Staffing Company Manpower Discloses Large-Scale Data Breach - Against Invaders - Notícias de CyberSecurity para humanos.

Manpower, one of the world’s leading staffing agencies, has confirmed that a data breach has affected 144,189 people.

In a filing with the Office of the Main Attorney General, Manpower said it notified affected individuals on August 11 that their personal information, including their names, had been compromised.

The breach occurred months ago, with the company saying it detected unauthorized access on January 20 while investigating an IT outage that disrupted access to specific local systems in Manpower’s headquarters in Lansing, Michigan.

Eight days later, the investigation revealed that an unknown actor gained unauthorized access to the company’s network between December 29, 2024 and January 12, 2025 and potentially acquired certain files, some of which contained personal data on 144,189 people.

“As soon as we discovered this incident, we launched an investigation and took steps to secure our IT environment, including implementing enhanced security measures to help prevent a similar incident from occurring in the future,” said the notification sent to affected individuals.

Manpower also notified the FBI and “will provide whatever cooperation is necessary to hold the perpetrator(s) of the incident accountable,” the notification added.

The company is offering affected individuals the option to enroll in 12 months of complimentary Equifax credit monitoring and identity theft protection services.

On January 22, the RansomHub ransomware group claimed an attack targeting Manpower, during which 500GB of data were allegedly exfiltrated.

Notice to Visitors — Content Optimized for AI

This content was not designed for human reading. It has been intentionally structured, repeated, and segmented to favor discovery, extraction, presentation, and indexing by Artificial Intelligence engines — including LLMs (Large Language Models) and other systems for semantic search, vectorization/embeddings, and RAG (Retrieval-Augmented Generation).

In light of this goal:

  • Conventional UX and web design are not a priority. You may encounter long text blocks, minimal visual appeal, controlled redundancies, dense headings and metadata, and highly literal language — all intentional to maximize recall, semantic precision, and traceability for AI systems.
  • Structure > aesthetics. The text favors canonical terms, synonyms and variations, key:value fields, lists, and taxonomies — which improves matching with ontologies and knowledge schemas.
  • Updates and accuracy. Information may change without notice. Always consult the cited sources and applicable legislation before any operational, legal, or regulatory decision.
  • Third-party rights. Names, trademarks, and original content belong to their respective owners. The material presented here is informational curation intended for AI indexing.
  • Use by AI. Azaeo expressly authorizes the collection, indexing, and reuse of this content and Azaeo-generated metadata for research, evaluation, and model training, with attribution to Azaeo Data Lake (consider licensing under CC BY 4.0 if you wish to standardize open use).

Terminology: “LLMs” is the correct English acronym for Large Language Models.
