The number of individuals affected is not known, and no further details on the volume or specific contents of the material have been released publicly. This listing raises questions for anyone whose information may have been held by the company in the course of its operations, as the exposure of internal records can affect both personal privacy and ongoing business activities.

What happened

The incident was reported on March 7, 2026, when AiLock added Netwerk NV to its leak site. The group states that internal files were exfiltrated during a ransomware attack. No information has been made public about the timing of the intrusion itself, the scale of the data taken, or whether any material was later published.

Who is AiLock?

AiLock is a ransomware group that publicly lists organizations it claims to have targeted. Such groups commonly encrypt systems to disrupt operations and copy data to pressure victims into payment. Their listings serve as an initial claim of access; independent confirmation of the underlying events is not always available at the time of the announcement.

About Netwerk NV

Netwerk NV forms part of the Korevaar Group and provides services that include container cleaning, waste management, and pest control. Companies operating in these areas routinely collect records related to client contracts, site visits, regulatory compliance, and equipment maintenance. A breach at such an organization can therefore touch both commercial information and details connected to the individuals or businesses that use its services.

What was likely exposed

The only detail released is that internal files were allegedly exfiltrated. The exact categories of data contained in those files have not been disclosed. Organizations of this type commonly store operational logs, customer correspondence, billing records, and employee documentation, but whether any of these were among the material taken remains unconfirmed.

The real-world impact

Exposure of internal files can lead to follow-on misuse of any personal or commercial information they contain, such as attempts at fraud or targeted phishing. For the organization, the incident may result in operational downtime, costs associated with investigation and recovery, and potential regulatory scrutiny depending on the jurisdictions involved.

Were you affected?

Individuals who have interacted with Netwerk NV or the Korevaar Group can take straightforward steps to limit possible harm. Monitoring bank and credit accounts for unusual activity provides an early alert to misuse. Enabling multi-factor authentication on important online accounts reduces the value of any credentials that may have been taken.

• Review recent statements from financial institutions and service providers for unrecognized entries.
• Change passwords for any accounts linked to the organization and enable two-factor authentication where available.
• Request a copy of your personal data from the company if you believe it holds records about you.
• Use a free exposure scan of your email address against known breach datasets to check for prior appearances.
