Process Camouflage, Masquerading Process Manipulating

Masquerading is a technique used by malware to evade detection by disguising itself as a legitimate file. This is typically achieved by renaming the malicious file to match the name of a commonly found and trusted file, such as svchost.exe, and placing it in a legitimate folder.

Masquerading can occur when the name or location of an executable, …

Parent Process Detection Anti-Monitoring

Parent process is a technique used by malware to evade detection by security analysts. The parent process of a given process is the process that spawned it.

For example, most user processes on a Windows system have explorer.exe as their parent process. By checking the parent process of a given process, malware can determine whether it is being monitored …

Hook Injection Process Manipulating

Hook injection is a technique used by malware to alter the behavior of internal functions in an operating system or application. This is typically achieved by inserting malicious code into existing function calls, allowing the malware to intercept and manipulate the normal flow of execution.

In the case of Windows, the SetWindowsHookEx function can be used by programs to …

Geofencing Others

Geofencing in malware refers to a technique used by cybercriminals to restrict the distribution or activation of malicious software based on geographical location. Malware authors use geofencing to target specific regions or avoid certain areas, such as their home country, in order to evade detection, minimize the chances of being investigated, or maximize the effectiveness of their attacks.

Geofencing …

Time Bomb Sandbox Evasion Others

Some malware contains a built-in expiration date, after which the malware will no longer run or function. This can be used by attackers to limit the time during which the malware can be detected and analyzed by security researchers. In order to run and analyze the malware after its expiration date, security researchers must manually change the date on the …

NtSetDebugFilterState Anti-Debugging

The NtSetDebugFilterState and DbgSetDebugFilterState functions are used by malware to detect the presence of a kernel mode debugger. These functions allow the malware to set up a debug filter, which is a mechanism that can be used to detect and respond to the presence of a debugger.

When a kernel mode debugger is present, the debug filter will be …

Guard Pages Anti-Debugging

Memory breakpoints are a technique used by malware to detect if a debugger is present. This technique involves setting up a "guard page" in memory, which is a page of memory that is protected by the operating system and cannot be accessed by normal code. If a debugger is present, the malware can use this guard page to detect its …

SuspendThread Anti-Debugging

Suspending threads is a technique used by malware to disable user-mode debuggers and make it more difficult for security analysts to reverse engineer and analyze the code. This can be achieved by using the SuspendThread function from the kernel32.dll library or the NtSuspendThread function from the NTDLL.DLL library.

The malware can enumerate the threads of a given process, or …

Thread Execution Hijacking Process Manipulating

Thread execution hijacking is a technique used by malware to evade detection by targeting an existing thread of a process and avoiding any noisy process or thread creation operations. This technique allows the malware to run its code within the context of the targeted thread, without creating new processes or threads, which can be easily detected by security software.

…

Image File Execution Options Injection Process Manipulating

Image File Execution Options Injection, also known as IFEO Injection, is a technique used by malware to evade detection and persist on a compromised system.

The technique involves modifying the Image File Execution Options (IFEO) registry key, which is used by the Windows operating system to set debugging options for executable files. When an executable file is launched, the …
