National Civil Service Commission of Colombia Listed by kazu Ransomware Group: Ransomware Claim — What’s Alleged & What To Do

People who have applied for public-sector jobs in Colombia, or who work in the civil service, may now face uncertainty about whether personal or professional information held by the National Civil Service Commission has been taken. When a government body that manages recruitment and personnel records is listed by a ransomware group, the practical stakes include possible exposure of identity details, employment histories, and contact data that could be misused for fraud or targeted scams.

Public reporting on 10 November 2025 stated that the Comisión Nacional del Servicio Civil (CNSC) had been listed by the kazu ransomware group, which claimed to have exfiltrated internal files. The number of people affected remains unknown, and independent confirmation of the full scope is not yet available.

What happened

On 10 November 2025 the National Civil Service Commission of Colombia was listed on the leak site associated with the kazu ransomware group. According to the listing, internal files were exfiltrated during a ransomware attack. No further technical details about the intrusion method, the precise date of the attack, or the volume of data taken have been disclosed in the available public record. The number of individuals whose information may be involved is listed as unknown. The group’s claim that data was stolen has not been independently verified in the reported facts, so it stands as an unverified assertion at this stage.

Inside kazu

kazu is a ransomware group that operates in the familiar double-extortion model used by many modern ransomware actors. Such groups typically encrypt systems and simultaneously copy data, then threaten to publish the stolen material on a dedicated leak site if a ransom is not paid. Listings on these sites serve as both pressure on the victim organisation and advertising of the group’s activity. Public reporting on kazu has described it as one of several ransomware operations that post victim names and sample claims of data theft. No specific statements made by kazu about the Colombian commission beyond the basic listing of the organisation and the claim of internal-file exfiltration are recorded in the facts available for this incident. As with other ransomware groups, any technical claims of encryption or data volume should be treated as assertions until confirmed by the organisation or independent investigators.

National Civil Service Commission of Colombia and its sector

The Comisión Nacional del Servicio Civil is Colombia’s national body responsible for overseeing the recruitment, selection and management of public servants. It runs merit-based competitions for government posts, publishes vacancy notices, manages application processes and maintains the regulatory framework that governs public employment. Its official portal is the primary channel through which citizens learn about civil-service openings and submit applications. Organisations of this type routinely hold large volumes of personal data belonging to applicants and current or former public employees, including identification documents, educational and professional histories, contact details and evaluation records. Because the commission sits at the centre of public-sector hiring, a compromise of its systems can affect trust in the fairness and security of government recruitment across the country.

What data was at risk

The only data category named in the public listing is “internal files” said to have been exfiltrated in a ransomware attack. Exact contents have not been disclosed. Bodies that manage civil-service recruitment typically store application forms, identity documents, academic credentials, employment histories, contact information and sometimes medical or financial details required for eligibility checks. Whether any of those categories were among the files claimed by kazu remains unconfirmed. Until the commission or forensic investigators publish a verified inventory, the precise nature of the exposed material cannot be stated as fact.

The real-world impact

For individuals, the principal risks are identity theft, phishing campaigns that exploit knowledge of job applications or employment status, and potential social-engineering attacks that reference genuine civil-service processes. Applicants who supplied sensitive documents may face longer-term concerns about secondary use of that information. For the commission itself, the incident raises questions about continuity of recruitment services, the integrity of ongoing selection processes and the need to notify affected parties once the scope is clarified. Public confidence in the fairness of government hiring can also be affected when the body that administers those processes appears on a ransomware leak site. No confirmed financial losses, operational outages or confirmed identity-fraud cases linked to this listing have been reported in the available facts.

Were you affected?

If you have applied for a public-sector post through the CNSC, or if you are a current or former civil servant whose records may be held by the commission, monitor official communications from the organisation for any formal notification. Watch bank and credit accounts for unusual activity, treat unsolicited messages that reference civil-service applications with caution, and consider placing fraud alerts with relevant credit bureaus if you believe sensitive identity data may have been involved. Readers can also run a free exposure scan of their email address to check whether that address has already appeared in known breach data sets. Any confirmed notice from the commission itself should take precedence over third-party claims.
