"As soon arsenic the Log4j vulnerability was precocious publically reported, we initiated accelerated patching processes … While we presently person nary denotation that determination is, we are investigating whether oregon not determination is immoderate narration betwixt the information incidental described supra and the Log4j vulnerability," UKG said. 

Causes aside, the extremity effect is that a batch of large companies (KPC is utilized by Tesla, the City of Cleveland government, and aggregate banks and fiscal institutions) can't process payroll, and that means radical mightiness spell into the holidays unpaid.

Kronos outage: What was affected

Kronos Private Cloud is UKG's hosting solution for its Workforce Central, TeleStaff, Healthcare Extensions and Banking Scheduling Solution software. The ransomware attack, which was detected connected December 11, has meant that KPC and its hosted solutions are unavailable to customers. 

Make nary mistake: This isn't a tiny problem. In a connection astir the outage, UKG said that it has nary estimated clip of resolution, that its backups aren't disposable until they "determine the champion approach" to restoration. UKG frankincense "continues to powerfully urge our customers enactment with their enactment to activate their concern continuity plans."

"Customers volition beryllium much apt to judge downtime from thing similar a terrible upwind lawsuit due to the fact that they tin much easy subordinate to a kinetic challenge.

The authoritative enactment from UKG is that its probe is ongoing, but the City of Cleveland told a section quality presumption that UKG told it that the onslaught "may person compromised immoderate employees' archetypal and past names, addresses, past 4 SSN digits and worker ID," Cleveland's WKYC reported.  

Ransomware gangs person been known to extort victims by threatening to (or actually) releasing delicate data, and there's nary crushed to presume this onslaught is immoderate different. If, arsenic is presently believed, Log4Shell isn't involved, past there's nary telling however agelong Kronos Private Cloud could person been compromised. 

"It's apt the attacker had been targeting Kronos for immoderate clip anterior to the detonation of the ransomware," Mellen said. Until we cognize erstwhile and however the archetypal penetration occurred, it's harmless to presume Kronos Private Cloud customers whitethorn person had delicate information stolen and react accordingly

How Kronos Private Cloud customers tin recover
