Central Concrete Supply Co., Inc.

On February 23, 2016, Central Concrete Supply Co., Inc. experienced a data breach resulting from a social engineering attack, specifically a phishing scheme targeting employee tax information. The incident led to the unauthorized access and theft of 2015 W-2 income and tax withholding statements for approximately 201 employees. The compromised data included highly sensitive personal and financial details such as names, addresses, phone numbers, tax identification numbers, Social Security numbers (SSNs), and income information. The breach was reported to the California Office of the Attorney General on March 1, 2016. The exposure of SSNs and financial records poses significant risks, including identity theft, tax fraud, and financial exploitation for the affected individuals. The attack exploited human vulnerability rather than technical flaws, highlighting the persistent threat of social engineering tactics in corporate environments. The company’s failure to prevent the theft of such critical employee data underscores the need for robust cybersecurity awareness training and multi-factor authentication for sensitive systems.
