Detects the execution of PostgreSQL dump utilities (pg_dump, pg_dumpall) initiated directly by application-level processes like Langflow or Python, rather than through standard system-level task schedulers. This behavior is indicative of unauthorized data collection or staging of database contents by an application process.

Detects instances where LiteLLM, or related Python application processes (uvicorn, python), spawn a shell or command-line utility (bash, sh, id) under the root user account. This behavior is indicative of potential container breakout, application exploitation, or privilege escalation attempts originating from a web-accessible service.

Detects a successful authentication event where standard endpoint identification metadata (endpoint name and IP address) is absent. This often indicates logs originating from sources without proper endpoint telemetry integration or potential attempts to obfuscate the source of an authentication request.

Detects attempts to delete, truncate, or overwrite critical system logs and user command history files (such as /var/log/auth.log, syslog, or .bash_history) on Linux systems using common utilities like rm, shred, and truncate. The rule includes exclusions for legitimate system maintenance processes like logrotate and cron.

This rule detects potentially unauthorized root account activity by monitoring for 'root' logon events and privileged process execution (such as 'su' or 'sudo'). It flags sessions or commands that occur outside of defined business hours, originate from unapproved IP addresses, use unapproved accounts, or are executed via suspicious parent processes, providing a high-confidence indicator of anomalous administrative behavior.

Detects the use of database or archiving command-line utilities to export data related to RADIUS services. The rule filters out known backup service accounts and authorized backup processes, flagging activity that occurs outside of standard business hours or is performed by accounts not explicitly designated for administrative or database maintenance tasks.

Detects access to Gitea secrets and configuration (app.ini, JWT secrets, SSH host keys, deploy keys) via file writes/renames or process command lines referencing those paths alongside Gitea, matching the secret-extraction tradecraft observed in the Red Heron campaign.

Detects potential remote service session hijacking by monitoring for RDP session ID reuse by a different user or unauthorized SSH session reattachment (e.g., tmux/screen hijacking). It correlates logon events with process execution to identify instances where an existing session is accessed by an account other than the original owner, while excluding legitimate service/support account activity.

Detects administrator-privileged actions in JFrog Artifactory audit logs attributed to the 'token:anonymous' identity, the tell-tale signature left when CVE-2026-42018 (unauthenticated token retrieval) is chained with CVE-2026-42016 (privilege escalation) to mint an admin-scope token that retains the anonymous username. Also relevant to CVE-2026-82329 authentication bypass activity.

Detects direct SQL UPDATE operations on the pg_authid system table to modify privilege flags (e.g., rolsuper, rolcreaterole) without using the authorized ALTER ROLE statement. Such activity often indicates an attempt to escalate privileges or modify database user permissions in an unauthorized manner, bypassing standard auditing and role management processes.

This rule monitors for modifications to the PostgreSQL configuration file 'pg_hba.conf', specifically looking for changes that would enable 'trust' authentication, followed by successful database logins using that method within one hour. This behavior is indicative of an attacker modifying authentication rules to gain unauthorized, passwordless access to a database.

Detects the creation or modification of specific files within the /tmp directory, specifically those matching naming patterns associated with 'jasper-log' files or temporary pipe files. These patterns are often associated with temporary storage or data staging activities during post-exploitation or malware execution.

This rule detects attempts by users to disable or clear command line history logs for shell environments, including PowerShell (e.g., modifying PSReadLine history) and Unix-like shells (e.g., unset HISTFILE, setting HISTSIZE to 0, or disabling history collection). Such actions are frequently performed by adversaries to hinder incident response and forensic analysis by obscuring their post-exploitation activity.

Detects processes attempting to access sensitive Linux system files (/etc/passwd or /etc/shadow) that are not typically associated with system administration, security, or identity management tasks. This behavior may indicate an attempt by an unauthorized user or process to gather credentials or system configuration information.

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.
