The hacking group Anonymous Sudan set its sights on Sweden in May as the country made attempts to join NATO. The group targeted dozens of airports, hospitals, and banks in the country using DDoS attacks. The security breach wreaked havoc on Scandinavian Airlines’ websites, knocking them completely offline and disrupting Sweden’s national public broadcaster.
Mattias Wåhlén, who led an investigation into the hacks for Truesec, one of Sweden’s biggest cybersecurity firms, told Bloomberg at the time that Anonymous Sudan appears to be linked to a well-organized unit of Russians, who he says have a full understanding of local politics and social issues.
Katarzyna Zysk, a professor of international relations at the Norwegian Institute for Defence Studies in Oslo told the outlet, “This strategy of creating chaos is one of the major means Russia has been using against Sweden” to complicate its NATO application.
