Suspected Cyberattack Disrupts Helsingborg Amidst NATO Meeting

On May 21, 2026, a suspected cyberattack caused significant disruptions in Helsingborg and surrounding areas, coinciding with the ongoing NATO meeting in the city. Payment systems experienced major issues, particularly affecting Nets, a key payment service provider, which reported operational disruptions though did not confirm a cyberattack. Mobile networks also faced some disturbances, with reports extending to Copenhagen, but it remains unclear if the problems are connected.

Authorities including the southern Sweden police and the Swedish Security Service (Säpo) are closely monitoring the situation but have not officially classified it as a cyberattack or a police matter. Peter Glüsing, Nets' press chief, noted, “There is nothing new right now, but we will obviously inform when we have more information.” Meanwhile, Säpo acknowledged payment system problems but refrained from commenting on potential cyberattack links. The Defence Radio Institute (FRA) mentioned that cyberattacks are a common daily occurrence in Sweden and typically do not confirm every incident to avoid aiding perpetrators.

The police also warned about potential disinformation and cyber threats connected to the NATO meeting, which draws prominent political figures such as Mark Rutte and Marco Rubio. NATO officials directed inquiries about any connection between the meeting and the cyber disruptions to the Swedish foreign ministry. The community's awareness of NATO was recently surveyed, highlighting the event's significance and the importance of accurate information.

The situation is evolving as authorities continue to investigate and gather more information.
