Evasion using direct Syscalls Antivirus/EDR Evasion
In the Windows operating system, conventional malware frequently utilizes strategies involving the invocation of specific functions from the kernel32.dll library, such as
CreateThread. A closer inspection of the call stack reveals that the functions employed from kernel32.dll eventually trigger corresponding functions within the ntdll.dll library. This is facilitated by the ntdll.dll library, which serves …
ProcEnvInjection - Remote code injection by abusing process environment strings Process Manipulating
This method allows to inject custom code into a remote process without using
WriteProcessMemory - It will use the
lpEnvironment parameter in
CreateProcess to copy the code into the target process. This technique can be used to load a DLL into a remote process, or simply execute a block of code.
lpEnvironment parameter in
CreateProcess allows us to specify …
Process Injection: Process Doppelgänging Defense Evasion [Mitre]
Adversaries may inject malicious code into process via process doppelgänging in order to evade process-based defenses as well as possibly elevate privileges. Process doppelgänging is a method of executing arbitrary code in the address space of a separate live process.
Windows Transactional NTFS (TxF) was introduced in Vista as a method to perform safe file operations. To ensure data integrity, …
Hide Artifacts: Run Virtual Instance Defense Evasion [Mitre]
Adversaries may carry out malicious operations using a virtual instance to avoid detection. A wide variety of virtualization technologies exist that allow for the emulation of a computer or computing environment. By running malicious code inside of a virtual instance, adversaries can hide artifacts associated with their behavior from security tools that are unable to monitor activity inside the virtual …
Detecting Virtual Environment Files Sandbox Evasion
Some files are created by Virtualbox and VMware on the system.
Malware can check the different folders to find Virtualbox artifacts like VBoxMouse.sys.
Malware can check the different folders to find VMware artifacts like vmmouse.sys, vmhgfs.sys.
Some Files Example
Below is a list of files that can be detected on virtual machines:
- "C:\ProgramData\Microsoft\Windows\Start Menu\Programs\StartUp\agent.pyw",
- "C:\WINDOWS\system32\drivers\VBoxVideo.sys", …
ASProtect is a multifunctional EXE packing tool designed for software developers to protect 32-bit applications with in-built application copy protection system.
It includes software compression, provides protection methods and tools for software from unauthorized copying, analysis, disassemblers and debuggers.
ASProtect 32 also provides enhanced work with registration keys and the ability to create a single application that can change its …
Detecting Virtual Environment Process Sandbox Evasion
Process related to Virtualbox can be detected by malware by query the process list.
The VMware Tools use processes like VMwareServices.exe or VMwareTray.exe, to perform actions on the virtual environment. A malware can list the process and searches for the VMware string. Process: VMwareService.exe, VMwareTray.exe, TPAutoConnSvc.exe, VMtoolsd.exe, VMwareuser.exe.
VMProtect protects code by executing it on a virtual machine with non-standard architecture that makes it extremely difficult to analyze and crack the software. Besides that, VMProtect generates and verifies serial numbers, limits free upgrades and much more.
AxProtector encrypts the complete software you aim to protect, and shields it with a security shell, AxEngine. Best-of-breed anti-debugging and anti-disassembly methods are then injected into your software.
