aditusbr.com Listed by lockbit5 Ransomware Group: Ransomware Claim — What’s Alleged & What To Do
aditusbr.com was listed by the LockBit5 ransomware group on 21 January 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 verify their status and act on any advisories issued.
What happened
The only public record of the event is the lockbit5 listing itself. It asserts that files were removed from aditusbr.com systems as part of a ransomware attack. No date of intrusion, volume of data, or method of access has been disclosed. The organisation’s response and any law-enforcement notification remain unreported.
Who is lockbit5?
Lockbit5 is the current iteration of the LockBit ransomware operation, a group that has conducted hundreds of intrusions since 2019. The group typically gains initial access through phishing, compromised remote-desktop services or supply-chain weaknesses, then deploys encryption while also copying selected files. Its public listings function as pressure tactics, threatening to release stolen material unless a ransom is paid. Earlier versions of the operation have targeted organisations in finance, manufacturing and professional services across multiple countries.
Who is aditusbr.com?
Aditusbr.com operates as an independent consulting firm that has worked with investors since 2011. Firms of this type routinely handle financial models, due-diligence documents, client correspondence and regulatory filings. Because such material often contains non-public information about investment decisions and counterparties, any confirmed exfiltration would affect both the firm and the entities it advises.
What was likely exposed
The listing refers only to “internal files exfiltrated in ransomware attack.” No inventory of file types or data categories has been published. Organisations in this sector commonly store client identifiers, financial projections, contract terms and communication records, yet the precise contents allegedly taken from aditusbr.com have not been verified.
Why it matters
Even without a confirmed count of records, the removal of internal files from a firm that handles investor-related material can create downstream exposure for clients and counterparties. Stolen documents may contain details useful for targeted fraud, market manipulation or further social-engineering attacks. The absence of disclosed numbers leaves affected parties without a clear basis for assessing their individual risk.

Publicly posted by lockbit5 — 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.
