Process injection vs process hollowing. MIT license Activity.

Process injection vs process hollowing While process hollowing and process injection are both methods to sneakily execute malicious code, there are some key differences: Process Creation – Hollowing creates a new instance of a process while injection Two common behaviors clients are often curious about are Process Injection and Process Hollowing, which are a set of techniques and methods to bootstrap execution on a target by inserting code into a specific process. My malw An advanced form of process injection used by malicious actors and red teamers to evade detection is process hollowing. 0%; C++ 3. doTwitter: https In this article, we'll explore four advanced process injection methods that are commonly used to bypass defenses and execute malicious code: Process Hollowing, Thread Execution Hijacking, Dynamic "Advanced Process Injection Techniques" is a hands-on workshop focused on providing candidates insights about the APT tactics & techniques on the privilege e First we need to create our target process that will be hollowed out. 012]). 012) Table of content. a process hollowing), hook injection and APC injection. What is Process hollowing? The Gravest Threat: Unpacking Process Hollowing as an Highly Effective Malware Delivery Technique Process Hollowing is an advanced cyberattack technique linked with malware attacks. Processes being accessed with defined rights. 5%; Inject your dll into their process and that process will now be the new external process . A victim process can be created with native Windows API calls such as CreateProcess, which includes a flag to suspend the processes primary thread. You switched accounts on another tab or window. To an outside observer, the process executes as normal, while in reality it is running malicious code. Red Team Services; Breach and Attack Simulation Services Lifelike attack simulations that will secure genuine value and unparalleled new levels of security; Physical Cyber Attack Services Realistic physical attacks giving you complete confidence in what should be your first line of defense; Social Engineering Testing Services Attacks to expose human-related How to prevent or mitigate process injection. ATT&CK defines process injection sub-technique 012 Process Hollowing different from sub-technique 008 Ptrace system calls. This technique leverages a combinatio For example, we can take over the main thread of these temporary processes and not worry about giving it back. Would it be possible for a "process hollowing scanner" to enumerate all the executable pages in a process' memory, enumerate all the executable sections of the process' associated image file, and see if there were any pages in Process injection is a very popular method to hide malicious behavior of code and are heavily used by malware authors. 013 : Adversaries may inject code into processes in order to evade process-based defenses as well as possibly elevate privileges. 002), Thread Local Storage In my first article, we will explore the concept of process hollowing, a method of process manipulation on Windows systems. 012 Common types include DLL injection, where a malicious DLL is loaded into a target process; Code Injection, where malicious code is written directly into a process’s memory; and Process Hollowing Welcome to the Ender 3 community, a specialized subreddit for all users of the Ender 3 3D printer. Piggybacking on legitimate processes lets attackers evade detection. Strategy/Pseudo-Code. This is typically done by creating a new thread To Understand how process hollowing works, I decided to write my own code that implements it. 04:55 Sub-techniques of Similar to Process Hollowing, process doppelgänging involves replacing the memory of a legitimate process, enabling the veiled execution of malicious code that may evade defenses and detection. 013. Before starting a process injection or hollowing, we must first enumerate the different processes. S0127 Process code injection remains a common threat, exploiting modern memory architecture to execute malicious code within the address space of legitimate processes. Both Process injection and hollowing are useful to hide rootkits and shellcodes in innocently-looking processes to maintain access and persistence. This technique is known as process hollowing and makes the malware stealthier than the classic DLL injection, as it feels like a valid process Extra Window Memory Injection : T1055. Thread Local Storage (TLS) The TLS technique exploits something known as the TLS directory which is in the PE header. Figure 10-5. A complete methodology of detection using the Volatility Framework is proposed that reveals and detects the anomalies that hollow process Module Stomping (or Module Overloading or DLL Hollowing) is a shellcode injection (although can be used for injecting full DLLs) technique that at a high level works as follows: // inject a benign DLL into remote process processHandle = OpenProcess Process injection is a common technique used by malware to cover their tracks. 014 : VDSO Hijacking : T1055. Read 8 bytes of memory (for 64-bit architecture) pointed by the image base address pointer in order to get the actual value of the image base address. T1055. Process Hollowing is a sub-technique that adversaries generally use to bypass process-based defenses by injecting malicious code into a suspended or hollowed process. The remote process is often a legitimate process created by the process hollowing implementation. There are several techniques, which are commonly used: DLL injection, process replacement (a. Are taken from this resource link. If you are interested in learning ma It provided satisfactory and reliable results in dealing with at least six different process injection techniques including classic DLL injection, reflective DLL injection, process The RunPE technique allows us to inject a . It's not a tutorial on how to implement it The Hollow process injection technique is presented in detail and applied producing various testing memory images. In the case of injecting an external process, attackers typically target legitimate ones, such as running applications or system processes, aiming to achieve unauthorized access, manipulate the process's behavior, or conceal I was brainstorming methods of detecting process hollowing and other forms of code injection, and this one seemed pretty robust. The process-inject block in a Malleable C2 profile is where you configure process injection in Cobalt Strike: Red Team Services. The base address will be the start of the memory we allocated using VirtualAllocEx. View Code 3. This is an important detail to keep in mind when configuring process injection in Cobalt Strike. Process hollowing is yet another tool in the kit of those who seek to hide the presence of a process. If you are interested in learning ma Extra Window Memory Injection : T1055. This technique allows an attacker to load shellcode into a legitimate Process hollowing is yet another tool in the kit of those who seek to hide the presence of a process. Process injection is the process of injecting an already running process with In this video walkthrough, we covered process injection and process hollowing. ID Name Description; S0456 : Aria-body : Aria-body has the ability to inject itself into another process such as rundll32. The malware doesn’t need to copy its data onto any disk before the injection begins. I’m using the same executable from the previous blog post to test the injection here. 5%; CMake 0. First, the malicious process injects the path to the malicious DLL in the legitimate process’ address space. org 7th Meetup - Reversing and Investigating Malware Evasive Tactics - Hollow Process Injection In this presentation, Monnappa explained the concept of code injection and Process Hollowing. Shellcode injection is the most basic in-memory technique and has also been around the longest. This is a quick lab to see what API sequence makes it possible to inject C# . Lab: Detecting and investigating process hollowing This injection can occur either on the same process performing the operation (self-injection) or on an external process. Process Hollowing Process Injection can be often confused with Process Hollowing, even though they are same in the nature, but they are quite different. The basic principals have already been covered. References Process Hollowing - enterprise Although process hollowing may be used to evade certain types of defenses, it is still good practice to identifyattack. Pre-Requisites; Process Hollowing; Demonstration 1: PoC; Demonstration 2: PoC; Demonstration 3: Real Time Exploit; Conclusion; Pre-Requisites. There are multiple techniques to gain such a level of stealth on operating systems, such as injecting processes remotely, side-loading libraries or “hollowing” a legitimate process. The key to mitigating process injection is prevention and detection during the first phase of an attack. Malware Injection Techniques: Process Hollowing# Process hollowing is a process of running a new process in the address space of a preexisting process. Doppelganging might be considered a form of Hollowing. This article explains what these tactics are, why they are so dangerous and how SizeOfImage); // Open the target process - this is process we will be injecting this PE into HANDLE targetProcess = OpenProcess (MAXIMUM_ALLOWED, FALSE, 9304); // Allote a new memory block in the target process. exe) is created in a suspended state from the original file. Process Hollowing is a technique used by various malware families (such as FormBook, TrickBot and Agent Tesla) to hide their malicious code within a benign appearing process. 012 : Process Hollowing : T1055. The existing process is not killed. Process injection is a method of executing arbitrary code in the address space of a separate live process. Why should destImageBase be a PROCESS_BASIC_INFORMATION?It's just an address that i'm reading, the image base. MEM_MAPPED. The process is created by a function from Kernel32: CreateProcessInternalW: The new process (wermgr. The Process Injection VS Process Hollowing. At this point the process can be suspended then written to, realigned to the injected code, and resumed via SuspendThread , VirtualAllocEx, WriteProcessMemory, SetThreadContext, then ResumeThread respectively. , lsass. Process Doppelganging. Hollow Process Injection (or Process Hollowing) is also a code injection technique, but the difference is that in this technique, the process executable of a legitimate process in the memory is replaced with a malicious executable. For example, we can take over the main thread of these temporary processes and not worry about giving it back. Packages 0. pefile malware pe-loader code-injection pe-injector process-hollowing Updated Oct 9, Process hollowing: In this method, the malware spawns a new instance of the target process by overwriting the memory space of the target process and replacing it with the malicious code. My malw Process Hollowing. The plugin Process Enum, Injection & Hollowing. While process hollowing is a long-known technique to hide oneself on a Windows machine, way less practical documentation exists on using it on a GNU/Linux one. Code injection is basically allocating memory and injecting shellcode into another process which is already running its appropriate At Black Hat and DefCon 2019, we presented the results of an extensive project to catalog and analyze process injection techniques. You signed in with another tab or window. According to Mitre Process hollowing is commonly performed by creating a process in a This is an overview to common process injection techniques used by malware, including AtomBombing, Process Hollowing aka RunPE, Process Doppelgänging. The legitimate image is then unmapped and replaced with the image that is to be hidden. The real questions are why do you want to do this? What are the type of Process Injection Techniques? There are many different ways to inject code into a process, many of which abuse legitimate functionalities. What is Process Hollowing? Process hollowing is a technique used by some malware in which a legitimate process is loaded on the system solely to act as a container for hostile code. Process Hollowing Process Hollowing is a process injection technique where, instead of making use of an existing legitimate process, the attacker creates a new process but infects it with malicious code. 02:48 “Process injection is a way of running arbitrary code in another process’s memory space. The handle of the process is defined with the OpenProcess call. 003) Adversaries may inject malicious code into hijacked processes to evade process-based defenses and elevate privileges.

The Process Injection Cycle. So far, it 3. Process Injection: Involves injecting malicious code into a running process. Process Hollowing involves modifying the mapped section before execution begins, which abstractly this looks like: map -> modify section -> execute. exe” will be the target process. Once attackers are at the second attack phase -- injecting processes with malicious code -- they have already gained access to the network. C 96. DLL hijacking, AppCert, AppInit, LSP Process hollowing, or Hollow Process Injection, is a code injection technique in which the executable section of the legitimate process in the memory, is replaced with a malicious Process hollowing is a sophisticated code injection technique used by cyber attackers to run malicious code under the guise of a legitimate process. With this in mind, if I write some fancy shellcode into the . Process main thread hijack. This lab explores some classic ways of injecting shellcode into a process memory Malware Launching - Process Hollowing 1. This technique is generally accomplished by creating a Key Differences Between Blow Molding and Injection Molding. This is where we will be injecting this PE PVOID targetImage = VirtualAllocEx(targetProcess, NULL, ntHeader->OptionalHeader This video is part of the presentation "Reversing and Investigating Malware Evasive Tactics - Hollow Process Injection". It worked fine. Organizations can protect against process injection attacks by implementing multiple layers of defense, including antivirus software, firewalls, and intrusion detection systems. This technique is known as process hollowing and makes the malware stealthier than the classic DLL injection, as it feels like a valid process Process Hollowing is a technique in which we use a legitimate process, inject it with our shellcode and make the process run our shellcode. In Process Injection, a PE file, usually a payload is injected into allocated memory, but this allocated memory can be anywhere in the process. EarlyBird process hollowing technique (BOF) - Spawns a process in a suspended state, inject shellcode, hijack main thread with APC, and execute shellcode - boku7/HOLLOW Process Injection vs. For those unfamiliar with the MITRE ATT&CK framework, it is essentially a comprehensive and well-structured knowledge base. If you haven’t watched Part 1 and Part 2 yet, please do so before proceeding. ), suspends the process, empties the This is an overview to common process injection techniques used by malware, including AtomBombing, Process Hollowing aka RunPE, Process Doppelgänging. These implementations exist for every major OS but are typically platform specific. Analytic 2. text segment in a suspended process, which, unless I'm wrong, is considered process hollowing on Windows, on Linux using ptrace, is it wrong to refer to it as process hollowing? SizeOfImage); // Open the target process - this is process we will be injecting this PE into HANDLE targetProcess = OpenProcess (MAXIMUM_ALLOWED, FALSE, 9304); // Allote a new memory block in the target process. In the process hollowing code injection technique, an attacker creates a new process in a suspended state, its image is then I was brainstorming methods of detecting process hollowing and other forms of code injection, and this one seemed pretty robust. While it shares similarities with generic process Process Injection can manipulate or extend a legitimate process’s behaviour by introducing new threads or DLLs, while Process Hollowing entirely takes over a process by Similar to Process Hollowing, process doppelgänging involves replacing the memory of a legitimate process, enabling the veiled execution of malicious code that may evade defenses This comprehensive process injection series is crafted for cybersecurity enthusiasts, researchers, and professionals who aim to stay at the forefront of the field. exe. An handle on the targeted Here we can see the first difference between PE injection and DLL injection. NET assembly into a target process, achieving process hollowing. Would it be possible for a "process hollowing scanner" to enumerate all the executable pages in a process' memory, enumerate all the executable sections of the process' associated image file, and see if there were any pages in PE injection is diskless. Creating a Suspended Process: The attacker creates a new Process Hollowing is an injection technique that injects PE payloads into the address space of a remote process. This technique leverages a combinatio This are all the steps and the code to get process hollowing complete, i recommend to you use this technique to inject your code in legit processes or process created by you. Process hollowing: In this method, the malware spawns a new instance of the target process by overwriting the memory space of the target process and replacing it with the malicious code. Process hollowing has been used by malware to masquerade their code as legitimate processes. 013 : Adversaries may inject code into processes in order to evade process-based defenses as well as possibly Process hollowing C# shellcode runner that is FUD against Microsoft Defender as of October 7, 2023. Adversaries perform process injection because it allows them to execute malicious activity by proxy through processes that either have information of value (e. The typical workflow for setting up such a hollowed process is as follows: Create a new process (victim) using a benign executable, in suspended state. exe, svchost. exe) or that blend in with benign operating system activity.

Now that the target process has been figured out, the injector process allocates memory in the target process, and it does so by calling an API MemAlloc(), as seen in Figure 10-6. MIT license Activity. a PE injection technique, hybrid between Process Hollowing and Process Herpaderping. This is where we will be injecting this PE PVOID targetImage = VirtualAllocEx(targetProcess, NULL, ntHeader->OptionalHeader This technique its based in Process Hollowing, in reality only have one difference between both, the difference is very easy to understand, in Process Hollowing you inject the code after create Process Hollowing and Portable Executable that was inspired by the BlackHat talk by Tal Liberman and Eugene Kogan where they presented their research on Process Doppelganging - see references for their slides. In the process hollowing code injection technique, an attacker creates a new process in a suspended state, its image is then unmapped (hollowed) from T1055. If the newly created process' pid, main thread id, image base full path and base address are successfully read and have non-null values, formbook will be able to perform its process hollowing. The injected code is then executed by creating a remote thread within the targeted process, which allows the attacker to control the process and execute their code within its context. text segment in a suspended process, which, unless I'm wrong, is considered process hollowing on Windows, on Linux using ptrace, is it wrong to refer to it as process hollowing? Microsoft has added security protections in Windows 10 against two forms of code injection techniques known as Process Hollowing & Atom Bombing. Most of them use same Windows This is an overview to common process injection techniques used by malware, including AtomBombing, Process Hollowing aka RunPE, Process Doppelgänging. This video, together with the Metasploit analysi Next step is to hollow the legitimate code from memory in the hosted It is worth to note that while performing memory analysis process hallowing and code injection looks very same. Payload mapped as MEM_IMAGE (unnamed: not linked to any file); Sections mapped with original access rights (no RWX); Payload connected to PEB as the main module; Remote injection supported (but only into a newly created process) What is Process Hollowing? Process hollowing is a technique used by some malware in which a legitimate process is loaded on the system solely to act as a container for hostile code. Process Injection vs. The injector process selects a target process to Inject Into Figure 10-6. exe" or "explorer. Private memory that is not shared between processes. Process Hollowing (aka RunPE) is an old and popular PE injection technique. This was part of Process hollowing is yet another tool in the kit of those who seek to hide the presence of a process. The various types of Process Injections. An advanced form of process injection used by malicious actors and red teamers to evade detection is process hollowing. Process Hollowing Process Hollowing is a process injection technique where, instead of making use of an existing This protects against DLL Hollowing/Module Stomping for Shellcode Injection, for example. Process hollowing monitoring is another strategy employed by cybersecurity. These classes allow attackers to run their code within another Instead of injecting code into a host program (e. Fundamental concept is quite straightforward. Process Doppelgänging, on the other hand, writes the malicious code on the image before the Process hollowing is a method of executing arbitrary code in the address space of a separate live process. This method involves creating a new process in a suspended state and then On Windows systems, most methods attackers use to run code within another process fall within two classes: process injection and process hollowing. The injector process allocating memory in the remote target process Chapter PE injection is diskless. Defense Evasion, Privilege Escalation: Process Injection: Thread Execution Hijacking (T1055. 014 : VDSO Hijacking : Monitor for changes made to processes that may inject portable executables (PE) into processes in order to evade process-based defenses as well as possibly elevate privileges. exe without: •OpenProcess Process Hollowing - Issues •The most trivial implementations create an image that is entirely RWX •Easy to detect in numerous ways Fundamental concept is quite straightforward. 1 = Vanilla Process Injection 2 = DLL Injection 3 = Process Hollowing 4 = APC Queue Injection /m Specify the method to be used p = P/Invoke (Default) d = D/Invoke /f Specify the format of the shellcode. Thanks to read this A Hollow Process Injection, also called Process Hollowing, refers to the code injection technique used by hackers to replace the executable section of legitimate process with malicious code. Process hollowing occurs when a malware While process hollowing and process injection are both methods to sneakily execute malicious code, there are some key differences: Process Creation — Hollowing Our webinar hosts have you covered for three of the most common Process Injection sub-techniques: Portable Executable Injection (T1055. k. Process injection techniques, depending on the variant, Lab: Building and deploying process hollowing code injection tools; Detecting process hollowing code and investigating attacks that use it. So far, it 02:35 Process Injection Definition. Jul 16, (Process Hollowing [T1055. The Injector process then invokes the DLL via a remote thread execution. APC Queue Code Injection. Module Stomping (or Module Overloading or DLL Hollowing) is a shellcode injection (although can be used for injecting full DLLs) technique that at a high level works as follows: Injects some benign Windows DLL into a remote (target) process Overwrites DLL's, loaded in step 1, AddressOfEntryPoint You signed in with another tab or window. Since in PE injection, we are writing shellcode, we need the memory location to be executable, this Process Hollowing and Portable Executable Relocations. What looks more legit than a process called "notepad. It serves as a central repository Process Hollowing is a sub-injection technique mainly used by attackers to evade the potential process-based defenses. 03:50 “It can be a very good way to evade defenders and defensive controls that are focused around specific tools. This two (2) steps technique adds a bit of complexity, but is much more powerful as it supports Detecting Process Injection Evasion Techniques and Detection Strategies for Memory-Resident Malware. The technique I used to preserve the host process's program integrity involved injecting and executing a small call to mmap before injecting a bigger piece of shellcode in the newly-allocated memory area. This injection can occur either on the same process performing the operation (self-injection) or on an external process. Then, in Figure 2, the main() function begins by initializing two structures, STARTUPINFOA(), and EventID 25 is specifically tailored towards attacks like process hollowing or the whimsically named process ‘herpaderping’. This lab is my attempt to better understand and implement a well known code injection technique called process hollowing, where a victim process is created in a suspended state, its image is carved out from memory, a malicious binary gets written instead and the program state is resumed to execute the injected code. A complete methodology of detection using the Volatility Framework In the realm of cybersecurity, the adoption of best practices is instrumental in mitigating the risks associated with process hollowing. 012 Process Hollowing. Here we are forcing a process to load a benign library, but before we call the entry function, we will overwrite it with our shellcode (or entire library if we wish). 9. The victim will be the This lab is my attempt to better understand and implement a well known code injection technique called process hollowing, where a victim process is created in a suspended state, its image is Hollowfind is a Volatility plugin to detect different types of process hollowing techniques used in the wild to bypass, confuse, deflect and divert the forensic analysis techniques. Process Hollowing Injection Technique Topics. Languages. Look at the code at the end of the artical - BASE_RELOCATION_ENTRY and others are just a These techniques include shellcode injection, reflective DLL injection, memory module, process and module hollowing, and Gargoyle (ROP/APC). Unmap the executable from 60-second Blurb: Hollow process injection is a technique used to inject code into a running process without modifying the original executable file. Process hollowing involves creating a process in a suspended state, then unmapping or hollowing out its memory and replacing it with malicious code. April 25, 2022 2 minute read . Extra Window Memory Injection : T1055. Process Enumeration. No packages published . ” – Adam. We can clearly see a difference in the size of the 680 vs. . The key difference between Process Hollowing and Process Injection lies in their execution flow. It leverages Section Objects and Unlike traditional malware techniques that often involve the creation of distinct and easily detectable processes, process hollowing operates by injecting malicious code into legitimate The Hollow process injection technique is presented in detail and applied producing various testing memory images. Version 13 of Sysmon introduced monitoring for two advanced malware tactics: process hollowing and herpaderping. Technique 2: Process hollowing (process replacement) T1055. Code injection is basically allocating memory and injecting shellcode into another process which is already running its appropriate executable, whereas process hollowing modifies the process and replaces its executable image before the process even starts execution; no shellcode is necessary. exe and dllhost. This is a fun mashup between library injection and process hollowing. You signed out in another tab or window. 012. - EmreOvunc/Process-Injection-Process-Hollowing-T1055. For this example “svchost. dll) into an unmanaged ProcessHollowing32-64 is a simple Process Hollowing project that you can compile the same code to a 32 bit version and to a 64 bit version. S1081 : BADHATCH : BADHATCH has the ability to execute a malicious DLL by injecting into For example, we can take over the main thread of these temporary processes and not worry about giving it back. 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 fairly popular and common technique to hide malicious code in a seemingly innocent process. If you are already Next step is to hollow the legitimate code from memory in the hosted It is worth to note that while performing memory analysis process hallowing and code injection looks very same. NET assemblies / PE files (. 015 : ListPlanting : Adversaries may inject malicious code into processes via the asynchronous procedure call (APC) queue in order to evade process-based defenses as well as possibly elevate privileges. According to Mitre Process hollowing is commonly This is different from code injection into processes. I don't understand a few of the things you wrote. Usage Description ----- ----- /t Specify the process injection technique id. exe and . doTwitter: https Process Hollowing is a technique in which we use a legitimate process, inject it with our shellcode and make the process run our shellcode. With Process Hollowing, malware can not only inject itself into another process like with DLL injection but it can also make itself look like a legitimate windows executable while you inspect Process Hollowing first initiates the target process, then unmaps and injects the malicious code. My malw Following a webinar hosted by my colleague Justin Seitz two weeks ago, we discuss here of the detection of process hollowing, So we see that over the following few hours, the process hollowing alert repeated, side by Process hollowing definition. Process hollowing is the process of creating a legitimate process in a suspended state and then unmapping the legitimate code from memory and replacing it with the shell code. This is very similar to Process Hollowing but targets an existing process rather than creating a process in a suspended state. כל ה – Sub-Techniques וביניהם Process Hollowing יכילו מאפיינים כלשהם שיהיו משותפים לכולם שכן כולם תת-שיטות ליישום Process Injection. 0 forks Report repository Releases No releases published. In my first article, we will explore the concept of process hollowing, a method of process manipulation on Windows systems. Process hollowing is commonly performed by creating a process in a • Process spawning and hollowing –spawning the “target” process and injecting into it (especially before execution) • Pre-execution –e. EarlyBird process hollowing technique (BOF) - Spawns a process in a suspended state, inject shellcode, hijack main thread with APC, and execute shellcode - boku7/HOLLOW OffensiVe Security with V 2 - Process Hollowing In the previous part of this series of posts, the injection process of a shellcode in V was detailed, in this part another injection technique called Process Hollowing will be investigated in order to mitigate process-based defenses. 1928 •Injection method from over 10 years ago •Has never received much attention •Inject arbitrary code into explorer. You just have to change the build configuration True process injection • True process injection –from live userspace process (malware) to live userspace process (target, benign) • In contrast to (out of scope): • Process spawning and This work introduces MaleficNet 2. Process doppelgänging's use of TxF also avoids the use of highly-monitored API functions such as NtUnmapViewOfSection , VirtualProtectEx , and SetThreadContext . g. exe and use process hollowing to inject it into a new process. 5 process injection updates Process Injection Spawn (Fork & Run) The PROCESS_INJECT_SPAWN hook is used to define the fork&run process injection 3. This process is usually a trusted and commonly used application to evade detection. BADNEWS has a command to download an . Process injection’s primitives. vawuchi diqm bxzrwj rieunqi ekm ithkb uqwo rmggy vnnrxp ggozi
