Description
On June 16, 2026, ransomware was deployed across portions of River Financial Corporation’s server environment. The attack was identified three days later, on June 19, prompting the company to take the affected systems offline and disable administrative accounts that had been compromised. River engaged a third‑party forensic firm to assist in investigating the nature and scope of the incident, including whether any personally identifiable information was subject to unauthorized access or exfiltration. On June 25, River filed a report with the U.S. Securities and Exchange Commission stating that it was conducting this investigation.
Subsequent 8‑K filings with the SEC revealed that hackers had accessed parts of River’s network and exfiltrated certain data, and that at least four lawsuits have been filed against the company. A July 30 filing indicated that River had not yet determined whether the attackers had stolen any personal information from its systems. The filing also showed that River had engaged with the threat actor to obtain representations that the stolen data had been deleted. River has not disclosed details about the threat actor responsible, and the method by which the attackers initially compromised the network remains unclear.
As part of its response, River took steps to attempt to suppress the affected data, including obtaining representations from the threat actor that the data in its possession had been deleted. The company has not yet confirmed whether the incident is reasonably likely to materially impact its business or financial condition. Ongoing investigations continue to assess the full scope and impact of the ransomware attack.
