# Exploitation Report

## Executive Summary

Active exploitation campaigns are targeting a diverse range of enterprise infrastructure, from network edge devices and remote management platforms to e-commerce systems and developer tools. Attackers are chaining vulnerabilities for unauthenticated remote code execution, leveraging zero-days in widely deployed software, and adopting novel evasion techniques such as invisible Unicode characters in phishing and blockchain-hosted payloads. The education sector, managed service providers, and organizations with internet-exposed administrative interfaces face immediate risk.

Multiple vendors have released emergency patches for vulnerabilities already exploited in the wild, including N-able N-central, PaperCut, Citrix NetScaler, and VMware Workstation/Fusion. However, critical gaps remain: Magento and Adobe Commerce stores face an unpatched zero-day (StyleSmuggler), ConnectWise ScreenConnect users must apply mitigations ahead of a pending patch, and a CrowdStrike Falcon zero-day exploit (FalconFlank) has been publicly released. Threat actors are also abusing legitimate features—such as session cookies and AI agents—to bypass authentication and establish covert coordination channels.
