The Centre for Cyber Security has released a warning that there may be a risk of hacker attacks against websites following the Copenhagen shootings.

“There are often simple defacements or DDoS attacks against government and non-government websites, including media websites,” the centre said.

DDoS attacks are a type of attack whereby a website is inundated with a constant stream of queries that basically locks down a website, thus preventing legitimate users to access the site.

Pushing an agenda
The centre’s research shows that cyber attacks can often happen to push forward a political statement, which they call a defacement attack.

Such an attack occurs when hackers hijack government and company websites or their social media accounts, such as Twitter or Youtube, to display political slogans and messages.

The centre has said they have no knowledge that a real cyber attack is imminent, but recommend that website owners “exhibit vigilance” and assess their IT security situation, including strengthening passwords.
