Detects attempts to perform a container escape via the docker cp command by abusing path traversal vulnerabilities or suspicious file write operations performed by the Docker daemon to the host filesystem outside of standard container paths, often associated with symbolic link extraction exploits.
This rule detects potential container escape attempts utilizing Linux system calls such as 'unshare' or 'clone' with flags indicative of namespace manipulation (CLONE_NEWUSER, CLONE_NEWNET). It also detects the execution of suspected malicious binaries or traffic manipulation tools associated with 'packet_edit_meme' or 'act_pedit' activities, which are common in Linux-based exploitation scenarios.
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 command line sequence used by Miasma to restore passwordless sudo for the 'runner' user in GitHub Actions by overwriting sudoers via a Docker container. This specific pattern targets the Miasma Alpine container payload.
Detects the command line sequence used by Miasma to restore passwordless sudo for the 'runner' user in GitHub Actions by overwriting sudoers via a Docker container. This specific sequence involves echoing 'runner ALL=(ALL) NOPASSWD:ALL' into a file within the /mnt/runner directory and then changing its permissions to 0440, indicative of a privileged modification to the sudoers file within a containerized GitHub Actions runner environment.
Identifies the presence of the known ITScape (CVE-2026-46316) proof-of-concept executable by its SHA256 hash. This vulnerability enables a critical guest-to-host escape affecting ARM64 infrastructure.
Detects deployment of privileged Docker containers that may allow container escape
This rule detects attempts to access the Docker TLS API on port 2376. It triggers an alert if there are 5 or more TCP SYN packets (indicating connection attempts) from a single source to the Docker TLS API port within a 60-second window. This could indicate an attacker attempting to gain unauthorized access or control over Docker containers.
Detects the creation of Kubernetes pods with dangerous security settings that could lead to privilege escalation or container escape. This includes configurations such as enabling hostNetwork, allowing privilege escalation within containers, or running containers as the root user (UID 0).
This rule detects unauthenticated access attempts to the Docker Daemon API, specifically targeting TCP port 2375. It triggers on the initial SYN packet of a TCP connection to this port, indicating an attempt to establish a connection to the Docker API without authentication. This activity is often associated with privilege escalation attempts, as an unauthenticated Docker API can be exploited to gain control over the host system.
Identifies instances where curl is used to interact with a mounted Docker Unix socket. This technique is used to issue API commands directly to the Docker daemon, often to deploy new privileged containers for host escape.
Detects the use of the `nsenter` utility targeting PID 1 to spawn a shell. This is a common container escape technique used to break out of a privileged container and execute commands on the underlying host.
Identifies the use of curl to send POST requests to the Kubernetes API targeting the creation of pods. This can indicate an attacker using a stolen ServiceAccount token to deploy malicious or privileged containers.
Identifies the use of the nsenter utility targeting PID 1 to spawn a shell. This is a common container escape technique used to break out of a privileged container and execute commands on the underlying host.
Detects workloads created with privileged mode, host namespace sharing, dangerous Linux capabilities, Docker socket, containerd socket, or sensitive hostPath mounts. These configurations can be abused by adversaries to escape containers and gain access to the underlying host.
Docker Run/Exec Guardrails Bypass
Cortex XDR
This rule detects the execution of a Docker command with the '--privileged' flag on a Linux system, combined with the execution of specific system information gathering commands. This combination is often indicative of an attempt to escape a container or gain elevated privileges within a containerized environment, potentially leading to host compromise. The '--privileged' flag grants a container nearly all capabilities of the host machine, making it a critical security concern when used maliciously.
Detects the loading of kernel modules using insmod. Executing this from within a container or unexpected context often indicates abuse of CAP_SYS_MODULE to load malicious rootkits or reverse shells for privilege escalation or container escape.
Detects potential user namespace manipulation, a common precursor to kernel namespace exploits like Dirty Frag, by monitoring file modifications to uid_map and gid_map.
etects the full TeamPCP lateral movement pattern: listing secrets across namespaces followed by privileged alpine pod creation in kube-system. Correlation rule.
Detects the execution of devcon.exe with command-line arguments to disable the VMware Virtual Machine Communication Interface (VMCI) PCI device or host device driver. Threat actors use this technique to gain direct hardware access as a preparatory step for VM escape exploits.
Detects multiple crashes from key iOS system processes within a short time window. This pattern is indicative of a failed memory corruption attempt, consistent with the sandbox escape and privilege escalation techniques used by the DarkSword exploit kit.
