The reporting included photos and details from a top secret internal document proposing new abilities to “proactively disrupt and covertly remove” onshore threats by “hacking into critical infrastructure”.
The federal police confirmed the execution of a search warrant on Tuesday as part of an “investigation into the alleged unauthorised disclosure of national security information”.
In a statement, the police said they would allege the disclosure of “these specific documents undermines Australia’s national security”.
“No arrests are expected today as a result of this activity,” the statement said.
