Business Systems House, a partner of ADP, experienced a breach in September 2024, leading to sensitive Broadcom files appearing on the dark web.
Customers of Broadcom had their data exposed after a supply chain attack, with data such as National ID numbers, salary details, and personal contact information being leaked.
The stolen data was discovered on the internet in December 2024, prompting Broadcom to advise users to enable multi-factor authentication and monitor financial records.
The attackers, known as El Dorado and later rebranded as BlackLock, are a ransomware group consisting of Russian-speaking individuals. The incident highlights the importance of cybersecurity measures for both businesses and individuals.
