Delmar International Listed by rhysida Ransomware Group: Ransomware Claim — What’s Alleged & What To Do

In a threat landscape where ransomware groups routinely list organisations on dark-web leak sites to pressure payment, the appearance of a logistics firm can signal potential disruption to supply chains and exposure of operational data. On 29 November 2024, Delmar International was named by the rhysida ransomware group as a victim of an attack involving the exfiltration of internal files. Public detail remains limited, yet the listing itself raises clear questions for customers, partners and employees about what may have been taken and how far the incident extends.

Because the number of people affected is unknown and the precise contents of the files have not been independently confirmed, the episode underscores a familiar pattern: claims of data theft surface first, while verified scope and impact often lag. For an organisation that moves goods across borders, even limited confirmation of internal-file exposure can carry practical consequences for those whose information sits inside logistics systems.

What happened

According to the available record, Delmar International was listed by the rhysida ransomware group on 29 November 2024. The group claims that internal files were exfiltrated in a ransomware attack. No further public detail has been released on the date the intrusion began, the method of initial access, the volume of data taken, or whether systems were encrypted. The number of individuals affected is listed as unknown. Beyond the leak-site claim itself, independent verification of the breach’s full extent has not been published in the material provided.

In short, the What's Publicly Reported are narrow: a listing date, an attribution to rhysida, and a description of “internal files exfiltrated in ransomware attack.” Everything else—scale, timeline, technical vector—remains undisclosed at this stage.

Who is rhysida?

Rhysida is a ransomware operation that emerged publicly in 2023 and has since been observed conducting double-extortion attacks: encrypting systems while also stealing data and threatening to publish it if a ransom is not paid. The group maintains a leak site where it posts victim names and, in some cases, sample files or full archives. It has targeted organisations across healthcare, education, government and commercial sectors, typically using phishing, compromised credentials or unpatched vulnerabilities for initial access, followed by lateral movement and data staging before encryption.

Like other ransomware groups, rhysida’s listings are claims made by the actors themselves. They are not independent confirmations. In this instance the group asserts that Delmar International’s internal files were taken; that assertion has not been corroborated by additional public evidence in the record. The group’s established pattern is to use the threat of publication as leverage, regardless of whether every listed organisation ultimately suffers full data release.

About Delmar International

Delmar International Inc. began in 1965 as a family-run customs broker in Montreal, Canada, and has grown into a global logistics and supply-chain management company. Firms of this type handle customs clearance, freight forwarding, warehousing and end-to-end movement of goods for commercial clients. In the course of that work they routinely process shipping manifests, commercial invoices, client contact details, employee records, and operational documents that describe routes, volumes and counterparties.

A breach at such an organisation is consequential because logistics data often links multiple parties—importers, exporters, carriers and regulators—and can reveal commercial relationships or personal identifiers. Even when the exact files remain unconfirmed, the sector’s role as an intermediary means that exposure can ripple beyond the company itself to customers and partners who rely on the confidentiality of their supply-chain information.

What was likely exposed

The facts state only that “internal files” were exfiltrated. No inventory of specific data types—names, addresses, financial records, shipment details or otherwise—has been disclosed. Organisations in customs brokerage and logistics typically hold client and supplier contact information, commercial documents, employee data, and operational records necessary for cross-border movement of goods. Whether any of those categories were among the files taken in this incident is unconfirmed.

Readers should therefore treat any assumption about particular personal or commercial data as speculative until further detail is released. The sole concrete description available is the group’s claim of internal-file exfiltration; the precise contents remain unknown.

Why it matters

For individuals whose information may reside in a logistics company’s systems, the practical risks include potential misuse of contact details, commercial identifiers or other personal data if the files are published or sold. Even without confirmation of specific records, the mere possibility of exposure can prompt phishing attempts that reference the company or its clients. For Delmar International the consequences include operational disruption, potential regulatory scrutiny under privacy and customs-related rules, and the need to notify affected parties once the scope is better understood.

Supply-chain firms also sit at the intersection of many businesses; a single incident can create secondary risk for partners who shared documents or credentials. The absence of a confirmed headcount of affected people does not eliminate the need for caution; it simply means the full picture is still incomplete.

Were you affected?

If you have done business with Delmar International, worked for the company, or supplied goods or services that passed through its systems, treat the possibility of exposure seriously until more information appears. Monitor financial and email accounts for unusual activity, be sceptical of unsolicited messages that reference the firm or recent shipments, and consider placing fraud alerts with credit bureaux if you believe sensitive personal data may have been involved. Change passwords on any accounts that reused credentials associated with the company.

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 provides a practical baseline for further monitoring while official details remain limited.
