The California Office of the Attorney General disclosed a data breach involving Computer Sciences Corporation (CSC) on April 3, 2013. The incident stemmed from the loss of a thumb drive containing sensitive personal information, specifically names and Social Security Numbers (SSNs) of individuals. While the exact number of affected individuals remains unknown, the exposure of such data poses significant risks, including identity theft, financial fraud, and reputational harm to those impacted. The breach highlights vulnerabilities in physical data security controls, as the unencrypted or improperly secured storage device was misplaced or stolen. Given the nature of the compromised data—SSNs being a prime target for cybercriminals—the incident underscores the critical need for robust data encryption, access controls, and employee training to prevent similar occurrences. The breach did not involve a targeted cyber attack but rather a human error or negligence, leading to potential long-term consequences for affected individuals.
