![]() As we will see later, this means we can sometimes directly correlate logs with ETW events. ![]() Since Windows Vista, the Windows Event Log has been built on top of ETW and both log events and ETW events have similar metadata associated with them. ![]() This makes it a great telemetry source for attack detection. ETWĮvent Tracing for Windows (ETW) is a kernel-level tracing facility built into Windows that allows a wide range of system activity to be traced in real time. We will use this as an opportunity to explore Event Tracing for Windows (ETW), as well as how RPC calls work in Windows.Īfter a primer on ETW, we’ll look first at two built-in Windows utilities for creating a service, sc.exe and WMI, and then look at the Sysinternals tool PsExec, which uses remote service creation as a way of executing commands on a remote host. In this article, we’ll explore remote service creation as a lateral movement technique, and illustrate how we might spot it on an endpoint. But if they can detect the lateral movement as it is happening it can be much quicker to see how the attacker is moving around, decreasing response times and possibly providing opportunities for quick containment actions. If threat hunters can detect malicious activity on an endpoint they may see similar indicators appearing on new machines when lateral movement has occurred. If I run psexec.Lateral movement is when attackers move from a compromised host to other hosts to expand their access and reach their goal. The first is that the share is no longer writable. ![]() ![]() So what does it look like now? There were two changes I can see. The box was patched last night (Jan 25 2020). I’ll notice right away that the first ACE string gives all authenticated users the same permissions that the last string gives to administrators. This table breaks down the six DACL rights as given: ACEĪllow Directory Create Child, List, Read Properties, and Generic ReadĪllow Directory Create Child, List, Read Properties, and Generic Read, and Property Write This is to allow all authenticated users CC, which is a directory service object access right for SDDL_CREATE_CHILD or create child items. ![]()
