Case Study: Global Holding Company defeats major ransomware attack and restores operations with CyberArk Privilege Cloud

CyberArk Responds Within Hours to Navigate Global Business Out Of Major Ransomware Attack

A global holding company (>$2B revenue, 5,000+ employees across multiple sectors) was struck mid‑summer by a major ransomware attack that leveraged a highly privileged credential to gain domain admin rights, putting critical applications, data and the company’s reputation at risk. The incumbent privileged access management (PAM) provider could not respond quickly enough, leaving leadership scrambling for an urgent remediation partner.

The company engaged CyberArk, which rapidly deployed a Remediation Team, Jump Start and Privilege Cloud (with Endpoint Privilege Manager), rebuilt domain controllers from backups, onboarded ~300 key users, and put privileged credentials into automated rotation. The attack was defeated, the ransom demand halted, exploited vulnerabilities were eradicated, and a standardized, automated PAM program now provides faster anomaly detection and validated protection (confirmed by a successful simulated internal attack).
