TrickBot injects into the svchost.exe process. Ī Threat Group-3390 tool can spawn svchost.exe and inject the payload into that process.
ROBLOX INJECTOR 2017 JUNE CODE
Smoke Loader spawns a new copy of c:\windows\syswow64\explorer.exe and then replaces the executable code in memory with malware. RCSession can launch itself from a hollowed svchost.exe process. QakBot can use process hollowing to execute its main payload. Ī Patchwork payload uses process hollowing to hide the UAC bypass vulnerability exploitation inside svchost.exe. Some Orz versions have an embedded DLL known as MockDll that uses process hollowing and Regsvr32 to execute another payload. The NETWIRE payload has been injected into benign Microsoft executables via process hollowing. MenuPass has used process hollowing in iexplore.exe to load the RedLeaves implant.
ROBLOX INJECTOR 2017 JUNE WINDOWS
Lokibot has used process hollowing to inject itself into legitimate Windows process. Kimsuky has used a file injector DLL to spawn a benign process on the victim's system and inject the malicious payload into it via process hollowing. ISMInjector hollows out a newly created process RegASM.exe and injects its payload into the hollowed process. Gorgon Group malware can use process hollowing to inject one of its trojans into another process. ĭuqu is capable of loading executable code via process hollowing. ĭtrack has used process hollowing shellcode to target a predefined list of processes from %SYSTEM32%. ĭenis performed process hollowing through the API calls CreateRemoteThread, ResumeThread, and Wow64SetThreadContext. Ĭobalt Strike can use process hollowing for execution. Ĭlambling can execute binaries through process hollowing. īBSRAT has been seen loaded into msiexec.exe through process hollowing to hide its execution. īazar can inject into a target process including Svchost, Explorer, and cmd using process hollowing.
īandook has been launched by starting iexplore.exe and replacing it with Bandook's payload.
ROBLOX INJECTOR 2017 JUNE .EXE
exe and use process hollowing to inject it into a new process. Īzorult can decrypt the payload into memory, create a new suspended process of itself, then inject a decrypted payload to the new process and resume new process execution. Īstaroth can create a new process in a suspended state from a targeted legitimate process in order to unmap its memory and replace it with malicious code.
However, execution via process hollowing may also evade detection from security products since the execution is masked under a legitimate process.Īgent Tesla has used process hollowing to create and manipulate processes through sections of unmapped memory by reallocating that space with its malicious code. This behavior will likely not result in elevated privileges since the injected process was spawned from (and thus inherits the security context) of the injecting process. This is very similar to Thread Local Storage but creates a new process rather than targeting an existing process. At this point the process can be unmapped using APIs calls such as ZwUnmapViewOfSection or NtUnmapViewOfSection before being written to, realigned to the injected code, and resumed via VirtualAllocEx, WriteProcessMemory, SetThreadContext, then ResumeThread respectively. A victim process can be created with native Windows API calls such as CreateProcess, which includes a flag to suspend the processes primary thread.
Process hollowing is commonly performed by creating a process in a suspended state then unmapping/hollowing its memory, which can then be replaced with malicious code. Process hollowing is a method of executing arbitrary code in the address space of a separate live process. Adversaries may inject malicious code into suspended and hollowed processes in order to evade process-based defenses.
