Last week, several Swedish authorities and companies were subjected to a hacker attack, a so-called overload attack.
Among other things, svt.se was affected.
Shortly afterwards, the hacker group Anonymous Sudan took responsibility for the attack, which they believe is a protest against the Koran burning in Stockholm.
SVT Nyheter has been in contact with the hacker group via Telegram.
During Tuesday, the hackers warned that Denmark is next in line.
At 14:51 they wrote in the chat, translated from Arabic:
SVT: Which country will you attack next?
The hacker group: Denmark.
Four hours later, the hacker group published a message on its official channel that Denmark would be attacked.
Several Danish airports have now suffered from problems, reports DR.
Anonymous Sudan has claimed the attack.
According to IT experts, the warnings mean that it is very likely that the people behind the account are also behind the attacks.
The expert: Acting in the interests of the Kremlin
However, experts believe that there are many indications that Russia is behind the attacks.
IT security expert Marcus Murray calls it an information operation.
- They have an anti-NATO agenda and act in the interests of the Kremlin.
They choose things that attract a lot of attention.
And the media is a very important component for reaching out, he says.
Attacking Danish sites is a sham, according to Marcus Murray.
- If they want to convince us that it has nothing to do with the NATO issue, they will try to find a suitable target connected to the Koran burning.
Then it could be Denmark, he told SVT on Tuesday.
