National Office for centralized procurement Listed by siegedsec Ransomware Group: Ransomware Claim — What’s Alleged & What To Do

On 9 December 2023, the National Office for Centralized Procurement, a Romanian government body, was listed by the group known as siegedsec as the victim of a ransomware attack in which internal files were claimed to have been exfiltrated. The number of people affected remains unknown, and public detail on the precise scope and method is limited.

The listing itself constitutes an unverified claim by the group. What is confirmed in available reporting is only that the organisation appeared on the group's leak site in connection with asserted data theft. For an entity that manages centralised public purchasing, any confirmed compromise of internal material carries clear operational and privacy implications, even when the full contents stay undisclosed.

What happened

According to the reported facts, the National Office for Centralized Procurement was listed by siegedsec on 9 December 2023. The group described the incident as a ransomware attack in which internal files were allegedly exfiltrated. No further technical details—such as the initial access vector, the duration of any intrusion, the volume of data taken, or whether systems were encrypted—have been made public. The number of individuals affected is recorded as unknown.

Public reporting summarises the victim simply as a Romanian government organisation. No independent confirmation of the group's claims, no official statement from the office detailing the incident, and no disclosure of specific file counts or categories beyond “internal files” appear in the available record. Timing beyond the listing date, scale, and exact method therefore remain undisclosed.

The group behind it: siegedsec

Siegedsec is a threat actor that has operated in the public eye for several years, typically combining elements of hacktivism with data-leak and ransomware-style tactics. The group has historically claimed responsibility for intrusions against government, educational and commercial targets, often publishing stolen material on leak sites or Telegram channels to amplify pressure or political messaging. Its operations have frequently emphasised the exfiltration of internal documents rather than solely encryption for ransom, though ransom demands have featured in some campaigns.

Well-documented prior activity includes claims against public-sector entities in multiple countries, with the group sometimes framing its actions in ideological terms. In the present case, the sole concrete assertion tied to this victim is the leak-site listing itself: siegedsec claims to have conducted a ransomware attack and to have taken internal files from the National Office for Centralized Procurement. No additional statements attributed specifically to this incident—such as sample file releases, ransom amounts, or deadlines—are contained in the facts provided. The listing should therefore be treated as an unverified claim pending any independent corroboration.

National Office for Centralized Procurement and its sector

The National Office for Centralized Procurement is a Romanian government institution responsible for coordinating and executing large-scale public purchasing on behalf of state entities. Organisations of this type sit at the centre of public-sector supply chains: they manage tenders, contracts, supplier databases, pricing information and related administrative records. Their work touches ministries, agencies and, indirectly, the companies and citizens who interact with government procurement processes.

Because centralised procurement offices handle sensitive commercial and operational data, a breach can affect not only the institution’s own staff but also external suppliers, bidding parties and other public bodies that rely on the same systems. In the Romanian context, such an office forms part of the broader machinery of government administration; any compromise therefore raises questions about the integrity of procurement records and the confidentiality of information shared with or by the state. The consequential nature of the sector does not, however, establish negligence or state the group’s claims; it simply explains why the listing attracted attention.

What was likely exposed

The facts state only that internal files were exfiltrated in a ransomware attack. No inventory of those files, no confirmation of personal data, financial records or classified material, and no count of affected individuals have been disclosed. Exact contents therefore remain unconfirmed.

Organisations performing centralised public procurement typically hold categories of information that could, in principle, be present among internal files. These commonly include:

• Administrative and personnel records relating to staff and contractors
• Tender documentation, bid evaluations and contract awards
• Supplier contact details, commercial terms and pricing data
• Internal correspondence, procedural manuals and operational planning material
• System logs or configuration data associated with procurement platforms

None of the above should be read as confirmed contents of this incident. They illustrate only what such an office ordinarily processes. Until official notification or verified samples appear, any assertion about specific data types beyond the generic “internal files” would be speculative.

Why it matters

For individuals whose information might appear in internal government files—employees, contractors or external contacts—the principal risks are identity misuse, targeted phishing and unsolicited contact that leverages knowledge of procurement relationships. Even limited personal details can be combined with other breach data to increase credibility of social-engineering attempts.

For the organisation itself, exposure of internal procurement material can undermine competitive tendering processes, reveal negotiating positions, or create opportunities for fraud against public funds. Supplier relationships may be strained if commercial terms become public, and other government bodies that share systems or data with the office could face secondary exposure. Because the number of people affected is unknown and the precise files remain undisclosed, the practical scale of these risks cannot yet be quantified; the potential impact, however, is inherent to the nature of the data such an office holds.

There is no public indication that the listing has been accompanied by confirmed widespread identity theft or financial loss tied directly to this event. The matter remains at the stage of an attributed claim requiring further verification and official response.

Were you affected?

If you have worked for, contracted with, or supplied goods or services to the National Office for Centralized Procurement, or if you have otherwise shared personal or commercial information with Romanian centralised procurement processes, treat the possibility of exposure as open until clearer information emerges. Practical first steps include monitoring financial and email accounts for unusual activity, enabling multi-factor authentication where available, and being alert to unexpected messages that reference procurement matters or claim to come from government offices.

You can also run a free exposure scan of your email address to check whether it has already appeared in known breach datasets. Official notifications, if any are issued by the organisation or Romanian authorities, should be followed promptly; until then, remain cautious with unsolicited requests for further personal data and retain records of any suspicious contact.
