BC3 Tecnologia Listed by nova Ransomware Group: Ransomware Claim — What’s Alleged & What To Do
BC3 Tecnologia was listed by the nova ransomware group on May 30, 2026, after internal files were exfiltrated in a ransomware attack. An undisclosed number of people may have been affected; anyone connected to the organisation should check for any impact and take appropriate steps.
Inside the incident
The only public information comes from the group’s listing on its leak site. It asserts that files were taken from BC3 Tecnologia and offers limited samples, including a directory tree and two files that the group says it will decrypt without payment if the company contacts its support channel. No date of intrusion, duration of access, or volume of data has been disclosed by either the group or the company. The number of individuals potentially affected remains unknown.
The group behind it: nova
Nova is a ransomware operation that maintains a public leak site where it lists organizations it claims to have targeted. The group typically publishes a sample of stolen material and offers to decrypt a small number of files at no cost, a tactic intended to prompt direct contact. Its listings are presented as claims by the group; independent confirmation of the underlying intrusions is not always available at the time of publication.
BC3 Tecnologia and its sector
BC3 Tecnologia operates from Brazil and supplies enterprise resource planning software, notably the KRP system, to companies in the corrugated packaging and cartonage industry. Firms in this sector manage production schedules, inventory, customer orders, and supplier relationships for packaging materials used across manufacturing and distribution chains. A compromise at a software provider in this niche can therefore touch operational records belonging to multiple downstream businesses.
What data was at risk
The listing refers only to “internal files.” The precise categories of information contained in those files have not been published. Organizations that develop and support ERP platforms commonly hold customer configuration data, license records, support logs, and internal business documents; however, the exact contents of the material claimed by nova remain unconfirmed.
Why it matters
ERP systems used by packaging manufacturers often contain details of production volumes, pricing agreements, and delivery schedules. Exposure of such records can create competitive or operational risks for the affected companies and their clients. Because the scale of the exfiltration is still unknown, the extent of any downstream impact cannot yet be assessed.
What to do if you're exposed
Individuals or organizations that believe their information may be involved should monitor accounts for unusual activity, enable multi-factor authentication where available, and review any vendor communications from BC3 Tecnologia. A free exposure scan of an email address against known breach data can provide an initial indication of whether credentials or other details have appeared in public listings.

Publicly posted by nova — unverified claim, pending independent verification
Breach listings — particularly those originating from ransomware or leak sites — are third-party claims that may be unverified, incomplete, or inaccurate. A listing does not by itself confirm that a breach occurred or that any specific data was exposed. Severity is an automated assessment, not a definitive rating. Verification status is shown where available.
Attributions to threat groups and methods reflect public reporting and, in some cases, unverified claims made by the groups themselves; they may be incomplete or later revised.
