ExtendIntel

This package extends the Intel package to log more fields

Intel log

Without this package, the standard intel.log would have content like the following:

{
  "@path":"intel",
  "@sensor":"Lab-AP200",
  "@timestamp":"2023-01-06T05:13:38.841292Z",
  "ts":"2023-01-06T05:13:38.841292Z",
  "uid":"CNh51N3dSRfMZG1Pt4",
  "id.orig_h":"195.133.40.86",
  "id.orig_p":64910,
  "id.resp_h":"192.168.13.20",
  "id.resp_p":80,
  "seen.indicator":"77.247.181.165",
  "seen.indicator_type":"Intel::ADDR",
  "seen.where":"Conn::IN_ORIG",
  "matched": [
    "Intel::ADDR"
  ],
  "sources": [
    "blocklist_de",
    "cinsscore_ci_badguys",
    "blocklist_net_ua",
    "Mandiant",
    "dshield_block"
  ],
}

If the ExtendIntel Zeek package is loaded, the intel.log will be enriched with additional content like the following:

  "threat_score": [100],
  "verdict": ["malicious"],
  "verdict_source": ["analystVerdict"],
