ARC Community Services’ Data Breach Investigation

ARC Community Services, a social services organization based in Madison, Wisconsin, experienced a ransomware attack that led to a significant data security breach. On November 4, 2024, ARC Community detected unauthorized activity within its network. Immediate action was taken to mitigate the situation, including taking its systems offline and engaging legal counsel and cybersecurity experts to investigate the incident.

The organization retained CFC Security, Inc. (doing business as CFC Response), a leading cyber forensics firm, to assist in the investigation. The forensic investigation confirmed that the incident was caused by a ransomware attack carried out by an unauthorized actor known as “INC.” It was determined that the attacker had accessed and acquired data from ARC Community’s network without authorization.

Following an extended review process, ARC Community confirmed on August 28, 2025, that personally identifiable information (PII) was present in the compromised files. This supplemental review concluded on November 6, 2025, and confirmed that the names and Social Security numbers of at least two New Hampshire residents were among the exposed data.

ARC Community continues to assess the breach and has stated that additional updates will be provided if further information becomes available. The organization has not waived any rights or defenses under state jurisdiction but is complying with New Hampshire’s data breach notification laws.
