Add psexec and pskil to block application list

Hello Michel Vaillancourt,

Thank you for reaching out to the community, psexe and pskil uses  uses TCP ports 135 and 445. 
So you can simply create a drop/reject rule for the desired networks !

It is possible block psexec tool directly on sophos console?

psexec is detected as PUA since 2006.
What psexec basically does isn't really rocket science - any decent malware writer could come up with its basic and abused functionality in minutes. That a know tool is used stems from the fact that it's often used for system administration, software deployment and things like that. There's a chance that it is white-listed. But as I mentioned that it uses the ports 135 and 445 blocking those in your network can help ! 
There is no command straight forward from the console to block it ! Erik Alejos Agustí
