대규모 유럽 전력망 장애로 인해 중요 인프라 사이버 보안이 필요합니다.

On April 28, 2025, a massive power outage struck Spain, Portugal, and parts of France, disrupting life across the Iberian Peninsula. The blackout began at 12:33 CEST and led to the sudden loss of 15 gigawatts of electricity, causing cascading failures across interconnected grids. While power was restored to most areas within 10 hours, some regions remained down for nearly 22 hours, with full recovery in Spain by 11:00 CEST on April 29. Portugal’s grid was also stabilized by early the next day using hydropower, gas turbines, and emergency imports from Morocco and France.

Even though initial logs led Red Eléctrica and REN to dismiss the likelihood of a power grid cyberattack, one must question how conclusive such findings truly are. Digital manipulation knows few limits, and skepticism remains warranted. Cybersecurity for power grids has never been more crucial.

전문가들은 이번 사건이 공격이 아니더라도 인프라에 대한 사이버 위협이 증가하고 있음을 말해줍니다. 최신 그리드는 디지털화된 시스템에 크게 의존하므로 해커에게 더 취약합니다. 단일 실패 지점; 맬웨어로 인한 것이든 조작된 데이터로 인한 것이든 전국적인 중단을 유발할 수 있습니다.

And it’s not just critical infrastructure at risk. In May 2025, Coinbase Global, the leading American cryptocurrency exchange, experienced a massive insider-assisted data breach involving over 69,000 customers. A few overseas support agents were bribed to share sensitive internal data, which included personal identifiers, ID images, and account balances. While passwords and private keys remained safe, the leaked data exposed users to serious phishing threats, impersonation scams, and even potential physical safety risks. The hackers even demanded a $20 million ransom.

이 침해는 맬웨어가 아니라 내부자에 의해 발생했습니다. 이는 신뢰할 수 있는 액세스가 어떻게 파괴적인 영향을 미칠 수 있는지를 나타냅니다. 암호화폐 거래소와 같이 규제가 심하고 보안을 인식하는 환경에서 이런 일이 발생할 수 있다면 에너지 부문은 다음과 같은 침해에 대해 진정으로 준비가 되어 있는지 물어봐야 합니다.

This isn't a distant fear. In Ukraine, on December 23, 2015, hackers used malware known as BlackEnergy 3 to take control of SCADA (Supervisory Control and Data Acquisition) systems, cutting power to over 230,000 people. That attack, attributed to the Russian group “Sandworm”, was the first confirmed cyberattack on a power grid, and it changed how the world views SCADA system security and preventing cyberattacks on national infrastructure.

이러한 공격은 일반적으로 피싱 또는 감염된 파일로 시작하여 공격자가 기업 네트워크에 액세스할 수 있도록 합니다. 거기에서 그들은 변전소를 비활성화하고, 통신을 방해하고, 복구 도구를 파괴할 수 있는 운영 기술 시스템으로 이동합니다.

Cyberattacks don’t always begin with external breaches. The Coinbase data breach is a perfect case study . The attackers didn’t need malware or network infiltration. Instead, they bribed support staff who had legitimate access to internal systems. Over months, they quietly siphoned off sensitive information that could fuel identity theft, scams, and extortion.

이와 동일한 시나리오가 중요 인프라에 적용되면 제어 시스템이 조작되거나, 사고 감지가 지연되거나, 복구가 거부될 수 있습니다. 중요한 인프라스트럭처를 보호하는 것은 단순히 방화벽과 멀웨어 탐지에 관한 것이 아니라 액세스를 제어하고, 데이터를 암호화하고, 인간의 행동을 모니터링하는 것임을 진지하게 상기시켜줍니다.

To combat such threats, encryption for businesses is crucial. It ensures that sensitive data and system commands remain secure, even if networks are compromised. Encryption blocks unauthorized access and tampering, forming a critical layer of defense. It also verifies the authenticity of control messages, preventing hackers from injecting malicious commands. Additionally, encrypted file security, logs, and backups help ensure systems can be safely restored without further compromise.

For organizations in the energy sector, investing in cybersecurity solutions for the energy sector and strong business data protection measures is no longer optional—it’s essential.
