Hailstorm attacks can be over in a matter of minutes so Spamhaus has improved the update frequency from 60 seconds to continuously updated for subscribers of its Data Query Service (DQS).
Spamhaus researchers gather threat intelligence from across the internet and the first indication of a hailstorm attack automatically feeds into the standard Spamhaus email block lists. This means DQS subscribers can now block hailstorm traffic at the start of the attack, thwarting the bulk of spam sent by cyber criminals.
In a recent live hailstorm attack, Spamhaus researchers were able to identify the threat and update the Content Blocklists including Zero Reputation Domain, Zen and Domain Blocklist, blocking 85% of the volume of the attack which was over in just three minutes.
Spamhaus subscribers who currently use rsync rather than DQS, please contact us for more information about how to access this service.
