The ChristianaCare website remained down early Tuesday night.
Visitors were greeted tonight with a message indicating that the site was checking out the security of the browser of the person logging in.
The site was restored later in the evening.
ChristianaCare added more details indicating that it was part of worldwide attack on healthcare organizations.
The outage was described as a distributed denial-of-service (DDoS) attack on the main public website, christianacare.org,
A DDoS attack is a malicious attempt to disrupt the normal traffic of a website by overwhelming it with a flood of internet traffic.
“Our information technology team worked quickly to resolve the situation, and normal website service was restored within several hours,” ChritianaCare reported.
The attack only affected the ability for people to access ChristianaCare’s public website. There was no disruption to any other IT systems, with no impact on data security.
DelawareOnline reported a pro-Russian hacking group claimed credit for knocking out hospital websites around the nation. Hospital websites have been targeted by hackers, with authorities warning of such activities.
Reports of sites being taken down were reported as early as Monday in the U.S. and the UK.
