Arbor Networks has used the IP addresses shared recently by United States authorities to analyze distributed denial-of-service (DDoS) attacks attributed to the North Korean government. The security firm believes the data may not be as useful for organizations as the U.S. hopes.

Earlier this month, the United States Computer Emergency Readiness Team (US-CERT) released a technical alert on behalf of the DHS and the FBI to warn organizations of North Korea’s Hidden Cobra activities, particularly its DDoS botnet infrastructure.
