Arterium Corporation

Arterium Corporation, known also by its alias, develops tax accounting software that is widely used by Ukrainian businesses and institutions. The company’s primary product enables organisations to automate tax calculations, generate required filings, and maintain compliance with national fiscal regulations. Its software is distributed through a regular update mechanism that customers rely on to receive the latest legislative changes and functional improvements. By focusing on the tax accounting domain, Arterium serves a broad market that includes small enterprises, medium‑sized companies, and large corporations operating in Ukraine.

A distinguishing attribute of Arterium Corporation is the deep integration of its solution with Ukrainian tax authorities’ systems, allowing seamless submission of returns and real‑time validation of data. The firm has built a reputation for rapid response to legislative updates, ensuring that its software reflects new tax codes shortly after they are enacted. This responsiveness has positioned Arterium as a critical component of the country’s financial infrastructure, particularly during periods of frequent regulatory change. Moreover, the company’s update infrastructure is designed to be highly available, which underpins the trust placed in its product by a diverse user base.

Headquartered in Ukraine, Arterium Corporation operates from its main office in the country’s capital region, reflecting its national focus and operational base. The organisation’s ownership structure and any parent‑subsidiary relationships are not disclosed in the available sources, so those details remain unspecified. Despite the lack of public financial metrics, the widespread adoption of its tax accounting software indicates a significant presence within the Ukrainian market. The firm’s role in delivering essential tax technology continues to shape how Ukrainian entities manage their fiscal obligations.

On 27 June 2017, a ransomware campaign known as NotPetya exploited a compromised update mechanism in Arterium Corporation’s tax accounting software to infiltrate Ukrainian organisations. The malware, a modified variant of Petya, spread globally using the EternalBlue exploit and credential‑theft tools, permanently encrypting files while masquerading as recoverable ransomware. Security assessments concluded that the operation’s primary aim was destructive impact rather than financial gain, with attribution pointing to state‑sponsored Russian actors who had previously compromised the software’s update infrastructure. The attack caused widespread disruption across critical infrastructure, financial institutions, and government systems in Ukraine and inflicted billions of dollars in damages on multinational corporations with Ukrainian operations before containment efforts halted its spread.
