Cyberattacks on infrastructure seem to be becoming a part of daily life. The latest one hit the Romainian water management authorities, taking around 1,000 computers down, affecting 10 of the country's 11 regional offices with hostile data encryption (ransomware).

No criminal group has yet claimed the action, but the attackers left a message demanding the institution contact them in seven days. The affected management systems include email, web services, databases, and Geographic Information Systems. Predictably, Windows workstations and domain name servers were also hit.

Just last week, Denmark formally accused Russia of two cyber-attacks on its infrastructure. In 2024, the pro-Russian Z-Pentest hit Danish water control systems, managing to change water pressure and burst three pipes in Køge, south of Denmark, leaving 500 homes without water for a few hours. And in 2025, another pro-Russian group NoName057(16) executed a distributed denial-of-service attack on Danish websites ahead of elections. Germany took a similar stance earlier this month, attributing an attack on Germany's air traffic control systems in 2024 to the Russian Fancy Bear group.

    A country with properly prepared secret services shouldn't have trouble mitigating this. Romania is also home to Bitdefender. One would think they'd get involved with securing vital systems in the country.
