5 detections

This rule detects the execution of common Windows command-line utilities used for system network configuration discovery. Adversaries often use these commands to gather information about the network environment, including IP addresses, network interfaces, ARP tables, NetBIOS information, and routing tables. The specific commands monitored are 'ipconfig /all', 'netsh interface show interface', 'arp -a', 'nbtstat -n', 'net config', and 'route print'.

Use this query to find reconnaissance and beaconing activities after code injection occurs.
Reconnaissance commands are consistent with the current version of Qakbot and occur automatically to exfiltrate system information. This data, once exfiltrated, will be used to prioritize human operated actions.

The following analytic detects suspicious system network configuration discovery activities, which may indicate an adversary's attempt to gather information about the network environment. Such actions typically involve commands or tools used to identify network interfaces, routing tables, and active connections. Detecting these activities is crucial, as they often precede more targeted attacks like lateral movement or data exfiltration. By identifying unusual or unauthorized network discovery efforts, this analytic helps security teams to swiftly detect and respond to potential reconnaissance operations, mitigating the risk of further compromise.

The analytic identifies potential enumeration of local network configuration on Linux systems. It detects this activity by monitoring processes such as "arp," "ifconfig," "ip," "netstat," "firewall-cmd," "ufw," "iptables," "ss," and "route" within a 30-minute window. This behavior is significant as it often indicates reconnaissance efforts by adversaries to gather network information for subsequent attacks. If confirmed malicious, this activity could enable attackers to map the network, identify vulnerabilities, and plan further exploitation or lateral movement within the environment.

This rule detects attempts to enumerate local network configuration on Linux systems. It specifically looks for the execution of common network utilities such as 'firewall-cmd', 'ufw', 'iptables', 'netstat', 'ss', 'ip', 'ifconfig', 'systemd-resolve', and 'route'. Additionally, it triggers if '/etc/resolv.conf' is present in the command line, indicating an attempt to inspect DNS resolver configuration.
