Did North Korean hackers launch the supply chain attack on arrayref?

CryptoRank has raised the question of whether North Korean hackers were behind a supply chain attack involving arrayref. The available report does not establish attribution, identify the attackers, or provide technical details about the alleged compromise.

Supply chain attacks target software dependencies, developer tools, vendors, or update channels rather than a final target directly. They can create broad downstream risk because a compromised component may be incorporated into multiple applications or systems.

Attribution in cyber incidents is often difficult and requires evidence such as infrastructure analysis, malware similarities, operational patterns, or intelligence assessments. North Korean state-linked hacking groups are widely associated with cyber operations and the theft of digital assets, but that broader history alone does not confirm responsibility for any specific incident.

Developers and organizations that use third-party software components generally monitor dependency alerts, review updates, and follow incident guidance when a possible compromise is identified. Further technical findings or official assessments would be needed to determine who, if anyone, was responsible for the arrayref incident.
