Major Websites Across U.S. Disrupted
Many websites were inaccessible to people across the United States on Friday after a company that manages crucial parts of the internet’s infrastructure said it was under attack.
The attack appears to have relied on hundreds of thousands of internet-connected devices like cameras, baby monitors and home routers that have been infected — without their owners’ knowledge — with software that allows hackers to command them to flood a target with overwhelming traffic.
A distributed denial-of-service attack, or DDoS, occurs when hackers flood the servers that run a target’s site with internet traffic until it stumbles or collapses under the load. Such attacks are common, but there is evidence that they are becoming more powerful, more sophisticated and increasingly aimed at core internet infrastructure providers.
