Court filings in a US leak investigation indicate the FBI was unable to forensically extract data from Washington Post reporter Hannah Natanson’s iPhone because Apple’s Lockdown Mode was enabled. The government document states the FBI’s Computer Analysis Response Team (CART) “could not extract that device,” offering a rare, real-world data point on Lockdown Mode’s effectiveness against at least some standard law-enforcement mobile forensics workflows.
The filings also describe limited recovery from the device’s SIM card via a CART tool that produced an auto-generated HTML report containing only the phone number, and note the FBI paused further extraction attempts due to a court “Standstill Order.” The search and seizure occurred amid an investigation into government contractor Aurelio Perez-Lugones, whom prosecutors believe was a source for classified information; investigators also reviewed Signal messages between Perez-Lugones and the reporter as part of the case. Apple positions Lockdown Mode (introduced in 2022 for iPhone/iPad/Mac) as a high-risk protection that reduces attack surface by restricting attachments, inbound FaceTime from unknown contacts, certain web technologies, and other features.

After the seizure, the FBI was unable to extract data from the journalist's locked iPhone because Apple's Lockdown Mode was enabled. Multiple reports described the case as an example of Lockdown Mode frustrating law-enforcement forensic access.
The FBI seized a Washington Post journalist's iPhone during an investigation. The reporting identifies this seizure as the incident in which investigators later tried to access data on the device.
Apple released Lockdown Mode as an optional iPhone security feature designed for people at high risk of targeted attacks, sharply restricting device functionality to reduce the attack surface. Later reporting noted the feature can also impede some forensic extraction methods against locked devices.
