Her Song Contest Eurovision appears to have been targeted by hackers looking to influence voting for the final song selection in the qualifier.
Votes began yesterday to flood the Melodifestivalen application after Jon Henrik Fjällgren's show, forcing the organizers of the contest to zero votes.
Mananger leader Christel Tholse Willers called the wave of votes "extreme overload".
"We are investigating her attack. Our servers are set for a very heavy load, but what hit us was abnormal and extreme," Willers said.
From 3,7, millions of viewers watched their qualifiers Eurovision, about half a million of them used the application, increasing votes compared to last year by about 400%. Both voice (voice) and SMS are still the preferred 1,5 million viewer methods.
Safety testing by researchers claimed that Melodifestivalen was vulnerable to attacks.
The application that costs £ 100.000 requires users to connect via Facebook or Google Plus, or subscribe using their mobile numbers.
