Lake Shore Paving Listed by medusa Ransomware Group: Ransomware Claim — What’s Alleged & What To Do
Lake Shore Paving was listed by the Medusa ransomware group on May 6, 2025, after internal files were taken in a ransomware attack. If you have any connection to the company, check the group’s data dump and take steps to secure your information.
Lake Shore Paving, a small paving and excavation contractor based in Jamestown, New York, has been listed by the Medusa ransomware group as the victim of a data-exfiltration attack. Public reporting dated 6 May 2025 states that the group claims to have taken 112.30 GB of internal files. The number of people whose information may be involved remains unknown, and independent confirmation of the breach has not been published.
For a firm of this size and sector, any confirmed loss of internal records raises practical questions for employees, clients and partners about what data left the organisation and how it might be misused. The available details are limited to the group’s leak-site claim and the basic company profile released alongside it.
Inside the incident
According to the reported listing, Medusa claims to have conducted a ransomware attack against Lake Shore Paving that resulted in the exfiltration of internal files totalling 112.30 GB. The date of the intrusion itself, the method of initial access, whether systems were encrypted, and whether any ransom demand was paid or refused have not been disclosed in the public record. The sole concrete figure supplied is the claimed volume of data removed.
No statement from Lake Shore Paving confirming or denying the incident has been included in the available facts. The number of individuals potentially affected is listed as unknown. Beyond the assertion that internal files were taken, no further technical indicators, timelines or recovery status have been made public.
Who is medusa?
Medusa is a ransomware group that has operated since at least 2021 under a double-extortion model: data is stolen before systems are encrypted, and the threat of public release is used to pressure victims. The group maintains a leak site on which it posts the names of organisations it claims to have compromised, often accompanied by sample files or volume figures. Medusa has previously targeted a range of sectors, including manufacturing, professional services and local businesses, typically through phishing, exploited remote-access tools or unpatched vulnerabilities.
In this case the group’s listing of Lake Shore Paving constitutes an unverified claim. Public reporting does not state that the company has confirmed the attack or that any independent forensic verification has been released. The 112.30 GB figure and the description “internal files exfiltrated in ransomware attack” originate from the group’s own announcement.
About Lake Shore Paving
Lake Shore Paving was founded in 1998 and provides excavation, utility work, asphalt paving and concrete paving services. Its corporate office is listed at 7 Osmer Street, Jamestown, New York 14701, and the firm is reported to employ 19 people. As a regional contractor, it would typically hold project records, client contracts, employee personnel files, vendor invoices, equipment inventories and financial documents necessary to run day-to-day operations.
A breach involving a company of this profile is consequential because even modest volumes of internal data can contain personally identifiable information of staff and customers, bid details, site plans and payment records. For a small workforce and a local client base, the practical impact of any exposure is concentrated rather than diffuse.
The information in question
The only data type named in the public facts is “internal files exfiltrated in ransomware attack.” No inventory of specific categories—such as employee Social Security numbers, customer contact lists, financial statements or project blueprints—has been released. The claimed volume is 112.30 GB.
Organisations of this kind commonly store payroll and human-resources records, client correspondence, contracts, insurance documents, equipment maintenance logs and accounting files. Whether any of those categories were among the files taken remains unconfirmed. Readers should treat the precise contents as undisclosed until the company or an independent investigation provides further detail.
What's at stake
If the claimed exfiltration is accurate, employees could face risks of identity theft or targeted phishing that references real employment details. Clients and vendors might see contract terms, payment histories or site-specific information used for social-engineering attempts. For the company itself, the loss of internal files can disrupt operations, create contractual or regulatory notification duties, and erode trust among the local community it serves.
Because the number of people affected is unknown and the exact data types remain unconfirmed, the scale of individual harm cannot yet be measured. The concrete risk is that any sensitive personal or commercial information that was present in the 112.30 GB set could be sold, leaked or weaponised for fraud.
What to do if you're exposed
Anyone who has worked for, contracted with or supplied Lake Shore Paving should take a small number of practical steps while further details are awaited.
- Monitor bank, credit-card and credit-report activity for unfamiliar accounts or inquiries.
- Enable multi-factor authentication on email, financial and work-related accounts.
- Treat unsolicited messages that reference the company or recent projects with caution; verify through known contact channels.
- If you receive notice from the company, follow the specific guidance it provides regarding credit freezes or identity-protection services.
- Run a free exposure scan of your email address to check whether it has already appeared in known breach data sets.
Public information on this incident remains limited to the Medusa listing and the basic company profile. Further clarity will depend on any official statement from Lake Shore Paving or subsequent independent reporting.

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.
