Exif smuggling FileFix Detection
Detection based on: https://malwaretech.com/2025/10/exif-smuggling.html This rule detects suspicious PowerShell execution patterns that might indicate an 'Exif smuggling FileFix Technique' or similar obfuscated command execution. It specifically looks for 'conhost.exe' launching PowerShell ('powershell.exe', 'pwsh.exe', 'pwsh.dll') with an encoded command ('-e' or '-EncodedCommand'), containing more than 5 spaces, and including a UNC path. This combination of indicators suggests an attempt to execute obfuscated PowerShell code, potentially from a remote source.
