Critical containerd CRI Vulnerability (CVE-2026-53488) Leads to Host-Root Command Execution
2 rules 2 TTPsA critical vulnerability (CVE-2026-53488) exists in the containerd CRI plugin where image configuration `LABEL` instructions are propagated to containers without validation, allowing an attacker to inject and execute arbitrary commands with host-root privileges on the underlying host when a maliciously crafted container image is pulled and processed by specific plugins.
Arbitrary Host File Read via Symlink Following in containerd CRI Checkpoint Restore (CVE-2026-53489)
3 rules 2 TTPsA high-severity vulnerability (CVE-2026-53489) in containerd's CRI plugin allows an unprivileged attacker to read arbitrary files on the host system by crafting a malicious checkpoint with a symlink that `containerd` follows during `container.log` restoration, enabling data exfiltration via `kubectl logs`.
Crawl4AI Unauthenticated RCE via Chromium Launch-Argument Injection
3 rules 2 TTPsAn attacker can achieve unauthenticated remote code execution (RCE) in Crawl4AI Docker deployments by injecting malicious Chromium launch arguments, such as `--utility-cmd-prefix` and `--no-zygote`, into the `browser_config.extra_args` field of the API request, allowing for arbitrary command execution as the container's runtime user.

2 rules 7 TTPsA high-severity authentication bypass vulnerability in PraisonAI versions prior to 4.6.61 allows unauthenticated attackers to invoke any registered agent by setting the `PRAISONAI_CALL_AUTH=disabled` environment variable, potentially leading to arbitrary code execution or system compromise.
Kubernetes Static Pod Manifest File Access
3 rules 2 TTPsThis rule detects Linux process executions that reference /etc/kubernetes/manifests in process arguments, which may indicate tampering with static pod manifests for persistence or privilege escalation in Kubernetes environments.
Docker `PUT /containers/{id}/archive` Vulnerability Allows Host Root Code Execution
2 rules 1 TTPA vulnerability exists in Docker where a malicious container image can execute arbitrary code with host root privileges by exploiting the decompression of compressed archives uploaded via the `PUT /containers/{id}/archive` endpoint, tracked as CVE-2026-41567.
Curl or Wget Execution from Container Context
2 rules 1 TTPDetects execution of curl or wget from processes running inside OCI/runc-backed containers, potentially indicating ingress tool transfer or data exfiltration after a container breakout.
Kubectl Secrets Enumeration Across All Namespaces
2 rules 2 TTPsThe rule detects the use of the 'kubectl get secrets --all-namespaces' command, which enumerates secret resources across the entire Kubernetes cluster, potentially aiding credential discovery, privilege escalation, or lateral movement by attackers.
Portainer Bind Mount Restriction Bypass via HostConfig.Mounts (CVE-2026-44850)
2 rules 1 TTPPortainer versions 2.33.0 through 2.33.7, 2.39.0 through 2.39.1, and 2.40.0 through 2.40.9 are vulnerable to CVE-2026-44850, a bind-mount restriction bypass via the `HostConfig.Mounts` array allowing regular users to mount host paths into containers and potentially compromise the host filesystem.
Leveraging Linux Cgroups for Threat Detection and Investigation
2 rulesThis brief outlines how Linux cgroups, a kernel feature for resource management, can be repurposed to provide valuable telemetry for detecting malicious processes, particularly in systemd, Docker, and Kubernetes environments, aiding in investigations of server compromises.
Podman HyperV Machine Vulnerability Allows Arbitrary Code Execution with Administrator Privileges
2 rules 1 TTPA local attacker can exploit a vulnerability in Podman HyperV Machine to execute arbitrary program code with administrator privileges, leading to complete system compromise.
Distribution Toolkit Authentication Redirection Vulnerability (CVE-2026-33540)
2 rules 1 TTP 1 CVEA vulnerability in the distribution toolkit prior to 3.1.0 allows a malicious upstream registry or man-in-the-middle attacker to redirect authentication requests, potentially exposing upstream credentials.
SSH Authorized Key File Modification Inside a Container
2 rules 4 TTPsThe rule detects the creation or modification of an authorized_keys file inside a container, a technique used by adversaries to maintain persistence on a victim host by adding their own public key(s) to enable unauthorized SSH access for lateral movement or privilege escalation.
Suspicious Pod Creation in Kubernetes System Namespace
2 rules 1 TTPAn attacker may deploy a pod within the kube-system namespace in Kubernetes to mimic legitimate system pods and evade detection.
Curl or Wget Execution from Container Context
2 rules 2 TTPsThis rule detects the execution of curl or wget from within runc-backed containers on Linux systems monitored by Auditd Manager, indicating potential ingress tool transfer or data exfiltration by attackers who have compromised the container.
Potential Privilege Escalation in Container via Runc Init
2 rules 1 TTPDetection of runc init child processes with root effective user and non-root login user ID, indicating potential container privilege escalation.
Suspicious Container Runtime CLI Execution
3 rules 2 TTPsThe rule detects execution of container runtime CLI tools (ctr, crictl, nerdctl) with arguments indicating container creation, command execution inside existing containers, image manipulation, or host filesystem mounting, potentially leading to container escape and privilege escalation.
Nsenter to PID Namespace via Auditd
2 rules 1 TTPThis rule detects nsenter executions that target a PID with a namespace target flag, a common pattern used to attach to the host init namespace from a container or session and run with host context, potentially escalating privileges.
Kubelet API Connection Attempt to Internal IP
2 rules 2 TTPsThe rule detects network connection attempts to the Kubernetes Kubelet API ports 10250 and 10255 on internal IP ranges from Linux hosts, indicating potential lateral movement within container and cluster environments.
Container Runtime CLI Execution with Suspicious Arguments
2 rules 2 TTPsDetects execution of container runtime CLI tools (ctr, crictl, nerdctl) with arguments indicating container creation, command execution inside existing containers, image manipulation, or host filesystem mounting, potentially leading to privileged container creation and unauthorized access to sensitive data.
Unusual Process Connecting to Docker or Containerd Socket
2 rules 3 TTPsAn unusual process connecting to a container runtime Unix socket like Docker or Containerd can indicate an attacker attempting to bypass Kubernetes security measures for container manipulation.
Potential Direct Kubelet Access via Process Arguments
2 rules 3 TTPsDetection of potential direct Kubelet access via process arguments in Linux containers, which could lead to enumeration, execution, or lateral movement within the Kubernetes cluster.
