Several
cybersecurity incidents have demonstrated that sealed court documents are not always secure in practice, with
vulnerabilities and
data breaches exposing sensitive information. In January 2021, following the
SolarWinds cyber attack, the
U.S. Bankruptcy Court United States District Court for the District of Nevada announced that its Case Management/Electronic Case Files
CM/ECF system had been potentially compromised. The judiciary stated that additional safeguards were being implemented to protect filings, and that the review of the incident and its impact was ongoing. Reports noted that the breach raised concerns about exposure of highly sensitive and sealed documents submitted through the
CM/ECF system. In 2023,
security researcher Jason Parker, following a tip from an activist, identified flaws in online court systems that exposed sealed records including confidential testimony and medical records through publicly accessible portals. In 2024, a
cyber intrusion targeting attorneys in a civil case involving Representative
Matt Gaetz led to the unauthorized access and leak of sealed depositions and related records. The breach exposed confidential testimony and financial records, some of which were later reported by news outlets, raising concerns about the security of electronically stored legal materials and the handling of sealed filings. In 2025, multiple reports confirmed that the federal judiciary's
CM/ECF and
PACER (law) filing system was compromised, exposing sealed indictments, confidential
informant information, and other sensitive filings. Some courts temporarily reverted to paper-based filing to mitigate the risks of further disclosure. The FBI later confirmed that the breach had exposed sealed records, and investigators suspected foreign state actors were involved. == GAO publications referencing sealed records ==
