In September 2019 alone, Symantec blocked more than 480,000 malicious PowerShell scripts on endpoints. This revealed that WMI, the command line tool, and PowerShell were most frequently used for malicious purposes, accounting for 89 percent of all dual-use tools used as downloaders. We also looked at more than 500,000 dual-use tool detections from the beginning of September 2019, which were either used to download or copy payloads to target computers. To do this, we extract execution patterns from our data with the help of advanced machine learning, and the data is then analyzed by our AI-based Targeted Attack Analytics (TAA) component.
The context and execution sequence must be considered when determining if usage is malicious or benign.
However, only a fraction of the overall usage of these tools was malicious. The most frequently executed tools observed by Symantec in Q1 2019 were net.exe, PowerShell, the certification utility, the task scheduler, and the WMI command line (WMIC). Symantec has previously published research that gives a general overview of living-off-the-land tactics and fileless attack techniques however, our new research provides updated statistics on the dual-use tools utilized in these attacks-with a focus on PowerShell and Windows Management Instrumentation (WMI)-and how they are currently being used by different attack groups.
When done then you can move it back to its regular group.“Living-off-the-land” tactics-where attackers take advantage of native tools and services already present on targeted systems-have been used by both targeted attack groups and common cyber criminal gangs for some time now. When you're ready to troubleshoot just move the client into the custom group. When troubleshooting, you're best off creating a group in SEPM that allows you to disable components. Opening the locks for the various components with all allow you to right click the icon and 'Disable SEP' In your AV policy you need to either uncheck the box for auto-protect or open the lock so it can be disabled at the client end. The Client Intrusion Detection System (CIDS).The Network Threat Protection (NTP) Firewall.
Stopping SMC disables the following features: Issuing the smc -stop command stops the Symantec Management Client (SMC.exe) and the Symantec Endpoint Protection service (ccsvchst.exe). What functions of the Symantec Endpoint Protection client are disabled by the smc -stop command? That's because doing an 'smc -stop' does not stop the auto-protection function.
