andreyevengineering.com Listed by ransomhub Ransomware Group: Ransomware Claim — What’s Alleged & What To Do

On March 3, 2025, the ransomware group RansomHub listed andreyevengineering.com on its dark-web leak site, claiming responsibility for a ransomware attack in which internal files were exfiltrated from Andreyev Engineering, Inc. The number of people affected is unknown, and public detail on the scale, timing, and precise method of the incident remains limited.

The listing is the primary public signal of the claimed breach. For a specialized engineering firm whose work involves government agencies, developers, and property owners, any confirmed exposure of internal material could carry practical consequences for clients and partners, even while many operational facts stay undisclosed.

Breaking down the breach

Public reporting of the incident rests on RansomHub’s leak-site listing dated March 3, 2025. The group claims that internal files belonging to andreyevengineering.com were exfiltrated during a ransomware attack. No independent confirmation of the claim has been published in the available record, nor have figures for the volume of data, the number of systems involved, or the exact date of intrusion been released.

The facts do not identify whether encryption was also deployed, whether a ransom demand was issued, or whether any negotiation occurred. People affected are listed as unknown. In short, the only concrete public assertion is the group’s claim of file exfiltration; everything else about the technical sequence and impact is undisclosed at this time.

Inside ransomhub

RansomHub is a ransomware-as-a-service operation that became active in the public threat landscape in 2024, following the disruption of several larger groups. Like many contemporary ransomware crews, it typically follows a double-extortion model: data is stolen before systems are encrypted, and victims are threatened with public release if payment is not made. The group maintains a leak site where it posts victim names and, in some cases, sample files to pressure payment.

RansomHub has been observed targeting organizations across multiple sectors rather than specializing in any single industry. Affiliates are believed to handle initial access and deployment, while the core operators manage the leak site and negotiation infrastructure. Public reporting has linked the group to numerous claimed victims worldwide, though each listing remains a claim until independently verified. No statements from RansomHub beyond the listing of andreyevengineering.com are part of the present record, so no further claims specific to this victim can be attributed.

About andreyevengineering.com

Andreyev Engineering, Inc., operating as andreyevengineering.com, is a specialized engineering company headquartered in St. Petersburg, Florida. According to publicly available descriptions, the firm has more than 25 years of experience providing geotechnical engineering, environmental engineering, construction materials testing, and geophysical services. Its client base includes government agencies, developers, architects, contractors, and property owners.

Firms of this type routinely handle technical reports, site assessments, soil and materials data, environmental compliance documentation, and project correspondence. Because much of that material relates to construction, land use, and regulatory compliance, a breach can affect not only the company itself but also the third parties whose projects and properties are documented in its files. The listing therefore raises questions about the confidentiality of work product that may contain commercially or personally sensitive details.

The information in question

The available facts state only that “internal files” were claimed to have been exfiltrated. No inventory of specific data types—such as employee records, client contracts, financial documents, or technical drawings—has been published. Exact contents therefore remain unconfirmed.

Organizations performing geotechnical and environmental engineering typically store project files, laboratory test results, site photographs, correspondence with regulators and clients, and internal administrative records. Any of these categories could theoretically be present among the claimed internal files, but that possibility is inference, not established fact. Until a verified disclosure or official statement appears, the precise nature of the material remains unknown.

Why it matters

For individuals and organizations that have worked with Andreyev Engineering, the primary risk is that proprietary or personal information contained in project files could be misused, sold, or published. Even without confirmed identity-theft data such as Social Security numbers, technical documents can reveal competitive details, property conditions, or regulatory findings that parties would prefer to keep private. Clients may face secondary exposure if their own project data was stored on the firm’s systems.

For the company itself, a public ransomware listing can damage client trust, trigger contractual notification obligations, and invite regulatory scrutiny, particularly where government contracts or environmental compliance work is involved. Because the number of people affected is unknown and the data types are not itemized, the full scope of downstream risk cannot yet be measured. The absence of detail itself creates uncertainty that affected parties must navigate carefully.

What to do if you're exposed

If you have done business with Andreyev Engineering or believe your information may have been among the claimed internal files, begin by monitoring financial and credit accounts for unusual activity and consider placing a fraud alert with the major credit bureaus. Review any project-related correspondence or shared credentials for signs of compromise, and change passwords on accounts that may have been linked to the firm. Keep records of any official notifications you receive from the company or from regulators.

Because public confirmation of specific personal data is still lacking, treat the situation as a potential rather than a proven exposure. Readers can also run a free exposure scan of their email address to check whether that address has already appeared in other known breach data sets; such a scan provides an additional data point while the facts of this particular incident remain limited.
