Swede and Sour Data
Data breach at major Swedish software supplier impacts 1.5M
Hackers dump Swedes’ data as commenters split: ‘already public’ vs ‘fix the code’
TLDR: Hackers breached Miljödata, a key supplier to Swedish municipalities, with up to 1.5 million people’s data dumped online after a 1.5 Bitcoin demand. Commenters are split: some say much of this info is public in Sweden anyway, others want governments to fund secure coding like critical infrastructure.
Sweden woke up to a digital hangover: Miljödata, the IT supplier powering about 80% of municipalities, got hit. Attackers stole data, demanded 1.5 Bitcoin, and later the Datacarry gang posted a 224MB trove on the dark web. The state jumped in fast—CERT-SE and police investigating, privacy watchdog IMY saying up to 1.5 million affected, while Have I Been Pwned puts it closer to 870,000. Disruptions hit regions across the map, from Halland to Gotland to Karlstad. The plot twist? The comments section turned into a street fight. One faction is furious, pointing to risks for kids’ records and people with protected identities, and calling this a GDPR (Europe’s privacy law) nightmare. Another faction shrugs: in Sweden, lots of this stuff is already public—salaries, credit ratings, criminal history, addresses, even who owns which cars—so what’s new? Meanwhile, builders are catching heat: one commenter says governments must fund secure programming like roads and bridges—no more leaky code. There’s gallows humor too: 1.5 BTC got roasted as “used Volvo money,” while others argue “public” isn’t the same as “packaged for scammers.” IMY is zeroing in on Miljödata and key municipalities like Gothenburg next.
