Bulk Sensitive Data Rule

The Department of Justice's Bulk Sensitive Data Rule in 2025 addressed broad data privacy violations, and created new legal rights and remedies for individuals whose personal data has been mishandled without proper consent or protection.

How Your Information Becomes a National Security Threat

Data brokers and mobile applications collect vast quantities of personal information and resell it to the highest bidders, so almost any buyer, even foreign governments, can acquire detailed intelligence on citizens.

The scope of exploitable information includes location data and browsing histories as well as genetic information. Foreign intelligence services cross-reference these data points and build psychological profiles for blackmail purposes. That's how bulk data aggregation transforms privacy violations into national security threats.

Commercial incentives drive this exploitation. Mobile software development kits can transmit user data to foreign servers and other nations may access bulk data through legitimate-appearing business transactions rather than hacking or espionage operations.

What Is the Bulk Sensitive Data Rule?

The DOJ's Data Security Program took effect April 8, 2025, following Executive Order 14117. This regulation prohibits or restricts transfers of American personal information to six "countries of concern": China (including Hong Kong and Macau), Russia, Iran, North Korea, Cuba, and Venezuela.

Six data categories receive protection. Covered personal identifiers, precise geolocation data, biometric identifiers, genetic information, personal health data, and personal financial data.

Prohibited Transactions and Compliance Requirements

This bulk data rule distinguishes between prohibited and restricted transactions. Restricted transactions include vendor agreements, employment arrangements, and investments granting foreign entities data access. These require comprehensive security programs meeting Cybersecurity and Infrastructure Security Agency standards.

Real-time bidding systems face particular scrutiny. The rule characterizes such systems as data brokerage, effectively prohibiting current implementations including participants from countries of concern.

Mobile applications with tracking software transmitting data to foreign servers must eliminate these components or implement stringent controls. Software development kits from Chinese or Russian companies create ongoing transfer relationships violating prohibition standards.

Legal Penalties for Data Misuse: DOJ Enforcement and Criminal Prosecution

Civil violations trigger fines up to $368,136 per transaction, or double the transaction value if greater. For organizations conducting thousands of daily transfers, cumulative penalties could prove catastrophic.

Current enforcement operates at full intensity, with additional compliance deadlines for due diligence and audits effective October 6, 2025.

Emerging Litigation Against Tech Companies

Recent lawsuits combine traditional privacy claims with Bulk Sensitive Data Rule violations.

• Baker v. Index Exchange alleges real-time bidding constitutes unlawful wiretapping under the Electronic Communications Privacy Act. The complaint characterizes deliberate interception and transmission of communications to Chinese platforms as both privacy violations and rule breaches.
• Porcuna v. Xandr alleges Microsoft's advertising subsidiary enabled Temu to conduct covert data collection through cookie synchronization, allowing foreign entities to match user identifiers across platforms.
