administrators may create windows services on remote systems, but this activity is usually limited to a small set of hosts or users.	t1543 t1543.003 endpoint splunk
administrators may start windows services on remote systems, but this activity is usually limited to a small set of hosts or users.	t1543 t1543.003 endpoint splunk
although uncommon, administrators may leverage impackets tools to start a process on remote systems for system administration or automation use cases.	t1021 t1021.002 t1021.003 t1047 t1543.003 endpoint splunk
false positives may arise in the rdp hijacking analytic when legitimate administrators access remote sessions for maintenance or troubleshooting purposes. these activities might resemble an attacker''s attempt to hijack a disconnected session, leading to false alarms. to mitigate the risk of false positives and improve the overall security posture, organizations can implement group policy to automatically disconnect rdp sessions when they are complete. by enforcing this policy, administrators ensure that disconnected sessions are promptly terminated, reducing the window of opportunity for an attacker to hijack a session. additionally, organizations can also implement access control mechanisms and monitor the behavior of privileged accounts to further enhance security and reduce the chances of false positives in rdp hijacking detection.	t1543.003 t1563 t1563.002 endpoint splunk
false positives may be present based on common applications adding new drivers, however, filter as needed.	t1068 t1543 t1543.003 endpoint splunk
false positives may be present, filter as needed based on administrative activity.	t1543 t1543.003 endpoint splunk
false positives may occur if one of the vulnerable driver names mentioned above didn't change its name between versions. so always make sure that the driver being loaded is the legitimate one and the non vulnerable version.	t1068 t1543 t1543.003 windows sigma
false positives should be limited as this is specific to krbrelayup based attack. filter as needed.	t1543.003 endpoint splunk
false positives should be limited.	t1543 t1543.003 endpoint splunk
false positives will be present. drill down into the driver further by version number and cross reference by signer. review the reference material in the lookup. in addition, modify the query to look within specific paths, which will remove a lot of \"normal\" drivers.	t1543.003 endpoint splunk
if you experience a lot of fp you could comment the driver name or its exact known legitimate location (when possible)	t1068 t1543 t1543.003 windows sigma

legitimate applications may install services with uncommon services paths.	t1543 t1543.003 t1569 t1569.002 endpoint splunk

limited false positives will be present. some applications do load drivers	t1543 t1543.003 endpoint splunk
note that false positives may occur, and filtering may be necessary, especially when it comes to remote service creation by administrators or software management utilities.	t1543 t1543.003 endpoint splunk

the rule doesn't look for anything suspicious so false positives are expected. if you use one of the tools mentioned, comment it out	t1543 t1543.003 t1569 t1569.002 windows sigma

using sc.exe to manipulate windows services is uncommon. however, there may be legitimate instances of this behavior. it is important to validate and investigate as appropriate.	t1543 t1543.003 endpoint splunk
