The group behind it: sinobi
Sinobi is a ransomware operator that maintains a public leak site where it lists organizations it claims to have compromised. The group typically combines file encryption with data exfiltration and then uses the threat of disclosure to encourage payment. Its listings have included entities in multiple industries, though independent verification of each claim is often limited to the material the group chooses to publish.
About Erie Molded Plastics
Erie Molded Plastics operates a GMP facility certified to ISO 9001:2008 standards and has supplied plastic closures and caps for more than 35 years. The company serves original equipment manufacturers and distributors, offering stock products and custom production runs. Organizations in this sector routinely maintain records related to production processes, customer orders, supplier arrangements, and employee information.
What data was at risk
The only category named in the listing is internal files. No inventory of specific file types, databases, or record categories has been released. Manufacturing companies of this size commonly store customer contact details, order histories, formulation or tooling data, and personnel records, yet the exact contents removed in this case remain unconfirmed.
Why it matters
Exposure of internal files can affect relationships with customers and suppliers if proprietary or contractual information is involved. Employees may face risks if personnel records are among the material. For the organization, the incident adds operational disruption and potential regulatory or contractual obligations even when the full scope of data is still unknown.

Publicly posted by sinobi — 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.
Attributions to threat groups and methods reflect public reporting and, in some cases, unverified claims made by the groups themselves; they may be incomplete or later revised.
