Evernote says it's working to neutralize a DDoS attack

Evernote announced Tuesday that it was hit with a distributed denial of service attack that made it unavailable for many of its 100 million users.

The popular online note-taking service first posted to Twitter Tuesday evening that it was experiencing issues and was trying to resolve the matter. About an hour later, the company revealed it was the victim of a DDoS attack.

"We're actively working to neutralize a denial of service attack," Evernote tweeted. "You may experience problems accessing your Evernote while we resolve this."

Typically DDoS attacks don't cause breaches of user data, instead they're meant to disrupt a service by overwhelming a company's servers with massive amounts of traffic.

Evernote spokeswoman Ronda Scott told CNET the DDoS attack began around 2:25 p.m. PT and the company had it under control by 6:15 p.m. PT.

"We expect that there may be a hiccup here and there in the coming hours, but Evernote is now accessible," Scott said. "We do not know its specific origins and this is the first time Evernote has been impacted by a DDoS attack. I can confidently report as is the usual case with these types of attacks, no accounts were compromised and no data was lost."

This isn't the first time Evernote has fallen prey to hackers. A year ago, attackers broke into the company's systems and were able to access some user data. However, no sensitive financial information was stolen and no user content was affected. Nevertheless, Evernote had users reset their passwords.
