WikiLeaks on Monday released more than 21,000 emails allegedly hacked from French President Emmanuel Macrons campaign team.
The whistleblowing website released the trove of leaked emails as a searchable archive. It came almost three months after the Macron campaign was hacked on the eve of his election, the Telegraph reported.
The organisation said it had confirmed the 21,075 emails were sent or received by addresses associated with the campaign by checking the "domain keys" used to sign emails. It published a further 50,773 emails it could not verify.
In total, the leak included 71,848 emails, 26,506 attachments and details of 4,493 unique senders, the report said.
The Macron campaign announced that it had been hacked on May 5, just days before his run-off victory over Marine Le Pen.
The Macron campaign had previously blamed Russian interests for the hacking and cybersecurity researchers linked the attack to a group known as APT28 or Fancy Bears, the group believed to have hacked the US Democrats last year and which is often linked to the Kremlin.
Assange's network said the emails had been verified through its DKIM system.
