The US military operation plan against Yemen's Houthi forces was leaked through an encrypted chat group, raising significant concerns about cybersecurity and information handling.
The leak was confirmed by the White House, involving the US Secretary of Defense Pete Saxon.
The group chat included a journalist from The Atlantic, which led to the exposure of the operation.
Despite the leak, no immediate damage was reported, but it sparked a significant media and public interest.
The Atlantic's editor, Jeffrey Goldberg, received an unexpected invitation to the chat group.
The operation's details were known to Goldberg two hours before the attack on the Houthi forces.
The chat platform used was Signal, known for its encryption.
The occurrence has been linked to a possible mistake by a US government official.
There is speculation about whether the inclusion of Goldberg was intentional or accidental.
The incident highlights the vulnerability in handling classified information.
