This rule detects the creation of a systemd timer via a remote SSH session. It specifically looks for TCP traffic on port 22 (SSH) containing the commands 'systemctl enable' and '.timer' (case-insensitive), indicating an attempt to enable a systemd timer unit.
This rule detects attempts to hijack the clipboard on a web page by identifying HTTP responses (flow:to_client) that contain both 'clipboardData' and 'setData' (case-insensitive) in the file data. This combination of keywords suggests a script attempting to read from and write to the client's clipboard, which is a common technique for clipboard hijacking.
This rule detects HTTP traffic where a shortened URL (from services like bit.ly, tinyurl, ow.ly, or t.co) is used in the HTTP referer header, and the HTTP response body contains the 'MZ' magic bytes, indicating a Windows executable file. This combination suggests a malicious redirect leading to the download of a payload, often associated with phishing or drive-by download attacks.
This rule detects the deployment of a new privileged container via the Docker API. It specifically looks for HTTP requests to the '/containers/create' endpoint with 'Privileged' in the client body, indicating an attempt to create a container with elevated privileges. This activity can be indicative of an attacker attempting to gain higher access or persistence within a compromised system by deploying a malicious container.
This rule detects when a 'docker exec' command is run against a running container. It specifically looks for HTTP POST requests to the '/exec' endpoint, which is used by the Docker API to create and start an exec instance inside a container. This activity could indicate an attacker gaining interactive access to a compromised container.
This rule detects potential macOS XPC Service abuse via remote SSH. Specifically, it looks for TCP traffic on port 22 (SSH) within the home network that contains the strings "launchctl" and "submit" (case-insensitive). This combination suggests an attempt to use the launchctl command to submit a job, potentially exploiting XPC services, over an SSH connection.
This rule detects the download of a file over HTTP that contains the string "=cmd|" (case-insensitive) within its data. This pattern is indicative of a DDE (Dynamic Data Exchange) formula injection attempt, often used in Office documents to execute commands.
This rule detects attempts by users to download fake software cracks, keygens, activators, patches, or serials from HTTP servers. It specifically looks for HTTP responses containing URIs with keywords like 'crack', 'keygen', 'activator', 'patch', or 'serial' (case-insensitive) and verifies that the downloaded file data starts with 'MZ', indicating a Windows executable. This combination suggests a user is downloading potentially malicious software disguised as a legitimate software cracking tool.
This rule detects an attempt to access the ESXi direct SSH shell by looking for the 'vim-cmd' string in TCP traffic directed to port 22 (SSH) on the home network. This indicates an administrative command being executed directly on an ESXi host via SSH.
This rule detects attempts to enable the ESXi Host Shell via the vCenter Web API. It specifically looks for HTTP requests to the '/api/vcenter/host' URI containing the word 'shell' in the client body, indicating a potential administrative action to enable shell access on an ESXi host.
