Arcandco Listed by termite Ransomware Group: Ransomware Claim — What’s Alleged & What To Do

People whose personal or financial details sit inside Arcandco’s systems now face a practical question: whether internal files taken in a claimed ransomware attack have placed them at risk of fraud, identity misuse or unwanted contact. Public detail remains limited, yet the listing of the firm by a ransomware group means those connected to its property, marine and aviation financing work have reason to treat the episode seriously.

On 19 February 2025 Arcandco was reported as listed by the termite ransomware group. The number of people affected is unknown, and the only description of the material is that internal files were allegedly exfiltrated. That is enough to warrant clear, calm attention from anyone who has dealt with the firm.

Inside the incident

According to the available record, Arcandco appeared on a termite leak-site listing dated 19 February 2025. The group claims that internal files were exfiltrated during a ransomware attack. No confirmed figure for the volume of data, no list of specific file types beyond the general label “internal files,” and no public timeline of when the intrusion began or how long it lasted have been disclosed. The method of initial access is likewise undisclosed. What is known is limited to the claim of exfiltration and the subsequent listing; independent confirmation of the full scope has not been published in the facts at hand.

Who is termite?

Termite is a ransomware operation that follows the now-common double-extortion model: encrypting systems while also copying data and threatening to publish it if a ransom is not paid. Groups of this type typically maintain dark-web leak sites where they post victim names and, in some cases, sample files to pressure payment. Public reporting on termite has described it as one of the actors that lists organisations after claiming successful intrusion and data theft. In this instance the group claims Arcandco as a victim and asserts that internal files were taken; that claim has not been independently verified in the material provided here, and no further statements attributed specifically to termite about this organisation appear in the record.

Who is Arcandco?

Arcandco, also referred to as Arc & Co., was formed in 2007 and concentrates on financing property, marine and aviation assets. Firms in this sector routinely handle sensitive commercial and personal information: loan applications, asset valuations, ownership records, banking details, insurance documents and correspondence with clients, brokers and counterparties. Because the business sits at the intersection of high-value assets and structured finance, a breach that reaches internal files can affect not only employees but also clients, guarantors and business partners whose data the firm holds in the ordinary course of lending and asset finance. The consequential nature of such an incident therefore extends beyond the company itself to the wider circle of people and organisations that rely on it for financing arrangements.

The information in question

The facts state only that internal files were exfiltrated in a ransomware attack. No further breakdown of data types—such as customer records, employee files, financial statements or contracts—has been disclosed. Organisations that finance property, marine and aviation assets typically retain identity documents, contact details, bank-account information, credit assessments, vessel or aircraft registries, property titles and related correspondence. Whether any of those categories were among the files taken remains unconfirmed. Readers should treat the exact contents as unknown until more precise disclosure appears.

What's at stake

For individuals, the practical risks include targeted phishing that references genuine financing relationships, attempts to open credit or divert payments using stolen identity data, and the longer-term exposure of personal or commercial details that are difficult to change. For the organisation, the stakes include regulatory scrutiny, potential contractual claims from clients, operational disruption and the reputational cost of a public ransomware listing. Because the number of people affected is unknown, the full scale of those risks cannot yet be measured; the absence of confirmed numbers does not reduce the need for caution among anyone who has shared information with Arcandco.

What to do if you're exposed

If you have had dealings with Arcandco—whether as a client, employee, guarantor or counterparty—consider the following concrete steps:

• Monitor bank and credit accounts for unexpected activity and enable transaction alerts where available.
• Treat unsolicited emails, calls or messages that reference property, marine or aviation financing with heightened scepticism; verify any request through a known official channel.
• Change passwords on accounts that may have been used in correspondence with the firm, and enable multi-factor authentication.
• Request a credit report or fraud alert from the relevant national agency if you believe financial identifiers could have been involved.
• Keep records of any suspicious contact so that patterns can be reported to the firm and to law-enforcement or data-protection authorities if needed.

Readers can also run a free exposure scan of their email address to check whether that address has already appeared in known breach data sets. Staying alert to unusual activity remains the most practical immediate defence while further details, if any, become public.
