itman 1,602 Posted April 9, 2019 Share Posted April 9, 2019 Eset has no use for that process but malware can be deployed via it: https://lolbas-project.github.io/lolbas/Binaries/Atbroker/ You might want to use SysInternals Autoruns and see if you can find any reference to AtBroker.exe in any of the Windows startup locations; e.g. registry keys, startup directories, etc.. Is your copy of Eset legit and downloaded from the Eset web site? Link to comment Share on other sites More sharing options...

itman 1,602 Posted April 9, 2019 Share Posted April 9, 2019 Use of Windows "Assistive Technologies" such as Magnifier, On-Screen Keyboard, etc.. are most likely the reason for AtBroker.exe to load at boot time. Are you using any of those features? Link to comment Share on other sites More sharing options...

itman 1,602 Posted April 9, 2019 Share Posted April 9, 2019 (edited) If you don't want to use Autoruns to determine what is starting AtBroker.exe at boot time, do the following. Create on a test basis an Eset HIPS rule to allow the startup of AtBroker.exe. Make sure you enable logging for the rule and set its severity level to "Warning." After you boot, check the Eset HIPS log for any log entries from this rule. Those entries will inform you what process is starting AtBroker.exe. You can now delete the HIPS rule for AtBroker.exe. If ekrn.exe is not starting AtBroker.exe, then Eset is not the source of the activity. Edited April 9, 2019 by itman Link to comment Share on other sites More sharing options...

itman 1,602 Posted April 10, 2019 Share Posted April 10, 2019 (edited) In regards to the HIPS rule it should begin with "User rule:" followed by some descriptive text. For example; User rule: allow atbroker.exe startup As far as the first rule screen goes: Action = Allow Operations affecting - checkmark "Applications" Enabled - checkmark Logging severity - Warning Click on the "Next" tab The next screen shown is titled "Source Applications" In the drop down box select "All Applications" Click on the "Next" tab The next screen shown is titled "Application Operations" Check mark "Start New Application" Click on the "Next" tab The next screen shown is titled "Applications" Click on the "Add" tab Enter both atbroker.exe files from windows system32 and syswow64 directories Click on the "Finish" button Click on any subsequently displayed "OK" button to save your newly created rule. Verify your newly created HIPS rule conforms to the above settings by reopening the HIPS rule you just created.
