The contact details of over 1,400 security professionals have been accidentally sent out by McAfee.

The details of delegates at a recent conference in Sydney were sent on a bulk email and revealed demographic data collected during the registration process, as well as the full contact details of 1,408 people who attended or registered.

The details included names, company, job title, address, phone number and email of all those who attended. Details of the error were shown on an image hosted by Flickr, where delegates are thanked for their participation by APAC president Steve Redman, with an Excel file attachment that includes the personal details.

A follow-up email to recipients stated: “You may have been inadvertently sent information containing registration details from our recent security summit. This was sent in error and we therefore request that this information be deleted and we sincerely apologise for any inconvenience caused as a result of this."

A spokesperson from McAfee told iTnews that the company is uncertain as to how many people received the attachment in error. The spokesperson said: “McAfee managed to intercept this email before it was sent to all recipients, so it is uncertain how many recipients received the list.

“Due to a human error, the contact list for a seminar (held two weeks ago in Sydney) was mistakenly attached to a promotional email being sent to conference delegates. This contact list included common conference registration information but did not include any financial information.”
