The website for the Liberal Democrats was hacked at the end of last week, with the front page redirecting to a YouTube protest about tuition fees.

A message stated: ‘remember the general election?', when referring to leader and deputy Prime Minister Nick Clegg pledged to phase out tuition fees over six years.

An investigation by the New Statesman found that the website is not the official website of the Liberal Democrats, but is registered to the address of the Liberal Democrat headquarters in Westminster.

The video was created by the National Union of Students (NUS) but it denied that it was responsible.

Paul Vlissidis, technical director at NGS Secure, part of NCC Group, said: “This is the latest in a long line of politically motivated hacks and reinforces the questionable track record political parties have when it comes to IT security. While this is obviously a prank intended to embarrass rather than be malicious, the ease at which political websites can seemingly be hacked does beg the question: what information is kept on political websites?

“Once a server is compromised, all the information on it is at risk of exposure to hackers and if party member information sits on the server, it may necessitate a report to the information commissioner.

“Both Labour and The Conservatives have also been victims of well-publicised attacks in the past and until political parties take IT security seriously, this won't be the last hack that causes embarrassment.”
