Cybersecurity researchers at Cisco Talos mentioned Vice Society is understood to be “fast to use new safety vulnerabilities to assist ransomware assaults” and continuously exploits Home windows PrintNightmare vulnerabilities throughout assaults.
“As with different menace actors working within the big-game searching area, Vice Society operates an information leak web site, which they use to publish information exfiltrated from victims who don’t select to pay their extortion calls for,” Cisco Talos defined final month.
Cybersecurity agency Darkish Owl added that Vice Society is “assessed to be a potential spin-off of the Howdy Kitty ransomware variant based mostly on similarities within the strategies used for Linux system encryption.” They have been implicated in a ransomware assault on the Swiss metropolis of Rolle in August, in keeping with Black Fog.
A number of hospitals — Eskenazi Well being, Waikato DHB and Centre Hospitalier D’Arles — have been featured on the prison group’s leak web site and the group made waves this week by posting the information of Barlow Respiratory Hospital in California.

The aged, kids and any others who require medical consideration possible will be unable to get it as shortly and effectively as they might want whereas the hackers maintain hospital methods and information prisoner,” Jelley mentioned.
“To not point out that healthcare amenities are already struggling to maintain up as COVID-19 instances surge as soon as once more in lots of locations throughout the nation. Stopping ransomware assaults is a noble effort, however as illustrated by the Memorial Well being System assault and so many others prefer it in latest months, preparation for coping with the aftermath of a profitable assault is extra essential than ever.”
