U.S. Internet Disrupted As Firm Gets Hit By Cyberattack
(CBS) — Twitter experienced renewed outages Friday afternoon following hours ofthat took down numerous sites earlier in the morning across the U.S. East Coast.
A wave of reports of problems accessing many popular websites came after the servers at a major internet management firm were hit by a.
New Hampshire-based Dyn said its server infrastructure suffered a distributed denial-of-service (DDoS) attack, which occurs when a system is overwhelmed byelectronic traffic.
In a statement provided to CBS News, the U.S. Department of Homeland Security said it was aware of the attack and is “investigating all potential causes.”
The scale of the attack led to suspicions that it might be state sponsored, but ZDNet security editor Zack Whittaker said the evidence is not yet clear. “It may or may not have been sponsored by some state-sponsored actor, at this point it’s simply too early to tell,” he told CBS News.
DDoS attacks are nothing new, but Whittaker said they’ve been getting “worse and worse” recently, and this one “must be off the charts.”
Dyn issued a series of statements about the service disruption early Friday local time, tweeting that as of 9:20 a.m. ET, “services have been restored to normal.”
However, the company detected another wave of DNS attacks just before noon and acknowledged that the problem was not yet solved. “We are continuing to mitigate a DDoS against our Managed DNS network,” it said.
The level of disruption caused was hard to gauge, but Dyn provides internet traffic optimization to some of the biggest names on the web, including, , Airbnb, Spotify, and others, and users of many sites were reporting problems.
Jason Read, the founder of Gartner Inc.-owned internet performance monitoring firm CloudHarmony, said his company tracked a half-hour-long disruption early Friday in which roughly one in two end users would have found it impossible to access various websites from the East Coast.
Read said that Dyn provides services to some 6 percent of America’s Fortune 500 companies, meaning a big potential for disruption.
“Because they host some major properties it impacted quite a few users,” he said.
The site Downdetector.com, which tracks service outages, lit up with reports of problems accessing Twitter and other sites Friday morning.
