How to bypass antivirus software with Veil Framework?

In the cyber security world, the ability of attackers to bypass antivirus software is constantly evolving. At this point, Veil Framework stands out as a powerful tool for penetration testers. Running on Kali Linux and integrated with Metasploit, this framework is designed to make it difficult to detect malware. Veil, available on the GitHub repository, offers effective solutions for hiding malicious code using technologies such as Pyinstaller.

In this article, we will examine the working principles and usage of Veil Framework. We will cover the installation steps and basic usage methods. We will also learn how to test payloads created with Veil and how to evaluate their effectiveness. Finally, we will discuss the importance and future potential of this tool in the field of cyber security. This information is intended to help security experts develop their defence strategies.

What is Veil Framework and How Does It Work?

Purpose and Features of Veil Framework

Veil Framework is a powerful tool for cybersecurity professionals. This versatile framework is designed to create Metasploit payloads and circumvent antivirus solutions. Veil is open source and encrypts malicious code using various coding methods. Running on Kali Linux, this tool is used to bypass security measures on target systems during penetration tests.

Antivirus Bypass Techniques

Veil uses advanced techniques to circumvent antivirus software. It uses the Trojan horse virus to create a backdoor into the target system. This method neutralises firewalls because the target machine connects to the attacker’s computer. Veil also offers additional encoding options such as Python Encrypter, which makes payloads even more difficult to detect.

Supported Payload Types

Veil Framework offers a wide range of payloads. Payloads can be created in various programming languages such as C, C#, GO, Python, Ruby and PowerShell. This diversity allows attackers to choose the most appropriate payload according to the characteristics of the target system. This wide range of options offered by Veil provides flexibility and efficiency to penetration testers.

Veil Framework Installation and Usage

Installation Steps for Linux Systems

Veil Framework is not installed by default on Kali Linux. For installation, it is enough to open the terminal screen and use the command ‘apt-get install veil -y’. After the installation is complete, the programme is started with the ‘veil’ command. At the first run, Veil will ask to install the necessary components. At this stage, you can complete the installation by selecting ‘next’.

Basic Commands and Interface

The Veil interface has two main tools: Evasion and Ordnance. Evasion is used to create backdoor malware that can bypass antivirus software, while Ordnance provides fast shellcode generation. Select the Evasion tool with the ‘use 1’ command. The ‘list payloads’ command shows the available payloads. Payloads are classified according to programming language, type and connection method.

Payload Creation Process

The ‘use’ command is used for payload selection. For example, go/meterpreter/rev_http.py payload can be selected with ‘use 14’ command. The ‘set’ command is used to change the settings. For example, ‘set LHOST [IP adresi]”and ‘set LPORT 8080’ to set the destination and port. Finally, the payload is generated and saved with the ‘generate’ command.

Testing Payloads Created with Veil

VirusTotal and Other Online Scanners

Various online scanners can be used to evaluate the effectiveness of payloads created with Veil. VirusTotal is a popular option. However, uploading payloads to these platforms may increase the likelihood of detection. Alternative scanners can also be used. These scanners show whether the payloads have been detected by antivirus software.

Connection Test with Metasploit

Metasploit can be used to test the effectiveness of the generated payload. After the payload is sent to the target system, a security scan is initiated but is usually not detected. When the payload is executed, a connection to msfconsole is dropped and the attacker gains access to the system.

Avoidance Rates of Antivirus Software

Payloads created with Veil have a very high rate of evasion by antivirus software. For example, in scans performed on platforms such as VirusTotal and Jotti, most of the payloads cannot be detected by antivirus software. This demonstrates Veil’s effectiveness in bypassing antivirus software.

Conclusion

Veil Framework stands out as an important tool in the cyber security world. This powerful platform offers impressive capabilities to bypass antivirus software and provides valuable opportunities for penetration testers. Veil’s wide range of payloads and advanced coding techniques offer security experts an effective way to identify weak points in systems.

As a result, the use of the Veil Framework has significant implications for cyber security. This tool provides critical information to improve defence strategies and make systems more secure.
