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, …
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..
Process Hollowing, RunPE Process Manipulating
Process hollowing is a technique used by malware to evade detection by injecting malicious code into a legitimate process. This technique involves creating a new instance of a legitimate process and replacing its original code with the malicious payload.
The process is the following:
CreateProcess: in a suspended mode with the CreationFlag at 0x0000 0004.GetThreadContext: retrieves the …
Wiping or Encrypting Anti-Forensic
Anti-forensic techniques are methods used by malware to prevent security professionals from detecting and analyzing it. One way that malware can accomplish this is by using wiping or encryption techniques to remove its own trace from the system.
In some cases, malware may use wiping or encryption as a decoy, in order to distract security professionals and hide its true …
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.
During …
Shortcut Hiding Antivirus/EDR Evasion
Windows shortcut can be used to store code that downloads a malicious file from the internet, or that stores the malicious file directly within the shortcut itself. This can make it difficult for antivirus software to detect the malicious application, as the file is not stored in a typical location on the computer. Additionally, the use of a shortcut can …
Process Injection: ListPlanting Defense Evasion [Mitre]
Adversaries may abuse list-view controls to inject malicious code into hijacked processes in order to evade process-based defenses as well as possibly elevate privileges. ListPlanting is a method of executing arbitrary code in the address space of a separate live process. Code executed via ListPlanting may also evade detection from security products since the execution is masked under a legitimate …
Reflective Code Loading Defense Evasion [Mitre]
Adversaries may reflectively load code into a process in order to conceal the execution of malicious payloads. Reflective loading involves allocating then executing payloads directly within the memory of the process, vice creating a thread or process backed by a file path on disk. Reflectively loaded payloads may be compiled binaries, anonymous files (only present in RAM), or just snubs …
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 triggered, …
Code Transposition Anti-Disassembly
Code transposition is a technique used by malware authors to evade detection and analysis by rearranging the instructions of a piece of code without changing its behavior. This technique is used to make the code more difficult to read and understand for disassemblers and reverse engineers, as well as to hide the true intent of the code.
There are two …
