Hi Sebastian,

Thanks for a quick response. It appears the IPv6 "sibling" of the feed, i.e. the event6_sinkhole_http_referer also needs the same small change of field names (extra.http_referer_ip -> source.ip). I haven't made a thorough check, so I'm not sure if these are the only ones.

Br, Mika

Hi Mika

I agree with you. As per IntelMQ's guidelines/documentation (https://docs.intelmq.org/latest/user/event/#meaning-of-source-and-destinatio...) the data we care about is always in the source part, and the IP address in source.ip.

Jason, can you please adapt the mapping?

best regards Sebastian

We received one sinkhole http referer event that got flagged as not belonging to our constituency. At a closer look, it turned out that intelmq's destination.ip field (see event4_sinkhole_http_referer in https://github.com/The-Shadowserver-Foundation/report_schema/blob/main/intel...https://github.com/The-Shadowserver-Foundation/report_schema/blob/main/intelmq.json) contains the IP the malware tried to access (?) and then the IP of the machine possibly infected by the malware ended up in extra.http_referer_ip. Everything fine and coherent with the feed's documentation, no complaints.

To deduce to whom in our constituency an event belongs, we have a bot that first looks at the source.ip field and if this does not match, then we try the destination.ip field. This heuristic works fine with all feeds but in the above case it fails.

Is there a chance the report field http_referer_ip gets mapped one day in intelmq.json to intelmq's source.ip field (like in the majority of other feeds) instead of extra.http_referer_ip? Just asking since I'd like to keep things simpler and avoid work-arounds.

Br, Mika
