WCAS Management, L.P. (“WCAS”) has recently informed individuals of a data security incident that may have exposed their personal information. While there is no evidence that the data has been misused, WCAS is offering identity protection services to help mitigate potential risks.

WCAS Data Breach Investigation

On August 1, 2025, WCAS detected unauthorized activity within its internal network, which was later determined to be a ransomware attack. The threat actor was in the system for less than 24 hours, accessing the network from July 31, 2025, through August 1, 2025. Upon discovering the incident, WCAS acted swiftly by isolating the affected systems, activating its incident response protocol, and notifying federal law enforcement.

To assess the extent of the breach, WCAS engaged both internal and external cybersecurity experts, including forensics specialists, who conducted a comprehensive review of the network. They worked to eradicate the threat actor and took additional steps to enhance the company’s systems to prevent similar incidents in the future.

The breach involved the exfiltration of a limited number of files, some of which contained sensitive personal information. While there has been no indication that any of the data has been misused, WCAS is taking protective measures to safeguard affected individuals’ information and mitigate any potential risks.

When Did This Breach Occur?

• Breach Detected: August 1, 2025
• Unauthorized Access Period: July 31, 2025 – August 1, 2025

The data potentially compromised in the attack included:

• Full Name
