Cmd.EXE Missing Space Characters Execution Anomaly
Detects Windows command lines that miss a space before or after the /c or /k flag when running a command using cmd.exe. This could indicate an attempt at command obfuscation or a typo. The rule specifically looks for patterns like 'cmd.exe/c', '\cmd/c', '"cmd/c', and similar for /k and /r, as well as specific commands like '/cwhoami', '/cpowershell', etc., where the space is missing. It filters out common false positives related to VS Code and specific command line endings.
