When environmental data was subjected to a data breach at the end of August, the hackers came across personal information about hundreds of thousands of Swedes.These include social security numbers, telephone numbers, email addresses, and residential addresses, says TV4. Now the hacker group DataCarry has taken on the attack.The group threatens to publish the information on Sunday. - They are looking to make money, says cyber security specialist Karl Emil Nikka to TV4. "Can only deeply regret" In a so -called ransomeware attack, data is "kidnapped and encrypted data, which means that the user - for example a municipality - cannot access it. The hacker group requires money in Bitcoin so as not to leak the information on Darknet.But you can make money even if the blackmail fails, as criminals can buy the information and use them for fraud attempts. Karl Emil Nikka tells TV4 that the hacker group "most likely" will be serious about the threat and publishing the information.Thus, there is an increased risk of net fishing attacks against hundreds of thousands of Swedes.Those affected should be extra vigilant on strange or unexpected emails, sms and telephone calls. Environmental Attorney CEO Erik Hallén writes in an email to the Gothenburg Post: "This is a new step in the attack on us. I can only deeply regret. We follow the development carefully to be able to act based on what the threat actor chooses to do." He also writes that environmental data, after advice from both security experts and police, has not been in contact with the hacker group. Read more: Personal data leaked within the City of Stockholm
