Detects anomalous process execution where a non-privileged process spawns a child process with root/SYSTEM (uid 0) privileges without passing through recognized elevation binaries (e.g., sudo, su, pkexec). This behavior is consistent with post-exploitation privilege escalation techniques, such as exploiting hijacked file descriptors or callback structures to gain root authority.

Detects anomalous attempts to silently reinstall an APK or modify accessibility settings via a local ADB shell daemon (identified by specific local-service file paths). This behavior is characteristic of Android malware, such as RatHat, attempting to maintain persistence and gain unauthorized permissions.

This rule monitors for potential exploitation of AI supply chain vulnerabilities, specifically targeting AML.T0058 (Publish Poisoned Models). It identifies the download of suspicious model artifact files (e.g., .pt, .pkl, .h5, .onnx) via common tools like curl, wget, or pip, and detects the subsequent insecure deserialization of these files using Python's pickle library when dangerous opcodes (REDUCE/GLOBAL) are combined with system command execution primitives (os.system, subprocess).

This rule detects potential supply chain compromise by monitoring for the installation of pip or npm packages with names similar to popular AI/LLM frameworks (e.g., langchain, llamaindex, mastra, litellm). It then correlates these installations with subsequent suspicious activity, including potential beaconing to external IPs, execution of known crypto-miners, or access to sensitive local files (e.g., AWS credentials, SSH keys).

Detects the installation of AI agent-related packages (npm, pip, etc.) followed shortly by unauthorized access to sensitive files or credential stores on the same host. This pattern is indicative of a malicious or 'poisoned' AI agent tool performing credential theft or unauthorized exfiltration of sensitive system data.

Detects the use of 'COPY TO PROGRAM' syntax within Cisco Email Security Appliance (ESA) logs. This pattern is indicative of potential command injection or OS command execution attempts often associated with exploitation of database-related functionalities, specifically targeting Cisco ESA management or backend interfaces.

This behavior is consistent with post-exploitation privilege escalation techniques, such as exploiting hijacked file descriptors or callback structures to gain root authority.

Detects anomalous process execution patterns involving netkit devices and virtual network interfaces (VXLAN/OVS) configured with oversized headroom, characteristic of the TUNderflow (CVE-2026-81000) exploitation chain. The rule monitors for the staging of netkit devices and specific OVS command-line interactions by non-privileged accounts, excluding known legitimate SDN and CNI infrastructure management processes.

Detects interactive root shell requests via 'sudo -i' that occur shortly after a failed Parallels appliance installation or tar extraction event containing specific error codes or configuration markers (UCP_UID=0). This pattern aligns with the exploitation chain for CVE-2026-90894, where an attacker leverages an extraction failure to escalate privileges.

Detects a suspicious scenario where a non-root process associated with Acronis backup plugins (typically used on cPanel, WHM, or Plesk servers) spawns a child process that executes with root privileges. This behavior is indicative of potential privilege escalation exploiting CVE-2026-87886.

The following analytic identifies the use of the esxcli system auditrecords commands, which can be used to tamper with logging on an ESXi host.
This action may indicate an attempt to evade detection or hinder forensic analysis by preventing the recording of system-level audit events.

Detects local privilege escalation attempts targeting Acronis backup plugins for cPanel, WHM, and Plesk. The rule monitors for instances where backup-related processes or binaries located within control panel paths are executed with root privileges when the parent process was not originated by root, a behavior indicative of exploiting insecure file permissions.

Detects the execution of a shell process (sh, bash, dash, zsh) spawned as a child of Acronis backup agent or plugin processes by the root user. This behavior is indicative of potential exploitation of local privilege escalation vulnerabilities, such as CVE-2026-87886, within Acronis backup plugins for cPanel, WHM, and Plesk.

Detects potential exploitation of CVE-2026-87886 in the Acronis Backup plugin for cPanel & WHM, where an adversary uses insecure file permissions to elevate privileges. The rule monitors for execution of file permission or ownership changing utilities (chmod, chown) targeting files associated with backup plugins.

Detects instances where a Gradle or Java build process invokes a shell (sh -c) containing suspicious build-related keywords such as 'preBuild', 'doLast', or 'tasks.all'. This pattern is commonly observed in supply chain compromises where malicious code is injected into build scripts to execute hidden payloads during the compilation phase.

This rule detects when common web server service accounts (e.g., www-data, apache) spawn Unix shell processes (sh, bash, dash) to execute system enumeration commands like 'id' or 'whoami'. This activity is often a sign of post-exploitation behavior following successful web application exploitation, where an attacker attempts to determine their context and privileges on the compromised host.

Detects anomalous staging activity associated with the 'PPPoEject' exploit. The rule identifies the creation of GRE or IP6GRE interfaces on bonding devices immediately preceding or concurrent with FUSE filesystem mounting or I/O activity. This pattern matches the exploitation workflow of racing pppoe_sendmsg() skb reallocation via dev_hard_header() to achieve privilege escalation.
