erstransportes.com.br Listed by lockbit5 Ransomware Group: Ransomware Claim — What’s Alleged & What To Do
erstransportes.com.br was listed by the LockBit5 ransomware group on April 26, 2026, after internal files were exfiltrated in a ransomware attack. An undisclosed number of people may have been affected; check the listing and take appropriate steps if your information appears.
Breaking down the breach
The only confirmed public information is the listing itself and the brief description that internal files were taken. No date of the initial compromise, no volume of data, and no confirmation of encryption or ransom demands have been made public. The organisation has not issued a statement on the incident, and independent verification of the data’s authenticity has not occurred.
The group behind it: lockbit5
LockBit is a ransomware operation that has conducted numerous intrusions since at least 2019. Its standard approach involves encrypting systems and copying files, then threatening to publish the copied material if a ransom is not paid. The group maintains a leak site where it lists victims and sometimes posts samples of claimed data. Listings on this site represent the group’s assertions; they are not independently verified unless corroborated by the affected organisation or law-enforcement findings.
Who is erstransportes.com.br?
ERS Transportes began operations in 2003 and specialises in cargo movement using container-handling equipment. The company operates within Brazil’s logistics sector, handling freight that moves between ports, warehouses and industrial sites. Organisations of this type routinely maintain records relating to shipments, vehicle fleets, drivers, customers and suppliers.
What was likely exposed
The listing refers only to “internal files exfiltrated in ransomware attack.” No inventory of specific file types or data categories has been published. Transport companies commonly store operational documents, contractual information and employee records, yet the precise contents of the exfiltrated material have not been confirmed.
Why it matters
Exposure of internal operational files can reveal details about routes, schedules and business relationships. If employee or customer records are among the files, individuals may face risks of identity misuse or targeted fraud. For the company, the incident adds operational disruption and potential regulatory scrutiny under Brazilian data-protection rules, even though the full scope of any personal-data exposure is still unknown.
What to do if you're exposed
Monitor bank and credit accounts for unusual activity and consider placing fraud alerts with relevant financial institutions. Use a unique password for each service and enable multi-factor authentication where available. Individuals can run a free exposure scan of their email address against known breach data to determine whether their information appears in public listings from this or other incidents.

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.
