If you are a customer of manfil.com.br, here’s what is being claimed, and what it would mean for you.

Manfil Ferro e Aço started its activities in 2000 under the name of Coferpa Ferro e Aço and with 21 years in the market, it currently offers its customers a structure with 10,000 m² of built area, 25 mts scale for 100 ton, service rebar frame with hi...

manfil.com.br Listed by lockbit3 Ransomware Group

On April 11, 2023, Brazilian steel distributor Manfil Ferro e Aço appeared on the LockBit 3.0 ransomware leak site. The listing states that internal files were exfiltrated during a ransomware attack. The company, which rebranded from Coferpa Ferro e Aço after starting operations in 2000, has not published a public breach notification detailing the volume or exact nature of the data taken.

Details from the Leak Site

The LockBit 3.0 panel entry states that Manfil Ferro e Aço suffered a ransomware intrusion and that attackers successfully removed internal files. The disclosure does not quantify the number of records affected, list specific data types such as customer personal information or financial documents, or state the ransom demand. It simply marks the company as “leaked” after the negotiation window closed. Public reporting on LockBit 3.0 indicates the group typically posts proof packages and offers to sell or freely distribute the stolen data if payment is not received.

Why This Matters for You and Your Family

When a regional supplier like Manfil Ferro e Aço is breached, anyone who has done business with the company — whether as a construction contractor, individual customer, or vendor — may have their contact details, order history, or payment records exposed. Internal files exfiltrated often contain spreadsheets that link names, addresses, phone numbers, and sometimes national identification numbers. Once that information reaches criminal marketplaces, it can be combined with other leaks to build profiles on ordinary families. The incident therefore carries direct consequences for anyone whose steel purchases or service contracts placed their information inside Manfil’s systems.

The Doxxing and Identity-Chain Risk

Stolen internal files rarely stay isolated. Attackers or subsequent buyers map email addresses and phone numbers across dozens of other breaches, creating long identity chains that lead to social-media accounts, children’s gaming profiles, and home addresses. A single leaked order record can become the anchor for doxxing campaigns or targeted phishing that reaches every member of a household. Credential leaks of this kind frequently cascade into account takeovers on gaming platforms, where children’s usernames and reused passwords become entry points for further harassment or extortion.

LockBit 3.0’s Known Track Record

Public reporting attributes the LockBit 3.0 variant to a ransomware operation that first appeared in 2019 under the original LockBit name and rebranded through successive versions. The group has claimed responsibility for attacks on hundreds of organizations worldwide, including healthcare providers, manufacturers, and logistics firms. Their standard playbook involves initial access through compromised remote desktop credentials or exploited vulnerabilities, followed by rapid exfiltration of sensitive files before encryption. They then combine data-theft extortion with ransomware deployment, publishing samples on their leak site when victims refuse to pay. The April 2023 listing of Manfil Ferro e Aço fits this pattern exactly.

What to do

  • Run a DoxxScan to map every link between your handles, emails, phone numbers, and real identity, with cleanup handled by the service.
  • Rotate any password you ever used at Manfil Ferro e Aço or related vendor portals, then enable 2FA through an authenticator app rather than SMS.
  • Enable continuous DoxxScan monitoring across 13.1B+ breach records and 100+ platforms so the next exposure surfaces in hours instead of months.
  • Cover the household with DoxxScan family protection that extends to dependents and children’s gaming accounts vulnerable to credential chaining from this claimed breach.
  • Let DoxxScan remediation specialists manage takedown requests for any exposed personal documents appearing on data-broker or extortion sites.

The Manfil Ferro e Aço breach is a reminder that even mid-sized regional suppliers sit on personal data that criminals find valuable. Staying ahead requires more than reactive checks; it demands continuous visibility and expert help when new leaks surface. DoxxScan by GalaxyWarden delivers that combination through continuous monitoring across 13.1B+ breach records and 100+ platforms, AI-powered identity-chain mapping, hands-on remediation by specialists, and full household coverage that includes children’s gaming accounts.

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.
