An undisclosed number of individuals may be affected; anyone connected to the firm should check for any contact from the organisation and review their own accounts for unusual activity.

The number of people whose information may be involved remains unknown, and no official statement from the firm has clarified whether client records were among the files referenced.
Inside rhysida
Rhysida is a ransomware group that has conducted multiple operations against organizations in various sectors. Its typical approach involves gaining access to networks, exfiltrating data, and deploying ransomware to encrypt systems. The group maintains a leak site where it lists victims and, in some cases, publishes samples of claimed stolen material. Any assertion that Smoll & Banning appears on that site is treated as an unverified claim by the group until independently confirmed.
Who is Smoll & Banning, CPAs?
Smoll & Banning, CPA's, LLC operates as an independent accounting firm in Dodge City, Kansas. Firms of this type routinely handle financial statements, tax filings, payroll records, and other sensitive documentation for individuals and businesses. A breach affecting such an organization carries implications for client confidentiality because accounting practices centralize detailed financial and personal information in the course of their work.
What data was at risk
The listing refers only to “internal files exfiltrated in ransomware attack.” No specific categories of data have been confirmed. Accounting firms commonly store client tax returns, bank details, Social Security numbers, and business financial records, yet the exact contents of the files referenced in this case have not been disclosed. Without additional information from the firm or verified samples, the precise nature of exposed records cannot be determined.
The real-world impact
Clients of an accounting firm may face risks of identity theft or financial fraud if personal or tax-related information was among the exfiltrated files. The organization itself could encounter regulatory scrutiny and costs associated with investigation and notification. Because the number of affected individuals and the specific data types remain undisclosed, the full extent of potential harm cannot yet be assessed.
