Gophish MODs
Modify Gophish to Bypass Detection
Was recently working on a Phishing Engagement. I always modified Gophish manually to evade detection. This time I thought of the principle, "Don't Do Anything Twice: When it Makes Sense to Automate" . Before I started manually typing scripts I searched github.com for gold (basically if someone else tried to do it). I found this amazing docker-compose file which does all of the things which I wanted to do.
So I'm stealing work? Probably yeah !! I dont want docker so I'll probably just extract useful content from the docker-container file and run it on my gophish server πŸ€·β€β™‚οΈ
