Thank you for your comment.
The discrepancy should be due to the data sources that are used to populate BRON:
- When you deploy BRON locally you download data from the data sources.
- The public version of BRON currently only updates the data sources with intermittent frequency
- The data sources used in BRON are constantly updated with different frequencies, e.g. CVEs are reported more often than ATT&CK tactics
We will check the update frequency of the public BRON instance
from bron.
If that was the case, the local deployment should have returned more CVEs then.
But it returns less.
Am i missing something?

Hmm, let me rebuild my local BRON to see if I can replicate it
from bron.
Thanks for your help.
I run this query:
LET target = ["CVE-2020-0681", "CVE-2020-0885","CVE-2019-0698", "CVE-2019-0726","CVE-2023-38408","CVE-2020-14145","CVE-2022-20724","CVE-2021-34699","CVE-2008-4963"]
FOR c IN cve
FOR target_element IN target
Filter c.original_id==target_element
FOR cw IN CweCve
FOR cwee in cwe
FOR each_capec IN CapecCwe
FOR cp in capec
FOR tc IN TechniqueCapec
FOR t in technique
Filter cw._to == c._id
AND cw._from==cwee._id
AND each_capec._to==cw._from
AND each_capec._from==cp._id
AND tc._to == each_capec._from
AND tc._from == t._id
COLLECT cveid=c.original_id,
cd = c.metadata.description,
cweid=cwee.original_id,
cwe_n=cwee.name,
capecid = cp.original_id,
capec_n=cp.name,
ttpid = t.original_id,
ttn = t.name
SORT cveid DESC
RETURN {
cve_id: cveid,
cve_description: cd,
cwe_id : cweid,
cwe_name : cwe_n,
capec_id : capecid,
capec_name : capec_n,
technique_id: ttpid,
technique_name: ttn
}
from bron.
I also just saw that the local implementation has 314,886 edges while the public version has 33,382,276.
Also the collection of CWECVE is much much larger (i assume same goes for the rest of the collections)
from bron.
Yes, I see the same now when my local BRON is built. The public BRON might be stale. I am investigating it now.
