Maksymum Radio

Maksymum Radio operates under that alias and is headquartered in Ukraine. The organisation is identified by this name in publicly available sources. No further details about its founding date, ownership, or specific activities are provided in the source material. This limited information forms the basis for the known facts about the entity.

On June 27, 2017, Maksymum Radio was affected by the NotPetya cyberattack that targeted Ukrainian organisations through a compromised update mechanism of widely used tax accounting software. The attack began when a malicious update was distributed via the software's legitimate supply chain. Once executed, the malware encrypted the master boot record and rendered systems inoperable. This initial vector allowed the threat to gain a foothold within the organisation's network.

From that foothold, NotPetya propagated using the EternalBlue exploit and harvested credentials to move laterally across connected systems. The malware spread beyond Ukraine, affecting financial institutions, government ministries, critical infrastructure, and media outlets worldwide. Although it presented itself as ransomware, its primary purpose was destructive, causing permanent data loss on many machines. Estimated global damages from the incident exceed ten billion dollars, with considerable collateral damage to multinational corporations.

Attribution analyses conducted by multiple governments and security firms linked the operation to Russian military actors. Ukrainian authorities managed to halt the active spread of the malware within a few days, but warned of residual backdoors remaining in the compromised software supply chain. These lingering vulnerabilities continued to pose risks for organisations that had not fully patched or restored their systems. The incident remains a notable case study in supply-chain attacks and geopolitical cyber conflict.
