... John needs to change his password'

Hillary Clinton's campaign thought the email used to hack John Podesta's email account was real, and helped the attackers by telling the campaign chief to change his password immediately.

The revelation was included in the latest hacked emails released by Wikileaks.

A chain of emails shows Podesta received an email from, 'no-reply@accounts.googlemail.com', telling him that someone in the Ukraine tried to sign into his account.

Hillary Clinton's campaign thought the email used to hack John Podesta's email account was real, new documents reveal

'Someone has your password. Hi John. Someone just used your password to try to sign in to your Google Account,' the email read.

'Google stopped this sign-in attempt. You should change your password immediately.'

It then had a link Podesta could use to change his log-in information.

The email was then forwarded by Podesta's chief of staff Sara Latham to the campaign's IT department.

Hillary Clinton campaign IT Helpdesk Manager Charles Delavan (left) said the email was real and that Podesta needed to change his password. That advice was then forwarded to campaign official Milia Fisher (right)

Charles Delavan responded to a question about the initial email, saying it was 'legitimate' and that Podesta needed to change his password 'immediately'

After being told the original email was legitimate, Milia Fisher was told to change Podesta's email

IT Helpdesk Manager Charles Delavan replied: 'This is a legitimate email. John needs to change his password immediately, and ensure that two-factor authentication is turned on his account.

'It is absolutely imperative that this is done ASAP.'

Latham then sent Podesta and another campaign official, Milia Fisher, an email that read: 'the gmail one is REAL'.

Wikileaks has now released more than 35,000 of Podesta's emails.
