Checking Specific Folder Name Sandbox Evasion

Specific directories, such as "C:\Cuckoo", can serve as indicators of a sandboxed or virtualized environment when present on a guest system. Consequently, a savvy piece of malware could potentially use the detection of this particular directory as a means of evading analysis. This would allow the malicious software to alter its behavior or even halt its execution altogether when it …

Checking Pipe Sandbox Evasion

Cuckoo is a malware analysis system that uses a named pipe, called \.\pipe\cuckoo, for communication between the host system (where the malware is being analyzed) and the guest system (where the malware is running).

A malware that is running on the guest system can detect the presence of a virtual environment by attempting to access the \.\pipe\cuckoo named pipe. …

SLDT, No Pill Sandbox Evasion

The No Pill technique is a method used by malware to determine whether it is running on a physical machine or a virtual machine. This technique relies on the fact that the Local Descriptor Table (LDT) is assigned to a processor, rather than to an operating system. On a physical machine, the location of the LDT will be zero, whereas …

Disabling Antivirus Antivirus/EDR Evasion

Some forms of malware are programmed to disable antivirus software and evade detection by security measures. These malicious programs can use specific commands or techniques to undermine the antivirus software's effectiveness and remain hidden from detection..

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 …

DLL Injection via CreateRemoteThread and LoadLibrary Process Manipulating

DLL Injection Via CreateRemoteThread and LoadLibrary is a technique used by malware to inject its code into a legitimate process. This technique is similar to hook injection, where the malware inserts a malicious DLL to be used by the system. It is one of the most common techniques used to inject malware into another process.

The malware writes the …

FIleless Mechanisms Process Manipulating

Fileless malware is a type of malware that is designed to reside and execute entirely in the memory of a host system, without leaving any trace on the local disk. This can make it more difficult for security tools to detect and remove the malware, as it does not leave any files on the system that can be scanned or …

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 …

Ctrl+Inject Process Manipulating

The "Control Signal Handler Callback" technique involves injecting malicious code into a process by using a callback function for control signal handlers. When a control signal, such as Ctrl+C, is received by a process, the system creates a new thread to execute a function to handle the signal. This thread is typically created by the legitimate process "csrss.exe" in the …

COM Hijacking Process Manipulating

COM hijacking is a technique used by adversaries to insert malicious code into the Windows operating system through the Microsoft Component Object Model (COM).

COM is a system that allows software components to interact with each other, and adversaries can abuse this system to execute their own code in place of legitimate software. To achieve this, they alter references …
