DETECTION OVERVIEW
Risk Factors
NetExec is a common attack tool due to its extensive functionality and flexibility. While some NetExec features are relatively low risk, such as network reconnaissance, others features such as lateral movement and credential access are higher risk. Ultimately, unless this activity is part of an authorized security assessment, NetExec activity should be investigated before it enables critical and costly attacks.
Kill Chain
Risk Score
60
NetExec is a post-exploitation tool with extensive capabilities. An attacker runs NetExec to establish an SMB connection to the target device and performs NTLM authentication. Upon successful authentication, NetExec can test stolen credentials, enumerate Active Directory information, laterally move to other computers, and even dump credentials with techniques like DCSync.
Prevent NetExec activity with features such as AppLocker, application control, script blocking, and other prevention mechanisms
Reduce the number of users that have local administrator privileges
Restrict file share access to only authorized IP addresses
