“An investigation was opened today into charges of fraudulent access to an automated data processing system” but also fraudulent maintenance, introduction of data, fraudulent modification of data, fraudulent extraction of data and obstruction of the operation of such a system , said the public prosecutor.

This piracy comes eight years almost to the day after the attacks that decimated the editorial staff of Charlie Hebdo and while the newspaper finds itself at the heart of a diplomatic controversy after the publication Wednesday of cartoons on the Iranian regime deemed insulting by Tehran.

From the same source, the investigations were entrusted to the police officers of the internal intelligence (DGSI) and the Central Office for the fight against crime linked to information and communication technologies.

According to a source familiar with the matter, there was an “attack on the commercial website and defacing of the homepage”, but without “any significant claim” at this stage. "The investigation is starting," it added.

“Data would be on sale, this must be verified”, also indicated this source, while Europe 1 mentions in particular personal information concerning “several thousand subscribers”.

Thursday afternoon, the website of the satirical weekly was accessible, but not its shop.
