Introduction
System Monitor (Sysmon) is a Windows system service and devicedriver that, once installed on a system, remains resident across systemreboots to monitor and log system activity to the Windows event log. Itprovides detailed information about process creations, networkconnections, and changes to file creation time. By collecting the eventsit generates using Windows EventCollectionorSIEMagents and subsequently analyzing them, you can identify malicious oranomalous activity and understand how intruders and malware operate onyour network.
Note that Sysmon Bettertouchtool 2 297 – customize multi touch trackpad gestures. does not provide analysis of the events it generates,nor does it attempt to protect or hide itself from attackers.
Overview of Sysmon Capabilities
Sysmon includes the following capabilities:
- Logs process creation with full command line for both current andparent processes.
- Records the hash of process image files using SHA1 (the default),MD5, SHA256 or IMPHASH.
- Multiple hashes can be used at the same time.
- Includes a process GUID in process create events to allow forcorrelation of events even when Windows reuses process IDs.
- Includes a session GUID in each event to allow correlation of eventson same logon session.
- Logs loading of drivers or DLLs with their signatures and hashes.
- Logs opens for raw read access of disks and volumes.
- Optionally logs network connections, including each connection'ssource process, IP addresses, port numbers, hostnames and portnames.
- Detects changes in file creation time to understand when a file wasreally created. Modification of file create timestamps is atechnique commonly used by malware to cover its tracks.
- Automatically reload configuration if changed in the registry.
- Rule filtering to include or exclude certain events dynamically.
- Generates events from early in the boot process to capture activitymade by even sophisticated kernel-mode malware.

Usage
Uses Sysmon simple command-line options to install and uninstall it, aswell as to check and modify Sysmon's configuration:
Sysinternals Sysmon v11.0 - System activity monitor
Copyright (C) 2014-2020 Mark Russinovich and Thomas Garnier
Sysinternals - www.sysinternals.com
Usage:
Install: sysmon64 -i []
Update configuration: sysmon64 -c []
Install event manifest: sysmon64 -m
Print schema: sysmon64 -s
Uninstall: sysmon64 -u [force]
| Parameter | Description |
|---|---|
| -i | Install service and driver. Optionally take a configuration file. |
| -c | Update configuration of an installed Sysmon driver or dump the current configuration if no other argument is provided. Optionally take a configuration file. |
| -m | Install the event manifest (done on service install as well). |
| -s | Print configuration schema definition. |
| -u | Uninstall service and driver. Adding force causes uninstall to proceed even when some components are not installed. |
The service logs events immediately and the driver installs as aboot-start driver to capture activity from early in the boot that theservice will write to the event log when it starts.
On Vista and higher, events are stored in 'Applications and ServicesLogs/Microsoft/Windows/Sysmon/Operational'
On older systems, events are written to the System event log.
If you need more information on configuration files, use the '-? config'command. More examples are available on the Sysinternals website.
Specify -accepteula to automatically accept the EULA on installation,otherwise you will be interactively prompted to accept it.
Neither install nor uninstall requires a reboot.
Examples
Install with default settings (process images hashed with sha1 and nonetwork monitoring)
sysmon -accepteula -i
Install Sysmon with a configuration file (as described below)
sysmon -accepteula -i c:windowsconfig.xml

Events
On Vista and higher, events are stored in 'Applications and ServicesLogs/Microsoft/Windows/Sysmon/Operational', and on older systems eventsare written to the System event log. Event timestamps are in UTCstandard time.
The following are examples of each event type that Sysmon generates.
Event ID 1: Process creation
The process creation event provides extended information about a newlycreated process. The full command line provides context on the processexecution. The ProcessGUID field is a unique value for this processacross a domain to make event correlation easier. The hash is a fullhash of the file with the algorithms in the HashType field.
Event ID 2: A process changed a file creation time
The change file creation time event is registered when a file creationtime is explicitly modified by a process. This event helps tracking thereal creation time of a file. Attackers may change the file creationtime of a backdoor to make it look like it was installed with theoperating system. Note that many processes legitimately change thecreation time of a file; it does not necessarily indicate maliciousactivity.
Event ID 3: Network connection
The network connection event logs TCP/UDP connections on the machine. Itis disabled by default. Each connection is linked to a process throughthe ProcessId and ProcessGUID fields. The event also contains the sourceand destination host names IP addresses, port numbers and IPv6 status.
Event ID 4: Sysmon service state changed
The service state change event reports the state of the Sysmon service(started or stopped).
Event ID 5: Process terminated
The process terminate event reports when a process terminates. Itprovides the UtcTime, ProcessGuid and ProcessId of the process.
Event ID 6: Driver loaded
The driver loaded events provides information about a driver beingloaded on the system. The configured hashes are provided as well assignature information. The signature is created asynchronously forperformance reasons and indicates if the file was removed after loading.
Event ID 7: Image loaded
The image loaded event logs when a module is loaded in a specificprocess. This event is disabled by default and needs to be configuredwith the –l option. It indicates the process in which the module isloaded, hashes and signature information. The signature is createdasynchronously for performance reasons and indicates if the file wasremoved after loading. This event should be configured carefully, asmonitoring all image load events will generate a large number of events.
Event ID 8: CreateRemoteThread
The CreateRemoteThread event detects when a process creates a thread inanother process. This technique is used by malware to inject code andhide in other processes. The event indicates the source and targetprocess. It gives information on the code that will be run in the newthread: StartAddress, StartModule and StartFunction. Note thatStartModule and StartFunction fields are inferred, they might be emptyif the starting address is outside loaded modules or known exportedfunctions.
Event ID 9: RawAccessRead
The RawAccessRead event detects when a process conducts readingoperations from the drive using the . denotation. This techniqueis often used by malware for data exfiltration of files that are lockedfor reading, as well as to avoid file access auditing tools. The eventindicates the source process and target device.
Event ID 10: ProcessAccess
The process accessed event reports when a process opens another process,an operation that's often followed by information queries or reading andwriting the address space of the target process. This enables detectionof hacking tools that read the memory contents of processes like LocalSecurity Authority (Lsass.exe) in order to steal credentials for use inPass-the-Hash attacks. Enabling it can generate significant amounts oflogging if there are diagnostic utilities active that repeatedly openprocesses to query their state, so it generally should only be done sowith filters that remove expected accesses.
Event ID 11: FileCreate
File create operations are logged when a file is created or overwritten.This event is useful for monitoring autostart locations, like theStartup folder, as well as temporary and download directories, which arecommon places malware drops during initial infection.
Event ID 12: RegistryEvent (Object create and delete)
Registry key and value create and delete operations map to this eventtype, which can be useful for monitoring for changes to Registryautostart locations, or specific malware registry modifications.
Sysmon uses abbreviated versions of Registry root key names, with thefollowing mappings:
| Key name | Abbreviation |
|---|---|
| HKEY_LOCAL_MACHINE | HKLM |
| HKEY_USERS | HKU |
| HKEY_LOCAL_MACHINESystemControlSet00x | HKLMSystemCurrentControlSet |
| HKEY_LOCAL_MACHINEClasses | HKCR |
Event ID 13: RegistryEvent (Value Set)
This Registry event type identifies Registry value modifications. Theevent records the value written for Registry values of type DWORD andQWORD.
Event ID 14: RegistryEvent (Key and Value Rename)
Registry key and value rename operations map to this event type,recording the new name of the key or value that was renamed.
Event ID 15: FileCreateStreamHash
This event logs when a named file stream is created, and it generatesevents that log the hash of the contents of the file to which the streamis assigned (the unnamed stream), as well as the contents of the namedstream. There are malware variants that drop their executables orconfiguration settings via browser downloads, and this event is aimed atcapturing that based on the browser attaching a Zone.Identifier 'mark ofthe web' stream.

Event ID 16: ServiceConfigurationChange
This event logs changes in the Sysmon configuration - for example when thefiltering rules are updated.
Event ID 17: PipeEvent (Pipe Created)
This event generates when a named pipe is created. Malware often uses namedpipes for interprocess communication.
Event ID 18: PipeEvent (Pipe Connected)
This event logs when a named pipe connection is made between a client and aserver.
Event ID 19: WmiEvent (WmiEventFilter activity detected)
When a WMI event filter is registered, which is a method used by malware toexecute, this event logs the WMI namespace, filter name and filter expression.
Event ID 20: WmiEvent (WmiEventConsumer activity detected)
This event logs the registration of WMI consumers, recording the consumer name,log, and destination.
Event ID 21: WmiEvent (WmiEventConsumerToFilter activity detected)
When a consumer binds to a filter, this event logs the consumer name and filter path.
Event ID 22: DNSEvent (DNS query)
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 8.1 so it is not available on Windows 7 and earlier.
Event ID 23: FileDelete (A file delete was detected)
A file was deleted.
Event ID 24: ClipboardChange (New content in the clipboard)
This event is generated when the system clipboard contents change.
Event ID 25: ProcessTampering (Process image change)
This event is generated when a process image is changed from an external source, such as a different process.
Event ID 255: Error
This event is generated when an error occurred within Sysmon. They canhappen if the system is under heavy load and certain tasked could not beperformed or a bug exists in the Sysmon service. You can report any bugson the Sysinternals forum or over Twitter(@markrussinovich).
Configuration files
Configuration files can be specified after the -i (installation) or-c (installation) configuration switches. They make it easier todeploy a preset configuration and to filter captured events.
A simple configuration xml file looks like this:
The configuration file contains a schemaversion attribute on the Sysmontag. This version is independent from the Sysmon binary version andallows the parsing of older configuration files. You can get the currentschema version by using the '-? config' command line. Configurationentries are directly under the Sysmon tag and filters are under theEventFiltering tag.

Configuration Entries
Configuration entries are similar to command line switches and include the following Iclock pro 5 6 download free.
Configuration entries include the following:
| Entry | Value | Description |
|---|---|---|
| ArchiveDirectory | String | Name of directories at volume roots into which copy-on-delete files are moved. The directory is protected with a System ACL. (you can use PsExec from Sysinternals to access the directory using 'psexec -sid cmd'). Default: Sysmon |
| CheckRevocation | Boolean | Controls signature revocation checks. Default: True |
| CopyOnDeletePE | Boolean | Preserves deleted executable image files. Default: False |
| CopyOnDeleteSIDs | Strings | Comma-separated list of account SIDs for which file deletes will be preserved. |
| CopyOnDeleteExtensions | Strings | Extensions for files that are preserved on delete. |
| CopyOnDeleteProcesses | Strings | Process name(s) for which file deletes will be preserved. |
| DnsLookup | Boolean | Controls reverse DNS lookup. Default: True |
| DriverName | String | Uses specied name for driver and service images. |
| HashAlgorithms | Strings | Hash algorithm(s) to apply for hashing. Algorithms supported include MD5, SHA1, SHA256, IMPHASH and * (all). Default: None |
Command line switches have their configuration entry described in the Sysmon usageoutput. Parameters are optional based on the tag. If a command lineswitch also enables an event, it needs to be configured though itsfilter tag. Audio record pro 3 3 8 – best music recorder. You can specify the -s switch to have Sysmon print the fullconfiguration schema, including event tags as well as the field namesand types for each event. For example, here's the schema for theRawAccessRead event type:
Event filtering entries
Event filtering allows you to filter generated events. In many casesevents can be noisy and gathering everything is not possible. Forexample, you might be interested in network connections only for acertain process, but not all of them. You can filter the output on thehost reducing the data to collect.
Each event has its own filter tag under the EventFiltering node in aconfiguration file:
| ID | Tag | Event |
|---|---|---|
| 1 ProcessCreate | Process Create | |
| 2 FileCreateTime | File creation time | |
| 3 NetworkConnect | Network connection detected | |
| 4 n/a | Sysmon service state change (cannot be filtered) | |
| 5 ProcessTerminate | Process terminated | |
| 6 DriverLoad | Driver Loaded | |
| 7 ImageLoad | Image loaded | |
| 8 CreateRemoteThread | CreateRemoteThread detected | |
| 9 RawAccessRead | RawAccessRead detected | |
| 10 ProcessAccess | Process accessed | |
| 11 FileCreate | File created | |
| 12 RegistryEvent | Registry object added or deleted | |
| 13 RegistryEvent | Registry value set | |
| 14 RegistryEvent | Registry object renamed | |
| 15 FileCreateStreamHash | File stream created | |
| 16 n/a | Sysmon configuration change (cannot be filtered) | |
| 17 PipeEvent | Named pipe created | |
| 18 PipeEvent | Named pipe connected | |
| 19 WmiEvent | WMI filter | |
| 20 WmiEvent | WMI consumer | |
| 21 WmiEvent | WMI consumer filter | |
| 22 DNSQuery | DNS query | |
| 23 FileDelete | File Delete |
You can also find these tags in the event viewer on the task name.
The onmatch filter is applied if events are matched. It can be changedwith 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 canspecify both an include filter set and an exclude filter set for eachevent ID, where exclude matches take precedence.
Each filter can include zero or more rules. Each tag under the filtertag is a field name from the event. Rules that specify a condition forthe same field name behave as OR conditions, and ones that specifydifferent field name behave as AND conditions. Field rules can also useconditions to match a value. The conditions are as follows (all are caseinsensitive):
| Condition | Description |
|---|---|
| is | Default, values are equals |
| is any | The field is one of the ; delimited values |
| is not | Values are different |
| contains | The field contains this value |
| contains any | The field contains any of the ; delimited values |
| contains all | The field contains any of the ; delimited values |
| excludes | The field does not contain this value |
| excludes any | The field does not contain one or more of the ; delimited values |
| excludes all | The field does not contain any of the ; delimited values |
| begin with | The field begins with this value |
| end with | The field ends with this value |
| less than | Lexicographical comparison is less than zero |
| more than | Lexicographical comparison is more than zero |
| image | Match an image path (full path or only image name). For example: lsass.exe will match c:windowssystem32lsass.exe |
You can use a different condition by specifying it as an attribute. Thisexcludes network activity from processes with iexplore.exe in theirpath:
iexplore.exe
To have Sysmon report which rule match resulted in an event being logged, add names to rules:
iexplore.exe
You can use both include and exclude rules for the same tag, where exclude rules override include rules. Within arule, filter conditions have OR behavior, In the sample configuration shown earlier, the networking filter uses bothan include and exclude rule to capture activity to port 80 and 443 by all processes except those that haveiexplore.exe in their name.
It is also possible to override the way that rules are combined by using a rule group which allows the rule combinetype for one or more events to be set explicity to AND or OR.
The following example demonstrates this usage. In the first rule group, a process create event will generate whentimeout.exe is executed only with a command - line argument of '100', but a process terminate event will generate fortermination of ping.exe and timeout.exe.
