From 4fd3323220fc503bb57dcd64a3266faf7b6c412e Mon Sep 17 00:00:00 2001 From: rderkach Date: Mon, 25 Oct 2021 18:01:05 +0300 Subject: [PATCH] Update Recorded future expansion module with the new data In this release, we added new data that we have called Links. It represents better and more filtered related data. Also did some code formatting. --- .../modules/expansion/recordedfuture.py | 495 +++++++++++------- 1 file changed, 316 insertions(+), 179 deletions(-) diff --git a/misp_modules/modules/expansion/recordedfuture.py b/misp_modules/modules/expansion/recordedfuture.py index ccea31b..9894968 100644 --- a/misp_modules/modules/expansion/recordedfuture.py +++ b/misp_modules/modules/expansion/recordedfuture.py @@ -1,8 +1,14 @@ import json import logging import requests -from requests.exceptions import HTTPError, ProxyError,\ -
