How Brand Intelligence Could Help Disrupt the Booking.com ClickFix Campaign

Summary
Microsoft reported Storm-1865 used fake Booking.com pages and ClickFix lures to deliver credential-stealing malware to hospitality staff. Cyble's sponsored walkthrough maps its brand-intelligence tools to the campaign and clarifies it did not participate in the response
Key points
- Microsoft reported Storm-1865 targeted hotel and hospitality staff across multiple regions from December 2024, with the campaign still running in February 2025.
- Lures about guest reviews, enquiries, promotions, or account verification led to fake CAPTCHA pages that told staff to paste a clipboard-copied command into Windows Run.
- The command used mshta.exe to retrieve commodity malware, including XWorm, Lumma Stealer, VenomRAT, AsyncRAT, Danabot, and NetSupport RAT.
- Microsoft said campaign payloads could steal credentials and financial data; Booking.com said its own systems were not breached, while some accommodation partners and customers were affected.
- Cyble presents domain monitoring, phishing-page detection, takedowns, and monitoring for exposed credentials as potential intervention points; it does not claim to have responded to this campaign.
- The article highlights email filtering, endpoint detection, script controls, and phishing-resistant MFA as defenses Microsoft recommended.
