hello team
could you please help me with below

If I run the search below, I was expecting to see all malicious user emails reported by GTI. However, I’m not seeing any results, even when querying data from the past year.

I am able to retrieve some malicious IPs when using entity_type = "IP_ADDRESS", but the count is relatively low (around 50). I was expecting a significantly larger number of results.

while working on an another secops instance i was not even about to query globalcontext on search

Has anyone experienced something similar or can confirm whether this behavior is


could you please help me here as i am looking to match for email artifacts with gcti like ip , domain , sender email , hash etc

if i need to match all user email from proofpoint on demand with gcti reported malicious emails  is this the correct way

NL prompt
graph.metadata.source_type = "ENTITY_CONTEXT", extract date from collection_timestamp, count by date, entity type and vendor, 

YARA query
 

graph.metadata.source_type = "ENTITY_CONTEXT"

$date_day = timestamp.get_date(graph.metadata.collected_timestamp.seconds)

match:

$date_day, graph.metadata.entity_type, graph.metadata.vendor_name

outcome:

$count = count(graph.metadata.product_entity_id)




Then you can start visualising / further filtering
