FBI reportedly warned this week that attackers repeatedly attempted to disrupt a state’s voter registration website with a distributed denial-of-service attack. The FBI issued a Private Industry Notification that described the attempted DDoS attack, Bleeping Computer says it obtained a copy of the alert. FBI declined to comment on specifics but told ISMG: “In furtherance of public-private partnerships, the FBI routinely advises private industry of various cyber threat indicators” DDoS attacks seen in recent years can cause sudden bursts of traffic – sometimes as much as 15 percent of all DNS query traffic – in order to overwhelm the server and shut down a site.”]
