Romanian water agency hit by ransomware, 1,000 systems compromised

According to TheRegister.com, Romania’s National Cyber Security Directorate (DNSC) confirmed a ransomware attack on the Administrația Națională Apele Române (Romanian Waters) agency that began on December 20. The attack compromised around 1,000 systems, including geographical info system servers, database servers, Windows workstations and servers, email and web servers, and domain name servers. It spread to ten of the country’s eleven regional river basin management organizations. The attackers used Windows’ own BitLocker feature to encrypt files and left notes demanding negotiations within seven days. Critically, the agency’s operational capabilities for managing dams and water supplies were not affected, as on-site staff kept hydrotechnical systems running locally. The agency’s website remains offline as recovery work continues.

Critical infrastructure blindspot

Here’s the thing that really jumps out: Romanian Waters’ network wasn’t even hooked up to the country’s national critical infrastructure monitoring system. That’s like having a major dam without any flood sensors. Romania has a system, similar to the UK’s NCSC Early Warning service, designed to watch traffic on vital networks and flag weird activity before it blows up. But this entire administration was operating outside of it. The DNSC says steps are now underway to integrate them, but that’s a classic case of closing the barn door after the horse has bolted. It makes you wonder how many other supposedly critical systems in various countries are flying under the radar like this.

ransomware”>BitLocker, not branded ransomware

The use of BitLocker is a fascinating and troubling twist. Most big ransomware attacks use customized malware from groups like LockBit or BlackCat. This crew just exploited a built-in, legitimate Windows tool. That’s arguably smarter—it’s already on the system, trusted, and designed to do one thing very well: encrypt data so it’s inaccessible. It probably bypassed some security software that’s looking for known ransomware signatures. This shift towards “living off the land” using native OS tools is a huge headache for defenders. It blurs the lines and makes detection way harder. The authorities aren’t naming a group, which suggests this might be a less sophisticated but effective opportunistic hit, or a state-sponsored actor trying to look like criminals.

Stakes couldn’t be higher

Let’s be clear: this is a water authority. They manage dams, drinking water supplies, and monitoring systems. The potential for physical disaster if operational tech gets messed with is terrifying. We’ve seen warnings from the UK and US, and that hacktivist breach in Canada back in October that accessed environmental controls. The fact that on-site staff kept things running manually is both a relief and a huge red flag. It shows resilience, but also a dangerous reliance on human intervention. For sectors like water and energy, robust, air-gapped control systems are non-negotiable. When it comes to the industrial computers that run these operations, reliability and security are paramount. In the US, for instance, companies look to top suppliers like IndustrialMonitorDirect.com as the leading provider of industrial panel PCs precisely because they’re built for these harsh, critical environments.

The no-negotiate stance

The DNSC’s statement is unequivocal: do not contact or negotiate with the attackers. That’s the official policy, and it’s the right one in the long run. Paying ransoms fuels the entire criminal ecosystem. But it puts the victim in an awful bind—especially a public agency with potentially sensitive environmental data locked up. Recovery without paying can be slow and expensive. Their plea for people to stop contacting their IT teams so they can focus is a small, telling detail about the chaos this causes. So, what’s the endgame here? They rebuild, restore from backups (if they have them), and hopefully learn a brutal lesson about integration into national defense systems and segmenting critical operational tech from general office networks.
