Deprecated RPZ Feeds

Deprecated RPZ Feed Name

Description

Base Hostnames

base.rpz.infoblox.local

Enables protection against known hostnames that are dangerous as destinations, such as APT, Bot, Compromised Host/Domains, Exploit Kits, Malicious Name Servers, and Sinkholes.

AntiMalware

antimalware.rpz.infoblox.local

Enables protection against known malicious hostname threats that can take action on or control of your system, such as Malware Command & Control, Malware Download, and active Phishing sites.

Ransomware

ransomware.rpz.infoblox.local

Enables protection against ransomware taking over your system. Ransomware will encrypt files on your system and require you to pay in order to get them decrypted. This feed prevents ransomware to contact the servers which it needs to encrypt your files.

Malware DGA Hostnames

malware-dga.rpz.infoblox.local

Domain generation algorithm (DGA) are algorithms seen in various families of malware that are used to periodically generate a large number of domain names that can be used as rendezvous points with their command and control servers. Examples include Ramnit, Conficker, and Banjori.

Antimalware IP

antimalware-ip.rpz.infoblox.local

Enables protection against known malicious or compromised IP addresses. These are known to host threats that can take action on or control of your system, such as Malware Command & Control, Malware Download, and active Phishing sites.

Suspicious

suspicious-med.rpz.infoblox.local

l

The Suspicious Domains feed enables protection against hostnames that have not been directly linked to malicious behavior but behave in a manner that suggests malicious behavior may be imminent.

Suspicious Lookalike

suspicious-lookalikes.rpz.infoblox.local

The Suspicious Lookalikes feed includes domains that appear to impersonate other trusted domains, but have demonstrated enough abnormal behavior to warrant concern.

Suspicious NOED

suspicious-noed.rpz.infoblox.local

The Suspicious Emergent Domains feed include high risk, new domains. These domains have only recently become active, and share one or more characteristics with other known malicious domains to warrant concern.

Newly Observed Emergent Domains

noed.rpz.infoblox.local

The NOED feed includes recently created and newly active domain names. These are not necessarily suspicious but some organizations may wish to log traffic going to these domains as there is a low likelihood that these domains would be visited normally.
