Detects exploitation attempts against Gitea instances where an attacker impersonates an admin user by injecting the 'X-WEBAUTH-USER' header. This vulnerability typically occurs when 'REVERSE_PROXY_TRUSTED_PROXIES' is misconfigured to trust all proxies ('*'), allowing unauthenticated users to gain administrative access via header manipulation. The rule covers web request headers, container logs for suspicious admin creation, and process execution arguments associated with the exploitation.
Detects execution of the 'docker cp' command containing directory traversal sequences ('../', '..") in the command line arguments. This pattern is indicative of attempts to exploit path traversal vulnerabilities to read or write files outside the intended container scope, potentially leading to container escape.
This rule detects the execution of container runners (act-runner/gitea-act-runner) with insecure container isolation flags, such as mounting the host root filesystem, disabling security profiles (seccomp/apparmor), or running with host namespaces and excessive capabilities. These configurations indicate potential container escape attempts or misconfigurations that allow significant host-level access.
Detects the exploitation of CVE-2026-20896 in Gitea, where an unauthenticated attacker sends a crafted POST request to user registration or installation endpoints. The rule triggers when this network activity is followed by the creation of a new user account with administrative roles within a 10-minute window, indicating potential privilege escalation.
This rule detects potential Mythic C2 implant or payload build activity occurring via Docker. It monitors for executions of docker.exe, docker-compose.exe, or docker commands initiated by shells (cmd.exe, powershell.exe) containing keywords associated with the Mythic C2 framework, while explicitly excluding common CI/CD runner parent processes to reduce noise.
This rule detects potentially malicious activity within Linux environments or containers where a single user context concurrently performs credential hunting (via environment variable dumping or accessing .env files) and terminates processes associated with known cryptocurrency miners or competing malicious actors. This behavior is highly indicative of a cryptojacking infection or a malicious actor clearing out existing resource-hijacking threats.
This rule detects potentially malicious web requests attempting to access sensitive local system files, environment variables, or application source code within a cloud-hosted application environment. The detection logic focuses on URI patterns indicative of Local File Inclusion (LFI) attempts targeting proc filesystem nodes, credential configuration files, or application source bundles.
Detects potential SSRF or local file read attempts by identifying requests to sensitive system or application file paths (e.g., /proc/self/environ, /etc/passwd) that result in an unusually large response body compared to the historical baseline for that endpoint.
Detects incoming HTTP requests that use URL-encoding (e.g., %2e%2e, %2f) to obfuscate path traversal sequences targeting sensitive operating system or container application files, such as /proc/self/environ or /etc/passwd. This technique is often used to bypass security filters or URL validation mechanisms in web applications.
Detects a suspicious sequence of events where a Gitea act_runner process spawns a container with dangerous namespace or capability flags (e.g., --pid=host, --cap-add=ALL) followed by the execution of 'nsenter' in the same environment, indicating an attempt to escape the container to the host.
Detects Gitea act_runner spawning Docker containers with dangerous runtime flags (e.g., --pid=host, --privileged, --cap-add=ALL) that facilitate host namespace escape. This activity is indicative of exploitation of CVE-2026-20896, where malicious CI/CD workflow YAML files inject these options to break out of the container sandbox and access the host filesystem.
Detects the use of the 'cp' command within a Docker container context to access files outside the current working directory, identified by the usage of parent directory traversal (..). This pattern is often associated with container escape attempts or unauthorized file access within a containerized environment.
Detects the execution of Gitea/Act runner or Docker containers with dangerous configurations that allow host-level access, such as privileged mode, host PID/IPC namespaces, or disabled security profiles (AppArmor/Seccomp). These configurations are often used to escape container isolation or execute commands on the underlying host.
This rule detects activities indicative of a Docker container escape, specifically targeting the 'docker cp' path traversal vulnerability. It monitors for suspicious command-line patterns involving path traversal sequences ('../'), execution of shells or common utilities from container-related processes (dockerd, containerd, etc.), and the presence of known proof-of-concept artifacts or files written outside the expected container boundary.
Detects potentially malicious container escape or privilege escalation attempts initiated by Gitea act runner processes. This includes the spawning of 'nsenter', the use of dangerous Docker flags that provide host-level access (such as host PID/IPC namespaces, all capabilities, or disabled security mechanisms), and the spawning of shells inside containers configured with namespace-entering commands.
Detects exploitation attempts against CVE-2026-33017 in Langflow by monitoring for unauthenticated POST requests to the /api/v1/build_public_tmp/ endpoint, specifically using the identified exploit User-Agent, followed by outbound connections from the victim host to known attacker-controlled infrastructure.
Detects potential container escape attempts leveraging path traversal vulnerabilities in the 'docker cp' command (e.g., CVE-2026-55199). The rule identifies file creation events triggered by docker processes where the target file path is outside the expected Docker root or temporary directory structures, suggesting an effort to write files to arbitrary locations on the host filesystem.
This rule detects potential Mythic C2 implant or payload build activity occurring via Docker. It monitors for executions of docker.exe, docker-compose.exe, or docker commands initiated by shells (cmd.exe, powershell.exe) containing keywords associated with the Mythic C2 framework, while explicitly excluding common CI/CD runner parent processes to reduce noise.
This rule detects potential container escape attempts on Linux systems by monitoring suspicious file system access patterns to the host's root directory or process creation events involving 'mount', 'nsenter', or 'chroot' commands with parameters indicative of host interaction. Specifically, it looks for file operations on '/proc/1/root', '/proc/1/cwd', '/proc/1/exe', '/proc/1/fd', '/proc/1/ns', '/proc/1/environ', '/proc/1/mounts' or paths starting with '/host', '/hostroot', '/host-root', '/node-root'. It also flags 'mount' commands targeting '/proc/1/root', '/proc/1', 'nsenter', '--target 1', 'hostpath', or '/host', 'nsenter' commands with namespace manipulation arguments, and 'chroot' commands targeting '/proc/1/root', '/host', or '/hostroot'. These activities are commonly associated with adversaries trying to break out of a containerized environment to gain access to the underlying host.
Detects the suspicious combination of 'aa-exec' (commonly associated with AppArmor or specific container runtime wrappers) being followed by the execution of 'unshare' with flags used to manipulate kernel namespaces (user, network). This pattern is often indicative of container breakouts or privilege escalation attempts where an adversary leverages namespace isolation to gain higher privileges on the host.
This rule monitors process execution events for the 'aa-exec' utility, a tool often used in containerized environments (such as AppArmor) or specific runtime configurations, when invoked with specific command-line arguments (-p trinity, -p chrome, or -p flatpak). These patterns are indicative of specialized container or sandbox execution activities that may warrant investigation in specific enterprise environments.
