CPQD - BANCO CENTRAL OF BRASIL BLOCKHAIN. 1.8TB DATA LEAKED WITH ALL SOURCES. Listed by lv Ransomware Group: Ransomware Claim — What’s Alleged & What To Do
The CPQD - BANCO CENTRAL OF BRASIL BLOCKHAIN. 1.8TB DATA LEAKED WITH ALL SOURCES. Listed by lv Ransomware Group (reported May 2, 2022) is an unverified claim; the data involved is undisclosed belonging to roughly unknown people. If you have an account with them, your information may now be circulating on the open web and with data brokers. Here’s exactly what happened, how to check if you were affected, and what to do next.
What happened
The listing appeared on the lv ransomware group’s leak site on the reported date of May 02, 2022. The group stated that it had exfiltrated internal files during a ransomware attack and published the claim together with the headline reference to 1.8 TB of data. No further technical details about the intrusion method, the exact date of the incident, or any ransom demand have been disclosed in the available record. The number of individuals affected is listed as unknown.
Who is lv?
lv is a ransomware operation that has been publicly tracked since at least 2021. Like other groups in this category, it typically deploys encryption malware on targeted networks and then threatens to publish stolen data if a ransom is not paid. Its practice of maintaining a leak site to post victim names and sample files is well documented in open reporting on ransomware activity. Specific claims made by the group about any single victim are treated as unverified until corroborated by the affected organization or independent investigators.
About CPQD - BANCO CENTRAL OF BRASIL BLOCKHAIN. 1.8TB DATA LEAKED WITH ALL SOURCES.
CPQD is a Brazilian research and development organization that works on information and communication technologies. The name in the listing links it to blockchain-related projects associated with the Central Bank of Brazil. Entities of this type commonly hold internal project documentation, system configurations, research data, and operational records connected to financial-technology initiatives. A breach involving such an organization is consequential because the Central Bank of Brazil oversees the country’s monetary and payment systems, and any compromise of related technical environments can affect the confidentiality of internal processes even when direct customer financial records are not confirmed to be involved.
What was likely exposed
The only data type named in the listing is “internal files exfiltrated in ransomware attack.” No inventory of specific file categories, databases, or personal-information fields has been released. Organizations working on central-bank technology projects routinely maintain design documents, source code, network diagrams, access credentials, and research materials. The precise contents of the claimed 1.8 TB remain unconfirmed.
Why it matters
Exposure of internal files from a central-bank technology partner can reveal details about systems that support financial infrastructure. Even without confirmed personal data, such material may be used for further targeting or for understanding operational procedures. Individuals connected to the organization—employees, contractors, or partners—face the standard risks associated with the possible circulation of internal documents, including follow-on phishing or social-engineering attempts. The organization itself may incur costs related to investigation, remediation, and any required regulatory notifications.
If your data was in this claimed breach
Monitor financial accounts and official correspondence for unusual activity. Change passwords for any accounts that may have been associated with the organization and enable multi-factor authentication where available. Review credit reports or equivalent services for signs of misuse.

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.
