Austria's Data Protection Authority has issued a decision addressing serious violations of GDPR requirements. The case centers on a processor's deletion of personal data while a data subject's right of access request remained active, representing a fundamental breach of transparency obligations under the regulation. This decision underscores the critical importance of maintaining data integrity throughout the lifecycle of regulatory requests and highlights the accountability measures that organizations must implement when handling access requests.

Rust Supply Chain Attack Linked to North Korean Hackers

A sophisticated supply chain attack has compromised the Rust ecosystem through a poisoned version of the arrayref package. Threat actors injected malicious code that established a dependency chain designed to fetch and execute a malicious payload from a remote server, demonstrating the evolving sophistication of nation-state targeting of open-source software infrastructure. The attack highlights the vulnerability of widely-used development libraries and the critical need for enhanced supply chain security practices across the software development lifecycle.
