Cyberattack on Manpower’s Michigan Office Compromises Data for 144,000 PeopleWorkday Data Breach in Widespread Social Engineering Scam

614After Incident
CRITICAL-149
MAN847081825
A cyberattack on Manpower’s franchise office in Lansing, Michigan, resulted in unauthorized network access between late December 2024 and mid-January 2025. The breach, attributed to the ransomware group RansomHub, compromised the personal data of 144,189 individuals, including employees and potentially customers. The incident was discovered after an IT outage on January 20, 2025. While isolated to the franchise’s independent data platform, the attack exposed sensitive information, prompting Manpower to offer one year of free credit monitoring and identity theft protection to affected individuals. The company reported the incident to the FBI and is cooperating with investigations. The breach underscores vulnerabilities in franchise-level cybersecurity and the escalating threat of ransomware-driven data exfiltration.
