About this tag
The windows defense tag covers discussions on defending Windows environments against evolving threats, including AI-assisted ransomware that accelerates Active Directory discovery and EDR evasion, and NTLM hash disclosure vulnerabilities like CVE-2026-20872 that enable credential leakage via File Explorer. It also addresses targeted espionage campaigns such as PassiveNeuron, which uses DLL loaders and Cobalt Strike against Windows Server hosts, and the broader context of Microsoft's record vulnerability disclosures in 2024, emphasizing the need for tightened telemetry, identity controls, and EDR tamper protection. These threads provide actionable guidance for defenders to improve detection and response in Windows-based networks.
