Hackers have attacked websites belonging to exchange operators Nasdaq and BATS over the last 24 hours, causing ongoing disruptions for those trying to use the sites, according to Reuters.

On Tuesday afternoon, only the website banner was visible during repeated attempts to access the site.

A Nasdaq OMX Group spokesman told Reuters that the company had been facing a denial-of-service attack (DOS) since late on Monday, but said they had not located the origin of the attack and were unable to say when it would be resolved.

"The website wasn't hacked, nobody got any information. What they did was try to block access for our users," said Nasdaq spokesman Joseph Christinat.

The Nasdaq's websites are separate from their trading systems and Christinat said the breach had not affected trading in any way.

"We experienced intermittent service disruptions on our corporate website and we are working to resolve the issues," he said.

A BATS spokesperson told Reuters that the company was affected by a denial of service incident. "Our trading systems were not affected and there were no exchange customer disruptions associated with the incident," the exchange said in a statement.

Both the Nasdaq and the New York Stock Exchanges have previously been the victims of cyber-attacks.

Hackers infiltrated the Nasdaq's computer systems in 2010 and installed malicious software that allowed them to spy on the directors of publicly held companies, Reuters reported last year.

In October 2011, the NYSE's website was inaccessible for 30 minutes, according to an internet monitoring company, following a video posted on You Tube by hacker group Anonymous.

It said the NYSE website would be "erased from the internet" in sympathy with the then-ongoing "Occupy Wall Street" protests in Lower Manhattan.

The digital world has become nebulous & precarious. Global regulations and policing is mandated to inhibit such attack.
