Description

Detects suspicious usage of the cmd.exe 'for /f' loop combined with the 'tokens=' parameter and a recursive directory listing. This pattern may indicate an attempt to discover and execute system binaries dynamically, for example powershell, a technique sometimes used by attackers to evade detection. This behavior has been observed in various malicious lnk files.
