Municipal taxation Secretariat Access - Brazil Goverment Listed by Babuk2 Ransomware Group

On March 19, 2025, the Babuk2 ransomware group listed the Municipal Taxation Secretariat of a Brazilian government entity on its leak site, claiming to have exfiltrated internal files during a ransomware attack.

You can’t unleak data. You can take away what it’s worth.

A leaked record is where it starts, not where it ends. What turns it into your front door is the look-up sites publishing your address beside your name — and those are what an AI reads when somebody asks about you. The free scan shows you both. We write to 580 companies.

What Public Reporting Shows

Public reporting indicates the incident targeted the Municipal Taxation Secretariat, part of Brazil’s government infrastructure responsible for local tax collection and citizen financial records. The attackers posted evidence on their dark web leak site, accessible via an onion address tracked by ransomware.live. Available reporting describes the exposed material as internal files, though the exact volume and full list of data types remain unconfirmed in initial disclosures. No precise victim count has been released, leaving an unknown number of Brazilian taxpayers and municipal employees potentially affected. The group set a deadline typical of its operations, after which it threatens to publish or sell the stolen data.

Why This Matters for You and Your Family

When government tax offices are breached, the information at risk often includes names, addresses, tax identification numbers, income details, and banking information tied to ordinary citizens. These records can be used for identity theft, fraudulent tax filings, or targeted scams that hit family finances directly. If your municipality or region interacts with this secretariat, your household data may now sit in attackers’ hands. Children’s records linked to family tax filings can also surface, increasing long-term risks of financial fraud or harassment that follow families for years.

The Doxxing and Identity-Chain Implications

Tax records frequently contain the exact links attackers need to build full identity chains: home addresses, phone numbers, email accounts, and government ID numbers. Once these appear on criminal forums, they enable cascading attacks. A single leaked email can unlock linked social media, shopping accounts, and gaming profiles. Credential leaks like this one routinely cascade into account takeovers and doxxing chains, especially when gaming accounts belonging to children share the same family email or address. Public reporting attributes similar incidents to rapid escalation once initial government data reaches underground markets.

Unverified claim — what this report is

This page documents a public listing on a ransomware/extortion group’s leak site, tracked via public threat-intelligence sources. A listing is the attacker’s claim. GalaxyWarden aggregates and reports such claims; we have not independently verified that a breach occurred, what data (if any) was taken, or the accuracy of anything the group asserts, and the named organisation has not necessarily confirmed the incident. Sections above describe what the listing shows and the group’s documented history — not verified findings about the named organisation. If you represent this organisation and believe anything here is inaccurate, tell us and we’ll review it promptly.

GalaxyWarden is a breach-monitoring service and news aggregator. We do not exfiltrate, host, purchase, or redistribute stolen data. Breach information is compiled from publicly accessible sources and threat-intelligence platforms, and is reported as claims attributed to their source.
