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 SSH persistence planted during the Red Heron campaign: authorized_keys file writes under a .ssh folder, correlated with process command lines referencing authorized_keys and the operator's observed key comment naming pattern (backdoor / root-shell).

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 the execution of s5cmd.exe with command line arguments indicative of data transfer operations (sync, cp, mv, run) to or from an 's3://' URI. s5cmd is a high-performance command-line tool frequently used for parallel S3 operations, which may be leveraged by adversaries for rapid data exfiltration or staging.
This rule detects high-frequency account and email address enumeration attempts. It monitors syslog data for SMTP commands such as VRFY, EXPN, or RCPT TO, and analyzes Microsoft Entra ID (SigninLogs) for authentication failures specifically associated with error code 50034 (user not found). Both behaviors are indicative of an adversary attempting to validate user identities within an environment, often as a precursor to targeted phishing or brute-force attacks.
Detects anomalous, high-volume unauthenticated POST requests to the Elementor Pro 'admin-ajax.php' endpoint with the 'elementor_pro_forms_send_form' action. This behavior is indicative of potential exploitation attempts or reconnaissance associated with the Elementor Pro file upload vulnerability (CVE-2026-32475).
Detects instances where base64-encoded PHP code, obfuscated behind a 'data:image/gif;base64' MIME type prefix, is written to the disk as a .php file or initiated by web server processes. This pattern is commonly used in file upload bypass attacks to execute arbitrary code.
Detects potential exploitation of PostgreSQL via logical decoding plugins, specifically targeting CVE-2026-6471. The rule monitors for the PostgreSQL server process spawning suspicious shell utilities or loading modules from locations outside of the expected PostgreSQL library or plugin directories, which is a common indicator of unauthorized code execution.
Detects usage of the 'gem' command (install, build, push, publish) that includes naming patterns or specific command strings associated with the GemStuffer supply chain compromise campaign. This targets attempts to introduce malicious dependencies into the environment using RubyGems.
Detects the execution of Ruby or Yard processes where specific command-line arguments (e.g., --load) are used to invoke potentially malicious Ruby script files like evil.rb, loader.rb, or script.rb. This pattern is indicative of an adversary leveraging existing legitimate tools to execute arbitrary script code.
Detects high-volume outbound network traffic (exceeding 100MB) generated by processes identifying as 'python-httpx' to non-internal IP addresses. This activity is often associated with automated data exfiltration using Python-based tools.
This rule monitors for file creation or modification events related to the Admin Menu Editor Pro WordPress plugin, specifically looking for indicators of specific versions (2.35, 2.36) or file naming conventions. It also alerts on network communication to the plugin's domain, which could indicate a compromise or the use of an unauthorized or modified plugin version that may be associated with known vulnerabilities.
Detects the presence of PHP web shell code within the Admin Menu Editor Pro WordPress plugin directory. This rule targets indicators of a supply chain compromise where a legitimate plugin update is backdoored to include malicious PHP code designed for remote command execution via HTTP requests.
Detects individual process-level invocations of Microsoft Graph API endpoints commonly used for reconnaissance of user, group, and role information. This rule acts as a precursor signal to identify potential enumeration activities within an Office 365 environment.
Detects instances where a process running as 'root' modifies files within an Acronis-related directory. This specifically alerts when the modifying process is not identified as a known, authorized Acronis backup service, potentially indicating unauthorized tampering with backup archives or configuration files.
Detects web server processes invoking user creation scripts or functions specifically associated with the 'admin-menu-editor-pro' WordPress plugin. This activity is indicative of an attacker attempting to create a new administrative user account after exploiting a vulnerable WordPress plugin or site configuration.
Detects attempts to exploit a vulnerability in WSO2 API Manager and Traffic Manager that allows for authentication bypass by utilizing a malformed JWT with the 'alg=none' header. Attackers can leverage this to impersonate users or bypass security controls by providing a crafted Bearer token in the Authorization header.
Detects high-frequency outbound TCP connection attempts from a WSO2 API Gateway or Traffic Manager host to multiple sensitive internal management and administrative ports (22, 445, 3389, 5985, 5986). This behavior is indicative of a compromised gateway being used for lateral movement across the network.
Detects download or installation attempts of specific trojanized versions (2.35 and 2.36) of the Admin Menu Editor Pro plugin, which were distributed via a compromised update channel on adminmenueditor.com.
