Over five months, four distinct malicious chains operated through the same bulletproof hosting provider, AS202412 registered to OMEGATECH LTD in Seychelles. All chains began with fake CAPTCHA pages (ClickFix technique) that instructed victims to paste commands into Windows Run dialogs. The campaigns used disposable domains with similar naming patterns, compromised legitimate websites, and varied infrastructure including cloud storage, blockchain-resolved C2 addresses, and trojanized installers. Despite different payloads and staging methods, every chain initiated contact through AS202412. The provider expanded from initial allocations to announcing twenty-four /24 prefixes during the observation period. Most browser contacts ended at the lure page without execution, but successful compromises deployed stealers and remote access tools with persistence mechanisms surviving system reboots.

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.
