Query Details
# Statistics LOLBIN usage ## Query Information #### Description List the the statistics of LOLBINS that have been executed. Mostly the rare lolbins are most interesting to why and whom executed them. The list of LOLBINS is based on the lolbas project. #### References - https://lolbas-project.github.io/ ## Defender For Endpoint ``` let LOLBins = dynamic(["AppInstaller.exe", "Aspnet_Compiler.exe", "At.exe", "Atbroker.exe", "Bash.exe", "Bitsadmin.exe", "CertOC.exe", "CertReq.exe", "Certutil.exe", "Cmd.exe", "Cmdkey.exe", "cmdl32.exe", "Cmstp.exe", "ConfigSecurityPolicy.exe", "Conhost.exe", "Control.exe", "Csc.exe", "Cscript.exe", "CustomShellHost.exe", "DataSvcUtil.exe", "Desktopimgdownldr.exe", "DeviceCredentialDeployment.exe", "Dfsvc.exe", "Diantz.exe", "Diskshadow.exe", "Dnscmd.exe", "Esentutl.exe", "Eventvwr.exe", "Expand.exe", "Explorer.exe", "Extexport.exe", "Extrac32.exe", "Findstr.exe", "Finger.exe", "fltMC.exe", "Forfiles.exe", "Ftp.exe", "Gpscript.exe", "Hh.exe", "IMEWDBLD.exe", "Ie4uinit.exe", "Ieexec.exe", "Ilasm.exe", "Infdefaultinstall.exe", "Installutil.exe", "Jsc.exe", "Ldifde.exe", "Makecab.exe", "Mavinject.exe", "Msedge.exe", "Microsoft.Workflow.Compiler.exe", "Mmc.exe", "MpCmdRun.exe", "Msbuild.exe", "Msconfig.exe", "Msdt.exe", "Mshta.exe", "Msiexec.exe", "Netsh.exe", "Odbcconf.exe", "OfflineScannerShell.exe", "OneDriveStandaloneUpdater.exe", "Pcalua.exe", "Pcwrun.exe", "Pktmon.exe", "Pnputil.exe", "Presentationhost.exe", "Print.exe", "PrintBrm.exe", "Psr.exe", "Rasautou.exe", "rdrleakdiag.exe", "Reg.exe", "Regasm.exe", "Regedit.exe", "Regini.exe", "Register-cimprovider.exe", "Regsvcs.exe", "Regsvr32.exe", "Replace.exe", "Rpcping.exe", "Rundll32.exe", "Runexehelper.exe", "Runonce.exe", "Runscripthelper.exe", "Sc.exe", "Schtasks.exe", "Scriptrunner.exe", "Setres.exe", "SettingSyncHost.exe", "Stordiag.exe", "SyncAppvPublishingServer.exe", "Ttdinject.exe", "Tttracer.exe", "Unregmp2.exe", "vbc.exe", "Verclsid.exe", "Wab.exe", "winget.exe", "Wlrmdr.exe", "Wmic.exe", "WorkFolders.exe", "Wscript.exe", "Wsreset.exe", "wuauclt.exe", "Xwizard.exe", "fsutil.exe", "wt.exe", "GfxDownloadWrapper.exe", "Advpack.dll", "Desk.cpl", "Dfshim.dll", "Ieadvpack.dll", "Ieframe.dll", "Mshtml.dll", "Pcwutl.dll", "Setupapi.dll", "Shdocvw.dll", "Shell32.dll", "Syssetup.dll", "Url.dll", "Zipfldr.dll", "Comsvcs.dll", "AccCheckConsole.exe", "adplus.exe", "AgentExecutor.exe", "Appvlp.exe", "Bginfo.exe", "Cdb.exe", "coregen.exe", "Createdump.exe", "csi.exe", "DefaultPack.EXE", "Devinit.exe"]); DeviceProcessEvents | where InitiatingProcessFileName in~ (LOLBins) | summarize TotalExecutions = count() by InitiatingProcessFileName | sort by TotalExecutions ``` ## Sentinel ``` let LOLBins = dynamic(["AppInstaller.exe", "Aspnet_Compiler.exe", "At.exe", "Atbroker.exe", "Bash.exe", "Bitsadmin.exe", "CertOC.exe", "CertReq.exe", "Certutil.exe", "Cmd.exe", "Cmdkey.exe", "cmdl32.exe", "Cmstp.exe", "ConfigSecurityPolicy.exe", "Conhost.exe", "Control.exe", "Csc.exe", "Cscript.exe", "CustomShellHost.exe", "DataSvcUtil.exe", "Desktopimgdownldr.exe", "DeviceCredentialDeployment.exe", "Dfsvc.exe", "Diantz.exe", "Diskshadow.exe", "Dnscmd.exe", "Esentutl.exe", "Eventvwr.exe", "Expand.exe", "Explorer.exe", "Extexport.exe", "Extrac32.exe", "Findstr.exe", "Finger.exe", "fltMC.exe", "Forfiles.exe", "Ftp.exe", "Gpscript.exe", "Hh.exe", "IMEWDBLD.exe", "Ie4uinit.exe", "Ieexec.exe", "Ilasm.exe", "Infdefaultinstall.exe", "Installutil.exe", "Jsc.exe", "Ldifde.exe", "Makecab.exe", "Mavinject.exe", "Msedge.exe", "Microsoft.Workflow.Compiler.exe", "Mmc.exe", "MpCmdRun.exe", "Msbuild.exe", "Msconfig.exe", "Msdt.exe", "Mshta.exe", "Msiexec.exe", "Netsh.exe", "Odbcconf.exe", "OfflineScannerShell.exe", "OneDriveStandaloneUpdater.exe", "Pcalua.exe", "Pcwrun.exe", "Pktmon.exe", "Pnputil.exe", "Presentationhost.exe", "Print.exe", "PrintBrm.exe", "Psr.exe", "Rasautou.exe", "rdrleakdiag.exe", "Reg.exe", "Regasm.exe", "Regedit.exe", "Regini.exe", "Register-cimprovider.exe", "Regsvcs.exe", "Regsvr32.exe", "Replace.exe", "Rpcping.exe", "Rundll32.exe", "Runexehelper.exe", "Runonce.exe", "Runscripthelper.exe", "Sc.exe", "Schtasks.exe", "Scriptrunner.exe", "Setres.exe", "SettingSyncHost.exe", "Stordiag.exe", "SyncAppvPublishingServer.exe", "Ttdinject.exe", "Tttracer.exe", "Unregmp2.exe", "vbc.exe", "Verclsid.exe", "Wab.exe", "winget.exe", "Wlrmdr.exe", "Wmic.exe", "WorkFolders.exe", "Wscript.exe", "Wsreset.exe", "wuauclt.exe", "Xwizard.exe", "fsutil.exe", "wt.exe", "GfxDownloadWrapper.exe", "Advpack.dll", "Desk.cpl", "Dfshim.dll", "Ieadvpack.dll", "Ieframe.dll", "Mshtml.dll", "Pcwutl.dll", "Setupapi.dll", "Shdocvw.dll", "Shell32.dll", "Syssetup.dll", "Url.dll", "Zipfldr.dll", "Comsvcs.dll", "AccCheckConsole.exe", "adplus.exe", "AgentExecutor.exe", "Appvlp.exe", "Bginfo.exe", "Cdb.exe", "coregen.exe", "Createdump.exe", "csi.exe", "DefaultPack.EXE", "Devinit.exe"]); DeviceProcessEvents | where InitiatingProcessFileName in~ (LOLBins) | summarize TotalExecutions = count() by InitiatingProcessFileName | sort by TotalExecutions ```
The query lists the statistics of LOLBINS that have been executed, focusing on the rare ones and identifying who executed them. LOLBINS are based on the lolbas project. The query is run in both Defender for Endpoint and Sentinel. It retrieves the total number of executions for each LOLBIN and sorts them by the total number of executions.
