Flint, Michigan-based Hurley Medical Center was targeted with a cyber attack this past week, soon after the hacktivist group Anonymous released a video promising "justice" for the city's ongoing water crisis.

The attack was confirmed by the hospital Jan. 21.

"Hurley Medical Center has IT systems in place, which aid in detecting a virus or cyber attack," spokeswoman Ilene Cantor said, according to MLive. "As such, all policies and protocols were followed in relation to the most-recent cyber attack on our system. Patient care was not compromised and we are closely monitoring all systems to ensure IT security is consistently maintained."

Anonymous' posted a video online launching what it dubbed the #OpFlint campaign.

While the attack closely followed the release of the video, there's no confirmation that Anonymous is responsible for the Hurley Medical Center breach.

If so, however, it wouldn't be the first time the group has been connected to a hospital hack. In April 2014, Boston Children's Hospital was targeted with multiple DDoS and phishing attacks, reportedly orchestrated by Anonymous members angry about the controversial child custody case of Justina Pelletier, who was then being held at Boston Children's against the wishes of her parents.

Those attacks, "designed to bring down the site by overwhelming its capacity," according to a hospital spokesperson, lasted for days.
