Popular note-taking app Evernote was hit by a distributed denial of service (DDoS) attack on Tuesday evening that left millions of users without access to the service.
Evernote admitted something was amiss at around 11pm UK time when it posted on Twitter that the service was unavailable.
Evernote service is currently unavailable. We are working to resolve the issue. Updates to follow. Thanks for your patience.— evernote (@evernote) June 10, 2014
Around an hour later it provided a more detailed explanation, revealing that it was being hit by a DDoS attack.
We're actively working to neutralize a denial of service attack. You may experience problems accessing your Evernote while we resolve this.— evernote (@evernote) June 10, 2014
Eventually the firm managed to quell the attack and services returned, although it advised customers that disruptions could linger.
Evernote is up and running. There may be a hiccup or two for the next 24 hours. We appreciate your patience.— evernote (@evernote) June 11, 2014
The incident underlines the threats facing firms from all kinds of web attacks and incidents, be it data breaches, phishing scams or DDoS attacks.
This is not the first time Evernote has been hit by web crooks. Hackers infiltrated systems in March 2013, although the firm said that no financial information was affected.
DDoS attacks are used regularly against major firms and organisations to cause mayhem and disrupt services. Banking giant RBS was hit in December, at a key time when customers were trying to do online shopping ahead of Christmas.
