Pentesters have a hard time bypassing anti-viruses nowadays Since Antiviruses are evolving as we speak. We at GBHackers decided to put some time to teach how to Bypass an Antivirus with the most common free AVs we come across in our day-to-day life.
Most novice users prefer AVAST or AVG since they are lightly weighted and don’t consume much of the computer resources so here we are using AVAST Free Anti Virus which is Running on Windows 10 Computers.
Bypassing an Antivirus Prerequisites:
- KALI,
- VEIL FRAMEWORK
- WINDOWS 10
- AVAST FREE ANTIVIRUS
Veil Framework is an old one to bypass antivirus, they generate payloads that are nearly undetectable by antiviruses. Veil can be installed by opening a terminal and run
- apt-get -y install git clone https://github.com/Veil-Framework/Veil-Evasion.git
- cd Veil-Evasion/
- cd setup
- setup.sh -c
More Information can be found on their GitHub click here

STEP 1 :
In this Kali Linux Tutorial, After installing open a terminal and navigate to the veil framework directory.
Type #python veil-evasion.py
STEP 2 :
There are few commands available, we will use the list command here to check out the payloads available by default in a veil.
STEP 3 :
Now let’s select the payload “python/shellcode_inject/arc_encrypt” numbered 37. The shellcode is encrypted by arc4 encryption and it’s decrypted using a key file in memory and then executed.
This information can be viewed by issuing the info command. use the SET command to use phyrion encrypter to yes “SET USE_PHYRION Y”
STEP 4:
Now let’s type generate the payload and use msfvenom by default and type the required handle. I have used the default reverse_tcphandler and filled out the LHOST and LPORT of kali Linux.
STEP 5:
Once the payload is successfully generated. The payload-generated location and handler file for msf will be shown. Now let’s type
#msfconsole -r /usr/share/veil-output/handlers/payload_handler.rc
STEP 6:
Now move your payload to Windows and execute We tested this on the latest free version of Avast.
Video Demonstration
The payload was executed with no pop-ups or anything from Avast and kindly watch the video we have uploaded.
