the same rule.
You can check it by mihari artifact list "rule.id:575fdb13-c04f-48d2-80a8-c1587e1456a8 AND data:137.74.131.20.
If the command outputs something, my hypothesis is right.

Thanks for your quick reply. Actually the rule was new, as I was testing FOFA queries for the first time. In any case, the command you suggested produced the following:

mihari artifact list "rule.id:575fdb13-c04f-48d2-80a8-c1587e1456a8 AND data:137.74.131.20"
{
  "total": 0,
  "currentPage": 1,
  "pageSize": 10,
  "results": [

  ]
}

I'm unable to reproduce the issue unfortunately.

$ mihari search 575fdb13-c04f-48d2-80a8-c1587e1456a8

No worries. I redeployed the system from scratch and tested it. I get the same null value for FOFA.

When I use the same query for censys in the same rule, it works fine. So, there's deff something wrong with FOFA on my side.

Here is the summary:
FOFA query: server=="web.go" && asn="44477" -> returns null + no results
Censys query: services:(services.http.response.headers.Server:web.go) and (autonomous_system.description="STARK-INDUSTRIES")
