​​​​bettininformatica - suporteon Listed by nova Ransomware Group: Ransomware Claim — What’s Alleged & What To Do

On April 16, 2025, the ransomware group known as nova listed Bettin Soluções em Informática, operating under the domain bettininformatica.com.br, among its claimed victims. Public detail remains limited: the listing indicates that internal files were exfiltrated in a ransomware attack, yet the number of people affected is unknown and no further confirmation of the incident has been independently verified. For a technology services firm based in Marília, São Paulo, Brazil, any such claim raises immediate questions about the security of systems that support clients and the potential exposure of operational data.

What is known so far rests solely on the group’s leak-site entry and the sparse accompanying description. The organisation provides computer maintenance and related IT services; a breach of its internal systems could therefore touch both its own records and those of the businesses and individuals that rely on it. Until more information surfaces, the scale, method and precise contents of any compromise stay unconfirmed.

Breaking down the breach

The incident came to light through a listing posted by the nova ransomware group on April 16, 2025. According to that listing, internal files belonging to Bettin Soluções em Informática were exfiltrated during a ransomware attack. No public statement from the company has been recorded in the available facts, and the number of individuals or systems affected is listed as unknown. Timing of the intrusion itself, the initial access vector, and any ransom demand remain undisclosed. The only concrete claim is that data left the organisation’s control; whether encryption of production systems also occurred, or whether any files have been released, has not been established beyond the group’s assertion.

The group behind it: nova

Nova is a ransomware operation that follows the now-familiar double-extortion model: after gaining access to a network, operators encrypt systems and simultaneously copy data, then threaten to publish the stolen material if payment is not made. The group maintains a dedicated leak site where it posts victim names, sample files and, in some cases, full archives once deadlines pass. Public reporting on earlier campaigns shows that nova has targeted organisations across multiple sectors and geographies, typically relying on phishing, compromised credentials or unpatched remote-access services for initial entry. Once inside, the group moves laterally, escalates privileges and stages data for exfiltration before deploying the encryptor. In the present case the group claims to have listed Bettin Soluções em Informática after extracting internal files; that claim has not been independently corroborated by the company or by third-party forensic reports available in the public record.

Bettin Soluções em Informática and its sector

Bettin Soluções em Informática is a technology company headquartered in Marília, in the Brazilian state of São Paulo. Its website, bettininformatica.com.br, describes services that include computer maintenance and related IT support. Firms of this type typically manage hardware, software, networks and help-desk operations for local businesses, professional offices and sometimes municipal clients. Because they hold administrative credentials, configuration files, client inventories and remote-access tools, they occupy a privileged position in the digital supply chain of the organisations they serve. A compromise at such a provider can therefore extend beyond the firm’s own walls, potentially affecting every customer whose systems or data the provider touches. In Brazil’s growing regional IT-services market, smaller and mid-sized providers like Bettin often serve as the primary technology partner for companies that lack large in-house security teams, making the integrity of their own infrastructure especially consequential.

What data was at risk

The only data type named in the available facts is “internal files” said to have been exfiltrated. No inventory of those files, no count of records, and no classification of sensitivity have been published. Organisations that supply computer maintenance and IT support commonly store client contact lists, service contracts, network diagrams, software licence keys, remote-access credentials, billing records and internal correspondence. Employee personal data—such as identification numbers, payroll details and contact information—may also reside on the same systems. Because the precise contents remain unconfirmed, it is not possible to state which of these categories, if any, were among the files taken. The absence of further disclosure means that both the company and any potentially affected parties must treat the full scope of exposure as unknown until additional evidence appears.

What's at stake

For individuals whose information may have been held by Bettin Soluções em Informática, the practical risks include identity misuse, targeted phishing and unsolicited contact that leverages knowledge of their relationship with the firm. Even limited internal documents can reveal enough context for social-engineering attacks against clients or staff. For the organisation itself, the stakes include operational disruption if systems were encrypted, reputational damage among the local businesses that depend on its services, and potential regulatory scrutiny under Brazil’s General Data Protection Law (LGPD). Clients may face secondary exposure if credentials or configuration data that grant access to their own networks were among the exfiltrated material. Until the company or independent investigators clarify what was taken, both the firm and its customers must operate under the assumption that some internal material is in unauthorised hands and could be misused.

What to do if you're exposed

Anyone who has used Bettin Soluções em Informática for IT support or whose organisation is a client should treat the listing as a prompt for basic hygiene rather than confirmed personal compromise. Change passwords on any accounts that may have been managed or accessed through the provider, enable multi-factor authentication wherever it is available, and monitor financial and email accounts for unusual activity. Review recent correspondence for signs of phishing that reference the company or its services. Because the exact data set remains undisclosed, a free exposure scan of your email address against known breach collections can help determine whether your address has already appeared in other public dumps; such a check does not prove involvement in this incident but offers a practical starting point for personal vigilance. If you receive direct notification from the company, follow the guidance it provides and consider placing a fraud alert with Brazilian credit-protection services if sensitive personal identifiers are later confirmed to have been involved.
