LANDSTAR POWER ONTARIO INC Listed by medusa Ransomware Group: Ransomware Claim — What’s Alleged & What To Do
The LANDSTAR POWER ONTARIO INC Listed by medusa Ransomware Group (reported September 26, 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.
LANDSTAR POWER ONTARIO INC, a Canadian firm based in Orangeville, Ontario, was listed by the medusa ransomware group on or around September 26, 2023. Public reporting describes the incident as a ransomware attack in which internal files were allegedly exfiltrated. The number of people affected remains unknown, and wider technical detail has not been disclosed.
Listings of this kind signal a claim that data was taken and may be published if demands are unmet. For a company that buys and resells used batteries and scrap metal, any exposure of internal files raises practical questions for staff, partners, and counterparties even when the full scope is still unconfirmed.
Inside the incident
According to the available record, LANDSTAR POWER ONTARIO INC appeared on medusa’s listings in connection with a ransomware attack involving the exfiltration of internal files. The reported date associated with the listing is September 26, 2023. No public figure has been given for the volume of data, the number of systems involved, or the number of individuals whose information may have been touched.
Method of initial access, dwell time, encryption status of systems, and any negotiation or recovery timeline are undisclosed. The facts state only that internal files were exfiltrated in a ransomware attack and that the organisation was listed by the group. Beyond that claim and the basic company description, public detail is limited.
The group behind it: medusa
Medusa is a known ransomware operation that has appeared repeatedly in public reporting. Groups of this type commonly use double-extortion tactics: they encrypt systems where they can and separately copy data, then threaten to publish the stolen material on a leak site if payment is not made. Medusa has maintained a public-facing listing site on which it names organisations it claims to have compromised and, in some cases, releases sample files or larger archives.
Typical activity associated with such actors includes phishing or exploitation of remote-access services for entry, lateral movement inside a network, theft of files, and deployment of ransomware. Prior public cases linked to medusa have involved organisations across multiple sectors and countries. Those patterns are well documented in open sources; they do not, by themselves, prove the precise steps taken against any single named victim.
In this instance, the group’s listing of LANDSTAR POWER ONTARIO INC should be treated as a claim. The facts do not independently confirm the volume of data taken, the sensitivity of every file, or whether material was later published in full.
LANDSTAR POWER ONTARIO INC and its sector
LANDSTAR POWER ONTARIO INC is described as a Canadian company engaged in the purchase of used batteries and various scrap metal for further resale. Its office is listed at 9 Stewart Ct, Orangeville, Ontario, L9W 3Z9, Canada. Firms in scrap metal, battery recycling, and related secondary-materials trading typically manage supplier and buyer relationships, logistics, weighing and grading records, invoicing, and regulatory or environmental paperwork tied to hazardous or controlled materials such as used batteries.
A breach affecting an organisation in this sector is consequential because internal files can contain commercial terms, contact details for counterparties, shipment and inventory data, and employee or contractor records. Even when the business is not a large consumer-facing brand, disruption or exposure can affect payment flows, supplier trust, and compliance obligations around materials handling.
The information in question
The facts name the exposed material as internal files exfiltrated in a ransomware attack. No further breakdown—such as whether the files included customer lists, employee identifiers, financial statements, contracts, or operational logs—has been publicly detailed in the record provided. The number of people affected is unknown.
Organisations of this kind commonly hold, among other things, business correspondence, accounts payable and receivable data, shipping and receiving records, and personnel or contractor information. That is general sector practice, not a confirmed inventory of what was taken here. Exact contents remain unconfirmed.
What's at stake
For individuals whose details may appear in internal files, risks include unwanted contact, phishing that references real business relationships, and misuse of names, addresses, or payment-related information if such data were present. For the organisation, stakes include operational disruption, strain on partner relationships, potential regulatory notification duties under Canadian privacy rules if personal information was involved, and the longer-term cost of investigating and hardening systems.
Because the scale and precise data types are undisclosed, it is not possible to state how many people face direct exposure or which categories of harm are most likely. The prudent stance is to treat the listing as a serious claim and to watch for secondary fraud attempts that exploit knowledge of the company’s suppliers, customers, or staff.
What to do if you're exposed
If you have reason to believe your information may have been among internal files tied to LANDSTAR POWER ONTARIO INC—whether as an employee, contractor, supplier, or customer—practical first steps include:
- Monitor financial and email accounts for unexpected messages that reference the company, scrap, batteries, or invoices.
- Treat unsolicited requests for payment changes, password resets, or personal details with caution; verify through a known channel.
- Update passwords on accounts that reused credentials connected to work or supplier portals, and enable multi-factor authentication where available.
- Keep records of any suspicious contact and report clear fraud attempts to the relevant financial institution or local authorities.
- Run a free exposure scan of your email address to check whether it has already appeared in known breach datasets elsewhere.
Public detail on this incident remains limited. Further confirmation of what was taken, and whether it was published, would come only from additional verified reporting or official notices from the organisation itself.

Publicly posted by medusa — 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.
