Malware often uses named pipes for interprocess communication. When a WMI event filter is registered, which is a method used by malware to execute, this event logs the WMI namespace, filter name and filter expression.

This event logs the registration of WMI consumers, recording the consumer name, log, and destination. This event is generated when a process executes a DNS query, whether the result is successful or fails, cached or not. The telemetry for this event was added for Windows 8. A file was deleted. Under normal operating conditions this directory might grow to an unreasonable size - see event ID FileDeleteDetected for similar behavior but without saving the deleted files.

This event is generated when process hiding techniques such as "hollow" or "herpaderp" are being detected. This event is generated when an error occurred within Sysmon. They can happen if the system is under heavy load and certain tasked could not be performed or a bug exists in the Sysmon service. You can report any bugs on the Sysinternals forum or over Twitter markrussinovich. Configuration files can be specified after the -i installation or -c installation configuration switches.

They make it easier to deploy a preset configuration and to filter captured events. The configuration file contains a schemaversion attribute on the Sysmon tag.

This version is independent from the Sysmon binary version and allows the parsing of older configuration files. Configuration entries are directly under the Sysmon tag and filters are under the EventFiltering tag. Command line switches have their configuration entry described in the Sysmon usage output. Parameters are optional based on the tag. If a command line switch also enables an event, it needs to be configured though its filter tag.

You can specify the -s switch to have Sysmon print the full configuration schema, including event tags as well as the field names and types for each event. Event filtering allows you to filter generated events. In many cases events can be noisy and gathering everything is not possible. For example, you might be interested in network connections only for a certain process, but not all of them. You can filter the output on the host reducing the data to collect.

The onmatch filter is applied if events are matched. It can be changed with the onmatch attribute for the filter tag. If the value is "include" , it means only matched events are included. If it is set to "exclude" , the event will be included except if a rule match. You can specify both an include filter set and an exclude filter set for each event ID, where exclude matches take precedence.

Each filter can include zero or more rules. Each tag under the filter tag is a field name from the event. Rules that specify a condition for the same field name behave as OR conditions, and ones that specify different field name behave as AND conditions. Field rules can also use conditions to match a value.

The conditions are as follows all are case insensitive :. You can use a different condition by specifying it as an attribute. Windows services are ideal for long-running functionality that does not interfere with other users who are working on the same computer. For example, in a Windows Service application, we can use a FileSystemWatcher to listen to the file system change notifications and raise events when a directory, or a file in a directory, changes.

The beauty is that the Windows Service application handles all the events in the background. Practically, we usually run services in the security context of a specific user account that is different from the logged-on user or the default computer account. So a hacker cannot easily mess up the file system or the service related database through a compromised computer.

If you have created a Windows Service application in. NET framework, then you must remember the pain of debugging the Windows Service application. During those old days, the tool TopShelf helped us a little bit, but not much. Now, with. In my opinion, the concept of a Windows Service is clearer as well.

In order to follow along, you need to have. We will use the worker service template from. NET Core as a starting point. If you are using Visual Studio, then you can follow the steps below: 1 Create a new project. Select Next. Then select Create. If you are using. In order to enable the worker service app to run as a Windows Service, we need to update the project a little bit by doing the following steps:. In the code above, line 10 is the key to creating a Windows Service app.

Through these simple steps, we have created an ASP. Moreover, this app is automatically a Console application that we can run directly via executing the Demo. This setup allows us to debug the application as a Console app, and allows us to host the app in a Windows Service with minimum configurations. Bonus: we can check if the app is running as a Windows Service or not using the bool WindowsServiceHelpers.

IsWindowsService method, which returns true if the current process is hosted as a Windows Service, otherwise false. Logging is essential for monitoring the status of our application. In this application, we will use Serilog to log messages to both Console output and physical files.

We will need to install the following NuGet packages that are related to Serilog: Serilog. Thread , Serilog. Hosting , Serilog. Console , and Serilog. All of these NuGet packages should use their latest versions. Then we update the Main method in the Program. In the code snippet above, we added two logging sinks: 1 Console line 10 with color theme, and 2 plain text files line 11 that are rolling every day.

The logging messages are enriched with ThreadID and LogContext , which are two common fields that can help us diagnosing issues if any. In the end, we add the line 44,. UseSerilog , to the HostBuilder , so that the host will use Serilog as a logging provider.

Caveat : By default, the log file path in line 11 should be able to use a relative path with respect to the assembly entry file. So I used an absolute path, with respect to AppDomain. BaseDirectory , to make sure the log files are written and saved into the proper location.

Now, if we run the application, we should be able to see both Console outputs and a log file with all logging messages.
