You can either enter an X and Y coordinate of a click point, move your mouse cursor to a specific location on the screen and press ‘Current Cursor fixed Location’. Target Points are fixed spots on the screen where the clicker will click.
Process injection improves stealth, and some techniques also achieve persistence. Process injection is a widespread defense evasion technique employed often within malware and fileless adversary tradecraft, and entails running custom code within the address space of another process. Simplehat software llc brings you best auto clicker app android 2020 and this app will automat repetitive clicks. Auto clicker does not require root access.
The latter two are undocumented. Finally, to have the code executed in another process, the malware calls APIs such as CreateRemoteThread, NtCreateThreadEx, or RtlCreateUserThread. The malware then calls WriteProcessMemory to write the path in the allocated memory. After finding the target process, the malware gets the handle of the target process by calling OpenProcess.As shown in Figure 1, the malware calls VirtualAllocEx to have a space to write the path to its DLL.
One advantage of PE injection over the LoadLibrary technique is that the malware does not have to drop a malicious DLL on the disk. PORTABLE EXECUTABLE INJECTION (PE INJECTION)Instead of passing the address of the LoadLibrary, malware can copy its malicious code into an existing open process and cause it to execute (either via a small shellcode, or by calling CreateRemoteThread). The screenshot below displays a malware named Rebhip performing this technique.Figure 1: Rebhip worm performing a typical DLL injection Sha256: 07b8f25e7b536f5b6f686c12d04edc37e11347c8acd5c53f98a174723078c3652. Considering that attackers are most commonly injecting code to evade defenses, sophisticated attackers probably will not use this approach. Further, it requires a malicious DLL on disk which could be detected.
They do not rely on any extra Windows APIs (e.g., CreateRemoteThread or LoadLibrary), because they load and execute themselves in the memory. However, memory module and reflective DLL injection approaches are even stealthier. To overcome this, the malware needs to find its relocation table address in the host process, and resolve the absolute addresses of the copied image by looping through its relocation descriptors.This technique is similar to other techniques, such as reflective DLL injection and memory module, since they do not drop any files to the disk. When a malware injects its PE into another process it will have a new base address which is unpredictable, requiring it to dynamically recompute the fixed addresses of its PE. However, the obstacle with this approach is the change of the base address of the copied image. VirtualAllocEx), and instead of writing a “DLL path” it writes its malicious code by calling WriteProcessMemory.
The code has two nested loops to adjust its relocation table that can be seen before the calls to WriteProcessMemory and CreateRemoteThread. In Figure 2, the sample unit test is taking advantage of this technique. This technique is quite popular among crypters (softwares that encrypt and obfuscate malware). In a previous blog post, these two in memory approaches were discussed extensively.When analyzing PE injection, it is very common to see loops (usually two “for” loops, one nested in the other), before a call to CreateRemoteThread. Memory Module is similar to Reflective DLL injection except the injector or loader is responsible for mapping the target DLL into memory instead of the DLL mapping itself.
As shown in Figure 3, this is done by calling CreateProcess and setting the Process Creation Flag to CREATE_SUSPENDED (0x00000004). Process hollowing occurs when a malware unmaps (hollows out) the legitimate code from memory of the target process, and overwrites the memory space of the target process (e.g., svchost.exe) with a malicious executable.The malware first creates a new process to host the malicious code in suspended mode. PROCESS HOLLOWING (A.K.A PROCESS REPLACEMENT AND RUNPE)Instead of injecting code into a host program (e.g., DLL injection), malware can perform a technique known as process hollowing. Now that the malware has recomputed all the necessary addresses, all it needs to do is pass its starting address to CreateRemoteThread and have it executed.Figure 2: Example structure of the loops for PE injection prior to calls to CreateRemoteThread Sha256: ce8d7590182db2e51372a4a04d6a0927a65b2640739f9ec01cfd6c143b1110da3.
These two APIs basically release all memory pointed to by a section. This is done by unmapping the memory of the target process by calling either ZwUnmapViewOfSection or NtUnmapViewOfSection. Next, the malware needs to swap out the contents of the legitimate file with its malicious payload.
Therefore, during analysis you will probably see calls to CreateToolhelp32Snapshot and Thread32First followed by OpenThread.After getting a handle to the target thread, the malware puts the thread into suspended mode by calling SuspendThread to perform its injection. In thread execution hijacking, malware targets an existing thread of a process and avoids any noisy process or thread creations operations. THREAD EXECUTION HIJACKING (A.K.A SUSPEND, INJECT, AND RESUME (SIR))This technique has some similarities to the process hollowing technique previously discussed. At the end, the malware resumes the suspended thread by calling ResumeThread to take the process out of suspended state.Figure 3: Ransom.Cryak performing process hollowing Sha256: eae72d803bf67df22526f50fc7ab84d838efb2865c27aef1a61592b1c520d1444. The malware calls SetThreadContext to point the entrypoint to a new code section that it has written.
To avoid this, a more sophisticated malware would resume and retry later if the EIP register is within the range of NTDLL.dll.Figure 4: A generic trojan is performing thread execution hijacking Sha256:787cbc8a6d1bc58ea169e51e1ad029a637f22560660cc129ab8a099a745bd50eHooking is a technique used to intercept function calls. From the attacker’s perspective, the SIR approach can be problematic because suspending and resuming a thread in the middle of a system call can cause the system to crash. Afterwards, malware resumes the thread to execute the shellcode that it has written to the host process. In order to hijack the execution of the thread, the malware modifies the EIP register (a register that contains the address of the next instruction) of the targeted thread by calling SetThreadContext. The code can contain shellcode, the path to the malicious DLL, and the address of LoadLibrary.Figure 4 illustrates a generic trojan using this technique.

The events reflect the range of hook types, and vary from pressing keys on the keyboard (WH_KEYBOARD) to inputs to the mouse (WH_MOUSE), CBT, etc. The first argument is the type of event. The SetWindowsHookEx function takes four arguments. This is usually done by calling SetWindowsHookEx to install a hook routine into the hook chain.
If this value is set to zero all threads perform the action when the event is triggered. The last argument to this function is the thread with which the hook procedure is to be associated. Thus, it is very common to see calls to LoadLibrary and GetProcAddress before calling SetWindowsHookEx.
