The Holy Souls group known as NEPTUNIUM has claimed to have stolen the personal information of over 200,000 customers of the French satirical magazine Charlie Hebdo

The group released a spreadsheet containing usernames, phone numbers and home and email addresses as proof. The leak could put customers at risk by making them targets for extremist organizations.

“We believe this attack is a response by the Iranian government to a cartoon contest held by Charlie Hebdo. A month before they carried out their attack, the magazine announced that it would hold an international contest for cartoons ‘mocking’ Iran’s Supreme Leader Ali Khamenei,” Microsoft said in a detailed blog about the attack.
