TAMMAC Listed by blackbasta Ransomware Group: Ransomware Claim — What’s Alleged & What To Do
The TAMMAC Listed by blackbasta Ransomware Group (reported April 28, 2023) 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.
When a lender that handles home-loan applications appears on a ransomware group’s leak site, the immediate concern is practical: personal and financial details that borrowers and staff entrust to such a firm may no longer be under its sole control. On 28 April 2023, the organisation known as TAMMAC was listed by the group blackbasta, which claimed to have exfiltrated internal files in a ransomware attack. The number of people affected remains unknown, and public detail about exactly what left the network is limited.
For anyone who has applied for financing through TAMMAC, or who works with the company, the listing raises ordinary but serious questions about exposure of identity, income, and property information. What follows sets out only what has been reported, places the claim in the context of the actor involved, and outlines the concrete risks and steps that matter to affected individuals.
Breaking down the breach
According to the available record, TAMMAC was listed by the blackbasta ransomware group on 28 April 2023. The group’s claim is that internal files were exfiltrated in a ransomware attack. No confirmed figure for the number of people affected has been published, and the public summary does not describe the intrusion method, the duration of unauthorised access, or whether systems were encrypted in addition to data theft. Timing beyond the report date, the volume of material taken, and any ransom demand are undisclosed.
The listing itself is an assertion by the threat actor. Independent confirmation that the claimed files are authentic, complete, or still in the group’s possession has not been supplied in the facts available here. Organisations named on ransomware leak sites sometimes later confirm an incident; sometimes they do not. In this case, the public record stops at the group’s claim of internal-file exfiltration.
Inside blackbasta
Blackbasta is a ransomware operation that emerged in public reporting in 2022 and has since been associated with double-extortion tactics: encrypting victim systems while also copying data and threatening to publish it if payment is not made. The group typically gains initial access through compromised credentials, phishing, or exploitation of exposed remote-access services, then moves laterally, escalates privileges, and stages data for exfiltration before deploying ransomware. Its leak site has been used to name dozens of organisations across manufacturing, professional services, healthcare, and finance, often posting sample files to pressure victims.
Like other ransomware crews of its type, blackbasta’s public statements about any single victim are claims, not verified inventories. The group has a documented pattern of listing companies and, in some cases, releasing archives when negotiations stall. Nothing in the present record goes beyond the assertion that TAMMAC’s internal files were taken; no specific statements by blackbasta about the content or quantity of those files, beyond the general claim of exfiltration, are part of the facts provided.
Who is TAMMAC?
TAMMAC is a financing company focused on home loans, including purchases that involve land, use of owned land as a down payment, and loans secured only by manufactured homes. Its public description emphasises personal support through the application process and faster answers for borrowers seeking approval and financing options. The organisation lists an address at 613 Baltimore Dr Ste 1, Wilkes-Barre, Pennsylvania, and operates online at www.tammac.com.
Firms in this sector routinely collect and retain sensitive personal and financial information in order to underwrite loans, verify identity and income, and comply with lending regulations. A breach affecting such an organisation is consequential because the data it holds is directly tied to people’s creditworthiness, property ownership, and long-term financial commitments. Even when the precise scope of an incident is unconfirmed, the nature of the business means any unauthorised access carries weight for customers and employees alike.
The information in question
The facts state that internal files were exfiltrated in a ransomware attack. No further breakdown of data types—such as names, Social Security numbers, bank details, credit reports, or employee records—has been disclosed in the public summary. Exact contents therefore remain unconfirmed.
Organisations that originate and service home loans typically hold application forms, identity documents, income and employment verification, credit-related data, property and title information, and internal correspondence or underwriting notes. They may also maintain employee and contractor records. Whether any or all of those categories were among the files blackbasta claims to have taken is not established by the available record. Readers should treat specific data categories as possible rather than proven until official notification or independent verification appears.
What's at stake
For individuals, the practical risks centre on identity theft, financial fraud, and targeted phishing. If loan-application material was copied, criminals could attempt to open new credit lines, impersonate borrowers with lenders or title companies, or craft convincing messages that reference real property or loan details. Even partial files—names paired with addresses, loan amounts, or account references—can be enough to make social-engineering attempts more effective. Employees whose internal records were included could face similar exposure of payroll or personnel data.
For the organisation, the stakes include regulatory scrutiny under financial-privacy rules, potential notification duties, reputational harm among borrowers who expect confidentiality, and the operational cost of investigation and remediation. Because the scale of the incident and the precise data involved are undisclosed, the full extent of these consequences cannot yet be measured from public information alone. The absence of a confirmed headcount does not eliminate risk; it simply means affected people may not yet know they are in scope.
Were you affected?
If you have applied for a loan with TAMMAC, worked for the company, or otherwise shared personal information with it, treat the listing as a signal to increase vigilance rather than as proof that your specific records were taken. Monitor bank and credit-card statements for unfamiliar activity, consider placing a fraud alert or credit freeze with the major credit bureaus, and be cautious of unsolicited calls or emails that reference a home loan or property transaction. Official breach notifications, if required and if your data was involved, would normally come from the organisation itself; keep contact details current and watch for mail or email from TAMMAC.
You can also run a free exposure scan of your email address to check whether it has already appeared in known breach data sets. That step will not confirm or rule out involvement in this specific incident, but it can show whether your credentials or personal details have surfaced elsewhere and help you prioritise password changes and further monitoring.

Publicly posted by blackbasta — unverified claim, pending independent verification
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.
Attributions to threat groups and methods reflect public reporting and, in some cases, unverified claims made by the groups themselves; they may be incomplete or later revised.
