However, there is no specific threat directed at Sweden at the moment.
"This is a way to increase vigilance in a tricky time," says Ola Billger, head of communications at FRA, to TT.
According to information provided to TV4 Nyheterna, Swedish police have gone on alert in an international operation and are guarding critical facilities. Several authorities and police units throughout the Nordic region have also reportedly gone on alert. The Swedish Civil Defence Agency (MCF) and the Swedish Energy Agency both state that they are aware of the information.
FRA says it has recently urged actors in Sweden's energy sector to be more vigilant.
"We did that last Friday," says Ola Billger.
Be vigilant
The background to the call, according to FRA, is attacks directed at the Polish energy sector at the end of December.
In the middle of last year, Poland was subjected to a massive cyberattack targeting the energy sector. The attack was stopped, but the Polish government considered the attack "serious" and pointed to groups with links to Russia as responsible.
"In this case, we think there is reason to be extra vigilant in the energy sector, because we have seen how other countries' energy sectors have been subjected to destructive cyberattacks."
"No specific threat"
Is there any specific threat directed at Sweden right now?
"No," says Ola Billger.
"This is a way to raise the guard in Sweden, but it's not the same as saying there is an attack going on right now."
In its annual report, Must has warned of an increased risk of Russian saboteurs, especially linked to Sweden's military support for Ukraine.
