Active Water Saci Campaign Spreading Via WhatsApp Features Multi-Vector Persistence and Sophisticated C&C

    Date: 10/28/2025

    Severity: High

    Summary

    The ongoing Water Saci campaign reveals a new attack chain leveraging an email-based C&C infrastructure with multi-vector persistence for enhanced resilience. It employs advanced evasion techniques to avoid analysis and limit activity to specific, intended targets. The campaign’s remote command-and-control system enables real-time actions such as pausing, resuming, and monitoring malware operations. Infected devices are effectively converted into a botnet, supporting coordinated attacks across multiple endpoints. Previously, Water Saci—using WhatsApp as its main infection vector and the SORVEPOTEL malware—spread malicious ZIP files to all contacts and groups for rapid propagation.
