This rule detects attempts to enumerate the 'Domain Admins' group over SMB (Server Message Block) using the 'NetGroupGetUsers' function. This activity is often associated with reconnaissance by attackers trying to identify high-privilege accounts within a Windows domain.
This rule detects attempts to enumerate local administrator groups via a web shell. It specifically looks for HTTP requests containing the string "net localgroup" in the URI, which is a common command used to list local groups on a Windows system. The detection is case-insensitive and targets established HTTP connections from any source to the home network.
This rule detects attempts to enumerate local group memberships on a target system via the Server Message Block (SMB) protocol. Specifically, it looks for the 'NetLocalGroupEnum' function call within SMB traffic directed to the home network on port 445. This activity is often associated with reconnaissance phases of an attack, where an adversary is trying to discover local user groups to identify potential targets for privilege escalation or lateral movement.
This rule detects repeated HTTP requests to 'management.azure.com' with the URI '/resources', indicating an attempt to enumerate Azure resource groups. The threshold of 10 requests within 30 seconds from the same source is set to identify potential scanning or reconnaissance activities.
This rule detects multiple AWS console login attempts from a single source IP address within a short timeframe, specifically looking for access to the 'home' URI on 'console.aws.amazon.com'. This behavior could indicate an attacker attempting to discover cloud resources after gaining initial access to an AWS account.
This rule detects HTTP requests to the AWS EC2 service (ec2.amazonaws.com) that specifically attempt to enumerate Amazon Machine Images (AMIs) using the 'DescribeImages' API call. This activity could indicate an attacker performing reconnaissance to understand the available virtual machine images within an AWS environment.
This rule detects network traffic (specifically HTTP responses) that contains strings indicative of malware attempting to detect the presence of a hypervisor. It looks for the string "GetSystemFirmwareTable" and "VBOX" (case-insensitive) within the file data of the HTTP response. This combination suggests a malware payload checking if it's running in a virtualized environment, specifically VirtualBox, which is a common anti-analysis technique.
This rule detects attempts to query the list of system drivers on a remote Windows host via a WMI session over SMB (port 445). The detection is based on the presence of the string "Win32_SystemDriver" in the network traffic, indicating a WMI query for system driver information. This activity can be indicative of reconnaissance by an attacker.
This rule detects the delivery of a kernel driver enumeration tool via HTTP. Specifically, it looks for the string "EnumDeviceDrivers" (case-insensitive) within HTTP response data flowing to a client. This string is indicative of tools or malware attempting to enumerate loaded kernel drivers, which is a common reconnaissance technique used by attackers.
This rule detects attempts to enumerate device drivers on a system via a web shell. It specifically looks for HTTP requests containing the string "driverquery" in the URI, which is a command-line utility on Windows systems used to display a list of installed device drivers and their properties. The detection is case-insensitive and targets established HTTP connections to the server.
