The ransomware attack on Business Systems House (BSH), a payroll provider for Broadcom, resulted in significant employee data theft. Although the attack occurred in September 2024 and the data was leaked online in December, Broadcom was not informed until May 2025. The attack, claimed by the El Dorado group, exposed vulnerabilities in the security of extended vendor ecosystems, particularly during Broadcom's transition away from its payroll providers, ADP and BSH. This incident underscores ongoing cybersecurity risks for organizations that rely on third-party services.
