fileless attacks
About this tag
Fileless attacks are a growing concern in Windows security, as they bypass traditional signature-based detection by operating entirely in memory without dropping executable files. Recent discussions on WindowsForum highlight techniques like RemoteMonologue, which weaponizes Windows' Distributed Component Object Model (DCOM) to coerce NTLM authentications remotely. This fileless approach enables lateral movement and credential theft without touching LSASS or writing payloads to disk. The June 2025 Patch Tuesday addressed a critical zero-day (CVE-2025-33053) in WebDAV, underscoring the urgency of patching against such stealthy threats. For IT professionals and security teams, understanding fileless attack vectors is essential for hardening defenses and configuring EDR systems to detect anomalous DCOM and NTLM behavior.
