I discovered this wonderful project but I am not able to test its performance on my lab enviroment. The malleable c2 that I'm using is the recommended jquery-c2.4.7. The same malleable C2 works for other loaders without any issues so It might no be that. I don't know.

I'm running Cobalt Strike version 4.9.1 and I'm using the most recent version of Bokuloader. The script gave me back a "correct" output in the script console but when I try to run the .exe on the machine I got this error. AV is disabled for this test.
