Since April 2026, a sophisticated multi-stage intrusion campaign has targeted hospitality and hotel organizations across Europe and Asia. The operation uses photo-themed ZIP archives containing malicious shortcut files disguised as images. When executed, these shortcuts initiate an attack chain involving obfuscated PowerShell, Node.js-based implants, and dual registry persistence mechanisms. The threat actor exploits legitimate services like Calendly and Google redirects for phishing delivery, employing authentication laundering to bypass email security controls. The campaign evolved through two waves, introducing .NET DLL compilation, Cloudflare-fronted infrastructure, and refined obfuscation techniques. Post-compromise activities include command-and-control beaconing over non-standard ports, forced shutdowns, and portable executable compilation, suggesting preparation for additional malicious operations.
