![]() ![]() When this is done, a new column will appear to the right, telling you if each process image is verified or not. This is a good next step to take if you have a process which was flagged as malicious by Virustotal, so that you can better determine if the process really is malicious. We can do this by navigating to the Options tab at the top of the tool and selecting the Verify Image Signatures section. This will submit the hash of every process running on the system to Virus Total and will check for any malicious processes.įinally, we can verify all image signatures for each process. From here, select the tab and then select the Check. If we want to check all process running on our system for potential malicious processes, we can navigate to the top of the tool and click on the Options tab. If a process returns with a number of Antivirus engines flagging it as malicious, this should be cause for further investigation. The result returned shows that 0 out of the 74 Antivirus engines categorised this process as malicious. Ideally, you want every process to return as 0/74.Īs you can see from the screenshot above, I scanned the “explorer.exe” process with Virus Total. This heading will show the number of antivirus services that have flagged that particular process as a potential virus. You may now notice that there is a new heading at the top of this tool called Virus Total. Simply accept the terms and this window will close. You will then be presented with the VirusTotal terms of service. We can do this by right clicking on the process and navigating to the Check VirusTotal section. ![]() If you have identified a process which looks suspicious, we can scan Virus Total for this process to determine if it is in fact malicious. This will open your default browser and search for the name of the process. We can search for the name of a particular process by right clicking on the process and navigating to the Search Online section at the bottom. Be careful when doing this, as setting a process to be considered as a low priority when it should be a high priority process could cause performance issues in your machine. You can set the level of priority your system places on a particular process by right clicking on the process and navigating to the Set Priority section. When you first open the tool, you will see every process currently running on your system. I will then demonstrate how you would scan a suspicious process using VirusTotal to determine if it is malicious. We will use this tool to analyse the process running on our Windows machines. This can be done from the following link: The first step for this lab is to download the Process Explorer tool. You can use a Windows machine for this lab. Process explorer is used as a free advanced task manager and system monitor. This is a set of more than 70 free tools used to monitor, manage, and troubleshoot the Windows operating system. Process Explorer is a tool which is part of the Microsoft Windows Sysinternals suite. Sigcheck v2.03: This version corrects a bug that caused the output of the –u switch to include signed files, and fixes several other minor bugs.Learn how to use Process Explorer to find and scan suspicious processes for malware in Windows. For a good triage picture when running a sample you would ideally want to use Process Hacker, Process Monitor, Autoruns, and a traffic capture tool of. Autoruns is a completely different tool and would be run alongside Process Hacker. PSExec v2.1: This update to PsExec, a command-line utility that enables you to execute programs on remote systems without preinstalling an agent, encrypts all communication between local and remote systems, including the transmission of command information such as the user name and password under which the remote program executes. Process Hacker is just an enhanced version of Process Explorer, so I always just default to process Hacker. Process Monitor v.3.1: This release adds registry create file disposition (create vs open) and a new switch, /saveapplyfilter, which has Process Monitor apply the current filter to the output file as it saves it. Process Explorer v16.02: This minor update adds a refresh button to the thread’s stack dialog and ensures that the Virus Total terms of agreement dialog box remains above the main Process Explorer window. Here's what's new, changed, and updated (with links): Over the weekend, Sysinternals creator, Mark Russinovich, announced on Twitter that four applications in the popular utility bundle have been updated. ![]()
