Within the next few hours, updated NVD and Cb Reputation Threat feeds will be published to all Cb Response customers per this post:
This announcement does not affect Cb Protection or Cb Defense customers.
Action Reminder: Opt-in now required for both feeds
These feeds are now customer-specific, and require that Cb Response customers opt-in to sharing hashes with the Cb Collective Defense Cloud to receive content in either feed. If you do not opt-in to sharing hashes with the Collective Defense Cloud, these feeds will contain no reports. Opt-in settings are available in the Cb Response console via "Administration -> Sharing Settings"
