This rule detects potential adversary-in-the-middle (AiTM) or device-code authentication attacks where a user reports suspicious vishing (voice phishing) or SMS lures involving passkeys or SSO updates. The rule correlates user-reported social engineering pretexts with evidence of risky authentication flows, such as device code usage or specific authentication error codes associated with interception.
Detects anomalous, high-frequency file access (100+ files within a 2-hour window) in Microsoft 365 (SharePoint or OneDrive) by users employing a Python-based HTTP client (python-httpx). This behavior is often indicative of automated data scraping, exfiltration, or bulk download activities performed by unauthorized scripts or compromised service accounts.
This rule identifies instances where a user successfully authenticates using a phone app OTP MFA method that was registered between 1 and 30 days prior. The rule specifically flags logins associated with potentially automated or non-browser user agents, or logins flagged with risk, suggesting potential account takeover or persistence mechanisms involving MFA re-registration.
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 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.
Detects a multi-stage cloud attack sequence involving a sign-in anomaly, modification of user authentication methods (e.g., registering an attacker-controlled device), reconnaissance using Microsoft Graph API, and subsequent abnormal data access/download, typically observed in Storm-3121 and Storm-3032 activities.
This rule identifies instances of the Acronis backup plugin for cPanel, WHM, or Plesk running on versions older than 1.9.3 HF3. This versioning threshold corresponds to the patch level required to mitigate the security vulnerability identified as CVE-2026-87886.
Detects network traffic directed towards Microsoft Graph API that utilizes the 'python-httpx' User-Agent. This combination is often associated with automated scripts, potentially used by adversaries (e.g., Storm-3121/Storm-3032) for automated data collection and exfiltration from Microsoft 365 environments.
