Summary

Show ▼
The TA558 / RevengeHotels operation expanded a summer 2025 phishing run against hotels in Brazil and Spanish-speaking markets, using invoice, reservation, and job application lures to deliver Venom RAT. The infection chain relied on JavaScript and PowerShell loaders, with some code reportedly shaped by LLM agents. The campaign matters because it targets hospitality systems that hold guest credit card data and has evolved through repeated payload swaps and lure refinements.
