DDoS Attacks on Election Infrastructure Can Hinder Access to Voting Information, Would Not Prevent Voting.
The Federal Bureau of Investigation (FBI) and Cybersecurity and Infrastructure Security Agency (CISA) are issuing this announcement to raise awareness that Distributed Denial of Service (DDoS) attacks on election infrastructure can hinder access to voting information but would not prevent voting. DDoSs are common cyber attacks that can slow or render election-related public-facing websites inaccessible, which could hinder voters’ ability to access voting information or voting results. A DDoS attack occurs when attackers flood a public-facing, Internet accessible server with requests, rendering the targeted server slow or inaccessible. This prevents users from accessing online resources, such as web pages and online accounts, and may disrupt business activities for a period of time.
