European Network of Transmission System Operators for Electricity (ENTSO-E) Confirms Security Incident

On Monday, the ENTSO-E confirmed that its IT network had been intruded into. Fortunately, the office network that was compromised did not have connections to any operational electric transmission system, which means the attack only affected IT systems and not the critical control systems. Lack of evidence thus far has made it difficult to determine what entity may be behind the attack, but a breach of this nature could lead to reconnaissance of supported utility operations or open the door for phishing attacks.
