JHT Holdings, Inc.

On May 7, 2021, the Washington State Office of the Attorney General disclosed a ransomware attack targeting JHT Holdings, Inc., discovered on March 22, 2021. The incident resulted in the compromise of personal data belonging to 511 Washington residents, including names and Social Security numbers (SSNs) highly sensitive information that elevates risks of identity theft, financial fraud, and long-term reputational harm. While the company implemented post-breach security measures, the exposure of SSNs signifies a severe violation of data protection standards. Affected individuals were notified via letters, though the delay between discovery (March) and public reporting (May) may have exacerbated vulnerabilities. The attack underscores the growing threat of ransomware-driven data exfiltration, particularly when targeting personally identifiable information (PII) at scale. No evidence suggests broader systemic disruption, but the leak of customer PII aligns with high-severity cyber incidents requiring regulatory scrutiny and potential legal repercussions for the company.
