CONTASS Listed by 8Base Ransomware Group

On February 24, 2023, Brazilian accounting and consulting firm Contass Consultoria was listed on the leak site of the 8base ransomware group. The company, which provides services to municipal secretaries, directors, and civil servants across public administration in Minas Gerais, is claimed to have had internal files exfiltrated during a ransomware attack. The leak-site listing does not quantify how many individuals were affected nor specify the exact volume or types of records taken beyond claiming that internal files were stolen.

Reported Details from the Listing

The primary disclosure on the 8base leak site states that Contass Consultoria suffered a ransomware incident resulting in the exfiltration of internal files. No specific record count is provided, and the listing does not detail the precise data categories exposed. The company’s contact information, including its address in Montes Claros, Minas Gerais, phone number, and email, appears alongside the claim. Public reporting on 8base incidents consistently shows that once a victim is listed, the group publishes samples or full datasets if demands are not met. In this case the disclosure indicates the data was taken and is being used for extortion pressure.

Why This Matters for You and Your Family

If you or any member of your family has interacted with Contass Consultoria — whether as a municipal employee, contractor, or recipient of their consulting services — your personal information may now sit in an attacker-controlled archive. Internal files from an accounting and public-administration consulting firm often contain names, tax identifiers, addresses, financial records, and correspondence tied to government workers and their families. Even without an exact victim count, the exposure creates immediate risk because such data is frequently cross-referenced with other breaches to build complete identity profiles. For ordinary families in the Montes Claros region or anywhere public-administration data travels, this means heightened chance of targeted fraud, tax scams, or impersonation attempts in the coming months.

The Doxxing and Identity-Chain Implications

Stolen internal files rarely remain isolated. Attackers routinely combine them with credential leaks, publicly available records, and data from previous breaches to map relationships between work emails, personal accounts, and household addresses. A single exposed government-related consulting record can link your professional identity to family members, children’s school details, or even gaming usernames that reuse the same password or recovery email. This chaining turns one breach into a persistent doxxing risk where attackers can locate you across platforms, harass family members, or sell the compiled dossier on underground markets. Credential leaks like this one regularly cascade into account takeovers precisely because people reuse work-related passwords on personal services and children’s gaming accounts.

8base’s Publicly Known Track Record

Public reporting attributes the emergence of 8base to mid-2022, when the group began rapidly listing victims on its dedicated leak site. The actors have targeted organizations across multiple countries, with a focus on mid-sized firms in professional services, manufacturing, and local government support sectors. Notable prior victims include logistics companies, IT providers, and consulting practices whose client data overlapped with public-sector operations. Their typical playbook involves initial access through compromised remote desktop credentials or vulnerable web applications, followed by claimed exfiltration of internal documents before deploying ransomware. Rather than purely technical disruption, 8base emphasizes extortion: they publish sample data quickly and threaten full leaks unless payment is received. The group’s leak site remains active, and listings like Contass Consultoria follow a predictable timeline of escalating pressure.

What to do

• Run a DoxxScan to map every link between your handles, emails, phone numbers, and real identity, then use the cleanup of Warden to scrub what you can.
• Rotate any password you ever used at Contass Consultoria or related municipal systems anywhere it is reused, and switch on 2FA through an authenticator app rather than SMS.
• Enable continuous DoxxScan monitoring across 13.1B+ breach records and 100+ platforms so the next exposure that touches you or your family is caught and acted on in hours, not months.
• Cover the household with DoxxScan family coverage that extends to dependents and children’s gaming accounts, which often chain back to the same addresses or recovery emails exposed in incidents like this.
• Let remediation specialists handle takedown requests across data brokers and leak sites for you while you focus on securing day-to-day accounts.

The Contass Consultoria listing is a reminder that even regional consulting firms handling public-administration data sit in the crosshairs of efficient ransomware operations. Protecting yourself means treating every breach as a link in a larger identity chain rather than an isolated event. Start your DoxxScan trial today; its continuous monitoring, AI-powered identity-chain mapping, hands-on remediation by specialists, and full household coverage — including children’s gaming accounts — give you and your family an active defense against the next wave of leaks that will inevitably surface.
