This rule detects attempts to push firmware or bootkit images to a device via a remote SSH session. It specifically looks for the commands 'dd if=' and '/dev/' within TCP traffic directed to port 22 (SSH), indicating an attempt to write data directly to a device file, which is a common method for flashing firmware or installing bootkits.
This rule detects attempts to execute AppleScript commands remotely over SSH. It specifically looks for the string "osascript" (case-insensitive) within TCP traffic destined for port 22 (SSH) on the home network, indicating a potential remote execution of AppleScript.
This rule detects attempts to write or modify cron persistence entries via HTTP. Specifically, it looks for HTTP client body content containing the string "/etc/cron" (case-insensitive). This indicates a potential attacker trying to establish persistence on a Linux system by scheduling malicious tasks.
This rule detects the delivery of a Lua script payload via HTTP. It specifically looks for HTTP responses containing '.lua' in the URI and the string 'os.execute(' within the file data, indicating an attempt to execute commands on the client system. This is often associated with trojan activity.
This rule detects HTTP POST requests to the Google Cloud Platform (GCP) Compute Engine API (compute.googleapis.com). It specifically looks for a high volume of these requests (20 within 10 seconds from the same source IP), which could indicate automated activity or potential command execution attempts within GCP. The rule is designed to identify suspicious interactions with the GCP API that might be related to execution tactics.
This rule detects network traffic on TCP port 830, which is commonly used for NETCONF (Network Configuration Protocol) sessions. The rule specifically looks for the string "<rpc" within the traffic, indicating an RPC (Remote Procedure Call) request, which is a fundamental part of NETCONF communication. This suggests an attempt to establish a CLI (Command Line Interface) session with a network device using NETCONF.
This rule detects attempts to fetch Python package files (setup.py or __init__.py) from pypi.org over HTTP. This activity could indicate a client attempting to download or interact with Python packages, potentially including malicious ones, from the Python Package Index. The rule uses a threshold to alert on frequent occurrences from the same source.
This rule detects remote activation of COM objects via DCOM (Distributed Component Object Model) on TCP port 135. It specifically looks for the byte sequence '|05 00 0b|' and the string 'IDispatch' within the network flow, indicating an attempt to interact with COM objects remotely. This activity can be associated with lateral movement or execution techniques by attackers.
This rule detects attempts to pull a Docker image via an unauthenticated Docker API. Specifically, it looks for HTTP requests to the '/images/create' endpoint on port 2375, which is the default unauthenticated Docker API port. This activity could indicate an attacker exploiting an exposed Docker daemon to deploy malicious images or gain further access to the host system.
This rule detects attempts to spawn a shell inside a container via the Docker API. Specifically, it looks for HTTP traffic directed to port 2375 (commonly used for the Docker API) containing the string "/bin/sh" in the client body, indicating a command to execute a shell.
