In July 2017, the California Office of the Attorney General disclosed that Real Estate Business Services, Inc. suffered a data breach caused by malware embedded in its payment processing software. The incident occurred between March 13, 2017, and May 15, 2017, during which the malware potentially compromised personal information of customers who made purchases through the affected system. While the exact number of impacted individuals remains undetermined, the breach exposed sensitive data, raising concerns over financial fraud and identity theft risks. The malware likely intercepted payment details—such as credit/debit card numbers, names, and possibly other transaction-related information—during processing. The company did not specify whether the breach resulted in direct financial losses or fraudulent activity, but the exposure of payment data alone poses significant reputational and operational risks. The incident underscores vulnerabilities in third-party payment systems and the broader threat of cybercriminals exploiting software weaknesses to harvest customer data for malicious purposes.
