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, whether …

Homograph Attack (Punycode) Network Evasion

A homograph attack is a type of phishing attack that uses homoglyphs (characters that look similar to other characters) to create domain names or URLs that appear to be legitimate, but are actually controlled by an attacker. Homograph attacks take advantage of the fact that many languages have characters that are visually similar to characters used in other languages.

For …

FLIRT Signatures Evasion Anti-Disassembly

FLIRT Signature evasion is a technique used by malware to hide malicious code inside legitimate functions from known libraries. FLIRT (Fast Library Identification and Recognition Technology) is a database that contains signature patterns for identifying known functions from legitimate libraries.

Malware authors can abuse these signatures by modifying or adding specific bytes to the code, so that it appears to …

Process Doppelgänging Process Manipulating

This technique leverages the Transactional NTFS functionality in Windows. This functionality helps maintain data integrity during an unexpected error. For example, when an application needs to write or modify a file, if an error is triggered mid-write, the data can be corrupted. To avoid this kind of behavior, an application can open the file in a transactional mode to perform …

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 …

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 …

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 path …

DLL Proxying Process Manipulating

DLL proxying is a technique used by malware to evade detection and gain persistence on a system. It involves replacing a legitimate DLL with a malicious DLL that has the same exported functions and is named similarly to the legitimate DLL.

When a program attempts to load the legitimate DLL, it will instead load the malicious DLL, which acts as …

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 and …

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 …
