Citi reported a data security breach involving personally identifiable information (PII) exposed in publicly accessible bankruptcy court filings. The incident resulted from limitations in electronic redaction methodologies or imperfect manual processes, allowing personal information to be read by individuals accessing court records. Citi states it is not aware of any actual misuse or identity theft. Remediation included blocking access to the original filings, substituting them with new filings containing permanently concealed information, and offering one year of complimentary credit monitoring to affected consumers.
