WeiserMazars, LLC

On October 10, 2012, Accume Partners suffered a data breach due to a stolen laptop belonging to WeiserMazars, LLC, an affiliated third-party service provider. The incident was reported by the California Office of the Attorney General on December 10, 2012. The breach exposed sensitive personal information of plan participants, specifically **names and Social Security numbers (SSNs)**. The compromised data belonged to individuals associated with Accume Partners’ retirement or benefit plans, raising concerns over potential identity theft, financial fraud, or misuse of the exposed SSNs. While the exact number of affected individuals was not specified in the report, the exposure of such highly sensitive information posed a significant risk to the privacy and financial security of the impacted participants. The breach stemmed from the physical theft of an unencrypted or inadequately secured device, highlighting vulnerabilities in data protection protocols involving third-party vendors.
