Data Breach Alert: Investigation Launched into Manpower of Lansing, MI, Affecting 144,189 Clients

Data Breach Investigation on Manpower of Lansing, MI

Manpower of Lansing, MI, a staffing company based in Michigan, is under scrutiny following a data breach that has potentially compromised the personal information of around 144,189 clients. The investigation is being conducted by Schubert Jonckheer & Kolbe LLP, a law firm specialized in corporate class actions. This alarming incident has raised significant concerns regarding data security, especially in a world where identity theft and personal data misuse are increasingly common.

On January 20, 2025, the company experienced a major outage of its IT systems, which led to revelations that an unauthorized entity had infiltrated its network from December 29, 2024, to January 12, 2025. The breach is believed to involve sensitive personal data, including various forms of identification, social security numbers, addresses, contact details, corporate communications, and HR data analytics – all collected over numerous years.

The cybercriminal group linked to this incident is thought to be RansomHub, which claims to possess a staggering 500 gigabytes of Manpower’s client data. This extensive collection not only includes personal information vital for identity verification but also confidential business documents such as financial statements and contracts. The scope of the breach raises serious questions about how effectively organizations manage their cybersecurity measures, especially those handling sensitive consumer data.

Despite the breach occurring in late 2024, affected clients were not informed until around August 12, 2025, which potentially violates both state and federal notification laws. This delay could further complicate the matter, as clients' vulnerability to identity theft now escalates, leaving many individuals anxious about the misuse of their personal information.

Individuals who believe their data might have been compromised are urged to take proactive measures to safeguard their identities. This includes monitoring financial statements for unusual activity, utilizing credit monitoring services, and being on the lookout for any notifications related to identity theft. Moreover, those associated with Manpower are encouraged to reach out for legal support to understand their rights and options in light of this incident.

Schubert Jonckheer & Kolbe LLP, based in San Francisco, specializes in representing shareholders and consumers in cases against corporate entities. In light of the significant impact of this breach, the firm is dedicated to ensuring those affected can secure justice and accountability from Manpower. If you received a notification regarding the data breach or are related to Manpower in any capacity, it’s crucial to seek more information about the legal avenues available to address the potential breaches of privacy and identity theft risks.

In the age of digital interactions, the importance of robust cybersecurity protocols cannot be overstated. Organizations must prioritize safeguarding sensitive information to maintain consumer trust and protect against malicious actors seeking to exploit vulnerabilities. Moving forward, the focus will be on not only rectifying the consequences of this breach but also implementing more stringent safeguards to prevent similar incidents in the future. The legal ramifications stemming from this breach and the broader implications for data handling practices across organizations must be addressed effectively to ensure a safer digital environment for all consumers.
