As we have described earlier, the prime matter of interest is to get the details about the message box activation code. Here, we can easily identify the first message box occurrence after the E offset. Well, this code manipulates a couple of other message boxes indeed.
But we have to recognize the very first message box. So, we will search at E offset in the OllyDbg to find the message box assembly code in order to modify it to suit our need. We can duly confirm the message box occurrence by placing a breakpoint at E in IDA Pro and start debugging. If we entered a short name, then the graph view of the assembly code clearly indicates the execution flow toward the message box code as follows:.
Open the victim. Every executable has some empty space referred to as Code Caves where we can place or inject any external binary code. So, if you scroll down a little bit, you will easily identify the blank area named as DB 00 or NOP in the assembly code. As from the aforesaid figure 1. So, we shall place our external spyware code in these code caves. Select a couple code caves instructions and right click, choose Binary and then edit as follows:. Now, label the spyware program executable as spyware.
Its corresponding hex code is automatically generated and placed at the A offset. After pressing the OK button in figure 1. Now, we have to write the spyware offset address value into memory. However, move forward just one step and at offset , press space bar button.
Here, we found assemble code box. Here, notice that we are giving the reference of spyware. So we have to instruct the Assembly code by calling the CALL WinExec instruction: we are injecting an external executable which has of course. After finishing with arbitrary code injection related to spyware, the modified assembly looks like the following:.
As referenced in figure 1. This action directly lets us reach the entry point of the first message box as follows. Here, we have to perform some significant modifications. Now, select the E offset and press space bar, then copy the JNB instruction into the clipboard as follows:. We shall discuss shortly what we are doing. Ok, now copy the offset address in the clipboard from the First PUSH 1 in the new injected code.
Again go to offset E where the message box code is located, select the instruction set at E, and press the space bar. Finally, replace the existing code with new. Assemble the JNB instruction here. So, what are we actually doing here? First we are giving the reference of the PUSH 1 instruction offset to the jump instruction located at offset E. Secondly, pasting the JNB instruction to the A1 offset as follows:. Basically, the aforesaid figure indicates that after entering the user name and serial key in the victim.
We have finished with the code injections tactics. Now make changes permanent and write the modified bytes into memory by right clicking on the ASM code and select the Copy to Executable option, where we choose All Modifications as follows:.
Now, select the Copy all option in the forthcoming dialog box, which produces a separate dialog box as follows, where the final assemble code collectively resides. There are many reasons why you are seeing winagent. They slow down the whole system and also cause. This occurs because they modify the registry which is very important in the proper functioning of processes. Incomplete installation Another common reason behind winagent. It can happen because of errors during installation, lack of hard disk space, and crash during install.
This also leads to a corrupted registry causing the error. The solution to fixing winagent. Run a registry cleaner to repair and remove the Windows registry that is causing winagent. Is a winagent.

Watch our Welcome Guide to learn how to use this site. Joined Jul 26, Messages So I have been noticing the last couple of days that my computer seems to be moving extra slow like mollases actually. I did a scane with superantispyware and didnt get any results escept for tracking cookies. Last night though I did a scan with spyware search and destroy and got two listings one for winagent.
Can someone take alook at my HJT log and see whats going on my computer is freezing alot and doing strange things im kinda concerned.
