Malicious Payload Evasion Techniques to Bypass Antivirus with Advanced Exploitation Frameworks

CyberWisdom Safe Harbor Commentary on Malicious Payload Evasion Techniques, with Advanced Exploitation Frameworks

A must-read story from gbhackers.com thinks things we don’t talk about but advanced threats continue to evolve, have more advanced features, bring more pain to analysis, and can even escape advanced security software such as anti-virus software.

This comparison is based on the ability of the payload to bypass the default security framework and available anti-virus systems accessible on the Windows machine, looking for a way to obtain a payload so that at the same time several security systems see how invisible.

Malicious hackers use Fileless malware to stealth, privilege escalate, collect sensitive information, and achieve persistence in the system, so malware infection can continue to play its role for a longer period of time

Metasploit

Metasploit Framework is an open source infiltration tool for creating and executing exploit code for remote target machines.

It is a subproject of the Metasploit Project. It is a PC security extension that provides data on security vulnerabilities and contributes to penetration testing and IDS signature improvements.

The Metasploit system has the world’s largest openness testing vulnerability database. Basically, Metasploit can be used to test computer framework vulnerabilities.

Meterpreter is an enhanced version of the Metasploit framework that can influence the functionality of Metasploit and further reduce the goal. Some of these capabilities include covered methods

Some of these capabilities include methods to cover your tracks, simply staying in memory, dumping the hash, entering the work frame, pivoting, and so on.

Payload operation technique
Their comparison is done by using some free tools that run on Kali Linux machines:

MSFVenom

Msfvenom is a combination of Msfpayload and Msfencode, putting these two tools into a Framework instance. Msfvenom replaces msfpayload and msfencode

In the utility provided by Metasploit, MSFvenom is the most pressing, because it is the most stressful tool for producing and encoding a standalone version of any payload in the system. The payload can be created in a variety of formats including executable files, Ruby scripts, and more importantly, thick shellcode.

The advantages of msfvenom are:
A single tool
Standardized command line options
accelerate

Veil frame

Veil-Framework is a set of red team security tools that implement a variety of attack methods focused on anti-virus evasion and evasion detection.

Anti-virus software “solutions” do not often catch the bad guys, but they often seize the written test in the task. This tool is designed to execute existing shellcodes in a way that bypasses the AV engine without having to scroll through new backdoors each time.

The Veil Framework is a collection of open source devices that can assist with data assembly and later development.

One such tool is Veil Evasion, which can be used to create payloads and avoid the use of known methods and archiving methods.

This is accomplished through various coding schemes that completely change the signature of the document, far exceeding the standard identification method.

FatRat

TheFatRat is a simple tool for generating backdoors with msfvenom, which is part of the Metasploit framework, as described earlier. The device aggregates malware with a well-known payload, and then the aggregated malware can be executed on Windows, Android, or Mac. Malware used

Malware created using this tool also reveals the ability to bypass most AV programming insurance.

Malicious payload evasion techniques

After a thorough investigation of the results obtained by iSwatlab’s security researchers, it was found that TheFatRat provided the best results, enabling Kaspersky Anti-Virus to perceive a completely unobservable payload (C# and PowerShell exe records).
