Online reader site Feedly says it is under a denial of service attack, with the attacker demanding money to bring an end to service interruption.
In a brief post on the company blog, the developers let all customers know of the problem, and promises to update users as the situation develops.
"Criminals are attacking Feedly with a distributed denial of service attack (DDoS)," the company said on its blog. "The attacker is trying to extort us money to make it stop. We refused to give in and are working with our network providers to mitigate the attack as best as we can."
It seems that the cyber criminals have struck before and Feedly is working with other victims and with law enforcement in a bid to track the crooks down.
Feedly has updated its bog and said that normal service will be restored in a "few more hours".
"We're making some changes to our infrastructure that will allow us to bring feedly back online. However, these things take some time to put into place and it may still be a few more hours before service is restored. Thank you so much for your patience and for sticking with us. Remember, none of your data was compromised or lost in this attack," the site said.
