Microsoft Graph Becomes a Spy's Dead Drop as WordPress "wp2shell" Exploitation Goes Live

HOLLOWGRAPH malware exploits Microsoft 365 calendars as a covert command-and-control channel, using the Microsoft Graph API to evade detection while exfiltrating stolen data. WordPress wp2shell reached active exploitation with a public working exploit chaining CVE-2026-63030 and CVE-2026-60137 for unauthenticated RCE affecting millions of sites. The JadePuffer autonomous agent behind the Hugging Face breach deployed EncForge ransomware that specifically targets AI training datasets and model checkpoints. Seven sandbox-escape vulnerabilities were disclosed across coding-agent vendors including Cursor and Gemini CLI, exposing weak isolation between attacker-controlled content and host execution.
