Description

ARC Document Solutions, Inc. detected suspicious activity within its computer network on January 15, 2023, prompting immediate containment measures to secure its systems. The company engaged a third-party forensic firm to investigate the incident, which confirmed unauthorized access to its network between January 12 and January 18, 2023. Forensic analysis revealed that the threat actor had accessed files containing confidential consumer information, though the organization did not publicly specify the exact data types compromised. ARC initiated a comprehensive review of affected files to identify impacted individuals and determine the scope of exposed information. This process concluded in May 2023, leading to data breach notification letters being sent to affected consumers starting May 10, 2023. The company filed formal notice of the breach with the Montana Attorney General on the same date, fulfilling regulatory obligations. No technical details regarding attack vectors, malware variants, or infrastructure vulnerabilities were disclosed in available reporting.

The breach exposed sensitive consumer information handled by ARC Document Solutions, a San Ramon-based business services provider specializing in printing and scanning services for over 90,000 clients nationwide. The company serves architectural, engineering, construction, education, healthcare, and corporate sectors through its network of 140+ North American print centers. With 1,764 employees and approximately $286 million in annual revenue, the incident potentially affected customers across multiple industries that rely on ARC's document management services. While the organization confirmed unauthorized access to confidential data, it did not quantify the number of impacted individuals or specify whether employee information was compromised. The breach notification process focused on consumer data exposure risks, with identity theft and fraud highlighted as potential consequences in generic advisories accompanying disclosure letters. No operational disruptions or ransomware demands were mentioned in connection with the incident.
