Ardent Health Services hit by ransomware

Several hospitals affiliated with Ardent Health Services have been targeted by ransomware attacks, leading to the rescheduling of appointments and redirection of patients to alternative medical facilities. The affected institutions include Hillcrest Healthcare Systems, Lovelace Health System, and UT Health.

Hackensack Meridian Mountainside Medical Center and Pascack Valley Medical Center have also experienced network outages due to malicious malware attacks.

The cyber-attacks occurred in late November 2023, with initial estimates suggesting that the infiltration may have taken place a few days prior.

Healthcare networks in Canada have also been impacted by cybercriminals, leading to disruptions and emergency diversions.

Europol, in collaboration with law enforcement agencies from various countries, conducted a sting operation resulting in the arrest of six individuals responsible for victimizing over 1800 people globally.

Ukraine Cyber Police, working with Europol, targeted two criminals using LockerGaga and Mega Cortex Ransomware tools. However, as one cybercriminal organization is dismantled, others quickly emerge, highlighting the ongoing challenge of combating cyber-crimes.
