CYBERSECURITY

Staffing giant Manpower has confirmed it suffered a cyberattack in late 2024 in which it lost sensitive data on almost 145,000 people.

Manpower of Lansing, MI, helps match individuals with companies needing workers, offering options like short-term jobs, trial-to-permanent roles, and full-time placements. It operates as part of the worldwide ManpowerGroup network.

What Happened?

On or about January 20, 2025, Manpower of Lansing faced an IT outage, causing access issues to some local systems. They promptly took measures to secure their network and began investigating the cause. It was found that an unidentified party accessed their network sometime between December 29, 2024, and January 12, 2025, potentially obtaining certain files. Some of these files may have included personal information, such as names linked with other identifiers.

The RansomHub group claimed responsibility and reported stealing 500 GB of data. Manpower indicated potential exposure of sensitive information for about 144,189 individuals and began notifications around August 12, 2025.

What’s Next?
