The company terminated the employee involved, with reports indicating an attempt by ShinyHunters to purchase network access.

    A new command-and-control platform, Matrix Push C2, is facilitating fileless, cross-platform phishing by leveraging browser push notifications, fake alerts, and redirects to distribute malicious links across various operating systems.

    Moscow-based Positive Technologies linked the China-aligned APT31 group to cyberattacks targeting entities within Russia's technology sector, indicating ongoing nation-state espionage activities.
