Insight Partners Confirms Ransomware Attack, Exposing Data of 12,000 Individuals
Venture capital firm Insight Partners has disclosed a ransomware attack that compromised the personal data of over 12,000 individuals, including employees, former staff, and limited partners. The breach, first acknowledged in a filing with Maine’s Attorney General this week, revealed that attackers accessed HR and finance servers on or around October 25, 2024, exfiltrating data before deploying encryption on January 16, 2025.
The stolen data included sensitive information about Insight’s funds, management companies, portfolio firms, banking records, and tax documents. Personal details of current and former employees, as well as high-net-worth limited partners, were also exposed. Insight, which manages over $90 billion in assets and backs companies like Twitter, Wiz, and SentinelOne, has notified affected individuals and offered credit monitoring services.
The firm stated it has since rebuilt affected systems, patched vulnerabilities, and strengthened security measures to prevent future incidents. However, the identity of the attackers, ransom demands, and whether any payment was made remain undisclosed. Insight Partners has not responded to further inquiries.
