As Log4Shell wreaks havoc, payroll service reports ransomware attack

beset by Log4Shell, arguably the most severe vulnerability ever, one of the biggest human resources solutions providers is reporting a ransomware attack that has taken its systems offline, possibly for the next several weeks. So far, the company isn’t saying if that critical vulnerability was the means hackers used to breach the systems.

The company said on Sunday that services using the Kronos Private Cloud had been unavailable for the past day, with the attack taking down Kronos’ UKG Workforce Central, UKG TeleStaff, and Banking Scheduling Solutions services.

“At this time, we still do not have an estimated restoration time, and it is likely that the issue may require at least several days to resolve,” Kronos representative Leo Daley wrote. “We continue to recommend that our impacted customers evaluate alternative plans to process time and attendance data for payroll processing, to manage schedules, and to manage other related operations important to their organization.”
