According to the newspaper, Sweden's national police have added crime-ridden areas in Uppsala, Landskrona and Borås, as well as new problem areas in Malmö, Stockholm and Gothenburg.
Police told Swedish Radio that the number of areas had increased but would not confirm the details of DN's report.
If confirmed, the new list will bring the number of especially vulnerable areas to 23 from the 15 named in a 2015 police report.
Linda Staaf, head of the intelligence department at the police's national operations department Noa, told the newspaper that the increase was a result of better intelligence rather than a worsening in the situation in these areas.
"In comparison to the last report we now have more knowledge and a better picture," she said.
The new areas include Gottsunda i Uppsala, Karlslund in Landskrona, Norrby and Hässleholmen/Hulta in Borås, Fittja and Alby in Stockholm, Tynnered/Grevegården/Opaltorget in Gothenburg, and Nydala/Hermodsdal/Lindängen in Malmö.
After police released its 2015 report, the international right-wing media began describing the 15 areas as police "no-go zones", a description police reject.
Erik Åkerlund, chief of police in Botkyrka, southern Stockholm, one of the areas, said rather than being places police fear to enter, the areas were places where they felt they were needed most.
"For me it's more like 'go go zones'," he told Radio Sweden in February. "It's where we work."
