Good morning guys,
I'm using the INTEL bro framework successfully. I'm having a hard time to
understand why inside my intel.log file, the information "Intel::ADDR" is
showing twice. In identified by the fields "seen.indicator_type" and
"matched sources".
Which seems wrong, in my understanding matched sources should've been
identified by the text "Bad Reputation Domain", which is actually end up
being identified as the field "fuid".
A log sample is below:

/usr/local/bro/logs/2017-01-23/intel.13\:00\:00-14\:00\:00.log.gz
