Impact on Maximus

As a contractor managing and administering various government-sponsored programs, the data breach has dealt a significant blow to Maximus.

Due to the breach, the company plans to record an expense of approximately $15 million for investigating and remediating the incident.

The investigation into the data breach is still ongoing, and Maximus is working to determine the full extent of the compromise.

The company has started notifying affected customers, as well as federal and state regulators, about the breach.

However, the process of notifying all impacted individuals is expected to take several more weeks.

Well-Known Perpetrators And Wider Impact

The group responsible for this large-scale data breach is the Clop ransomware gang.

Clop has listed numerous organizations on its dark web leak site, indicating the scale of the attacks. Accountancy giants, Deloitte, PwC, and Ernst & Young are among the victims.

Speaking of the worldwide impact, the MOVEit Transfer hacks have affected more than 500 organizations, exposing the personal information of over 34.5 million people.
