Detects anomalous Agentforce session activity where a user, via the General CRM subagent, queries Lead records followed shortly by an access request to Account records. This pattern is indicative of a potentially hijacked agent session attempting to pivot from lead review into unauthorized data access of broader customer information.
Detects high-volume file access or download operations in SharePoint or OneDrive performed by common scripting libraries and client user agents, which may indicate automated data exfiltration.
Detects bulk read operations on AWS Secrets Manager or similar cloud secret stores where the accessed resources contain keywords related to cryptocurrency custody, private keys, or wallet material. This pattern is indicative of unauthorized exfiltration attempts by threat actors such as Slim Spider targeting digital asset infrastructure.
Detects high-frequency access to mail items via specific client applications, or high-frequency file downloads/access within SharePoint and OneDrive. These patterns may indicate suspicious data collection or exfiltration attempts by a compromised account.
Detects bulk read operations on AWS Secrets Manager or similar cloud secret stores where the accessed resources contain keywords related to cryptocurrency custody, private keys, or wallet material. This pattern is indicative of unauthorized exfiltration attempts by threat actors such as Slim Spider targeting digital asset infrastructure.
Detects a single identity listing access keys for a high volume (20+) of Azure Storage Accounts within a 15-minute window. This behavior is indicative of credential harvesting, reconnaissance, or automated exfiltration attempts targeting storage resources.
Detects anomalous, high-volume file access or download activity in Microsoft SharePoint Online or OneDrive for Business originating from a 'python-httpx' user agent. This pattern often indicates automated data collection or exfiltration attempts using programmatic tools.
This rule detects potentially unauthorized access or downloading of files from SharePoint and OneDrive, as well as specific MailItemsAccessed events associated with known exfiltration toolkit patterns within Microsoft 365. It flags individual events matching these criteria as a baseline for identifying suspicious data access behaviors.
Detects high-frequency search queries in SharePoint that utilize internal document identifiers (indexdocid), which may indicate an adversary attempting to enumerate or scrape content across a site collection.
Detects anomalous large-volume file download or export activity from cloud repositories (SharePoint, OneDrive, or Salesforce) occurring shortly after a help-desk-mediated credential or MFA reset for the same user. This behavior is indicative of account takeover, specifically vishing-to-exfiltration patterns used by threat actors.
Detects instances where Microsoft 365 Copilot surfaces content labeled with sensitivity markings to a user who only has access to that content via inherited or broad sharing permissions (e.g., Company link, Anonymous link, or inherited permissions), rather than explicit access. This identifies potential AI-retrieval exploitation patterns where Copilot inadvertently exposes sensitive information due to oversharing configurations.
Detects anomalous large-volume file download or export activity from cloud repositories (SharePoint, OneDrive, or Salesforce) occurring shortly after a help-desk-mediated credential or MFA reset for the same user. This behavior is indicative of account takeover, specifically vishing-to-exfiltration patterns used by threat actors.

Detects anomalous Agentforce session activity where a user, via the General CRM subagent, queries Lead records followed shortly by an access request to Account records. This pattern is indicative of a potentially hijacked agent session attempting to pivot from lead review into unauthorized data access of broader customer information.
Detects high-volume file and data access events within Microsoft 365 services (SharePoint, OneDrive, Exchange) originating from Python-based user agents (e.g., 'python-requests', 'python-httpx'). This pattern is indicative of automated scraping, data exfiltration, or bulk activity performed by unauthorized scripts.
Detects bulk read operations on AWS Secrets Manager or similar cloud secret stores where the accessed resources contain keywords related to cryptocurrency custody, private keys, or wallet material. This pattern is indicative of unauthorized exfiltration attempts by threat actors such as Slim Spider targeting digital asset infrastructure.
Detects rapid access to multiple Microsoft 365 collection applications (Office, OneDrive, Teams) by a user account from specific AWS EC2 IP ranges identified as associated with the TeamFiltration tool. This behavior is consistent with automated exfiltration of email, chats, and files.
Detects anomalous database activity involving the creation of 'ZQ'-prefixed staging tables followed by a high-volume drop operation across multiple tables within a short timeframe. This behavior is indicative of data staging for potential exfiltration followed by an attempt to delete evidence or clear tracks.
This rule identifies sustained, low-volume activity (low-and-slow) against Microsoft 365 services (SharePoint, OneDrive, and Exchange) which may indicate an adversary is using automated methods via the Graph API to collect sensitive files or emails over an extended period. The rule buckets events by user and time, requiring a minimum of three hours of activity with consistent but low-volume interactions to identify potential data collection behavior that avoids traditional volume-based detection thresholds.
Detects high-volume, potentially automated data access, collection, or staging activities within Microsoft 365 services (SharePoint, OneDrive, and Exchange). The rule flags user identities performing a high count of operations (downloads, accesses, deletions, or export requests) across a wide range of unique objects or sites within a one-hour window, which is indicative of post-compromise mass data collection or exfiltration preparation.
