Bevolkingsonderzoek Nederland, or BVO NL, a analysis company which oversees the nationwide Inhabitants Screening Netherlands packages for screening three kinds of most cancers – breast, colon and cervical – in an announcement Friday mentioned that Scientific Diagnostics NMDL, the lab that handles this system’s cervical most cancers screenings, has knowledgeable the company that one other 230,000 sufferers have had their data “leaked” within the lab’s current hack (see: Knowledge Theft from Dutch Most cancers Screening Lab Impacts 485,000).

Ransomware-as-a-service gang Nova had first threatened in July on its darkish web site to leak the lab’s stolen knowledge. Nova is a relative newcomer that some safety researchers say distributes the RALord ransomware to encrypt recordsdata, exfiltrate delicate knowledge and use double extortion techniques to stress victims.

Since then, in posts on the gang’s darkish website on Aug. 17 and Aug. 22, Nova seemed to be bickering with Scientific Diagnostics and its dad or mum firm, Eurofins Scientific, over negotiations pertaining to fee “offers” to forestall additional leakage past samples of the lab’s stolen knowledge.

Scientific Diagnostics in an Aug. 18 submit on its web site in regards to the incident acknowledged threats by the attacker, however did not identify the gang.

“Beforehand, we indicated that now we have no indications that the attacker will proceed to leak the copied knowledge. We’re conscious of the truth that the attacker is as soon as once more threatening to leak copied knowledge. This new growth clearly has our consideration. As indicated earlier, we can not present additional data concerning sure particulars.”

Inhabitants Screening Netherlands made the choice to inform all sufferers “whose knowledge has ever been shared with the laboratory” since 2017 in regards to the hacking incident, including that “Scientific Diagnostics can not affirm that that is the total extent of the info breach,” Populations Screening Netherlands mentioned.

“We notice that this can be a very disagreeable message for individuals within the cervical most cancers screening. We’re very sorry that this has occurred. We’re speaking this now as a result of individuals must keep in mind attainable phishing and fraud.”

Inhabitants Screening Netherlands mentioned that along with Scientific Diagnostics, the company is engaged on finishing up cervical most cancers screenings with a number of different laboratories that haven’t been affected by the hack.

Scientific Diagnostics and Eurofins didn’t instantly reply to Info Safety Media Group’s requests for touch upon Nova’s claims, and for different particulars pertaining to the hacking incident.

Breach Particulars

Scientific Diagnostics within the discover on its web site in regards to the incident mentioned the data probably compromised within the hack contains identify, gender, date of delivery, tackle, particulars about the kind of examination and check outcomes, citizen service quantity – or BSN, particulars of the applicant and identify of well being insurer (see: ISMG Editors: Dutch Lab Hack Reveals Healthcare Safety Gaps).

“Acknowledged healthcare suppliers within the Netherlands are legally obliged to file and retailer the BSN of their sufferers. They use the BSN after they change knowledge about sufferers. That’s the reason the BSN was additionally within the leak at Scientific Diagnostics,” the lab mentioned.

The hackers gained unauthorized entry to a part of the IT surroundings of Scientific Diagnostics NMDL and Scientific Diagnostics LCPL, each situated in Rijswijk, the lab mentioned. “No different laboratories inside the community of Scientific Diagnostics Netherlands have been affected by this incident,” the lab mentioned.

“Regardless of fast detection and intervention, we all know that entry was gained to private knowledge of sufferers and referrers that had been saved on this a part of the IT surroundings. Sure private knowledge have additionally been copied.”

The lab additionally mentioned that Netherlands’ Public Prosecution Service has launched an investigation into the incident.

Relative Newcomer

Ransomware.stay, a weblog that displays cybercriminal gangs and their assaults, counts 37 Nova victims for the reason that group first surfaced in April 2025.

“Nova has emerged as a financially motivated ransomware-as-a-service operation, constructed across the RaLord ransomware household,” mentioned Jeremy Makowski, a Rapid7 safety researcher. “Whereas the group’s TTPs reveal a mature RaaS mannequin, its IOCs supply defenders actionable factors for detection.”

Nova’s encryptors are written in Rust and go away behind recordsdata with extensions comparable to “.ralord” or “.RNOVA”, alongside ransom notes labeled “README-Nova”, he mentioned.

The group directs victims to contact them by means of personal messengers like Tox or Session, as a result of they like to barter fee quite than present conventional fixed-payment directions, he mentioned. “We will additionally see from its public sufferer listings that Nova targets organizations throughout a number of sectors together with healthcare, IT, manufacturing, telecom, training and building, exhibiting an opportunistic and international focus.”

“Nova is the most recent model in an evolving lineage, so it is not a completely new actor. The group operates the RaLord ransomware, which is taken into account a successor or offshoot of the previous RA Group,” Makowski mentioned.

Nova is probably going both the dad or mum operator of RaLord or a rebranding initiative persevering with its growth and associates program, he mentioned.

“The group has structured its operations with a basic RaaS incentive system, providing associates a proportion of ransom proceeds, mirroring the strategy of different felony organizations.”

Up to now there isn’t a credible proof that Nova is linked to a nation-state, Makowski mentioned. “Whereas among the group’s infrastructure and communications could counsel Russian-speaking traits, that is inadequate to conclude that it’s state-sponsored. As an alternative, Nova matches the mannequin of a felony enterprise centered on revenue by means of extortion.”

Medical Lab Assaults

The cyberattack on a Dutch medical testing laboratory highlights the numerous cyber dangers going through medical laboratories worldwide, Makowski mentioned.

“For laboratories, the teachings are clear,” he mentioned. First, they need to assume that knowledge theft will happen and plan accordingly by means of segmented networks, strict entry controls, fast detection of intrusion and knowledge exfiltration makes an attempt, he mentioned.

Second, it is important that medical laboratories acknowledge that they’re notably weak attributable to their knowledge and regulatory worth, making them prime targets for extortion, he mentioned.

“Constructing resilience towards Nova-type assaults requires technical defenses to safe internet-connected techniques, monitoring for anomalous knowledge flows, isolation of laboratory devices and organizational preparation for transparency and restoration.”
