high severity September 28, 2023 · 3 min read Unverified claim — what this is

palaciodosleiloes.com.br Listed by lockbit3 Ransomware Group

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

Considerada uma das maiores empresas de leiles do país, o Palcio dos Leiles norteou o seu sucesso baseado em competência, ética e profissionalismo.

— from LockBit’s own leak-site posting. This is the group’s claim, quoted verbatim; it is not GalaxyWarden’s reporting and has not been independently verified.
palaciodosleiloes.com.br Listed by lockbit3 Ransomware Group

On September 28, 2023, the Brazilian auction house Palácio dos Leilões appeared on the LockBit 3.0 ransomware leak site. The listing states that internal files were exfiltrated during a ransomware attack on the company, which describes itself as one of the largest auction firms in Brazil. The exact number of people affected remains unknown, and the leak-site posting does not detail the specific documents or data types taken.

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 582 companies.

Primary Disclosure Details

The LockBit 3.0 leak page states that Palácio dos Leilões suffered a ransomware intrusion and that attackers successfully removed internal files before encryption. No victim count, ransom amount, or file inventory is provided in the disclosure. The company’s own public description emphasizes its reputation for competence, ethics, and professionalism in the Brazilian auction market. As is common with LockBit listings, the post creates a countdown for publication of the stolen data if demands are not met.

Why This Matters for You and Your Family

When an auction company’s internal files are taken, the information often includes customer records, bidder identities, payment details, addresses, and contact information. If your family has ever participated in auctions — whether for vehicles, real estate, collectibles, or livestock — your data may now sit in an attacker’s archive. Exposure of such records can lead to targeted phishing, identity theft, or fraud attempts months or years later. Ordinary people who bid or register on these platforms rarely realize their information travels with the company’s internal systems long after the sale ends.

Doxxing and Identity-Chain Risks

Stolen internal files frequently contain more than names and emails. They can link real-world identities to usernames, phone numbers, physical addresses, and sometimes scanned documents. Attackers and downstream criminals then chain these details across other breaches to build complete profiles. A single leaked auction-house record can expose your home address, link it to email accounts, and cascade into gaming usernames or family-member profiles. This is exactly why credential leaks like this one frequently lead to account takeovers on unrelated services. Children’s gaming accounts are especially vulnerable because parents often reuse email addresses or passwords tied to family bidding profiles.

LockBit 3.0 Track Record

Public reporting attributes LockBit’s emergence to 2019, with the rebranded LockBit 3.0 appearing in early 2022. The group has hit hospitals, schools, manufacturers, and professional-services firms worldwide. Their typical playbook involves initial access through phishing or exploited remote-desktop services, followed by rapid lateral movement, data exfiltration, and then dual extortion: threatening both encryption and public release of stolen files. LockBit 3.0 operates as a ransomware-as-a-service platform, allowing affiliates to use the tool while the core team maintains the leak site and negotiates payments. The group is known for aggressive deadlines and for publishing data when victims refuse to pay.

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.
  • Enable continuous DoxxScan monitoring across 13.1B+ breach records and 100+ platforms so the next exposure surfaces in hours rather than months.
  • Rotate any password you used on palaciodosleiloes.com.br or related auction sites and enable 2FA through an authenticator app everywhere that password was reused.
  • Cover the entire household with DoxxScan family protection, which extends to dependents and children’s gaming accounts that often chain back to the same family address or email.
  • Let DoxxScan remediation specialists manage takedown requests for any exposed personal documents or broker listings that surface from this incident.

The incident underscores that auction-house customer data is now a routine target for financially motivated ransomware operators. Protecting yourself means assuming your information will appear in future leaks and maintaining constant visibility into those exposures. DoxxScan by GalaxyWarden delivers continuous monitoring across 13.1 billion+ breach records and more than 100 platforms, AI-powered identity-chain mapping, and hands-on remediation by specialists, with household coverage that includes children’s gaming accounts vulnerable to credential-stuffing attacks that often follow incidents like the Palácio dos Leilões breach.
