GMO Group Urges Machine Shutdowns Following Cloud Breach
Japan’s GMO Internet Group instructed customers to disconnect their systems and shut down computers using its Onamae Desktop Cloud service due to an ongoing cyber incident. The breach resulted in extortion and ransomware threats, which GMO refused to pay while offering up to $1 million for information leading to the arrest of the attackers. Users of the cloud desktop service should follow company guidance to isolate their systems.

AI Tools Utilized in Automated Attacks and Vulnerability Discovery
Security researchers revealed that an offensive entity dubbed CyberStrikeAI reportedly deployed 44 AI agents to automate cyberattack operations against targets in Japan. In lab tests, Anthropic reported that an unreleased AI model successfully discovered and chained vulnerabilities into working proof-of-concept exploits across multiple operating systems. These disclosures highlight the growing reliance on artificial intelligence for both attack execution and vulnerability research.
