Update arf.json

[eshanaswar]

We have started a new malware threat feed (REScure) which is accessible at :

homepage : https://rescure.fruxlabs.com/ Feedpath : https://rescure.fruxlabs.com/rescure_blacklist.txt Feedpath : https://rescure.fruxlabs.com/rescure_domain_blacklist.txt

The feed is curated form an inhouse threat intelligence solution and is updated at every 6 hours. A blogpost detailing about this is mentioned here :

Currently limited to only malicious IPs and domains, we will enhance this by adding IoCs such as malware hashes, et al in future.

Thanks !
