gamma37 5a48934822 Edit Clear Command History
I suggest a new point of view to detect that bash_history has been cleared : Instead of trying to detect all the commands that can do that, we could monitor the size of the file and log whenever it has less than 1 line.

A lot of Windows apps does not have any file characteristics. Some examples:
- Gamebar: C:\\Program Files\\WindowsApps\\Microsoft.XboxGamingOverlay_3.38.25003.0_x64__8wekyb3d8bbwe\\GameBarFT.exe
- YourPhone: C:\\Program Files\\WindowsApps\\Microsoft.YourPhone_1.20022.82.0_x64__8wekyb3d8bbwe\\YourPhoneServer/YourPhoneServer.exe

All C:\Windows\System32\OpenSSH (scp, sftp, ssh etc) does not have a description and company.

Python 2.7, 3.3 and 3.7 does not have any file characteristics.

So I don't think it is possible to whitelist all options, maybe it is worthwhile to check the \Downloads\ folder otherwise it would be better to just delete the rule. All other suspicious folders are covered by /rules/windows/process_creation/win_susp_exec_folder.yml
