Many thanks for reporting this issue

If possible could you post a link to the malware sample, zipped with password ‘infected’

Also could you please post your active process list or Killswitch display when the malware is running.

Best wishes


Done !


Sorry to trouble you further but if possible please record the Killswitch processes when the malware is running. Please also open Killswitch in advance so at the ratings are showing - some are currently showing ‘analysing’.

Kind regards


Thanks for bringing my attention, the problem occurred because of my use killswitch private CCE
I modified the first post

Same here I am afraid.

Could you please show the RAT malware running in a Killswitch display

Preferably a screenshot so I can see the process tree?

Many thanks

Thanks SD very much. OK so it’s a straightforward single process sandboxed as FV

Could I just confirm whether the malware window is in foreground or background when able to:

  1. capture screenshots
  2. Capture keystrokes
  3. Capture clicks

(Is it the on-top Window).

If it is in foreground then I think this is by design, unfortunately.


It is already there is only one process “counter strike.exe”


Sorry I think we are having language difficulties

I will try with simpler sentences.

When it captures screenshots is it the foreground window?

When it keylogs is it the foreground window?

Kind regards


I am sorry for my poor English, malware keep the background only, and does not show any interface, only in the one case : if haker wants to open chat with the victim

Note: This is a malware type of njrat
Please see this topic :

OK SD, forwarding. Many thanks for the great bug report.


JUst to double check. Does this exploit function in the release version too? 8.0 4337

The answer is yes, in all versions of CIS 8 final and beta

Thanks SD, I have raised its priority accordingly.
