POSCO Engineering & Construction

Profile narrative

POSCO Engineering & Construction, also known as POSCO E&C, is an engineering and construction firm headquartered in Vietnam. The company provides design, procurement, and construction services for industrial infrastructure projects, with a particular focus on piping systems and related schematics. Its work often involves collaboration with state‑owned energy firms such as PetroVietnam and Long Son Petrochemicals on large‑scale oil and gas facilities. Through these partnerships, POSCO E&C contributes to the development of processing plants, refineries, and petrochemical complexes in the region. The firm’s expertise is reflected in the technical documents it handles, including detailed engineering drawings and contract agreements.

In March 2023, POSCO Engineering & Construction was involved in a data leak that exposed infrastructure and piping schematics, employee information, business registration documents, and contract agreements shared with PetroVietnam and Long Son Petrochemicals. The breach was disclosed by the threat actor Kernelware on BreachForums, who released the data without demanding a ransom or notifying the victims beforehand. Kernelware’s history includes leaking datasets from other companies such as Acer Taiwan and Acronis, often citing boredom or minor motives before announcing a temporary hiatus due to personal commitments. Because the leaked material comprised joint project documents, it was unclear whether the compromise originated from a single system or multiple sources across the three organisations. This incident highlights the sensitivity of the engineering data that POSCO E&C manages in its sector‑focused operations.
