Fine Gael's website has been hacked and details of thousands of visitors to their website have been made available to media organisations.
The hackers posted a message on the site saying 'Nothing is Safe', and emailed a database to media organisations containing contact details of almost 2,000 people who had contacted the website.
An international cyber attack forced its closure.
Speaking to RTÉ News Pascal Donohoe of Fine Gael said that the attackers obtained some details of thousands of visitors to the website. The Fine Gael party say that it is unsure why it was a target for the attack. Fine Gael is now working in partnership with the Data Protection Commission and An Garda Síochána to investigate the matter.
Responsibility for the attack lies with a group called 'Anonymous', who also struck Mastercard and Visa websites the previous month in protest at global attempts to silence Wikileaks.
Kevin Doyle, political correspondent for the Evening Herald said it was very embarrassing for Fine Gael, as the new website had been launched as part of their election strategy.
