The Exchange Bank Listed by blackbasta Ransomware Group: Ransomware Claim — What’s Alleged & What To Do

On December 19, 2022, The Exchange Bank was listed by the ransomware group known as blackbasta. Public reporting states that internal files were exfiltrated in a ransomware attack. The number of people affected remains unknown, and wider technical details have not been disclosed.

For a community bank that handles personal and business accounts, any confirmed or claimed exposure of internal files raises practical concerns about customer and operational data. What is established so far is limited to the listing itself, the reported date, and the description of internal files taken during the attack.

Inside the incident

According to available public information, The Exchange Bank appeared on a blackbasta-associated listing dated December 19, 2022. The reported summary describes internal files as having been exfiltrated in a ransomware attack. No confirmed figure for individuals affected has been published, and the specific intrusion method, duration of access, encryption status of systems, or any ransom demand are not detailed in the facts provided.

Public detail is therefore narrow: a named organisation, a reported listing date, attribution to blackbasta as the claiming party, and a high-level description of data movement (internal files). Nothing further about scale, forensic findings, or containment has been supplied in the record used for this account. The group's listing should be treated as a claim unless independently confirmed by the organisation or regulators.

Who is blackbasta?

Blackbasta is a ransomware operation that became widely documented in 2022. Like other groups in the double-extortion model, it has typically combined encryption of victim systems with the theft of data, then pressured organisations by threatening to publish or auction the material on a leak site if payment was not made. Public reporting on the group has described affiliates or operators who gain initial access through common enterprise weaknesses, move laterally, and exfiltrate material before deploying ransomware.

The group has been linked in open sources to attacks across multiple sectors, including finance, manufacturing, and professional services. Its leak-site postings are claims of compromise and data theft; they are not, by themselves, independent verification of every detail asserted about a given victim. In this case, the facts state that The Exchange Bank was listed by blackbasta and that internal files were described as exfiltrated; no further specific statements by the group about this bank are included in the record.

About The Exchange Bank

The Exchange Bank is described as a community bank offering personal and business banking services, including mortgages, home loans, lines of credit, and SBA loans. Public historical notes associated with the institution trace local banking roots in Skiatook, Oklahoma, including early twentieth-century predecessors such as the Skiatook Bank (established 1905), the First Bank of Skiatook, the Oklahoma Banking Company of Skiatook (1907), and later adoption into the national banking system as the First National Bank of Skiatook, among related local developments.

Community banks of this type sit at the centre of local financial life. They routinely hold customer identity and contact information, account and loan records, credit-related documentation, and internal operational files. A ransomware incident affecting such an institution is consequential because trust, continuity of service, and the confidentiality of financial records are core to the relationship between the bank and the people and businesses it serves. That does not establish fault; it explains why even a claimed listing draws attention.

What data was at risk

The facts name the exposed material as internal files exfiltrated in a ransomware attack. No itemised inventory of fields, document types, or customer categories has been published in the provided record, and the number of people affected is unknown.

Organisations in community banking typically maintain records that can include names, addresses, account numbers, loan and mortgage files, business banking documentation, and internal correspondence or operational data. Whether any of those categories were present in the files described here is unconfirmed. Exact contents remain undisclosed beyond the general label of internal files.

The real-world impact

For individuals and businesses that bank with The Exchange Bank, the primary risks associated with exfiltrated internal files—if those files included customer-related material—are misuse of personal or financial information, targeted phishing or social-engineering attempts that reference real account or loan details, and longer-term identity or fraud exposure. Because the count of affected people and the precise data types are unknown, it is not possible to state how widely those risks apply.

For the organisation, a ransomware event that includes data theft can mean operational disruption, investigative and recovery costs, regulatory notification duties where applicable, and reputational strain with depositors and borrowers. None of these outcomes are asserted here as measured facts for this incident; they are the ordinary categories of impact that follow when internal banking files are claimed to have left the organisation’s control.

If your data was in this claimed breach

If you are a customer or counterpart of The Exchange Bank and are concerned that your information may have been involved, practical first steps include monitoring account statements and credit reports for unfamiliar activity, treating unsolicited requests for credentials or payment details with heightened caution, and following any official guidance the bank issues about the incident. Because public detail on scope remains limited, assume nothing is confirmed about your specific records until the institution or a regulator says otherwise.

• Review recent bank, loan, and credit activity for transactions or inquiries you do not recognise.
• Enable stronger authentication on financial accounts where available, and avoid reusing passwords across sites.
• Be alert to phishing that references banking, mortgages, or local branch details that could appear drawn from real files.
• Consider a fraud alert or credit freeze through the major credit bureaus if you believe sensitive identifiers may have been exposed.
• You can run a free exposure scan of your email to check whether your information has surfaced in known breach data.

Retain any notices you receive from the bank and document unusual contacts. Further clarity, if it becomes available, will come from official statements rather than from unverified third-party claims.
