Root on a Fully Patched VPN, and an OAuth Grant That Outlives Revocation
Ivanti Connect Secure zero-days chained by UTA0576 achieved unauthenticated root on fully patched appliances with no implant, while a compromised ConnectWise Cloud Backup OAuth app planted service-principal backdoors in Microsoft 365 tenants that persist after consent revocation. Edge appliances including BeyondTrust Remote Support and Cisco Secure Email Gateway were exploited in a fourth consecutive week of perimeter breaches, with Qilin and Settra ransomware leveraging GlobalProtect auth bypasses. AI systems shifted from tools to operators—C2Agent malware uses LLMs over MCP for post-exploitation, CyberXero pairs Cobalt Strike with Claude Code orchestration, and attackers prompt-injected Anthropic sandboxes to steal API keys and compromise 30+ labs.
