28-Oct-2026 GMO Breach, Copenhagen Data Leak and AI-Powered Cyberattacks Accelerate

Hacked dAily is the first AI-driven cybersecurity podcast, created by Cytadel Cyber and published daily. Each episode delivers concise, business-focused insight for CISOs, security leaders, and decision-makers. Today’s five stories: 1. GMO has urged customers to disconnect systems and shut down PCs after a breach of its Onamae Desktop Cloud led to leaked company and customer data, with up to 26,739 servers potentially affected. MT4 and MT5 credentials and trading details may be exposed, highlighting how cloud compromises can rapidly become extortion and operational crises. 2. A cyberattack on a University of Copenhagen test environment exposed personal data belonging to about 525,000 people, including identity numbers and contact details, plus access PINs for roughly 20,000 staff and students. The university shut down systems and reset credentials, underscoring the fraud and disruption risks facing data-rich educational institutions. 3. An autonomous AI agent found four serious vulnerabilities in EPICS, software used in particle accelerator and fusion research, including a critical flaw enabling potential remote code execution. CISA is urging operators to update, highlighting how AI is accelerating the discovery of threats to industrial and research environments. 4. Researchers uncovered three AI-assisted campaigns targeting organizations in Japan, including one that used 44 agents to automate attacks against at least 19 organizations. The activity shows how AI is reducing the cost of cybercrime while accelerating reconnaissance, exploitation, data theft, and intrusion at scale. 5. Researchers identified Aokigahara, a new infostealer reportedly developed and deployed with help from AI assistants and keyrings. Its emergence reinforces the risk that faster malware development will fuel credential theft, account takeover, and wider network compromise.
